tort

Tort comes from Anglo-French tort (wrong, harm, injury) and Old French tort, from Medieval Latin tortum (a wrong), the neuter past participle of torquere (to twist, to distort). The Latin torquere gives English 'torque,' 'torture,' 'contort,' 'extort,' and 'distort' — all of them involving twisting, bending, or forcible turning. In Anglo-French legal usage of the medieval period, a tort was a wrong — a deviation from the straight and lawful path of conduct, a twisted action that harmed another. The word entered English legal vocabulary in the sixteenth century and became, over the following centuries, the technical term for the branch of civil law that deals with non-contractual civil wrongs: harms done to persons or property that give rise to a right of compensation regardless of whether any contract was breached or crime committed.

The law of tort distinguishes civil from criminal liability. When a person is criminally prosecuted for assault, the state brings the action, and the punishment is imprisonment or fine payable to the state. When the same person is sued in tort for battery, the victim brings the action, and the remedy is compensation — damages — payable to the victim. The same physical act can give rise to both criminal prosecution and civil tort liability, and the standard of proof differs: criminal conviction requires proof beyond reasonable doubt, while civil tort liability requires only proof on the balance of probabilities. O.J. Simpson, acquitted of criminal murder in 1995, was found civilly liable for the tort of wrongful death in 1997, the same act producing different legal outcomes under different standards.

The major categories of tort developed gradually in English common law and were shaped by decisions across centuries of litigation. Negligence — the failure to take reasonable care resulting in foreseeable harm — is the dominant tort in the modern era, governing everything from medical malpractice to road accidents. It required centuries of judicial development before it reached its modern form, and the landmark case of Donoghue v. Stevenson (1932) — in which a woman found a decomposed snail in a ginger beer bottle and sued the manufacturer — established the modern duty of care principle that underlies negligence law. The law of torts is, in a profound sense, the accumulated record of every category of harm that English and American courts have recognized as deserving compensation.

Tort law shapes daily life in ways that are rarely visible because most tortious acts are resolved through insurance rather than litigation. The driver who hits your car, the surgeon who makes an avoidable error, the manufacturer whose product injures you, the employer who permits a dangerous workplace — all of these create tort liability that is typically managed through professional indemnity insurance, motor insurance, and product liability coverage. The insurance system that mediates most civil harm in modern societies is built on the structure of tort law: the categories of legally compensable harm define the risks that must be insured against. Tort law is the invisible foundation of risk distribution in modern economies.
