What is personal injury law?
Personal injury is the part of tort law dealing with harm to your body or mind, as opposed to harm to property or business. Car crashes, slip-and-falls, dog bites, defective products, and medical errors all live here.
It's civil, not criminal. The goal isn't punishment (mostly); it's compensation, making the injured person "whole" with money, since nobody can undo the injury itself.
- Three main theories
- Negligence, strict liability, intentional torts
- Who decides the rules
- Mostly states, through case law and statutes
- How most cases end
- Settlement, often with an insurance company
- How lawyers are often paid
- Contingency fee: a percentage of any recovery, nothing if you lose (terms vary)
Negligence: the four elements every claim needs
Most personal injury cases are negligence cases. To win, the plaintiff generally has to prove all four:
- Duty: the defendant owed a duty of reasonable care (drivers to others on the road, stores to customers).
- Breach: they failed to act like a reasonably careful person would.
- Causation: the breach actually caused the injury, and the harm was a foreseeable kind ("proximate cause").
- Damages: real, provable harm.
Two classic cases every law student meets: Palsgraf v. Long Island Railroad Co., 248 N.Y. 339 (1928), where Judge Cardozo limited duty to foreseeable plaintiffs, and United States v. Carroll Towing Co., 159 F.2d 169 (2d Cir. 1947), where Judge Learned Hand framed breach as a cost-benefit test: if the burden of precaution is less than the probability of harm times its severity, failing to take it is negligent. Full breakdown: the four elements of negligence.
Palsgraf has the strangest facts in legal history: a package of fireworks, a jostled passenger, a scale falling at the far end of a platform. It's taught everywhere because it forces one hard question: how far should responsibility reach?
How a personal injury claim works, step by step
- Get care and document everything: medical records, photos, witness names, police or incident reports.
- Notify insurers: usually the at-fault party's insurer handles the claim.
- Demand and negotiation: a demand letter lays out injuries and costs; most cases settle here.
- Filing suit: if no deal, a complaint is filed in court before the statute of limitations runs.
- Discovery: both sides exchange evidence, take depositions, hire experts.
- Mediation or trial: many courts push mediation; only a small share reach a jury verdict.
Deadlines are unforgiving. Statutes of limitations for injury claims differ by state, often in the range of one to a few years, with special rules for minors, government defendants, and medical cases. Miss it and the claim is usually gone. See personal injury statutes of limitations.
Fault rules, strict liability, and damages
What if you were partly at fault? States split. A few (Alabama, Maryland, North Carolina, Virginia, and D.C.) still use contributory negligence, where any fault by the plaintiff can bar recovery. Most use comparative negligence, reducing damages by the plaintiff's share; California adopted the "pure" version in Li v. Yellow Cab Co. (1975). Details: comparative vs. contributory negligence.
For defective products, many states apply strict liability: no need to prove carelessness, just a defect that caused injury. The path ran from MacPherson v. Buick Motor Co. (N.Y. 1916) to Greenman v. Yuba Power Products (Cal. 1963).
| Type of damages | What it covers |
|---|---|
| Economic (compensatory) | Medical bills, lost wages, future care |
| Non-economic (compensatory) | Pain and suffering, emotional distress, loss of enjoyment; some states cap these, especially in malpractice |
| Punitive | Extra damages for especially reckless or malicious conduct; limited by due process (BMW v. Gore, 1996; State Farm v. Campbell, 2003) |
More on the difference: compensatory vs. punitive damages.
The McDonald's coffee case: what really happened
Liebeck v. McDonald's Restaurants (N.M. Dist. Ct. 1994) is the most misunderstood tort case in America. Stella Liebeck, 79, spilled coffee in her lap as a passenger in a parked car. She suffered third-degree burns and needed skin grafts.
The jury heard evidence that McDonald's served coffee at roughly 180–190°F and had received hundreds of prior burn complaints. It found Liebeck 20% at fault, reducing compensatory damages from $200,000 to $160,000, and awarded $2.7 million in punitive damages, which the judge cut to $480,000. The parties then settled confidentially.
So "frivolous lawsuit" isn't quite the story. Full case: product liability and the McDonald's coffee case.
U.S. personal injury law vs. Korean tort law
| United States | South Korea | |
|---|---|---|
| Basic rule | State common law of negligence | Civil Act Art. 750: intentional or negligent unlawful act causing damage |
| Emotional harm | Pain and suffering, decided by juries | Consolation money (위자료, Art. 751), set by judges |
| Punitive damages | Available in most states | Generally no; limited multiple damages in specific statutes (e.g., up to 3x under the Product Liability Act since 2018) |
| Time limit | Varies by state | 3 years from knowing of damage and wrongdoer, 10 years from the act (Art. 766) |
| Juries | Common in civil trials | No civil juries |

Criticism: tort reform and access to justice
"Tort reform" advocates argue that large verdicts drive up insurance premiums and the cost of medical care, encourage defensive medicine, and reward lawyers more than victims. Their fixes include damage caps, limits on contingency fees, and stricter rules on expert testimony.
Critics of tort reform respond that caps hit the most seriously injured hardest, especially people without big wage losses like children, retirees, and stay-at-home parents. They also point out that the civil justice system is often the only way ordinary people can hold large companies accountable, and that cases like Liebeck were distorted in public memory.
At its core, tort law is society's answer to a simple question: when someone gets hurt, who pays? Every reform debate is really an argument about how to split that bill between victims, wrongdoers, and everyone else.
Using personal injury law in study and real life
- Exam method: walk through duty → breach → causation → damages, then defenses (comparative fault, assumption of risk).
- Connections: workplace injuries usually go through workers' compensation instead of lawsuits; see at-will employment. Defective-product claims overlap with consumer protection law, and waivers in contracts tie to freedom of contract.
- Korean study material: 민사 재판 절차와 형사 재판 절차: 변론준비절차, 공판·약식·즉결심판과 모의재판 원·피고 견해 explains how Korean civil and criminal trials proceed, handy for understanding where a damages claim goes procedurally.
- What do you need to prove in a personal injury case?
- Usually negligence: a duty of care, a breach of that duty, causation, and actual damages.
- How long do I have to file a personal injury claim?
- It depends on the state and type of claim; deadlines often range from one to a few years, and claims against governments can require much earlier notice.
- Did the McDonald's coffee plaintiff get millions?
- No. The jury awarded $2.7 million in punitive damages, but the judge reduced it to $480,000, and the parties later settled confidentially.
- Is this legal advice?
- No. This page is general information; consult a licensed attorney in your state about a specific injury.
