Negligence per se is a doctrine in US law whereby an act is considered negligent because it violates a statute. The doctrine is effectively a form of strict liability.
Negligence is a failure to exercise appropriate and/or ethical ruled care expected to be exercised amongst specified circumstances. The area of tort law known as negligence involves harm caused by failing to act as a form of carelessness possibly with extenuating circumstances. The core concept of negligence is that people should exercise reasonable care in their actions, by taking account of the potential harm that they might foreseeably cause to other people or property.
In law and insurance, a proximate cause is an event sufficiently related to an injury that the courts deem the event to be the cause of that injury. There are two types of causation in the law: cause-in-fact, and proximate cause. Cause-in-fact is determined by the "but for" test: But for the action, the result would not have happened. The action is a necessary condition, but may not be a sufficient condition, for the resulting injury. A few circumstances exist where the but-for test is ineffective. Since but-for causation is very easy to show, a second test is used to determine if an action is close enough to a harm in a "chain of events" to be legally valid. This test is called proximate cause. Proximate cause is a key principle of insurance and is concerned with how the loss or damage actually occurred. There are several competing theories of proximate cause. For an act to be deemed to cause a harm, both tests must be met; proximate cause is a legal limitation on cause-in-fact.
Res ipsa loquitur is a doctrine in the common law and Roman-Dutch law jurisdictions under which a court can infer negligence from the very nature of an accident or injury in the absence of direct evidence on how any defendant behaved in the context of tort litigation. Although specific criteria differ by jurisdiction, an action typically must satisfy the following elements of negligence: the existence of a duty of care, breach of appropriate standard of care, causation, and injury. In res ipsa loquitur, the existence of the first three elements is inferred from the existence of injury that does not ordinarily occur without negligence.
A tort is a civil wrong that causes a claimant to suffer loss or harm, resulting in legal liability for the person who commits the tortious act. Tort law can be contrasted with criminal law, which deals with criminal wrongs that are punishable by the state. While criminal law aims to punish individuals who commit crimes, tort law aims to compensate individuals who suffer harm as a result of the actions of others. Some wrongful acts, such as assault and battery, can 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 provides civil remedies after breach of a duty that arises from a contract. Obligations in both tort and criminal law are more fundamental and are imposed regardless of whether the parties have a contract.
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.
Assumption of risk is a defense, specifically an affirmative defense, in the law of torts, which bars or reduces a plaintiff's right to recovery against a negligent tortfeasor if the defendant can demonstrate that the plaintiff voluntarily and knowingly assumed the risks at issue inherent to the dangerous activity in which the plaintiff was participating at the time of their injury.
In some common law jurisdictions, contributory negligence is a defense to a tort claim based on negligence. If it is available, the defense completely bars plaintiffs from any recovery if they contribute to their own injury through their own negligence.
Comparative negligence, called non-absolute contributory negligence outside the United States, is a partial legal defense that reduces the amount of damages that a plaintiff can recover in a negligence-based claim, based upon the degree to which the plaintiff's own negligence contributed to cause the injury. When the defense is asserted, the factfinder, usually a jury, must decide the degree to which the plaintiff's negligence and the combined negligence of all other relevant actors all contributed to cause the plaintiff's damages. It is a modification of the doctrine of contributory negligence that disallows any recovery by a plaintiff whose negligence contributed even minimally to causing the damages.
In tort law, the standard of care is the only degree of prudence and caution required of an individual who is under a duty of care.
Ex turpi causa non oritur actio is a legal doctrine which states that a plaintiff will be unable to pursue legal relief and damages if it arises in connection with their own tortious act. Particularly relevant in the law of contract, tort and trusts, ex turpi causa is also known as the illegality defence, since a defendant may plead that even though, for instance, he broke a contract, conducted himself negligently or broke an equitable duty, nevertheless a claimant by reason of his own illegality cannot sue. The UK Supreme Court provided a thorough reconsideration of the doctrine in 2016 in Patel v Mirza.
Comparative responsibility is a doctrine of tort law that compares the fault of each party in a lawsuit for a single injury. Comparative responsibility may apply to intentional torts as well as negligence and encompasses the doctrine of comparative negligence.
Li v. Yellow Cab Co., 13 Cal.3d 804, 532 P.2d 1226 (1975), commonly referred to simply as Li, is a California Supreme Court case that judicially embraced comparative negligence in California tort law and rejected strict contributory negligence.
In the USA, the rescue doctrine of the law of torts holds that if a tortfeasor creates a circumstance that places the tort victim in danger, the tortfeasor is liable not only for the harm caused to the victim, but also the harm caused to any person injured in an effort to rescue that victim. This doctrine was originally promulgated by Benjamin N. Cardozo in the 1921 case, Wagner v. Int'l Ry. Co. There, writing for the Court of Appeals of New York, Cardozo stated: "Danger invites rescue. The cry of distress is the summons to relief [...] The emergency begets the man. The wrongdoer may not have foreseen the coming of a deliverer. He is accountable as if he had." The rescue doctrine was established nineteen years later, in the landmark case of Cote v. Palmer.
The following outline is provided as an overview of and introduction to tort law in common law jurisdictions:
Ultramares Corporation v. Touche, 174 N.E. 441 (1932) is a US tort law case regarding negligent misstatement, decided by Cardozo, C.J. It contained the now famous line on "floodgates" that the law should not admit "to a liability in an indeterminate amount for an indeterminate time to an indeterminate class."
Davies v. Mann, 152 Eng. Rep. 588 (1882), was an English case that contained the first formulation of the "last clear chance" or “last opportunity rule” doctrine in negligence law.
The avoidable consequences rule is a concept in United States jurisprudence which comes from a common-law rule barring recovery of damages that a tort victim "could have avoided by the use of reasonable effort or expenditure after the commission of the tort." This concept recognizes as fact, that if a plaintiff is injured by a defendant, that the plaintiff must take reasonable steps to avoid aggravating the injuries caused by the defendant.
- Except as stated in Subsection (2), one injured by the tort of another is not entitled to recover damages for any harm that he could have avoided by the use of reasonable effort or expenditure after the commission of the tort.
- One is not prevented from recovering damages for a particular harm resulting from a tort if the tortfeasor intended the harm or was aware of it and was recklessly disregardful of it, unless the injured person with knowledge of the danger of the harm intentionally or heedlessly failed to protect his own interests.
The civil liability of a recreational diver may include a duty of care to another diver during a dive. Breach of this duty that is a proximate cause of injury or loss to the other diver may lead to civil litigation for damages in compensation for the injury or loss suffered.
Chapman v Hearse is a significant case in common law related to duty of care, reasonable foreseeability and novus actus interveniens within the tort of negligence. The case concerned three parties; Chapman who drove negligently, Dr Cherry who assisted him on the side of the road, and Hearse who, in driving negligently, killed Dr Cherry while he was assisting Chapman. In the Supreme Court of South Australia, Hearse was found liable for damages to Dr Cherry's estate under the Wrongs Act 1936. Hearse sought to reclaim damages from Chapman due to his alleged contributory negligence; Chapman was found liable to one quarter of the damages. Chapman appealed the case to the High Court of Australia on August 8, 1961, but it was dismissed as the results of his negligence were deemed reasonably foreseeable. A duty of care was established between Chapman and the deceased and his claim of novus actus interveniens was rejected. Dr Cherry was considered a 'rescuer' and his respective rights remained.
