Torts may be categorized in several ways: one such way is to divide them into Negligence, Intentional Torts, and Quasi-Torts.
The standard action in tort is negligence. The tort of negligence provides a cause of action leading to damages, or to relief, in each case designed to protect legal rights, including those of personal safety, property, and, in some cases, intangible economic interests. Negligence actions include claims coming primarily from car accidents and personal injury accidents of many kinds, including clinical negligence, worker's negligence and so forth. Product liability cases, such as those involving warranties, may also be considered negligence actions, but there is frequently a significant overlay of additional lawful content.
Intentional torts include, among others, certain torts arising from the occupation or use of land. The tort of nuisance, for example, involves strict liability for a neighbor who interferes with another's enjoyment of his real property. Trespass allows owners to sue for entrances by a person (or his structure, such as an overhanging building) on their land. Several intentional torts do not involve land. Examples include false imprisonment, the tort of unlawfully arresting or detaining someone, and defamation (in some jurisdictions split into libel and slander), where false information is broadcast and damages the plaintiff's reputation.
In some cases, the development of tort law has spurred lawmakers to create alternative solutions to disputes. For example, in some areas, workers' compensation laws arose as a legislative response to court rulings restricting the extent to which employees could sue their employers in respect of injuries sustained during employment. In other cases, legal commentary has led to the development of new causes of action outside the traditional common law torts. These are loosely grouped into quasi-torts or liability torts.
