Trespass to chattels is a tort whereby the infringing party has intentionally (or, in Australia, negligently) interfered with another person's lawful possession of a chattel (movable personal property). The interference can be any physical contact with the chattel in a quantifiable way, or any dispossession of the chattel (whether by taking it, destroying it, or barring the owner's access to it). As opposed to the greater wrong of conversion, trespass to chattels is argued to be actionable per se.

The origin of the concept comes from the original writ of trespass de bonis asportatis. As in most other forms of trespass, remedy can only be obtained once it is proven that there was direct interference regardless of damage being done, and the infringing party has failed to disprove either negligence or intent.

In some common-law countries, such as the United States and Canada, a remedy for trespass to chattels can only be obtained if the direct interference was sufficiently substantial to amount to dispossession, or alternatively where there had been an injury proximately related to the chattel. (Restatement (Second) of Torts, 1965.)

United States law.

The Restatement of Torts, Second § 217 defines trespass to chattels as "intentionally… dispossessing another of the chattel, or using or intermeddling with a chattel in the possession of another." Harm to personal property or diminution of its quality, condition or value as a result of a defendant's use can also result in liability under § 218(b) of the Restatement.

Certain specific circumstances may lend themselves to liability for the action. The Restatement (Second) of Torts § 218 states further that:

One who commits a trespass to a chattel is subject to liability to the possessor of the chattel if, but only if,

a. he dispossesses the other of the chattel, or

b. the chattel is impaired as to its condition, quality, or value, or

c.  the possessor is deprived of the use of the chattel for a substantial time, or

d. bodily harm is caused to the possessor, or harm is caused to some person or thing in which the possessor has a legally protected interest.

The trespass to chattels cause of action, frequently asserted in recent years against Internet advertisers and email spammers, is often included in complaints against spyware companies. These electronic messaging cases, and their progeny, which have cropped up over the last decade, will typically turn on the situations described in (b) or (d), and, as detailed below, the question of harm caused is a big issue.

In sum, the basic elements of a claim of trespass to chattels are: 1) the lack of the plaintiff's consent to the trespass, 2) interference or intermeddling with possessory interest, and 3) the intentionality of the defendant's actions. Actual damage is not necessarily a required element of a trespass to chattels claim.

Features of the claim.

Lack of consent.

A vendor can attempt to dispute a trespass claim on the grounds that the user consented to the terms of the contract. Even if consent was given for certain access, a user may still have a valid trespass to chattels complaint if the vendor has exceeded the contractual terms, if the contract is found to misrepresent the actual functioning of the product, or if the consent has been withdrawn. A vendor can be held liable for "any use exceeding the consent" given.

Exemptions and tax rates.

 As noted before, a certain amount of each estate is exempted from taxation by the law. Below is a table of the amount of exemption by year an estate would expect. Estates above these amounts would be subject to estate tax, but only for the amount above the exemption.

For example, assume an estate of $3.5 million in 2006. There are two beneficiaries who will each receive equal shares of the estate. The maximum allowable credit is $2 million for that year, so the taxable value is therefore $1.5 million. Since it is 2006, the tax rate on that $1.5 million is 46%, so the total taxes paid would be $690,000. Each beneficiary will receive $1,000,000 of untaxed inheritance and $405,000 from the taxable portion of their inheritance for a total of $1,405,000. This means the estate would have paid a taxable rate of 19.7%.

As shown below, the 2001 tax act would have repealed the estate tax for one year (2010) and would then have readjusted it in 2011 to the year 2002 exemption level with a 2001 top rate. That is, had no further legislation been passed, the estate of a person who died in the year 2010 would have been entirely exempt from tax while that of a person who died in the year 2011 or later would have been taxed as heavily as in 2001. However, on December 17, 2010, Congress passed the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010. Section 301 of the 2010 Act reinstated the federal estate tax. The new law set the exemption for U.S. citizens and residents at $5 million per person, and it provided a top tax rate of 35 percent for the years 2011 and 2012.

On January 1, 2013, the American Taxpayer Relief Act of 2012 was passed which permanently establishes an exemption of $5 million (as 2011 basis with inflation adjustment) per person for U.S. citizens and residents, with a maximum tax rate of 40% for the year 2013 and beyond.

The permanence of this regulation is not ensured: the fiscal year 2014 budget called for lowering the estate tax exclusion, the generation-skipping transfer tax and the gift-tax exemption back to levels of 2009 as of the year 2018. The exemption amounts of $11,180,000 in 2018 and $11,400,000 in 2019 are also currently (as of December 2018) scheduled to sunset 12/31/2025 (Tax Cuts and Jobs Act of 2017).

Puerto Rico and other U.S. possessions.

A decedent who is a U.S. citizen born in Puerto Rico and resident at the time of death in a U.S. possession (i.e., PR) is generally treated, for federal tax purposes, as though he or she were a nonresident who is not a citizen of the United States, so the $5 million exemption does not apply to such a person's estate. For U.S. estate tax purposes, a U.S. resident is someone who had a domicile in the United States at the time of death. A person acquires a domicile by living in a place for even a brief period of time, as long as the person had no intention of moving from that place.

Hostile possession.

The disseisor must have entered or used the land without permission from the true owner. The disseisor's motivations may be interpreted by the court in several ways, depending upon state law and precedent:

Objective view – the land was used without the true owner's permission and in a manner inconsistent with the true owner's rights.

Bad faith or intentional trespass view – the land was used with the adverse possessor's subjective intent to disregard or violate the actual property owner's rights.

Good faith view – a few states require that the party claiming adverse possession must have mistakenly believed that it is their land.

Some jurisdictions permit accidental adverse possession, as might occur as the result of a surveying error that places the boundary line between properties in the wrong location.

Renters, hunters or others who enter the land with permission are not taking possession that is hostile to the title owner's rights. (mistaken possession in some jurisdictions does not constitute hostility)

Open and notorious use.

The disseisor must possess the property in a manner that is capable of being seen. That is, the disseisor's use of the property must be sufficiently visible and apparent that it gives notice to the legal owner that someone may assert claim, and must be of such character that would give notice to a reasonable person. If the legal owner has actual knowledge of the use, this element is met; it can be also met by fencing, opening or closing gates or an entry to the property, posted signs, crops, buildings, or animals that a diligent owner could be expected to know about.

Continuous.

The disseisor claiming adverse possession must hold that property continuously for the entire statute of limitations period, and use it as a true owner would for that time.

Generally, the disseisor's openly hostile possession must be continual (although not necessarily constant) without challenge or permission from the lawful owner, but breaks in use that are consistent with how an owner would use the property will not prevent an adverse possession claim. Occasional activity on the land with long gaps in activity fails the test of continuous possession; courts have ruled that merely cutting timber at intervals, when not accompanied by other actions that demonstrate actual and continuous possession, fails to demonstrate continuous possession. If at any time during the statute of limitations period, the true owner ejects the disseisor from the land either verbally or through legal action, and the disseisor then returns and dispossesses him again, then the statute of limitations period begins anew.

The statute of limitations applies only to the disseisor's time on the property, not how long the true owner may have been dispossessed of it (by, say, another disseisor who then left the property). However, if adverse possession is continuous between two or more successive disseisors without interruption, it may be possible for the second disseisor to claim adverse possession for the entire period based upon a legal doctrine known as tacking.

In Western jurisprudence, concurrence (also contemporaneity or simultaneity) is the apparent need to prove the simultaneous occurrence of both actus reus ("guilty action") and mens rea ("guilty mind"), to constitute a crime; except in crimes of strict liability. In theory, if the actus reus does not hold concurrence in point of time with the mens rea then no crime has been committed.

Discussion.

Suppose for example that the accused accidentally injures a pedestrian while driving. Aware of the collision, the accused rushes from the car only to find that the victim is a hated enemy. At this point, the accused joyfully proclaims his pleasure at having caused the injury. The conventional rule is that no crime has been committed. The actus reus is complete, and no rule of ratification applies in the criminal law. Whereas in the law of agency, a principal may retrospectively adopt a transaction as if the agent had originally been authorised to conclude an agreement with a third party ("ratification" of the agent's decision), and so acquires liability under that agreement, an alleged criminal cannot retrospectively adopt an actus reus and acquire guilt. To be convicted, the accused must have formed the mens rea either before or during the commission of the actus reus. In the vast majority of cases, this rule works without difficulty.

Two types of concurrence in criminal law

1. Temporal concurrence – the actus reus and mens rea occur at the same time.

2.  Motivational concurrence – the mens rea motivates the actus reus.

The problem.

Not all events are limited to a particular moment in time. The normal physical rules of cause and effect may see a series of interlocking circumstances conspire to cause a particular injury. If the facts of the example above are slightly changed so that the accident occurs at night at a sharp bend on a very quiet country road. When the driver sees the victim lying in the road, he simply leaves the unconscious person where he fell. Some hours later, when a second car innocently comes around the corner and kills the victim, the first driver is happily asleep in his bed. Thus, he argues that, at the time of the death, he had no mens rea and so cannot be guilty of homicide. This argument fails because of the so-called Single Transaction Principle.

In jurisprudence, duress or coercion refers to a situation whereby a person performs an act as a result of violence, threat, or other pressure against the person. Black's Law Dictionary (6th edition) defines duress as "any unlawful threat or coercion used... to induce another to act  in a manner  otherwise would not ". Duress is pressure exerted upon a person to coerce that person to perform an act they ordinarily would not perform. The notion of duress must be distinguished both from undue influence in the civil law. In criminal law, duress and necessity are different defenses.

Duress has two aspects. One is that it negates the person's consent to an act, such as sexual activity or the entering into a contract; or, secondly, as a possible legal defense or justification to an otherwise unlawful act. Defendants utilizing the duress defense admit to breaking the law but claim that they are not liable because, even though the act broke the law, it was only performed because of extreme, unlawful pressure. In criminal law, a duress defense is similar to a plea of guilty, admitting partial culpability, so that if the defense is not accepted then the criminal act is admitted.

Duress or coercion can also be raised in an allegation of rape or other sexual assault to negate a defense of consent on the part of the person making the allegation.

Discussion.

A defendant who raises a defense of duress has actually done everything to constitute the actus reus of the crime, and has the mens rea because they intended to do it to avoid some threatened or actual harm. Thus, some degree of culpability already attaches to the defendant for what was done.

In criminal law, the defendant's motive for breaking the law is generally irrelevant unless a defendant is raising an affirmative defense allowed for by law. (Duress may or may not be allowed as an affirmative defense for some particular charge -- in particular, it is generally forbidden for murder, and many jurisdictions also forbid it for sexual assault. Malum in se offences, generally, are less likely to recognize duress as a defense than malum prohibitum offences.)

A successful affirmative defense means not that a criminal act was justified, but that the act was not criminal at all. But if no affirmative defense of duress is available, then the duress may be considered as justifying a lighter sentence, typically in proportion to the degree of duress. If the duress is extreme enough, for example, the defendant might be found guilty of murder but given a minimal, or even trivial, sentence.

In some rare cases, a successful argument of duress -- even when not an affirmative defense -- might result in the jury nullifying the charge by refusing to convict.

The basis of the defense is that the duress actually overwhelmed the defendant's will and would also have overwhelmed the will of a person of ordinary courage (a hybrid test requiring both subjective evidence of the accused's state of mind, and an objective confirmation that the failure to resist the threats was reasonable), thus rendering the entire behavior involuntary. Thus, the liability should be reduced or discharged, making the defense one of exculpation.

Trespass to land is a common law tort or crime that is committed when an individual or the object of an individual intentionally (or, in Australia, negligently) enters the land of another without a lawful excuse. Trespass to land is actionable per se. Thus, the party whose land is entered upon may sue even if no actual harm is done. In some jurisdictions, this rule may also apply to entry upon public land having restricted access. A court may order payment of damages or an injunction to remedy the tort.

By law, trespass for mesne profits is a suit against someone who has been ejected from property that did not belong to them. The suit is for recovery of damages the trespasser caused to the property and for any profits he or she may have made while in possession of that property.

For a trespass to be actionable, the tortfeasor must voluntarily go to a specific location but need not be aware that he entered the property of a particular person. If A forces B unwillingly onto C's land, C will not have action in trespass against B, because B's actions were involuntary. C may instead claim against A. Furthermore, if B is deceived by A as to the ownership or boundaries of C's land, A may be jointly liable with B for B's trespass.

In most jurisdictions, if a person were to accidentally enter onto private property, there would be no trespass, because the person did not intend any violation. However, in Australia, negligence may substitute the requirement for intent.

If a trespass is actionable and no action is taken within reasonable or prescribed time limits, the landowner may forever lose the right to seek a remedy, and may even forfeit certain property rights. Refer also to Adverse possession and Easement by prescription.

Trespass may also arise upon the easement of one person upon the land of another. For example, if A grants B a right to pass freely across A's land, then A would trespass upon B's easement by erecting a locked gate or otherwise blocking B's rightful access.

In some jurisdictions trespass while in possession of a firearm, which may include a low-power air weapon without ammunition, constitutes a more grave crime of armed trespass.

The maxim "cuius est solum, eius est usque ad coelum et ad infernos" (whoever owns the land owns it all the way to heaven and to hell) is said to apply, however that has been limited by practical considerations. For example, aerial trespass is limited to airspace which might be used (therefore aeroplanes cannot be sued). Landowners may not put-up structures to prevent this. The courts have been more lenient with putting up structures to prevent underground trespass. The Kentucky Court of Appeal in Edwards v Sims (1929) seems to affirm the maxim without qualification, whereas the New South Wales Supreme Court in Australia seemed more reluctant to do so in Di Napoli v New Beach Apartments (2004). There is therefore an asymmetry between aerial and underground trespass, which may be resolved by the fact the ground is almost always used (to support buildings and other structures) whereas airspace loses its practical use above the height of skyscrapers.

The estate tax in the United States is a federal tax on the transfer of the estate of a person who dies. The tax applies to property that is transferred by will or, if the person has no will, according to state laws of intestacy. Other transfers that are subject to the tax can include those made through a trust and the payment of certain life insurance benefits or financial accounts. The estate tax is part of the federal unified gift and estate tax in the United States. The other part of the system, the gift tax, applies to transfers of property during a person's life.

In addition to this federal estate tax, many states have enacted similar taxes. These taxes may be termed "inheritance taxes" to the extent the tax is payable by a person who inherits money or property of a person who has died, as opposed to an estate tax, which is a levy on the estate (money and property) of a person who has died.

The estate tax is often the subject of political debate, and opponents call it the "death tax." Some supporters of the tax have called it the "Paris Hilton tax."

If an asset is left to a spouse or a federally recognized charity, the tax usually does not apply. In addition, a maximum amount, varying year by year, can be given by an individual, before and/or upon their death, without incurring federal gift or estate taxes: $5,340,000 for estates of persons dying in 2014 and 2015, $5,450,000 (effectively $10.90 million per married couple, assuming the deceased spouse did not leave assets to the surviving spouse) for estates of persons dying in 2016. Because of these exemptions, it is estimated that only the largest 0.2% of estates in the U.S. will pay the tax. For 2017, the exemption increased to $5.49 million. In 2018, the exemption doubled to $11.18 million per taxpayer due to the Tax Cuts and Jobs Act of 2017. As a result, only about 2,000 estates per year in the US are currently liable for federal estate tax.

Federal estate tax.

The federal estate tax is imposed "on the transfer of the taxable estate of every decedent who is a citizen or resident of the United States."

Federal estate taxes give very wealthy families incentives to transfer resources directly to distant generations in order to avoid taxes on successive rounds of transfers. Until recently such transfers were impeded by the rule against perpetuities, which prevented transfers to most potential not-yet-born beneficiaries. Many American states have repealed the rule against perpetuities, raising concerns that the combination of tax incentives and new legal rights encourages the devotion of vast wealth to perpetual trusts designed to benefit distant generations, avoid taxes, and maintain a degree of control over the financial affairs of descendants in perpetuity.

One of the major concerns that motivate estate planning is the potential burden of federal taxes, which apply both to gifts during lifetime and to transfers at death. In practice, only a small fraction of U.S. estates is taxable, reflecting that exemption levels are high and transfers to surviving spouses are entirely excluded from taxable estates; but those estates that are subject to federal taxation typically face high rates. Taxpayers commonly arrange their affairs to soften the impact of federal taxation.

The starting point in the calculation is the "gross estate." Certain deductions from the "gross estate" are allowed to arrive at the "taxable estate."

Adverse possession, sometimes colloquially described as "squatter's rights", is a legal principle under which a person who does not have legal title to a piece of property — usually land (real property) — acquires legal ownership based on continuous possession or occupation of the property without the permission of its legal owner.

In general, a property owner has the right to recover possession of their property from unauthorized possessors through legal action such as ejectment. However, in the English common law tradition, courts have long ruled that when someone occupies a piece of property without permission and the property's owner does not exercise their right to recover their property for a significant period of time, not only is the original owner prevented from exercising their right to exclude, but an entirely new title to the property "springs up" in the adverse possessor. In effect, the adverse possessor becomes the property's new owner. Over time, legislatures have created statutes of limitations that specify the length of time that owners have to recover possession of their property from adverse possessors. In the United States, for example, these time limits vary widely between individual states, ranging from as low as three years to as long as 40 years.

Although the elements of an adverse possession action are different in every jurisdiction, a person claiming adverse possession is usually required to prove non-permissive use of the property that is actual, open and notorious, exclusive, adverse and continuous for the statutory period.

Personal property, traditionally known as 'chattel', may also be adversely possessed, but owing to the differences in the nature of real and chattel property, the rules governing such claims are rather more stringent, and favor the legal owner rather than the adverse possessor. Claims for adverse possession of chattel often involve works of art.

Foreseeability.

Legal Causation is usually expressed as a question of 'foreseeability'. An actor is liable for the foreseeable, but not the unforeseeable, consequences of his or her act. For example, it is foreseeable that if I shoot someone on a beach and they are immobilized, they may drown in a rising tide rather than from the trauma of the gunshot wound or from loss of blood. However, it is not (generally speaking) foreseeable that they will be struck by lightning and killed by that event.

This type of causal foreseeability is to be distinguished from foreseeability of extent or kind of injury, which is a question of remoteness of damage, not causation. For example, if I conduct welding work on a dock that lights an oil slick that destroys a ship a long way down the river, it would be hard to construe my negligence as anything other than causal of the ship's damage. There is no novus actus interveniens. However, I may not be held liable if that damage is not of a type foreseeable as arising from my negligence. That is a question of public policy, and not one of causation.

Example.

An example of how foreseeability does not apply to the extent of an injury is the eggshell skull rule. If Neal punches Matt in the jaw, it is foreseeable that Matt will suffer a bodily injury that he will need to go to the hospital for. However, if his jaw is very weak, and his jaw is dislocated by the punch, then the medical bills, which would have been about $5,000 for wiring his jaw shut had now become $100,000 for a full-blown jaw re-attachment. Neal would still be liable for the entire $100,000, even though $95,000 of those damages were not reasonably foreseeable.

Other relevant considerations.

Because causation in the law is a complex amalgam of fact and policy, other doctrines are also important, such as foreseeability and risk. Particularly in the United States, where the doctrine of 'proximate cause' effectively amalgamates the two-stage factual legal causation inquiry favored in the English system, one must always be alert to these considerations in assessing the postulated relationship between two events.

Capacity or more fully mental capacity covers day-to-day decisions, including: what to wear and what to buy, as well as, life-changing decisions, such as: whether to move into a care home or whether to have major surgery.

The UK's Mental Capacity Act 2005 or MCA sets out a two-stage test of capacity:

1. Is the person unable to make a particular decision?

2. Is the inability to make a decision caused by an impairment of, or disturbance in the functioning of, a person's mind or brain?

The MCA states an individual is unable to make their own decision, if they are unable to do at least one of four things:

1. Understand information given to them.

2. Retain that information long enough to be able to make the decision.

3. Weigh up the information available to make the decision.

4. Communicate their decision.

Discussion.

As an aspect of the social contract between a state and its citizens, the state adopts a role of protector to the weaker and more vulnerable members of society. In public policy terms, this is the policy of parens patriae. Similarly, the state has a direct social and economic interest in promoting trade, so it will define the forms of business enterprise that may operate within its territory, and lay down rules that will allow both the businesses and those that wish to contract with them a fair opportunity to gain value. This system worked well until social and commercial mobility increased. Now persons routinely trade and travel across state boundaries (both physically and electronically), so the need is to provide stability across state lines given that laws differ from one state to the next. Thus, once defined by the personal law, persons take their capacity with them like a passport whether or however they may travel. In this way, a person will not gain or lose capacity depending on the accident of the local laws, for example, if A does not have capacity to marry her cousin under her personal law (a rule of consanguinity), she cannot evade that law by travelling to a state that does permit such a marriage. In Saskatchewan Canada, an exception to this law allows married persons to become the common law spouse of others prior to divorcing the first spouse. This law is not honored amongst other Canadian provinces.

Trespass to goods.

Trespass to chattels, also known as trespass to goods or trespass to personal property, is defined as "an intentional interference with the possession of personal property...proximately cause injury". While originally a remedy for the asportation of personal property, the tort grew to incorporate any interference with the personal property of another. In some jurisdictions, such as the United Kingdom trespass to chattels has been codified to clearly define the scope of the remedy; in most jurisdictions, trespass to chattel remains a purely common law remedy, the scope of which varies by jurisdiction.

Generally, trespass to chattels possesses three elements:

1. Lack of consent. The interference with the property must be non-consensual. A claim does not lie if, in acquiring the property, the purchaser consents contractually to certain access by the seller. "Any use exceeding the consent" authorized by the contract, should it cause harm, gives rise to a cause for action.

2. Actual harm. The interference with the property must result in actual harm. The threshold for actual harm varies by jurisdiction. In California, for instance, an electronic message may constitute a trespass if the message interferes with the functioning of the computer hardware, but the plaintiff must prove that this interference caused actual hardware damage or actual impaired functioning.

3. Intentionality. The interference must be intentional. What constitutes intention varies by jurisdiction, however, the Restatement (Second) of Torts indicates that "intention is present when an act is done for the purpose of using or otherwise intermeddling with a chattel or with knowledge that such an intermeddling will, to a substantial certainty, result from the act", and continues: "t is not necessary that the actor should know or have reason to know that such intermeddling is a violation of the possessory rights of another".

Remedies for trespass to chattel include damages, liability for conversion, and injunction, depending on the nature of the interference.

Google LLC v Oracle America, Inc. was a legal case within the United States related to the nature of computer code and copyright law. The dispute centered on the use of parts of the Java programming language's application programming interfaces (APIs) and about 11,000 lines of source code, which are owned by Oracle (through subsidiary, Oracle America, Inc., originating from Sun Microsystems), within early versions of the Android operating system by Google. Google has since transitioned Android to a copyright-unburdened engine without the source code, and has admitted to using the APIs but claimed this was within fair use.

Oracle initiated the suit arguing that the APIs were copyrightable, seeking US$8.8 billion in damages from Google's sales and licensing of the earlier infringing versions of Android. While two District Court-level jury trials found in favor of Google, the Federal Circuit court reversed both decisions, asserting APIs are copyrightable and Google's use does not fall under fair use. Google successfully petitioned to the Supreme Court to hear the case in the 2019 term, focusing on the copyrightability of APIs and subsequent fair use; the case was delayed to the 2020 term due to the COVID-19 pandemic. In April 2021, the Supreme Court ruled in a 6–2 decision that Google's use of the Java APIs fell within the four factors of fair use, bypassing the question on the copyrightability of the APIs. The decision reversed the Federal Circuit ruling and remanded the case for further review.

The case has been of significant interest within the tech and software industries, as numerous computer programs and software libraries, particularly in open source, are developed by recreating the functionality of APIs from commercial or competing products to aid developers in interoperability between different systems or platforms.

Florida v Georgia, (2018), was a decision by the Supreme Court of the United States in an original jurisdiction case. It involves a long-running dispute over waters within the ACF River Basin, running from the north Georgia mountains through metro Atlanta to the Florida panhandle, which is managed by the United States Army Corps of Engineers. Waters in the area have been stressed by the population growth of Atlanta over previous decades. The immediate case stemmed from droughts in 2011 and 2012 that caused economic damage to Florida due to lower water flows from the ACF River Basin into the panhandle, impacting its seafood production; Florida sought relief to have more water allocated towards them from the ACF by placing a water allocation cap on Georgia. The Supreme Court assigned a special master to review Florida's complaint, but ultimately found in 2016 that Florida had not fully demonstrated the need for more allocation. Florida challenged this determination to the Supreme Court. On June 27, 2018, the Supreme Court ruled 5–4 that the special master had not properly considered Florida's argument and remanded the case to be reheard and reviewed.

Subsequently, the court replaced the special master, who later ruled against Florida in the dispute. Florida challenged the conclusions of the special master's report, but the Supreme Court overruled Florida's exceptions and unanimously dismissed the case in Florida v Georgia, (2021).

Unowned property refers to tangible, physical things which are capable of being reduced to being property owned by an individual but are not owned by anyone. Bona vacantia (Latin for "ownerless goods") is a legal concept associated with the unowned property, which exists in various jurisdictions, with a consequently varying application, but with origins mostly in English law.

Nearly every piece of land on the Earth is a property and has a maintainer (owner). The class of objects, "unowned things", are objects which are not yet property; either because it has been agreed by sovereign nations that no one can own them, or because no person, or other entity, has made a claim of ownership. The most common unowned things are asteroids. The UN's Outer Space Treaty does not address the issue of private ownership of natural objects in space. All asteroids remain unowned things until some person or entity makes a claim of property right to one of them.

In an experimental legal case of first impression, a lawsuit for a declaratory judgment was filed in a United States Federal Court to determine the lawful owner of Asteroid 433 Eros. 433 Eros was claimed as property by Gregory W Nemitz of Orbital Development. According to the homestead principle, Nemitz argued that he had the right to claim ownership of any celestial body that he made use of; he claimed he had designated Eros a spacecraft parking facility and wished to charge NASA a parking and storage fee of twenty cents per year for its NEAR Shoemaker spacecraft that is permanently stored there. Nemitz's case was dismissed due to lack of standing and an appeal denied.

A gift, in the law of property, is the voluntary and immediate transfer of property from one person (the donor or grantor) to another (the donee or grantee) without consideration. There are several types of gifts in property law, most notably inter vivos gifts which are made in the donor's lifetime and causa mortis (deathbed) gifts which are made in expectation of the donor's imminent death. Both types of gifts share three elements which must be met in order for the gift to be legally effective: donative intent (the intention of the donor to give the gift to the donee), the delivery of the gift to the donee, and the acceptance of the gift. In addition to those elements, causa mortis gifts require that the donor must die of the impending peril that he or she had contemplated when making the gift.

Causation is the "causal relationship between the defendant's conduct and end result". In other words, causation provides a means of connecting conduct with a resulting effect, typically an injury. In criminal law, it is defined as the actus reus (an action) from which the specific injury or other effect arose and is combined with mens rea (a state of mind) to comprise the elements of guilt. Causation only applies where a result has been achieved and therefore is immaterial with regard to inchoate offenses.

Background concepts.

Legal systems more or less try to uphold the notions of fairness and justice. If a state is going to penalize a person or require that person pay compensation to another for losses incurred, liability is imposed according to the idea that those who injure others should take responsibility for their actions. Although some parts of any legal system will have qualities of strict liability, in which the mens rea is immaterial to the result and subsequent liability of the actor, most look to establish liability by showing that the defendant was the cause of the particular injury or loss.

Even the youngest children quickly learn that, with varying degrees of probability, consequences flow from physical acts and omissions. The more predictable the outcome, the greater the likelihood that the actor caused the injury or loss intentionally. There are many ways in which the law might capture this simple rule of practical experience: that there is a natural flow to events, that a reasonable man in the same situation would have foreseen this consequence as likely to occur, that the loss flowed naturally from the breach of contractual duties or tortuous actions, etc. However it is phrased, the essence of the degree of fault attributed will lie in the fact that reasonable people try to avoid injuring others, so if harm was foreseeable, there should be liability to the extent that the extent of the harm actually resulting was foreseeable.

An implied-in-fact contract is a form of an implied contract formed by non-verbal conduct, rather than by explicit words. The United States Supreme Court has defined "an agreement 'implied in fact'" as "founded upon a meeting of minds, which, although not embodied in an express contract, is inferred, as a fact, from conduct of the parties showing, in the light of the surrounding circumstances, their tacit understanding."

Although the parties may not have exchanged words of agreement, their conduct may indicate that an agreement existed.

For example, if a patient goes to a doctor's appointment, the patient's actions indicate that they intend to receive treatment in exchange for paying reasonable/fair doctor's fees. Likewise, by seeing the patient, the doctor's actions indicate that they intend to treat the patient in exchange for payment of the bill. Therefore, it seems that a contract actually existed between the doctor and the patient, even though nobody spoke any words of agreement. (They both agreed to the same essential terms, and acted in accordance with that agreement. There was mutuality of consideration.) In such a case, the court will probably find that (as a matter of fact) the parties had an implied contract. If the patient refuses to pay after being examined, they will have breached the implied contract. Another example of an implied contract is the payment method known as a letter of credit.

Generally, an implied contract has the same legal force as an express contract. However, it may be more difficult to prove the existence and terms of an implied contract should a dispute arise. In some jurisdictions, contracts involving real estate may not be created on an implied-in-fact basis, requiring the transaction to be in writing.

Unilateral contracts are often the subject matter of these types of contracts where acceptance is being made by beginning a specified task.

A collateral contract is usually a single term contract, made in consideration of the party for whose benefit the contract operates agreeing to enter into the principal or main contract, which sets out additional terms relating to the same subject matter as the main contract. For example, a collateral contract is formed when one party pays the other party a certain sum for entry into another contract. A collateral contract may be between one of the parties and a third party.

It can also be epitomized as follows: a collateral contract is one that induces a person to enter into a separate "primary" contract. For example, if X agrees to buy goods from Y that will, accordingly, be manufactured by Z, and does so on the strength of Z's assurance as to the high quality of the goods, X and Z may be held to have made a collateral contract consisting of Z's promise of quality given in consideration of X's promise to enter into the main contract with Y.

Elements of a valid collateral contract.

A party to an existing contract may attempt to show that a collateral contract exists if their claim for a breach of contract fails because the statement they relied upon was not held to be a term of the main contract. It has been held that for this to be successful, the statement must have been promissory in nature. Remedies may be awarded for breach of a collateral contract.

Trespass is an area of criminal law or tort law broadly divided into three groups: trespass to the person, trespass to chattels, and trespass to land.

Trespass to the person historically involved six separate trespasses: threats, assault, battery, wounding, mayhem (or maiming), and false imprisonment. Through the evolution of the common law in various jurisdictions, and the codification of common law torts, most jurisdictions now broadly recognize three trespasses to the person: assault, which is "any act of such a nature as to excite an apprehension of battery"; battery, "any intentional and unpermitted contact with the plaintiff's person or anything attached to it and practically identified with it"; and false imprisonment, the "unlaw obstruct or deprive of freedom from restraint of movement". One can retrieve wounded or expired game from neighboring properties and boundaries even if the neighboring landowner does not give permission as long as there are no weapons in possession while retrieving game causes injury". Trespass to chattel does not require a showing of damages. Simply the "intermeddling with or use of … the personal property" of another gives cause of action for trespass. Since CompuServe Incorporated v Cyber Promotions, Inc., various courts have applied the principles of trespass to chattel to resolve cases involving unsolicited bulk e-mail and unauthorized server usage.

Trespass to land is today the tort most commonly associated with the term trespass; it takes the form of "wrongful interference with one's possessory rights in  property". Generally, it is not necessary to prove harm to a possessor's legally protected interest; liability for unintentional trespass varies by jurisdiction. "in common law, every unauthorized entry upon the soil of another was a trespasser"; however, under the tort scheme established by the Restatement of Torts, liability for unintentional intrusions arises only under circumstances evincing negligence or where the intrusion involved a highly dangerous activity.

Trespass has also been treated as a common law offense in some countries.

Tax credits.

Corporations, like other businesses, may be eligible for various tax credits which reduce federal, state or local income tax. The largest of these by dollar volume is the federal foreign tax credit. This credit is allowed to all taxpayers for income taxes paid to foreign countries. The credit is limited to that part of federal income tax before other credits generated by foreign source taxable income. The credit is intended to mitigate taxation of the same income to the same taxpayer by two or more countries and has been a feature of the U.S. system since 1918. Other credits include credits for certain wage payments, credits for investments in certain types of assets including certain motor vehicles, credits for use of alternative fuels and off-highway vehicle use, natural resource related credits, and others. 

Tax deferral.

Deferral is one of the main features of the worldwide tax system that allows U.S. multinational companies to delay paying taxes on foreign profits. Under U.S. tax law, companies are not required to pay U.S. tax on their foreign subsidiaries’ profits for many years, even indefinitely until the earnings are returned to U.S. Therefore, it was one of the main reasons that U.S. corporations paid low taxes, even though the corporate tax rate in the U.S. was one of the highest rates (35%) in the world. Although, since January 1, 2018 the corporate tax rate has been changed to a flat 21%.

Deferral is beneficial for U.S. companies to raise the cost of capital relatively to their foreign-based competitors. Their foreign subsidiaries can reinvest their earnings without incurring additional tax that allows them to grow faster. It is also valuable to U.S. corporations with global operations, especially for corporations with income in low-tax countries. Some of the largest and most profitable U.S. corporations pay exceedingly low tax rates through their use of subsidiaries in so-called tax haven countries. Eighty-three of the United states’ 100 biggest public companies have subsidiaries in countries that are listed as tax havens or financial privacy jurisdictions, according to the Government Accountability Office.

However, tax deferral encourages U.S. companies to make job-creating investments offshore even if similar investments in the United States can be more profitable, absent tax considerations. Furthermore, companies try to use accounting techniques to record profits offshore by any way, even if they keep actual investment and jobs in the United States. This explains why U.S. corporations report their largest profits in low-tax countries like the Netherlands, Luxembourg, and Bermuda, though clearly that is not where most real economic activity occurs.

Personal property is property that is movable. In common law systems, personal property may also be called chattels or personalty. In civil law systems, personal property is often called movable property or movables – any property that can be moved from one location to another.

Personal property can be understood in comparison to real estate, immovable property or real property (such as land and buildings).

Movable property on land (larger livestock, for example) was not automatically sold with the land, it was "personal" to the owner and moved with the owner.

The word cattle is the Old Norman variant of Old French chatel, chattel (derived from Latin capitalis, “of the head”), which was once synonymous with general movable personal property.

Classifications.

Personal property may be classified in a variety of ways.

Intangible.

Intangible personal property or "intangibles" refers to personal property that cannot actually be moved, touched or felt, but instead represents something of value such as negotiable instruments, securities, service (economics), and intangible assets including chose in action.

Tangible.

Tangible personal property refers to any type of property that can generally be moved (for example, it is not attached to real property or land), touched, or felt. These generally include items such as furniture, clothing, jewelry, art, writings, or household goods. In some cases, there can be formal title documents that show the ownership and transfer rights of that property after a person's death (for example, motor vehicles, boats, etcetera) In many cases, however, tangible personal property will not be "titled" in an owner's name and is presumed to be whatever property he or she was in possession of at the time of his or her death.

Mens rea (Law Latin for "guilty mind") is the mental element of a person's intention to commit a crime; or knowledge that one's action or lack of action would cause a crime to be committed. It is a necessary element of many crimes.

The standard common law test of criminal liability is expressed in the Latin phrase actus reus non facit reum nisi mens sit rea, for example, "the act is not culpable unless the mind is guilty". As a general rule, someone who acted without mental fault is not liable in criminal law. Exceptions are known as strict liability crimes. Moreover, when a person intends a harm, but because of bad aim or other cause, the intent is transferred from an intended victim to an unintended victim, the case is considered to be a matter of transferred intent.:

In civil law, it is usually not necessary to prove a subjective mental element to establish liability for breach of contract or tort, for example. But if a tort is intentionally committed or a contract is intentionally breached, such intent may increase the scope of liability and the damages payable to the plaintiff.

In some jurisdictions, the terms mens rea and actus reus have been replaced by alternative terminology.

Levels of mens rea.

Under the traditional common law, the guilt or innocence of a person relied upon whether he had committed the crime (actus reus), and whether he intended to commit the crime (mens rea). However, many modern penal codes have created levels of mens rea called modes of culpability, which depend on the surrounding elements of the crime: the conduct, the circumstances, and the result, or what the Model Penal Code calls CAR (conduct, attendant circumstances, result). The definition of a crime is thus constructed using only these elements rather than the colorful language of mens rea:

Murder is the unlawful killing of a human being with malice aforethought.

— 18 U.S.C. § 1111 (traditional common law).

A person commits an offense if he: (1) intentionally or knowingly causes the death of an individual.

— portion of Texas Penal Code § 19·02 (modern offense element).

The traditional common law definitions and the modern definitions approach the crime from different angles.

In the common law approach, the definition includes:

1. actus reus: unlawful killing of a human being.

2. mens rea: malice aforethought.

Modern criminal law approaches the analysis somewhat differently. Using a framework from the American Law Institute's Model Penal Code, homicide is a "results" offense in that it forbids any "purposeful" or "knowing" conduct that causes, and therefore results in the death of another human being. "Purposeful" in this sense means the actor possessed a conscious purpose or objective that the result (for example, the death of another human being) be achieved. "Knowing" means that the actor was aware or practically certain that a death would result but had no purpose or desire that it occur. Many states still adhere to older terminology, relying on the terms "intentional" to cover both types of mens rea: "purposeful" and "knowing."

Thus, the actus reus and mens rea of homicide in a modern criminal statute can be considered as follows:

1. actus reus: any conduct resulting in the death of another individual.

2. mens rea: purposeful intent or knowledge that the conduct would result in the death.

In the modern approach, attendant circumstances sometimes replace traditional concepts of mens rea, indicating the level of culpability as well as other circumstances. For example, the crime of theft of government property would include as an attendant circumstance that the property belong to the government, instead of requiring that the accused have actual awareness that the property belongs to the government 

Consideration is a concept of English common law and is a necessity for simple contracts but not for special contracts (contracts by deed). The concept has been adopted by other common law jurisdictions.

The court in Currie v Misa declared consideration to be a “Right, Interest, Profit, Benefit, or Forbearance, Detriment, Loss, Responsibility”. Thus, consideration is a promise of something of value given by a promisor in exchange for something of value given by a promisee; and typically the thing of value is goods, money, or an act. Forbearance to act, such as an adult promising to refrain from smoking, is enforceable only if one is thereby surrendering a legal right.

Consideration may be thought of as the concept of value offered and accepted by people or organizations entering into contracts. Anything of value promised by one party to the other when making a contract can be treated as "consideration": for example, if A signs a contract to buy a car from B for $5,000, A's consideration is the $5,000, and B's consideration is the car.

Additionally, if A signs a contract with B such that A will paint B's house for $500, A's consideration is the service of painting B's house, and B's consideration is $500 paid to A. Further if A signs a contract with B such that A will not repaint his own house in any other color than white, and B will pay A $500 per year to keep this deal up, there is also a consideration. Although A did not promise to affirmatively do anything, A did promise not to do something that he was allowed to do, and so A did pass consideration. A's consideration to B is the forbearance in painting his own house in a color other than white, and B's consideration to A is $500 per year. Conversely, if A signs a contract to buy a car from B for $0, B's consideration is still the car, but A is giving no consideration, and so there is no valid contract. However, if B still gives the title of the car to A, then B cannot take the car back, since, while it may not be a valid contract, it is a valid gift.

In common law it is a prerequisite that both parties offer consideration before a contract can be thought of as binding. The doctrine of consideration is irrelevant in many jurisdictions, although contemporary commercial litigant relations have held that the relationship between a promise and a deed is a reflection of the nature of contractual considerations. If there is no element of consideration found, there is thus no contract formed.

However, even if a court decides there is no contract, there might be a possible recovery under the doctrines of quantum meruit (sometimes referred to as a quasi-contract) or promissory estoppel.

Transferred intent (or transferred mens rea, or transferred malice, in English law) is a legal doctrine that holds that, when the intention to harm one individual inadvertently causes a second person to be hurt instead, the perpetrator is still held responsible. To be held legally responsible, a court typically must demonstrate that the perpetrator had criminal intent, that is, that they knew or should have known that another would be harmed by their actions and wanted this harm to occur. For example, if a murderer intends to kill John, but accidentally kills George instead, the intent is transferred from John to George, and the killer is held to have had criminal intent.

Transferred intent also applies to tort law. In tort law, there are generally five areas in which transferred intent is applicable: battery, assault, false imprisonment, trespass to land, and trespass to chattels. Generally, any intent to cause any one of these five torts which results in the completion of any of the five tortious acts will be considered an intentional act, even if the actual target of the tort is one other than the intended target of the original tort.

Corporate tax is imposed in the United States at the federal, most state, and some local levels on the income of entities treated for tax purposes as corporations. Since January 1, 2018, the nominal federal corporate tax rate in the United States of America is a flat 21% due to the passage of the Tax Cuts and Jobs Act of 2017. State and local taxes and rules vary by jurisdiction, though many are based on federal concepts and definitions. Taxable income may differ from book income both as to timing of income and tax deductions and as to what is taxable. The corporate Alternative Minimum Tax was also eliminated by the 2017 reform, but some states have alternative taxes. Like individuals, corporations must file tax returns every year. They must make quarterly estimated tax payments. Groups of corporations controlled by the same owners may file a consolidated return.

Some corporate transactions are not taxable. These include most formations and some types of mergers, acquisitions, and liquidations. Shareholders of a corporation are taxed on dividends distributed by the corporation. Corporations may be subject to foreign income taxes and may be granted a foreign tax credit for such taxes. Shareholders of most corporations are not taxed directly on corporate income but must pay tax on dividends paid by the corporation. However, shareholders of S corporations and mutual funds are taxed currently on corporate income, and do not pay tax on dividends.

In 2021 President Biden proposed that Congress raise the corporate rate from 21% to 28%.

In English common law, real property, real estate, realty, or immovable property is land which is the property of some person and all structures (also called improvements or fixtures) integrated with or affixed to the land, including crops, buildings, machinery, wells, dams, ponds, mines, canals, and roads, among other things. The term is historic, arising from the now-discontinued form of action, which distinguished between real property disputes and personal property disputes. Personal property was, and continues to be, all property that is not real property.

In countries with personal ownership of real property, civil law protects the status of real property in real-estate markets, where estate agents work in the market of buying and selling real estate. Scottish civil law calls real property "heritable property", and in French-based law, it is called immobilier ("immovable property").

Historical background.

The word "real" derives from Latin res ("thing"), which was used in Middle English to mean "relating to things, especially real property".

In common law, real property was a property that could be protected by some form of real action, in contrast to personal property, where a plaintiff would have to resort to another form of action. As a result of this formalist approach, some things the common law deems to be land would not be classified as such by most modern legal systems: for example, an advowson (the right to nominate a priest) was real property. By contrast, the rights of a leaseholder originate in personal actions and so the common law originally treated a leasehold as part of personal property.

The law now broadly distinguishes between real property (land and anything affixed to it) and personal property (everything else, e.g., clothing, furniture, money). The conceptual difference was between immovable property, which would transfer title along with the land, and movable property, which a person would retain title to.

In modern legal systems derived from English common law, classification of property as real or personal may vary somewhat according to jurisdiction or, even within jurisdictions, according to purpose, as in defining whether and how the property may be taxed.

Bethell (1998) contains much information on the historical evolution of real property and property rights.

Actus reus, sometimes called the external element or the objective element of a crime, is the Latin term for the "guilty act" which, when proved beyond a reasonable doubt in combination with the mens rea, "guilty mind", produces criminal liability in the common law−based criminal law jurisdictions of England, Canada, and the United States of America. In the United States, Some crimes also require proof of attendant circumstances and-or proof of a required result directly caused by the actus reus.

Definitions.

The terms actus reus and mens rea developed in English law are derived from the principle stated by Edward Coke, namely, actus non facit reum nisi mens sit rea, which means: "an act does not make a person guilty unless (their) mind is also guilty"; hence, the general test of guilt is one that requires proof of fault, culpability or blameworthiness both in thought and action.

In order for an actus reus to be committed there has to have been an act. Various common law define act differently but generally, an act is a "bodily movement whether voluntary or involuntary." In Robinson v California (1962), the U.S. Supreme Court ruled that a California law making it illegal to be a drug addict was unconstitutional because the mere status of being a drug addict was not an act and thus not criminal. Commentator Dennis Baker asserts: "Although lawyers find the expression actus reus convenient, it is misleading in one respect. It means not just the criminal act but all the external elements of an offence. Ordinarily, there is a criminal act, which is what makes the term actus reus generally acceptable. But there are crimes without an act, and therefore without an actus reus in the obvious meaning of that term. The expression 'conduct' is more satisfactory, because wider; it covers not only an act but an omission, and (by a stretch) a bodily position. The conduct must sometimes take place in legally relevant circumstances. The relevant circumstances might include consent in the case of rape. The act of human sexual intercourse becomes a wrongful act if it is committed in circumstances where one party does not consent and/or one or more parties concerned are below the age of consent. Other crimes require the act to produce a legally forbidden consequence. Such crimes are called result crimes. ... All that can truly be said, without exception, is that a crime requires some external state of affairs that can be categorized as criminal. What goes on inside a person's head is never enough in itself to constitute a crime, even though it might be proven by a confession that is fully believed to be genuine."

An act can consist of commission, omission or possession.

In the law of contracts, the mirror image rule, also referred to as an unequivocal and absolute acceptance requirement, states that an offer must be accepted exactly with no modifications. The offeror is the master of their own offer. An attempt to accept the offer on different terms instead creates a counter-offer, and this constitutes a rejection of the original offer.

United States.

In the United States, this rule still exists at common law. However, the Uniform Commercial Code ("UCC") dispenses with it in § 2-207. (but it can also be argued that § 2-207(1) enforces the mirror image rule) Therefore, its applicability depends upon what law governs. Most states have adopted the UCC, which governs transactions in goods. Contracts for services or land, for example, would not be governed by the UCC. The 2nd restatement of contracts also provides that when parties have not agreed to an essential term, "a term which is reasonable in the circumstances is supplied by the court." However, it may not be possible for a reasonable term to be supplied by the court.

England.

The English common law established the concepts of consensus ad idem, offer, acceptance and counter-offer. The leading case on counter-offer is Hyde v Wrench . The phrase "Mirror-Image Rule" is rarely (if at all) used by English lawyers; but the concept remains valid, as in Gibson v Manchester City Council , and Butler Machine Tool v Excello.

An invitation to treat (or invitation to bargain in the United States) is a concept within contract law which comes from the Latin phrase invitatio ad offerendum, meaning "inviting an offer". According to Professor Andrew Burrows, an invitation to treat is:

"...an expression of willingness to negotiate. A person making an invitation to treat does not intend to be bound as soon as it is accepted by the person to whom the statement is addressed."

A contract is a legally binding voluntary agreement formed when one person makes an offer, and the other accepts it. There may be some preliminary discussion before an offer is formally made. Such pre-contractual representations are known variously as “invitations to treat”, “requests for information” or “statements of intention”.

True offers may be accepted to form a contract, whereas representations such as invitations to treat may not. However, although an invitation to treat cannot be accepted it should not be ignored, for it may nevertheless affect the offer. For example, where an offer is made in response to an invitation to treat, the offer may incorporate the terms of the invitation to treat (unless the offer expressly incorporates different terms). If, as in the Boots case (described below) the offer is made by an action without any negotiations—such as presenting goods to a cashier—the offer will be presumed to be on the terms of the invitation to treat.

Intentional infliction of emotional distress (IIED; sometimes called the tort of outrage) is a common law tort that allows individuals to recover for severe emotional distress caused by another individual who intentionally or recklessly inflicted emotional distress by behaving in an "extreme and outrageous" way. Some courts and commentators have substituted mental for emotional, but the tort is the same.

Rationale for classification.

IIED was created in tort law to address a problem that would arise when applying the common law form of assault. The common law tort of assault did not allow for liability when a threat of battery was not imminent. A common case would be a future threat of harm that would not constitute common law assault but would nevertheless cause emotional harm to the recipient. IIED was created to guard against this kind of emotional abuse, thereby allowing a victim of emotional distress to receive compensation in situations where he or she would otherwise be barred from compensation under the common law form.

According to the first doctrine articulated by common law courts, a plaintiff could not recover for physical injury from fright alone absent a physical impact from an external source ("shock without impact"), even if the fright was proven to have resulted from a defendant's negligence, with the case on point referring to the negligent operation of a railroad. Even with intentional conduct, absent material damage, claims for emotional harm were similarly barred. "Mental pain or anxiety, the law cannot value, and does not pretend to redress, when the unlawful act causes that alone. Though where a material damage occurs, and is connected with it, it is impossible a jury, in estimating it, should altogether overlook the feelings of the party interested." Courts had been reluctant to accept a tort for emotional harm for fear of opening a "wide door" to frivolous claims.

A change first occurred in the Irish courts which repudiated the English railroad decision and recognized liability for "nervous shock" in the Byrne (1884) and Bell (1890) cases  In England, the idea that physical/mental shock without impact from an external source should be a bar to recovery was first questioned at the Queen's Bench in Pugh v London etcetera, Railroad Co. In the following year, the Queen's Bench formally recognized the tort, for the first time, in the case of Wilkinson v Downton, although it was referred to as "intentional infliction of mental shock". Wilkinson has been subsequently approved by both the Court of Appeal (Janvier v Sweeney) and House of Lords (Wainwright v Home Office). Citing Pugh and the Irish courts as precedent, the Wilkinson court noted the willful nature of the act as a direct cause of the harm.

In the United States of America, individuals and corporations pay U.S. federal income tax on the net total of all their capital gains. The tax rate depends on both the investor's tax bracket and the amount of time the investment was held. Short-term capital gains are taxed at the investor's ordinary income tax rate and are defined as investments held for a year or less before being sold. Long-term capital gains, on dispositions of assets held for more than one year, are taxed at a lower rate.

Current law.

The United States taxes short-term capital gains at the same rate as it taxes ordinary income.

Long-term capital gains are taxed at lower rates shown in the table below. (Qualified dividends receive the same preference.)

 unrecaptured Section 1250 gain — the portion of gains on depreciable real estate (structures used for business purposes) that has been or could have been claimed as depreciation — is capped at 25%.

The income amounts ("tax brackets") were reset by the Tax Cuts and Jobs Act of 2017 for the 2018 tax year to equal the amount that would have been due under prior law. They will be adjusted each year based on the Chained CPI measure of inflation. These income amounts are after deductions: There is another bracket of income below that shown as $0 in the table, on which no tax is due. For 2018, this amount is at least the standard deduction, $12,000 for an individual return and $24,000 for a joint return, or more if the taxpayer has over that amount in itemized deductions.

Additional taxes.

There may be taxes in addition to the tax rates shown in the above table.

Taxpayers earning income above certain thresholds ($200,000 for singles and heads of household, $250,000 for married couples filing jointly and qualifying widowers with dependent children, and $125,000 for married couples filing separately) pay an additional 3.8% tax on all investment income. This tax is known as the net investment income tax. Therefore, the top federal tax rate on long-term capital gains is 23.8%.

State and local taxes often apply to capital gains. In a state whose tax is stated as a percentage of the federal tax liability, the percentage is easy to calculate. Some states structure their taxes differently. In this case, the treatment of long-term and short-term gains does not necessarily correspond to the federal treatment.

Capital gains do not push ordinary income into a higher income bracket. The Capital Gains and Qualified Dividends Worksheet in the Form 1040 instructions specifies a calculation that treats both long-term capital gains and qualified dividends as though they were the last income received, then applies the preferential tax rate as shown in the above table. Conversely, however, this means an increase in ordinary income will withdraw the 0% and 15% brackets for capital gains taxes.

Property law in the United States is the area of law that governs the various forms of ownership in real property (land and buildings) and personal property, including intangible property such as intellectual property. Property refers to legally protected claims to resources, such as land and personal property. Property can be exchanged through contract law, and if property is violated, one could sue under tort law to protect it.

United States property law is primarily an area for state law, although there are also federal laws (for example, on patents and copyright) and some local laws involved (on areas such as zoning and tenancy). Property law in the states generally originate from the common law and have been modified by statutes. The Restatements on Property gives an overview of certain areas of property law in the United States.

Theory of property rights.

Definition of property rights.

There are two main views on the right to property in the United States, the traditional view and the bundle of rights view. The traditionalists believe that there is a core, inherent meaning in the concept of property, while the bundle of rights view states that the property owner only has a bundle of permissible uses over the property. The two views exist on a spectrum and the difference may be a matter of focus and emphasis.

William Blackstone, in his Commentaries on the Laws of England, wrote that the essential core of property is the right to exclude. That is, the owner of property must be able to exclude others from the thing in question, even though the right to exclude is subject to limitations. By implication, the owner can use the thing, unless another restriction, such as zoning law, prevents it. Other traditionalists argue that three main rights define property: the right to exclusion, use and transfer.

An alternative view of property, favored by legal realists, is that property simply denotes a bundle of rights defined by law and social policy. Which rights are included in the bundle known as property rights, and which bundles are preferred to which others, is simply a matter of policy. Therefore, a government can prevent the building of a factory on a piece of law, through zoning law or criminal law, without damaging the concept of property. The "bundle of rights" view was prominent in academia in the 20th century and remains influential today in American law.

Responsibility for criminal law and criminal justice in the United States is shared between the states and the federal government.

Sources of law.

The federal government and all the states rely on the following.

Common law.

Common law is law developed by judges through legal opinions, as opposed to statutes adopted through the legislative process or regulations issued by the executive branch. A common law crime is thus a crime which was originally defined by judges.

Common law crimes no longer exist at the federal level, because of the U.S. Supreme Court's decision in United States v Hudson and Goodwin, (1812). The validity of common law crimes varies at the state level. Although most states have abolished common law crimes, some have enacted "reception" statutes recognizing common law crimes when no similar statutory crime exists.

Statutes.

All 50 states have their own penal codes. Therefore, for any particular crime somewhere, it would be necessary to look it up in that jurisdiction. However, statutes derive from the common law. For example, if a state's murder statute does not define "human being," that state's courts will rely on the common-law definition.

State vs. federal.

The states, since they possess the police power, have the most general power to pass criminal laws in the United States. The federal government, since it can only exercise those powers granted to it by the Constitution, can only pass criminal laws which are related to the powers granted to Congress. For example, drug crimes, which comprise a large percentage of federal criminal cases, are subject to federal control because drugs are a commodity for which there is an interstate market, thus making controlled substances subject to regulation by Congress in the Controlled Substances Act which was passed under the authority of the Commerce Clause. Gonzales v Raich affirmed Congress's power to regulate drug possession under the Controlled Substances Act under the powers granted to it by the Commerce Clause.

Model Penal Code.

The Model Penal Code ("MPC") was created by the American Law Institute ("ALI") in 1962. In other areas of law, the ALI created Restatements of Law, usually referred to just as Restatements. For example, there is a Restatement of Contracts and a Restatement of Torts. The MPC is their equivalent for criminal law.

Many states have wholly or largely adopted the MPC. Others have implemented it in part, and still others have not adopted any portion of it. However, even in jurisdictions where it has not been adopted, the MPC is often cited as persuasive authority in the same way that Restatements are in other areas of law.

The posting rule (or mailbox rule in the United States, also known as the "postal rule" or "deposited acceptance rule") is an exception to the general rule of contract law in common law countries that acceptance of an offer takes place when communicated. Under the posting rule, that acceptance takes effect when a letter is posted (that is, dropped in a post box or handed to a postal worker). In plain English, the "meeting of the minds" necessary to contract formation occurs at the exact moment word of acceptance is sent via post by the person accepting it, rather than when that acceptance is received by the person who offered the contract.

The rules of contracts by post (postal rules) include the following:

1.  An offer made by post/letter is not effective until received by the offeree.

2.  Acceptance is effective as soon as it is posted.

3.  For revocation to be effective, it must be received by the offeree before they post their letter of acceptance.

One rationale given for the rule is that the offeror nominates the post office as his or her implied agent, and thus receipt of the acceptance by the post office is regarded as receipt by the offeror. The main effect of the posting rule is that the risk of acceptance being delivered late or lost in the post is placed upon the offeror. If the offeror is reluctant to accept this risk, he can always expressly require actual receipt as a condition before being legally bound by his offer.

False imprisonment or unlawful imprisonment occurs when a person intentionally restricts another person’s movement within any area without legal authority, justification, or the restrained person's permission. Actual physical restraint is not necessary for false imprisonment to occur. A false imprisonment claim may be made based upon private acts, or upon wrongful governmental detention. For detention by the police, proof of false imprisonment provides a basis to obtain a writ of habeas corpus.

Under common law, false imprisonment is both a crime and a tort.

Imprisonment.

Within the context of false imprisonment, an imprisonment occurs when a person is restrained from moving from a location or bounded area, as a result of a wrongful intentional act, such as the use of force, threat, coercion, or abuse of authority.

Detention that is not false imprisonment.

Even when a person is involuntarily detained, not all acts of detention amount to false imprisonment. The law may privilege a person to detain somebody else against their will. A legally authorized detention does not constitute false imprisonment. For example, if a parent or legal guardian of a child denies the child's request to leave their house, and prevents them from doing so, this would not ordinarily constitute false imprisonment. False imprisonment requires an intentional act, and an accidental detention will not support a claim of false imprisonment.

Complete restraint.

'Imprisonment is, as I apprehend, a total restraint of the liberty of the person, for however, short a time, and not a partial obstruction of his will, whatever inconvenience it may bring on him.' There must be complete restraint, therefore, if there are alternative routes that can be taken this is not false imprisonment. Such as in Bird v Jones  where the claimant wanted to walk over Hammersmith bridge but the defendant had cordoned off the public footpath, however, this did not constitute false imprisonment because, through using a longer route, the claimant could have still reached their destination.

Therefore, if there is a means of escape, this is not false imprisonment. There must be no reasonable means of escape and you may be compensated for any damages caused in order for you to escape reasonably. However, if you have not taken a reasonable route of escape/reasonable action you will not be awarded damages.

The claimant does not need to be aware they are being imprisoned.

It is still false imprisonment even where the claimant does not know at the time. So secretly locking someone in a room is false imprisonment. It may also be false imprisonment where a person is rendered unconscious, for example, by being punched (also a battery), or when their drink is spiked by drugs (also willful harm or negligence), because their freedom of movement is thereby restricted. For example, in the case of Meering v Grahame-White Aviation  the claimant was told to stay in an office because property was going missing and if they tried to leave the office they would have been stopped. This was held to be a false imprisonment even though the claimant did not know they were being imprisoned.

In the United States of America, individuals and corporations pay U.S. federal income tax on the net total of all their capital gains. The tax rate depends on both the investor's tax bracket and the amount of time the investment was held. Short-term capital gains are taxed at the investor's ordinary income tax rate and are defined as investments held for a year or less before being sold. Long-term capital gains, on dispositions of assets held for more than one year, are taxed at a lower rate.

Current law.

The United States taxes short-term capital gains at the same rate as it taxes ordinary income.

Long-term capital gains are taxed at lower rates shown in the table below. (Qualified dividends receive the same preference.)

 unrecaptured Section 1250 gain — the portion of gains on depreciable real estate (structures used for business purposes) that has been or could have been claimed as depreciation — is capped at 25%.

The income amounts ("tax brackets") were reset by the Tax Cuts and Jobs Act of 2017 for the 2018 tax year to equal the amount that would have been due under prior law. They will be adjusted each year based on the Chained CPI measure of inflation. These income amounts are after deductions: There is another bracket of income below that shown as $0 in the table, on which no tax is due. For 2018, this amount is at least the standard deduction, $12,000 for an individual return and $24,000 for a joint return, or more if the taxpayer has over that amount in itemized deductions.

Additional taxes.

There may be taxes in addition to the tax rates shown in the above table.

Taxpayers earning income above certain thresholds ($200,000 for singles and heads of household, $250,000 for married couples filing jointly and qualifying widowers with dependent children, and $125,000 for married couples filing separately) pay an additional 3.8% tax on all investment income. This tax is known as the net investment income tax. Therefore, the top federal tax rate on long-term capital gains is 23.8%.

State and local taxes often apply to capital gains. In a state whose tax is stated as a percentage of the federal tax liability, the percentage is easy to calculate. Some states structure their taxes differently. In this case, the treatment of long-term and short-term gains does not necessarily correspond to the federal treatment.

Capital gains do not push ordinary income into a higher income bracket. The Capital Gains and Qualified Dividends Worksheet in the Form 1040 instructions specifies a calculation that treats both long-term capital gains and qualified dividends as though they were the last income received, then applies the preferential tax rate as shown in the above table. Conversely, however, this means an increase in ordinary income will withdraw the 0% and 15% brackets for capital gains taxes.

Property law is the area of law that governs the various forms of ownership in real property (land) and personal property. Property refers to legally protected claims to resources, such as land and personal property, including intellectual property. Property can be exchanged through contract law, and if property is violated, one could sue under tort law to protect it.

The concept, idea or philosophy of property underlies all property law. In some jurisdictions, historically all property was owned by the monarch and it devolved through feudal land tenure or other feudal systems of loyalty and fealty.

Though the Napoleonic code was among the first government acts of modern times to introduce the notion of absolute ownership into statute, protection of personal property rights was present in medieval Islamic law and jurisprudence, and in more feudalist forms in the common law courts of medieval and early modern England.

Theory.

The word property, in everyday usage, refers to an object (or objects) owned by a person—a car, a book, or a cellphone—and the relationship the person has to it. In law, the concept acquires a more nuanced rendering. Factors to consider include the nature of the object, the relationship between the person and the object, the relationship between a number of people in relation to the object, and how the object is regarded within the prevailing political system. Most broadly and concisely, property in the legal sense refers to the rights of people in or over certain objects or things.

Non-legally recognized or documented property rights are known as informal property rights. These informal property rights are non-codified or documented but recognized among local residents to varying degrees.

Justifications and drawbacks of property rights.

In capitalist societies with market economies, much of property is owned privately by persons or associations and not the government. Five general justifications have been given on private property rights:

1. Private property is an efficient way to manage resources in a decentralized basis, allowing expertise and specialization to develop with regard to the property.

2. Private property is a powerful incentive for owners to put it to productive use because they stand to gain in the investment.

3. Private property allows exchanges and modifications.

4. Private property is an important source of individual autonomy, giving individuals independence and identity distinct from others.

5. Private property, being dispersed, allows individuals to exercise freedom, against others or against the government.

Arguments in favor of limiting private property rights have also been raised:

1. Private property can be used in a way that is harmful to others, such as a factory owner causing loud noises in nearby neighborhoods. In economics, this is known as a negative externality. Nuisance laws and government regulations (such as zoning) have been used to limit an owners' right to use the property in certain ways.

2. Property can lead to monopolies, giving the owner the power to unfairly extract advantages from others. Because of this, there are often laws on competition and antitrust.

3. Property can lead to the commodification of certain domains which people would prefer not to be commodified, such as social relations. There is debate in certain countries, for example, on whether organ sales or sex services should be legal.

4. Private property gives individuals power, which can exacerbate over time and lead to too much inequality within a society. The propensity for inequality is justification of wealth redistribution.

Criminal law is the body of law that relates to crime. It prescribes conduct perceived as threatening, harmful, or otherwise endangering to the property, health, safety, and moral welfare of people inclusive of one's self. Most criminal law is established by statute, which is to say that the laws are enacted by a legislature. Criminal law includes the punishment and rehabilitation of people who violate such laws.

Criminal law varies according to jurisdiction, and differs from civil law, where emphasis is more on dispute resolution and victim compensation, rather than on punishment or rehabilitation.

Criminal procedure is a formalized official activity that authenticates the fact of commission of a crime and authorizes punitive or rehabilitative treatment of the offender.

History.

The first civilizations generally did not distinguish between civil law and criminal law. The first written codes of law were designed by the Sumerians. Around 2100 thru 2050 BC Ur-Nammu, the Neo-Sumerian king of Ur, enacted written legal code whose text has been discovered: the Code of Ur-Nammu although an earlier code of Urukagina of Lagash ( 2380 thru 2360 BC ) is also known to have existed. Another important early code was the Code of Hammurabi, which formed the core of Babylonian law. Only fragments of the early criminal laws of Ancient Greece have survived, e.g. those of Solon and Draco.

In Roman law, Gaius's Commentaries on the Twelve Tables also conflated the civil and criminal aspects, treating theft (furtum) as a tort. Assault and violent robbery were analogized to trespass as to property. Breach of such laws created an obligation of law or vinculum juris discharged by payment of monetary compensation or damages. The criminal law of imperial Rome is collected in Books 47 thru 48 of the Digest. After the revival of Roman law in the 12th century, sixth-century Roman classifications and jurisprudence provided the foundations of the distinction between criminal and civil law in European law from then until the present time.

The first signs of the modern distinction between crimes and civil matters emerged during the Norman Invasion of England. The special notion of criminal penalty, at least concerning Europe, arose in Spanish Late Scholasticism (see Alfonso de Castro), when the theological notion of God's penalty (poena aeterna) that was inflicted solely for a guilty mind, became transfused into canon law first and, finally, to secular criminal law. The development of the state dispensing justice in a court clearly emerged in the eighteenth century when European countries began maintaining police services. From this point, criminal law formalized the mechanisms for enforcement, which allowed for its development as a discernible entity.

Offer and acceptance are generally recognized as essential requirements for the formation of a contract, and analysis of their operation is a traditional approach in contract law. The offer and acceptance formula, developed in the 19th century, identifies a moment of formation when the parties are of one mind. This classical approach to contract formation has been modified by developments in the law of estoppel, misleading conduct, misrepresentation, unjust enrichment, and power of acceptance.

Offer.

Treitel defines an offer as "an expression of willingness to contract on certain terms, made with the intention that it shall become binding as soon as it is accepted by the person to whom it is addressed", the "offeree". An offer is a statement of the terms on which the offeror is willing to be bound. It is the present contractual intent to be bound by a contract with definite and certain terms communicated to the offeree.

The expression of an offer may take different forms and which form is acceptable varies by jurisdiction. Offers may be presented in a letter, newspaper advertisement, fax, email verbally or even conduct, as long as it communicates the basis on which the offeror is prepared to contract.

Whether the two parties have reached agreement on the terms or whether a valid offer has been made is an issue which is determined by the applicable law. In certain jurisdictions, courts use criteria known as 'the objective test' which was explained in the leading English case of Smith v Hughes. In Smith v Hughes, the court emphasized that the important thing in determining whether there has been a valid offer is not the party's own (subjective) intentions, but how a reasonable person would view the situation. The objective test is largely superseded in the UK since the introduction of the Brussels Regime in combination with the Rome I Regulation.

An offer can only be the basis of a binding contract if it contains the key terms of the contract. For example, as a minimum requirement for sale of goods contracts, a valid offer must include at least the following four terms: Delivery date, price, terms of payment that includes the date of payment and detailed description of the item on offer including a fair description of the condition or type of service. Unless the minimum requirements are met, an offer of sale is not classified by the courts as a legal offer but is instead seen as an advertisement. Under Dutch law an advertisement is in most cases an invitation to make an offer, rather than an offer.

At common law, battery is a tort falling under the umbrella term 'Trespass to the person'. Entailing unlawful contact which is directed and intentional, or reckless (or, in Australia, negligently) and voluntarily bringing about a harmful or offensive contact with a person or to something closely associated with them, such as a bag or purse, without legal consent.

Unlike assault, in which the fear of imminent contact may support a civil claim, battery involves an actual contact. The contact can be by one person (the tortfeasor) of another (the victim), with or without a weapon, or the contact may be by an object brought about by the tortfeasor. For example, intentionally bringing a car into contact with another person, or the intentional striking of a person with a thrown rock, is a battery.

Unlike criminal law, which recognizes degrees of various crimes involving physical contact, there is but a single tort of battery. Lightly flicking a person's ear is battery, as is severely beating someone with a tire iron. Neither is there a separate tort for a battery of a sexual nature. However, a jury hearing a battery case is free to assess higher damages for a battery in which the contact was particularly offensive or harmful.

Since it is practically impossible to avoid physical contact with others during everyday activities, everyone is presumed to consent to a certain amount of physical contact with others, such as when one person unavoidably brushes or bumps against another in a crowded lift, passage, or stairway. However, physical contact may not be deemed consented to if the acts that cause harm are prohibited acts.

Contact required.

Battery is a form of trespass to the person and as such no actual damage (for example, injury) needs to be proved. Only proof of contact (with the appropriate level of intention or negligence) needs to be made. An attempt to commit a battery, but without making actual contact, may constitute a tort of assault. The tort of battery developed out of a general judicial respect of an individual's autonomy and right not to be interfered with.

Battery need not require body-to-body contact. Touching an object "intimately connected", to a person (such as an object he or she is holding) can also be a battery. Furthermore, a contract may constitute a battery even if there is a delay between the defendant's act and the contact to the plaintiff's injury. For example, where a person who digs a pit with the intent that another will fall into it later, or where a person who mixes something offensive in food that he knows another will eat, has committed a battery against that other when the other does in fact fall into the pit or eats the offensive matter.

The Executive: Powers committed to the President of the United States (Article II).

Article II, Section 1, vests the executive power in the President of the United States of America. Unlike the commitment of authority in Article I, which refers to Congress only specifically enumerated powers "herein granted" and such powers as may be necessary and proper to carry out the same, Article II is all-inclusive in its commitment of the executive power in a President of the United States of America.

Enumerated powers of the President Several important powers are expressly committed to the President under Article II, Section 2. These include:

Commander-in-chief of the armed forces.

Power to pardon offenses against the United States.

Power to make treaties (with consent of the Senate); and the

Power to appoint judges, ambassadors, and other officers of the United States (often requiring Senate consent).

The Presentment Clause (Article I, Section 7, cl. 2-3) grants the president the power to veto Congressional legislation and Congress the power to override a presidential veto with a supermajority. Under the clause, once a bill has been passed in identical form by both houses of Congress, with a two thirds majority in both houses, it becomes federal law.

First, the president can sign the bill into law. In this scenario there is Congressional agreement. Second, if not in agreement, the president can veto the legislation by sending the bill back to Congress, within ten days of reception, unsigned and with a written statement of his objections. Third, the president can choose not to act at all on the bill, which can have one of two effects, depending on the circumstances. If Congress is in session, the bill automatically becomes law, without the president's signature, only with a two thirds majority of both houses. If, however, Congress adjourns during that 10-day period, the bill fails to become law in a procedural device known as the "pocket veto". The bill becomes "mute".

The president approves or rejects a bill in its entirety; he is not permitted to veto specific provisions. In 1996, Congress passed, and President Bill Clinton signed, the Line Item Veto Act of 1996, which gave the president the power to veto individual items of budgeted expenditures in appropriations bills. The Supreme Court subsequently declared the line-item veto unconstitutional as a violation of the Presentment Clause in Clinton v City of New York, (1998). The Court construed the Constitution's silence on the subject of such unilateral presidential action as equivalent to "an express prohibition," agreeing with historical material that supported the conclusion that statutes may only be enacted "in accord with a single, finely wrought and exhaustively considered, procedure", and that a bill must be approved or rejected by the president in its entirety. The Court reasoned that a line-item veto "would authorize the President to create a different law--one whose text was not voted on by either House of Congress or presented to the President for signature," and therefore violates the federal legislative procedure prescribed in Article I, Section 7.

United States constitutional law is the body of law governing the interpretation and implementation of the United States Constitution. The subject mainly concerns the scope of power of the United States federal government as compared to the individual states and the fundamental rights of individuals. As the ultimate authority on matters of constitutional interpretation, the decisions of the Supreme Court of the United States make up a large portion of constitutional law.

Interpreting the Constitution and the authority of the Supreme Court.

The power of judicial review.

Early in its history, in Marbury v Madison, (1803) and Fletcher v Peck, (1810), the Supreme Court of the United States declared that the judicial power granted to it by Article III of the United States Constitution included the power of judicial review, to consider challenges to the constitutionality of a State or Federal law. According to this jurisprudence, when the Court measures a law against the Constitution and finds the law wanting, the Court is empowered and indeed obligated to strike down that law. In this role, for example, the Court has struck down state laws for failing to conform to the Contract Clause (see, e.g., Dartmouth College v Woodward) or the Equal Protection Clause (see, e.g., Brown v Board of Education), and it has invalidated federal laws for failing to arise under the Commerce Clause of the Constitution (see, for example, United States v Lopez).

Scope and effect.

The Supreme Court's interpretations of constitutional law are binding on the legislative and executive branches of the federal government, on the lower courts in the federal system, and on all state courts. This system of binding interpretations or precedents evolved from the common law system (called "stare decisis"), where courts are bound by their own prior decisions and by the decisions of higher courts. While neither English common law courts nor continental civil law courts generally had the power to declare legislation unconstitutional (only the power to change law), the United States Supreme Court has long been understood to have the power to declare federal or state legislation unconstitutional.

Formality.

Ordinarily, contracts do not have to be in writing to be enforceable. However, certain types of contracts do have to be reduced to writing to be enforceable, to prevent frauds and perjuries, hence the name statute of frauds, which also makes it not a misnomer (fraud need not be present to implicate the statute of frauds).

Typically, the following types of contracts implicate the statute of frauds:

Land, including leases over a year and easements.

Suretyships (promises to answer for the debts, defaults, or miscarriages of another).

Consideration of marriage (not to actually get married but to give a dowry, for example).

Goods over a certain amount of money (usually $500, as in the UCC).

Contracts that cannot be performed within one year.

For example, a two-year employment contract naturally cannot be performed within one year.

In many states’ lifetime contracts are not considered to fall within the Statute of Frauds reasoning that life can end at any time, certainly within one year from the time of execution. In other states, notably Illinois, contracts requiring performance for a lifetime are covered by the Statute.

The statute of frauds requires the signature of the party against whom enforcement is sought (the party to be sued for failure to perform). For example, Bob contracts with the Smith Company for two years of employment. The employer would need to sign the writing.

Moreover, the writing for purposes of satisfying the statute of frauds does not need to be the actual contract. It might be a letter, memorializing and formalizing an oral arrangement already made over the phone. Therefore, the signed writing does not need to contain all of the terms that the parties agreed to. At common law, only the essential terms were required in the signed writing. Under the UCC, the only term that must be present in the writing is the quantity. The writing also does not need to be one document, but if there are multiple documents, they must all obviously refer to the same transaction, and they all must be signed. The signature itself does not need to be a full name. Any mark made with the intent to authenticate the writing is satisfactory, such as initials or even such as an X by an illiterate party.

A contract that may otherwise be unenforceable under the statute of frauds may become enforceable under the doctrine of part performance. If the party seeking enforcement of the contract has partially or fulfilled its duties under the contract without objection from the other party, the performing party may be able to use its performance to hold the other party to the terms of the contract.

No writing is required when:

Goods have been received and accepted.

Payment has been made and accepted.

Goods are specially manufactured (there is no market for them); or,

under the UCC, the party against whom enforcement is being sought admits a certain quantity of goods.

The last exception applies up to the quantity admitted, which may include the entire contract. This reversed the rule at common law that permitted a defendant to testify that he indeed contracted with the plaintiff but refuses to perform because it is not in writing.

Contract law regulates the obligations established by agreement, whether express or implied, between private parties in the United States. The law of contracts varies from state to state; there is nationwide federal contract law in certain areas, such as contracts entered into pursuant to Federal Reclamation Law.

The law governing transactions involving the sale of goods has become highly standardized nationwide through widespread adoption of the Uniform Commercial Code. There remains significant diversity in the interpretation of other kinds of contracts, depending upon the extent to which a given state has codified its common law of contracts or adopted portions of the Restatement (Second) of Contracts.

Formation.

A contract is an agreement between two or more parties creating reciprocal obligations enforceable at law. The elements of a contract are mutual consent, offer and acceptance, consideration, and legal purpose.

Agreement.

Mutual consent, also known as ratification and meeting of the minds, is typically established through the process of offer and acceptance. However, contracts can also be implied in fact, as discussed below. At common law, the terms of a purported acceptance must be the "mirror image" of the terms of the offer. Any variation thereof constitutes a counteroffer.

An offer is a display of willingness by a promisor to be legally bound by terms they specify, made in a way that would lead a reasonable person in the promise’s position to understand that an acceptance is being sought and, if made, results in an enforceable contract. Ordinarily, an offeror is permitted to revoke their offer at any time prior to a valid acceptance. This is partially due to the maxim that an offeror is the "master of his offer."

In the case of options, the general rule stated above applies even when the offeror promises to hold the offer open for a certain period of time. For example, Alice says to Bob, "I'll sell you my watch for $10, and you can have a week to decide." Alice is free to revoke her offer during the week, as long as Bob has not accepted the offer.

However, if the offeree gives some separate consideration (discussed below) to keep the offer open for a certain period of time, the offeror is not permitted to revoke during that period. For example, Alice offers to sell Bob her watch for $10. Bob gives Alice $1 to keep the offer open for a week. Alice is not permitted to revoke during the week.

An intentional tort is a category of torts that describes a civil wrong resulting from an intentional act on the part of the tortfeasor (alleged wrongdoer). The term negligence, on the other hand, pertains to a tort that simply results from the failure of the tortfeasor to take sufficient care in fulfilling a duty owed, while strict liability torts refers to situations where a party is liable for injuries no matter what precautions were taken.

 Why intentional torts are different.

As a matter of public policy, damages available for intentional torts tend to be broader and more generous than for negligent torts. To preserve individual well-being and overall social welfare, society generally wishes to deter its members from intentionally attacking each other. For example, in the United States, it is easier to get punitive damages (damages above and beyond compensatory damages) if one can prove that the tort was intentional. Similarly, in most Australian jurisdictions, intentional torts are not included in civil liability legislation, thus excluding the threshold of injury and damages payouts from various legislated limitations and caps. But it is harder to prove intentional torts because as with many felony crimes, one must prove subjective elements involving the content of the defendant's mind, and defendants do not always express their harmful intent out loud or in writing.

In common law, assault is the tort of acting intentionally, that is with either general or specific intent, causing the reasonable apprehension of an immediate harmful or offensive contact. Assault requires intent, it is considered an intentional tort, as opposed to a tort of negligence. Actual ability to carry out the apprehended contact is not necessary. 'The conduct forbidden by this tort is an act that threatens violence.'

In Criminal Law an assault is defined as an attempt to commit battery, requiring the specific intent to cause physical injury.

Comparison to battery.

As distinguished from battery, assault does not need to involve the 'unwanted physical contact; but is the anticipation of such contact'. It only needs intent to make or threaten contact and the resulting apprehension. At one point, the common law understanding of assault required more than words alone, it also required an overt act. This understanding has changed, while words alone cannot be construed as assault, words coinciding with actions or circumstances that would put a person in reasonable apprehension that a harm or offensive contact was likely to occur would. For example, an actor shouting "I'm going to kill you" while not moving but in complete shadow and with a knife in their hand could be interpreted as assault.

Additionally, Fear is not required for an assault to occur, only anticipation of subsequent battery. A battery can occur without a preceding assault, such as if a person is struck in the back of the head. An assault can be an attempted battery.

For example, 'If Henry points a gun at Thomas, he has committed an assault. It makes no difference whether the gun is loaded,' But 'Henry will only commit a battery if he shoots the gun and hits Thomas'.

DNA paternity testing is the use of DNA profiles to determine whether an individual is the biological parent of another individual. Paternity testing can be especially important when the rights and duties of the father are in issue and a child's paternity is in doubt. Tests can also determine the likelihood of someone being a biological grandparent. Though genetic testing is the most reliable standard, older methods also exist, including ABO blood group typing, analysis of various other proteins and enzymes, or using human leukocyte antigen antigens. The current techniques for paternity testing are using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). Paternity testing can now also be performed while the woman is still pregnant from a blood draw.

DNA testing is currently the most advanced and accurate technology to determine parentage. In a DNA paternity test, the result (called the 'probability of parentage) is 0% when the alleged parent is not biologically related to the child, and the probability of parentage is typically 99.99% when the alleged parent is biologically related to the child. However, while almost all individuals have a single and distinct set of genes, rare individuals, known as "chimeras", have at least two different sets of genes, which can result in a false negative result if their reproductive tissue has a different genetic make-up from the tissue sampled for the test.

Credits.

Credits are allowed against AMT for foreign taxes and certain specified business credits.

The AMT foreign tax credit limitation is redetermined based on AMTI rather than regular taxable income. Thus, all adjustments and tax preference items above must be applied in computing the AMT foreign tax credit limitation.

AMT credit against regular tax.

After a taxpayer has paid AMT, a credit is allowed against regular tax in future years for the amount of AMT. The credit for individuals is generally limited to the amount of AMT generated by deferral items (for example, exercise of incentive stock options), as opposed to exclusion items (for example, state and local taxes). This credit is limited so that regular tax is not reduced below AMT for the year. Taxpayers may use a simplified method under which the AMT foreign tax credit limit is computed proportionately to the regular tax foreign tax credit limit. IRS Form 8801 is used to claim this credit.

Complexity.

The AMT is a tax of roughly 28% on adjusted gross income over $186,300 plus 26% of amounts less than $186,300 minus an exemption depending on filing status after adding back in most deductions. However, taxpayers must also perform all of the paperwork for a regular tax return and then all of the paperwork for Form 6251. Furthermore, affected taxpayers may have to calculate AMT versions of all carryforwards since the AMT carryforwards may be different from regular tax carryforwards. Once a taxpayer qualifies for AMT, he or she may have to calculate AMT versions of carryforward losses and AMT carryforward credits until they are used up in future years. The definitions of taxable income, deductible expenses, and exemptions differ on Form 6251 from those on Form 1040.

The complexity of the AMT paired with the history of last-minute annual patches adjusting the law create tax liability uncertainty for taxpayers. For the last ten years, Congress has passed one-year patches to mitigate negative effects, but they are typically passed close to the end of the year. This makes it difficult for taxpayers to determine their tax liability ahead of time. In addition, because the AMT was not indexed for inflation until 2013, the cost of annual patches rises every year.

Remedies.

In the United Kingdom, breach of contract is defined in the Unfair Contract Terms Act 1977 as:  non-performance,  poor performance,  part-performance, or  performance which is substantially different from what was reasonably expected. Innocent parties may repudiate (cancel) the contract only for a major breach (breach of condition), but they may always recover compensatory damages, provided that the breach has caused foreseeable loss.

It was not possible to sue the Crown in the UK for breach of contract before 1948. However, it was appreciated that contractors might be reluctant to deal on such a basis and claims were entertained under a petition of right that needed to be endorsed by the Home Secretary and Attorney-General. S.1 Crown Proceedings Act 1947 opened the Crown to ordinary contractual claims through the courts as for any other person.

History.

Whilst early rules of trade and barter have existed since ancient times, modern laws of contract in the West are traceable from the industrial revolution (1750 onwards), when increasing numbers worked in factories for a cash wage. In particular, the growing strength of the British economy and the adaptability and flexibility of the English common law led to a swift development of English contract law. Colonies within the British empire (including the USA and the Dominions) would adopt the law of the mother country. In the 20th century, the growth of export trade led to countries adopting international conventions, such as the Hague-Visby Rules and the UN Convention on Contracts for the International Sale of Goods, to promote uniform regulations.

Contract law is based on the principle expressed in the Latin phrase pacta sunt servanda, ("agreements must be kept"). The common law of contract originated with the now-defunct writ of assumpsit, which was originally a tort action based on reliance. Contract law falls within the general law of obligations, along with tort, unjust enrichment, and restitution.

Jurisdictions vary in their principles of freedom of contract. In common law jurisdictions such as England and the United States, a high degree of freedom is the norm. For example, in American law, it was determined in the 1901 case of Hurley v Eddingfield that a physician was permitted to deny treatment to a patient despite the lack of other available medical assistance and the patient's subsequent death. This is in contrast to the civil law, which typically applies certain overarching principles to disputes arising out of contract, as in the French Civil Code. Other legal systems such as Islamic law, socialist legal systems, and customary law have their own variations.

However, in both the European union and the United States, the need to prevent discrimination has eroded the full extent of freedom of contract. Legislation governing equality, equal pay, racial discrimination, disability discrimination and so on, has imposed limits of the full freedom of contract. For example, the Civil Rights Act of 1964 restricted private racial discrimination against African-Americans. In the early 20th century, the United States underwent the "Lochner era", in which the Supreme Court of the United States struck down economic regulations on the basis of freedom of contract and the Due Process Clause; these decisions were eventually overturned, and the Supreme Court established a deference to legislative statutes and regulations that restrict freedom of contract. The US Constitution contains a Contract Clause, but this has been interpreted as only restricting the retroactive impairment of contracts.

Intentional torts.

Intentional torts are any intentional acts that are reasonably foreseeable to cause harm to an individual, and that do so. Intentional torts have several subcategories:

 Torts against the person include assault, battery, false imprisonment, intentional infliction of emotional distress, and fraud, although the latter is also an economic tort.

Property torts involve any intentional interference with the property rights of the claimant (plaintiff). Those commonly recognized include trespass to land, trespass to chattels (personal property), and conversion.

An intentional tort requires an overt act, some form of intent, and causation. In most cases, transferred intent, which occurs when the defendant intends to injure an individual but actually ends up injuring another individual, will satisfy the intent requirement. Causation can be satisfied as long as the defendant was a substantial factor in causing the harm.

Statutory torts.

A statutory tort is like any other, in that it imposes duties on private or public parties, however they are created by the legislature, not the courts. For example, the European Union's Product Liability Directive imposes strict liability for defective products that harm people; such strict liability is not uncommon although not necessarily statutory.

As another example, in England common law liability of a landowner to guests or trespassers was replaced by the Occupiers' Liability Act 1957; a similar situation occurred in the U.S. State of California in which a judicial common law rule established in Rowland v Christian was amended through a 1985 statute. Statutory torts also spread across workplace health and safety laws and health and safety in food. In some cases federal or state statutes may preempt tort actions, which is particularly discussed in terms of the U.S. FDA Preemption; although actions in the United States for medical devices are preempted due to Riegel v Medtronic, Inc. (2008), actions for medical drugs are not due to Wyeth v Levine (2009).

Nuisance.

"Nuisance" is traditionally used to describe an activity which is harmful or annoying to others such as indecent conduct or a rubbish heap. Nuisances either affect private individuals (private nuisance) or the general public (public nuisance). The claimant can sue for most acts that interfere with their use and enjoyment of their land. In English law, whether activity was an illegal nuisance depended upon the area and whether the activity was "for the benefit of the commonwealth", with richer areas subject to a greater expectation of cleanliness and quiet. The case Jones v Powell (1629) provides an early example, in which a person's professional papers were damaged by the vapors of a neighboring brewery. Although the outcome of this case is unclear, Whitelocke of the Court of the King's Bench is recorded as saying that since the water supply in area was already contaminated, the nuisance was not actionable as it is "better that they should be spoiled than that the commonwealth stand in need of good liquor".

In English law, a related category of tort liability was created in the case of Rylands v Fletcher (1868): strict liability was established for a dangerous escape of some hazard, including water, fire, or animals as long as the cause was not remote. In Cambridge Water Co Ltd v Eastern Counties Leather plc (1994), chemicals from a factory seeped through a floor into the water table, contaminating East Anglia's water reservoirs. The Rylands rule remains in use in England and Wales. In Australian law, it has been merged into negligence.

A tort, in common law jurisdiction, is a civil wrong (other than breach of contract) that causes a claimant to suffer loss or harm, resulting in legal liability for the person who commits a tortious act. It can include intentional infliction of emotional distress, negligence, financial losses, injuries, invasion of privacy, and many other things. The word 'tort' stems from Old French via the Norman Conquest and Latin via the Roman Empire.

Tort law involves claims in an action seeking to obtain a private civil remedy, typically money damages. Tort claims may be compared to criminal law, which deals with criminal wrongs that are punishable by the state. A wrongful act, such as an assault and battery, may result in both a civil lawsuit and a criminal prosecution in countries where the civil and criminal legal systems are separate. Tort law may also be contrasted with contract law, which also provides civil remedies after breach of a duty that arises from a contract; but whereas the contractual obligation is one agreed to by the parties, obligations in both tort and criminal law are more fundamental and are imposed regardless of whether the parties have a contract. In both contract and tort, successful claimants must show that they have suffered foreseeable loss or harm as a direct result of the breach of duty.

Terminology.

The person who commits the act is called a tortfeasor. Although crimes may be torts, the cause of legal action in civil torts is not necessarily the result of criminal action; the harm in civil torts may be due to negligence, which does not amount to criminal negligence. The victim of the harm can recover their loss as damages in a lawsuit. To prevail, the plaintiff in the lawsuit, commonly referred to as the injured party, must show that the actions or lack of action was the legally recognizable cause of the harm. The equivalent of tort in civil law jurisdictions is "delict". Moreover, Tort law differs from Criminal law, whilst both contain punitive elements, Tort law is known to be more vindicatory and 'compensatory' by nature. 'The overall object of tort law is to define cases in which the law may justly hold one party liable to compensate another.'

Legal injuries are not limited to physical injuries and may include emotional, economic, or reputational injuries as well as violations of privacy, property, or constitutional rights. Torts comprise such varied topics as automobile accidents, false imprisonment, defamation, product liability, copyright infringement, and environmental pollution (toxic torts).

Compared to criminal cases, tort lawsuits have a lower burden of proof, namely "preponderance of evidence", rather than beyond a reasonable doubt. Sometimes a claimant may prevail in a tort case even if the defendant who allegedly caused harm were acquitted in an earlier criminal trial. For example, O J Simpson was acquitted in criminal court of murder but later found liable for the tort of wrongful death.

Both tort law and criminal law may impose liability where there is:

 intentional action. reckless behavior. Carelessness. product liability (without negligence) in the US & the EU. "innocence" (or blameless inadvertence) provided there is strict liability. Battery. Assault. Trespass.

Both laws also deter certain types of undesirable behavior through liability. However, in Criminal law the term 'guilty' is used whereas in Tort law this is not the case and 'liable' is used instead.

Defenses.

Vitiating factors constituting defenses to purported contract formation include:

Mistake (such as non est factum).

Incapacity, including mental incompetence and infancy/minority.

Duress.

Undue influence.

 Unconscionability.

Misrepresentation or fraud.

Frustration of purpose.

Such defenses operate to determine whether a purported contract is either (1) void or (2) voidable. Void contracts cannot be ratified by either party. Voidable contracts can be ratified.

Misrepresentation.

Misrepresentation means a false statement of fact made by one party to another party and has the effect of inducing that party into the contract. For example, under certain circumstances, false statements or promises made by a seller of goods regarding the quality or nature of the product that the seller has may constitute misrepresentation. A finding of misrepresentation allows for a remedy of rescission and sometimes damages depending on the type of misrepresentation.

In a court of law, to prove misrepresentation and/or fraud, there must be evidence that shows a claim was made, said claim was false, the party making the claim knew the claim was false, and that party's intention was for a transaction to occur based upon the false claim.

There are two types of misrepresentation: fraud in the factum and fraud in inducement. Fraud in the factum focuses on whether the party alleging misrepresentation knew they were creating a contract. If the party did not know that they were entering into a contract, there is no meeting of the minds, and the contract is void. Fraud in inducement focuses on misrepresentation attempting to get the party to enter into the contract. Misrepresentation of a material fact (if the party knew the truth, that party would not have entered into the contract) makes a contract voidable.

Remedies for defendants on defenses.

Setting aside the contract.

To rescind is to set aside or unmake a contract. There are four different ways in which contracts can be set aside. A contract may be deemed 'void', 'voidable' or 'unenforceable', or declared 'ineffective'. Voidness implies that a contract never came into existence. Voidability implies that one or both parties may declare a contract ineffective at their wish. Kill fees are paid by magazine publishers to authors when their articles are submitted on time but are subsequently not used for publication. When this occurs, the magazine cannot claim copyright for the "killed" assignment. Unenforceability implies that neither party may have recourse to a court for a remedy.

Ineffectiveness arises when a contract is terminated by order of a court, where a public body has failed to satisfy the requirements of public procurement law. This remedy was created by the Public Contracts (Amendments) Regulations 2009.

Disputes.

Procedure.

In many countries, in order to obtain damages for breach of contract or to obtain specific performance or other equitable relief, the aggrieved injured party may file a civil (non-criminal) lawsuit in court.

In England and Wales, a contract may be enforced by use of a claim, or in urgent cases by applying for an interim injunction to prevent a breach. Likewise, in the United States, an aggrieved party may apply for injunctive relief to prevent a threatened breach of contract, where such breach would result in irreparable harm that could not be adequately remedied by money damages.

Formalities and writing requirements for some contracts.

A contract is often evidenced in writing or by deed, the general rule is that a person who signs a contractual document will be bound by the terms in that document, this rule is referred to as the rule in L'Estrange v Graucob. This rule is approved by the High Court of Australia in Toll(FGCT) Pty Ltd v Alphapharm Pty Ltd. But a valid contract may (with some exceptions) be made orally or even by conduct. Remedies for breach of contract include damages (monetary compensation for loss) and, for serious breaches only, repudiation (for example, cancellation). The equitable remedy of specific performance, enforceable through an injunction, may be available if damages are insufficient.

Typically, contracts are oral or written, but written contracts have typically been preferred in common law legal systems; in 1677 England passed the Statute of Frauds which influenced similar statute of frauds laws in the United States and other countries such as Australia. In general, the Uniform Commercial Code as adopted in the United States requires a written contract for tangible product sales in excess of $500, and real estate contracts are required to be written. If the contract is not required by law to be written, an oral contract is valid and therefore legally binding. The United Kingdom has since replaced the original Statute of Frauds, but written contracts are still required for various circumstances such as land (through the Law of Property Act 1925).

Representations versus warranties.

Statements of fact in a contract or in obtaining the contract are considered to be either warranties or representations. Traditionally, warranties are factual promises which are enforced through a contract legal action, regardless of materiality, intent, or reliance. Representations are traditionally precontractual statements that allow for a tort-based action (such as the tort of deceit) if the misrepresentation is negligent or fraudulent; historically, a tort was the only action available, but by 1778, breach of warranty became a separate legal contractual action. In U.S. law, the distinction between the two is somewhat unclear; warranties are viewed as primarily contract-based legal action while negligent or fraudulent misrepresentations are tort-based, but there is a confusing mix of case law in the United States. In modern English law, sellers often avoid using the term 'represents' in order to avoid claims under the Misrepresentation Act 1967, while in America 'warrants and represents' is relatively common. Some modern commentators suggest avoiding the words and substituting 'state' or 'agree', and some model forms do not use the words; however, others disagree.

Statements in a contract may not be upheld if the court finds that the statements are subjective or promotional puffery. English courts may weigh the emphasis or relative knowledge in determining whether a statement is enforceable as part of the contract. In the English case of Bannerman v White the court upheld a rejection by a buyer of hops which had been treated with Sulphur since the buyer explicitly expressed the importance of this requirement. The relative knowledge of the parties may also be a factor, as in English case of Bissett v Wilkinson where the court did not find misrepresentation when a seller said that farmland being sold would carry 2000 sheep if worked by one team; the buyer was considered sufficiently knowledgeable to accept or reject the seller's opinion.

A contract is a legally binding agreement that defines and governs the rights and duties between or among its parties. A contract is legally enforceable when it meets the requirements of applicable law. A contract typically involves the exchange of goods, services, money, or a promise of any of those. In the event of a breach of contract, the injured party may seek judicial remedies such as damages or cancellation.

In the Anglo-American common law, formation of a contract generally requires an offer, acceptance, consideration, and mutual intent to be bound. Each party must be those who are binding by the contract. Although most oral contracts are binding, some types of contracts may require formalities such as being in writing or by deed.

In the civil law tradition, contract law is a branch of the law of obligations.

Each country recognized by private international law has its own national system of law to govern contracts. Although systems of contract law might have similarities, they may contain significant differences. Accordingly, many contracts contain a choice of law clause and a jurisdiction clause. These provisions set the laws of the country which will govern the contract, and the country or other forum in which disputes will be resolved, respectively. Failing express agreement on such matters in the contract itself, countries have rules to determine the law governing the contract and the jurisdiction for disputes. For example, European Member States apply Article 4 of the Rome I Regulation to decide the law governing the contract, and the Brussels I Regulation to decide jurisdiction.

Electronic contracts.

Entry into contracts online has become common. Many jurisdictions have passed e-signature laws that have made the electronic contract and signature as legally valid as a paper contract.

In India, E-contracts are governed by the Indian Contract Act (1872), according to which certain conditions need to be fulfilled while formulating a valid contract. Certain sections in the Information Technology Act (2000) also provide for validity of online contracts.

In some U.S. states, email exchanges have become binding contracts. New York courts in 2016 held that the principles of real estate contracts apply equally to electronic communications and electronic signatures, so long as “its contents and subscription meet all requirements of the governing statute” and pursuant to the Electronic Signatures and Records Act (ESRA).

Intention to be legally bound.

In commercial agreements it is presumed that parties intend to be legally bound unless the parties expressly state the opposite as in a heads of agreement document. For example, in Rose & Frank Co v JR Crompton & Bros Ltd, an agreement between two business parties was not enforced because an "honor clause" in the document stated "this is not a commercial or legal agreement, but is only a statement of the intention of the parties".

In contrast, domestic and social agreements such as those between children and parents are typically unenforceable on the basis of public policy. For example, in the English case Balfour v Balfour a husband agreed to give his wife £30 a month while he was away from home, but the court refused to enforce the agreement when the husband stopped paying. In contrast, in Merritt v Merritt the court enforced an agreement between an estranged couple because the circumstances suggested their agreement was intended to have legal consequences.

Negligence.

Amongst unintentional torts one finds negligence as being the most common source of common law. Most Americans are under the impression that most people can sue for any type of negligence, but it is untrue in most US jurisdictions (partly because negligence is one of the few torts for which ordinary people can and do obtain liability insurance.) It is a form of extracontractual liability that is based upon a failure to comply with the duty of care of a reasonable person, which failure is the actual cause and proximate cause of damages. That is, but for the tortfeasor's act or omission, the damages to the plaintiff would not have been incurred, and the damages were a reasonably foreseeable consequence of the tortious conduct.

Some jurisdictions recognize one or more designations less than actual intentional wrongdoing, but more egregious than mere negligence, such as "wanton", "reckless" or "despicable" conduct. A finding in those states that a defendant's conduct was "wanton," "reckless" or "despicable", rather than merely negligent, can be significant because certain defenses, such as contributory negligence, are often unavailable when such conduct is the cause of the damages.

Breach.

Breach is ordinarily established by showing that the defendant failed to exercise reasonable care. Some courts use the terms ordinary care or prudent care instead. Conduct is typically considered to be unreasonable when the disadvantages outweigh the advantages. Judge Learned Hand famously reduced this to algebraic form in United States v Carroll Towing Company:

This means that if the burden of exercising more care is less than the probability of damage or harm multiplied by the severity of the expected loss, and a person fails to undertake the burden, he is not exercising reasonable care and is thus breaching his duty to do so (assuming he has one). In other words, the burden of prevention is less than the probability that the injury will occur multiplied by the gravity of the harm/injury. Under this formula, duty changes as circumstances change—if the cost of prevention increases, then the duty to prevent decreases; if the likelihood of damage or the severity of the potential damage increases, then duty to prevent increases.
