Tort

• 1. Introduction

  ›

  Tort is one of the foundational concepts of civil law, a category of legal wrong so broad it encompasses everything from a neighbor's rubbish heap to a corporation releasing toxic chemicals into a water table. The word itself entered legal usage in the 1580s, though different words described similar ideas long before that. A tort is not a crime, and it is not a broken contract. It sits in its own category: a civil wrong, other than breach of contract, that causes someone to suffer loss or harm and triggers legal liability for whoever committed it.

  When Mrs. Donoghue drank from an opaque bottle and found a decomposed snail inside, she had no contract with the manufacturer, Mr. Stevenson. She could not sue for breach of contract. Instead, she sued for negligence, and the Scottish case that followed, decided by the House of Lords in 1932, established what we now call the tort of negligence across the entire English-speaking world.

  Tort law's reach is staggering. Automobile accidents, false imprisonment, product liability, copyright infringement, environmental pollution, and defamation all fall under its umbrella. The questions it raises are equally sweeping: Who owes a duty of care to whom? When does an unintentional injury become someone's legal responsibility? And what happens in societies that decide to scrap tort law for personal injury entirely, as New Zealand did with the creation of the Accident Compensation Corporation?

  Torts and crimes in common law share a single origin: the Germanic system of compensatory fines for wrongs, in which no clear line separated crime from other harm. Under Anglo-Saxon law, most wrongs required a payment in money, made either to the wronged person or to their clan. The fine called weregild was imposed specifically for murder, with the explicit aim of preventing blood feuds from spiraling out of control.

  Alfred the Great's Doom Book drew one of the earliest formal distinctions between unintentional injuries and intentional ones, and it calibrated culpability according to the status, age, and gender of the parties involved. Some offenses were classified as botleas, meaning "without remedy": theft, open murder, arson, and treason against one's lord could not be compensated. Those convicted of a botleas crime were left entirely at the king's mercy. Objects or creatures that caused a death were destroyed outright, under a doctrine known as deodands.

  After the Norman Conquest, fines flowed only to courts or the king, and the revenues became significant. A wrong began to be called a tort or trespass, and a division opened between civil pleas and pleas of the crown. The petty assizes, established in 1166, created specific remedies for interference with possession of freehold land. By the 1250s, the writ of trespass had become available by right, though it was restricted to forcible breaches of the king's peace and interference with land. The English case Beaulieu v Finglam, decided in 1401, imposed strict liability for the escape of fire and for the release of cattle, reflecting how central the control of fire was in medieval communities with limited firefighting resources.

  Donoghue v Stevenson, decided in 1932, did not simply resolve one woman's claim against one bottler. It brought England into alignment with the United States on a fundamental question and established negligence as a distinct tort, rather than merely an element inside other specific actions. To win a negligence claim in most common law jurisdictions, a plaintiff must prove four things: that the defendant owed a duty of care, that the defendant breached that duty, that the breach caused an injury, and that the injury was a reasonably foreseeable consequence of the defendant's conduct.

  The 1928 American case Palsgraf v. Long Island Railroad Co. had already exerted a heavy influence on the British judges who would decide Donoghue four years later. What duty of care means has since produced a rich body of competing tests across different jurisdictions. English courts rely on the tripartite test from Caparo Industries plc v Dickman: harm must be reasonably foreseeable, the parties must be in a relationship of proximity, and it must be fair, just, and reasonable to impose a duty. Singapore's leading case, Spandeck Engineering v Defence Science and Technology Agency, built on an earlier English authority and established a two-step universal test centered on proximate cause and public policy, one that applies regardless of the specific circumstances of a given case.

  The defence of contributory negligence has its own deep history. Butterfield v. Forrester, decided in 1809, established the principle in England. The American version was once harsher: any fault by the victim, even one percent, eliminated the entire damages award. Many states found that approach too severe and shifted to a comparative negligence system that reduces damages in proportion to the plaintiff's share of fault. As of 2007, only a handful of states, including North Carolina and Maryland, still apply the older contributory negligence standard.

  Intentional torts cover acts that are reasonably foreseeable to cause harm and actually do so. They divide into several recognized families. Torts against the person include assault, battery, false imprisonment, and the intentional infliction of emotional distress. Property torts address deliberate interference with ownership rights: trespass to land, trespass to chattels, and conversion. Dignitary torts protect honor, reputation, and privacy, covering defamation, invasion of privacy, breach of confidence, and malicious prosecution.

  Nuisance law captures a different category of harm. Jones v Powell, decided in 1629, provides an early illustration: a person's professional papers were damaged by vapors drifting from a neighboring brewery. Whitelocke of the Court of the King's Bench was recorded as noting that since the local water supply was already contaminated, the nuisance was not actionable because "it is better that they should be spoiled than that the commonwealth stand in need of good liquor." The Rylands v Fletcher case in 1868 created strict liability for the dangerous escape of any hazard from land, whether water, fire, or animals, provided the cause was not too remote. In Cambridge Water Co Ltd v Eastern Counties Leather plc, decided in 1994, chemicals from a factory seeped through a floor into a water table and contaminated reservoirs across East Anglia.

  Economic torts form a third branch: tortious interference with trade or contract, fraud, injurious falsehood, and negligent misrepresentation. The economic loss rule, which began with a California case in 1965 involving strict liability for product defects, became a source of ongoing confusion across American courts. The U.S. Supreme Court adopted the doctrine in 1986. In 2010, the supreme court of Washington state replaced it entirely with what it called an independent duty doctrine.

• 5. Defences and Limits on Liability

  ›

  Tort law does not simply open a door for every plaintiff. Three principal defences in common law jurisdictions can reduce or eliminate liability entirely. The first is consent, captured in the Latin maxim volenti non fit injuria, meaning no injury is done to a person who consents. Spectators at a hockey game, for instance, are generally assumed to accept the risk of a puck leaving the ice. Signed waivers make that assumption explicit.

  Vicarious liability stretches responsibility beyond the direct tortfeasor. If a shop employee spills cleaning liquid on a supermarket floor and a customer is injured, the plaintiff may sue either the employee or the employer. The doctrine rests on the principle of respondeat superior, meaning that an employer answers for the acts of their agent. Whether this is truly justified on grounds of efficient risk allocation, or whether it simply reflects the practical search for a solvent defendant, is a question that continues to generate academic debate.

  Indian tort law developed its own distinct approach to liability for hazardous industrial activity. Under the English precedent set by Rylands v Fletcher, strict liability applied only to damage to land and its interests. Indian courts built on that foundation but departed from it in the rule established in M. C. Mehta v. Union of India, creating a doctrine of absolute liability: an enterprise engaged in hazardous activity is liable without any exceptions to everyone affected by an accident arising from that activity, not merely to those with interests in land. New Zealand took the most radical path of all. Following recommendations from the Royal Commission in 1967, the country scrapped personal injury tort law and medical malpractice tort law alike and replaced both with the Accident Compensation Corporation, a universal no-fault insurance system designed to give equal treatment to all victims regardless of who was at fault.

• 6. Diverging Legal Traditions

  ›

  Oliver Wendell Holmes, Jr. wrote on torts in the 1880s, and those writings have been described as the first serious attempt in the common law world to give torts both a coherent structure and a distinctive substantive domain. Blackstone's Commentaries, published in the late 18th century, had already used the word tort and devoted a volume to private wrongs, but it was Holmes who gave the subject its theoretical spine.

  French tort law flows from a different source: the Napoleonic Code, which together with the German Burgerliches Gesetzbuch forms the basis for private law in most civil law countries. French law's governing principle is that all injuries give rise to a remedy, though the injury must be certain, direct, and must affect a legitimate interest. The BGB, enacted in 1900, reflects a different philosophy rooted in 19th century classical liberalism and places far greater emphasis on protecting freedom of action. The two codes represent a major schism in civil law jurisprudence, and because most civil law jurisdictions on every continent modeled their own codes on one or the other, their philosophical differences ripple forward to the present day.

  Mainland China adopted a comprehensive civil code in 2021, Book Seven of which is titled Tort Liability and codifies seven distinct categories, including product liability, medical malpractice, environmental pollution, and liability for damage caused by domesticated animals. Article 179 of Book One lists eleven remedies available for any of those torts, ranging from cessation of infringement to the extension of apologies. Israel, meanwhile, codifies common law tort principles in the Tort Ordinance, which was originally passed under British rule, enacted by British Mandate of Palestine authorities in 1944, and took effect in 1947.

• 7. The Scots and Roman-Dutch Tradition

  ›

  Scots and Roman-Dutch law operate on a set of broad principles that differ from both civil codes and English common law. There is no exhaustive list of named delicts in either system. If conduct appears wrongful, the law provides a remedy even when no prior case addressed the same situation directly.

  The two primary remedies under these systems trace their names to Roman law. The actio legis Aquiliae addresses patrimonial loss, meaning economic damages. The actio iniuriarum provides for violations of non-patrimonial interests: dignitas and fama, honor and reputation. The two are not mutually exclusive. A plaintiff may pursue both simultaneously if the harm suffered falls into both categories. Roman-Dutch law, though not Scots law, adds a distinct action specifically for pain and suffering and psychiatric injury.

  In South Africa and neighboring countries, Roman-Dutch delict law survived the arrival of British colonial rule because the United Kingdom preserved it after annexing Dutch settlements. Neighboring British colonies later adopted South African law through reception statutes. Roman-Dutch law also forms the basis of Sri Lanka's legal system. In Scots law, the aquilian action has expanded beyond its original scope and now covers both patrimonial and certain types of non-patrimonial loss, particularly personal injury. The underlying principle: wherever a defender intentionally harms the pursuer, and the interest harmed is regarded as reparable, the defender incurs delictual liability.
