Tort Law in the United States

Tort law governs civil wrongs that cause harm to individuals, allowing injured parties to seek compensation through the court system outside of criminal prosecution. It spans a broad range of conduct — from automobile collisions and medical errors to defamatory statements and trespasses on property. Because tort claims are adjudicated predominantly under state common law, the rules vary by jurisdiction, though federal courts apply state tort doctrine in diversity cases under the framework established in Erie Railroad Co. v. Tompkins (304 U.S. 64, 1938). Understanding tort law's structure, elements, and limitations is essential for navigating civil law vs criminal law distinctions and assessing how how a civil lawsuit works in practice.

Definition and scope

A tort is a civil wrong, other than a breach of contract, for which a court provides a remedy in the form of damages or injunctive relief. The Restatement (Third) of Torts, published by the American Law Institute (ALI), provides the most comprehensive reference framework for courts and practitioners across the United States, though it carries persuasive rather than binding authority.

Tort law divides into three principal categories:

1. Intentional torts — wrongful acts committed with intent to cause harm or with knowledge that harm is substantially certain to result. Examples include battery, assault, false imprisonment, intentional infliction of emotional distress, trespass to land, and conversion of property.
2. Negligence — the broadest category, covering failures to exercise the degree of care that a reasonably prudent person would exercise under the same circumstances.
3. Strict liability — liability imposed regardless of intent or negligence, applied in contexts such as abnormally dangerous activities and product defects. The Restatement (Second) of Torts § 402A (ALI, 1965) established the foundational strict liability rule for defective products that most state courts adopted.

Tort law operates separately from criminal law: a single act — such as a drunk-driving collision — can generate both a criminal prosecution by the state and a tort claim by an injured party. The burden of proof standards differ sharply between these tracks; tort plaintiffs must establish liability by a preponderance of the evidence (greater than 50%), while criminal conviction requires proof beyond a reasonable doubt.

How it works

A tort claim follows a structured analytical path regardless of category.

Elements of a negligence claim (the most litigated tort):

1. Duty — the defendant owed a legally recognized duty of care to the plaintiff.
2. Breach — the defendant's conduct fell below the applicable standard of care.
3. Causation — the breach was both the actual cause (but-for causation) and the proximate (legal) cause of the plaintiff's harm.
4. Damages — the plaintiff suffered a quantifiable harm, whether physical, economic, or emotional.

For intentional torts, the element structure differs. Battery, for example, requires only an intentional act resulting in harmful or offensive contact — no proof of injury-caused damages is required for nominal liability, though actual damages expand available recovery.

Under strict liability for products, a plaintiff under Restatement (Third) of Torts: Products Liability (ALI, 1998) must show the product was defective (manufacturing defect, design defect, or failure to warn), the defect existed when it left the defendant's control, and the defect caused the plaintiff's injury.

Damages in tort fall into three classes:

• Compensatory damages — economic (medical expenses, lost wages) and non-economic (pain and suffering, loss of consortium).
• Nominal damages — symbolic awards when a legal right is violated but no measurable harm results.
• Punitive damages — awarded to punish egregious conduct; the U.S. Supreme Court in BMW of North America, Inc. v. Gore (517 U.S. 559, 1996) established that due process limits punitive awards, with a ratio of punitive to compensatory damages exceeding 10:1 generally viewed as constitutionally suspect.

Defenses include contributory negligence, comparative fault, assumption of risk, and statutory immunities. 46 states and the District of Columbia use some form of comparative fault rather than the older contributory negligence bar (Uniform Law Commission, comparative fault surveys).

Common scenarios

Tort claims arise across virtually every area of daily life. The most frequently litigated categories include:

• Motor vehicle negligence — drivers owed a duty of reasonable care; breach, causation, and injury constitute the core dispute in the majority of state civil dockets.
• Medical malpractice — a specialized negligence tort where the standard of care is defined by expert testimony concerning accepted medical practice, governed by state medical liability statutes in all 50 states.
• Premises liability — property owners' duty of care to visitors varies by the visitor's status (invitee, licensee, or trespasser) under common law classifications codified in state case law.
• Products liability — manufacturers, distributors, and retailers face claims under strict liability, negligence, or warranty theories when defective goods cause harm; the Consumer Product Safety Commission (CPSC) maintains recall databases that frequently appear as evidence in such litigation.
• Defamation — libel (written) and slander (spoken) claims require proof of a false statement of fact, publication to a third party, fault (actual malice for public figures per New York Times Co. v. Sullivan, 376 U.S. 254, 1964), and damages.

Decision boundaries

Several threshold questions determine whether a tort claim proceeds or is barred before the merits are reached.

Statutes of limitations impose strict filing deadlines. Personal injury claims carry a 2-year limitation period in the majority of states, though periods range from 1 year (Kentucky, Tennessee) to 6 years depending on the tort category and jurisdiction. Missing the applicable deadline is an absolute procedural bar; the statutes of limitations in US law reference covers these cutoffs in detail.

Intentional tort vs. negligence is a critical classification boundary. Intentional torts generally cannot be covered by standard liability insurance policies (Insurance Services Office standard CGL forms exclude expected or intended injury), while negligent acts are typically insurable. This distinction directly affects litigation strategy and settlement dynamics.

Federal vs. state court is a jurisdictional question addressed under 28 U.S.C. § 1332 (diversity jurisdiction), which permits federal adjudication of state tort claims when parties are citizens of different states and the amount in controversy exceeds $75,000 (28 U.S.C. § 1332, via Cornell LII). Federal courts apply state substantive tort law under Erie but federal procedural rules under the Federal Rules of Civil Procedure.

Government defendants face special rules. The Federal Tort Claims Act (28 U.S.C. §§ 2671–2680) waives sovereign immunity for negligent acts by federal employees acting within the scope of employment, but carves out 13 enumerated exceptions — including the discretionary function exception — that foreclose large categories of claims (FTCA overview, U.S. Department of Justice). State tort claims against government entities require compliance with separate administrative claim presentation requirements that vary by state.

Comparative vs. contributory fault determines whether a plaintiff's own negligence bars or reduces recovery. In the 4 states (Alabama, Maryland, North Carolina, Virginia) and the District of Columbia that retain pure contributory negligence, any plaintiff fault — even 1% — eliminates recovery entirely. The 46 comparative fault jurisdictions reduce, rather than eliminate, recovery proportionally, though 33 of those states bar recovery when the plaintiff's fault reaches or exceeds 50% (modified comparative fault systems).

The interplay between legal precedent and stare decisis and state legislatures means tort doctrine shifts incrementally as appellate courts refine duty, causation, and damages rules — and as legislatures enact tort reform statutes capping non-economic or punitive damages in specific sectors.
