United States tort law

This article addresses torts in United States law. As such, it covers primarily common law. Moreover, it provides general rules, as individual states all have separate civil codes. There are three general categories of torts: intentional torts, negligence, and strict liability torts.

Intentional torts involve situations in which the defendant desires or knows to a substantial certainty that his act will cause the plaintiff damage. They include battery, assault, false imprisonment, intentional infliction of emotional distress ("IIED"), trespass to land, trespass to chattels, conversion, invasion of privacy, malicious prosecution, abuse of process, fraud, inducing breach of contract, intentional interference with business relations, and defamation of character (libel/slander).

The elements of most intentional torts follow the same pattern: intent, act, result, and causation.

This element typically requires the defendant to desire or know to a substantial certainty that something will occur as a result of his act. Therefore, the term intent, for purposes of this section, always includes either desire or knowledge to a substantial certainty.

For an example in battery, Dave shoots a gun into a crowd of people because he is specifically trying to hit someone with a bullet. This element would be satisfied, as David had an actual desire to procure the harm required for this tort. Alternatively, Dave shoots a gun into a crowd of people for some reason and genuinely hopes no one gets hit but knows that it is virtually inevitable that someone will actually get hit. This element would still be satisfied, as David had knowledge to a substantial certainty that harm would result.
