The 20 Cases Every 1L Reads (and Why They Matter)

Law school casebooks vary, but the first-year canon barely does. Whatever school you land at and whichever edition of the casebook you're handed, the same core set of cases keeps showing up, because these are the cases that built the doctrines everything else sits on. Knowing them before the semester starts won't replace your reading, but it gives you a scaffold. You'll recognize where each new case fits instead of meeting all of them cold at once.

Below are twenty cases you're almost certain to read in your first year, grouped by course, with a short note on why each one earned its spot. Every case links to a full brief in the same IRAC format. If you've never briefed a case before, start with our guide on how to brief a case and read these with that structure in mind.

Civil Procedure

Civ Pro is where 1Ls tend to panic, and it usually opens with personal jurisdiction, the question of which court gets to haul you in.

Pennoyer v. Neff (1877). The starting point for personal jurisdiction. It ties a court's power over you to physical presence and territory, a rigid rule the rest of the semester spends taking apart. You have to understand Pennoyer to appreciate everything that replaces it.

International Shoe Co. v. Washington (1945). The case that swapped Pennoyer's territorial rule for "minimum contacts" and "traditional notions of fair play and substantial justice." It's a strong candidate for the single most important case of your first year. Every jurisdiction question after this one runs straight through it.

Erie Railroad Co. v. Tompkins (1938). When a federal court hears a state-law claim, whose law applies? Erie says state substantive law governs, and the line it draws between substance and procedure will follow you around for weeks. Dense, foundational, and unavoidable.

Contracts

Contracts rewards you for holding two ideas at once: what the parties agreed to, and what the law will actually enforce.

Lucy v. Zehmer (1954). A farm sold on the back of a restaurant check after a night of drinking. The case teaches that contract formation is judged by objective outward expression, not secret intent. Zehmer's claim that he was only joking couldn't beat what a reasonable person would have understood him to mean.

Hawkins v. McGee (1929). The "hairy hand" case. A doctor promised a perfect hand and delivered a hairy one. It sets the expectation measure of damages, meaning you get the benefit of your bargain, and it's the case every Contracts professor reaches for to explain why the law compensates the promise rather than the effort.

Hadley v. Baxendale (1854). The rule on consequential damages: you can only recover losses that were foreseeable when the contract was made. A broken crankshaft, a delayed delivery, a shut-down mill, and a principle courts still apply today.

Carlill v. Carbolic Smoke Ball Co. (1893). A Victorian ad promised £100 to anyone who used the company's product and still caught the flu. The court held it a binding unilateral offer. It's charming, it's memorable, and it's the cleanest illustration of offer and acceptance you'll read all year.

Torts

Torts is the most story-driven of the 1L courses, and its canon is full of vivid, teachable disasters.

Palsgraf v. Long Island R.R. (1928). Fireworks, a dropped package, a falling scale, and Judge Cardozo's rule that a defendant owes a duty only to plaintiffs within the zone of foreseeable harm. It's the foundational case on duty and proximate cause, and probably the most famous tort case in America.

MacPherson v. Buick Motor Co. (1916). Cardozo again, this time dismantling the privity requirement and opening manufacturers up to liability for defective products. It's the bridge between old contract-bound negligence and modern products liability.

United States v. Carroll Towing Co. (1947). Judge Learned Hand boils negligence down to an equation: liability turns on whether the burden of precaution is less than the probability of harm times how bad that harm would be. This is the "Hand formula," the moment torts meets economics.

Vosburg v. Putney (1891). A schoolboy kicks another under a classroom desk and ends up liable for far more injury than anyone saw coming. It's the case behind the "eggshell skull" rule and the principle that you take your victim as you find them.

Garratt v. Dailey (1955). A five-year-old pulls a chair out from under his aunt. The case defines intent for battery as knowing that harmful or offensive contact is substantially certain to result, not as a desire to hurt anyone. It's the classic intentional-tort intent case.

Constitutional Law

Con Law is where you argue about power, and the canon is the story of how the Court claimed and shaped it.

Marbury v. Madison (1803). The case that established judicial review, the Court's power to strike down laws that violate the Constitution. Everything in Con Law rests on it. If you read one case before law school starts, make it this one.

McCulloch v. Maryland (1819). Can Congress charter a national bank, and can a state tax it? Chief Justice Marshall's answers built the doctrine of implied federal powers and national supremacy. The Necessary and Proper Clause starts its life here.

Wickard v. Filburn (1942). A farmer grows wheat for his own use and still gets swept under the federal power to regulate interstate commerce. It's the high-water mark of Commerce Clause reach, and the case every later commerce dispute measures itself against.

Lochner v. New York (1905). The Court strikes down a maximum-hours law for bakers in the name of freedom of contract. Today it's taught as a cautionary tale, the symbol of an era of judicial overreach the Court later walked away from.

Brown v. Board of Education (1954). Separate is inherently unequal. The unanimous decision that ended de jure school segregation and reshaped equal protection. Its reasoning and its place in constitutional history make it impossible to skip.

Criminal Law and Procedure

Miranda v. Arizona (1966). The warnings you can already recite from television. The Court held that custodial interrogation requires telling suspects about their rights to silence and to counsel. It's the foundation of modern interrogation law.

Katz v. United States (1967). A phone booth, a wiretap, and the birth of the "reasonable expectation of privacy" test under the Fourth Amendment. It moved privacy from a property question to an expectations question, and it still governs search doctrine today.

Property

Pierson v. Post (1805). Two men and a fox. Who owns a wild animal, the one who chased it or the one who killed it? The case teaches first possession and the idea that ownership takes more than pursuit. It's a deceptively deep way to start Property.

How to use this list

Don't try to memorize twenty briefs in a weekend. Read each one to understand the single principle it stands for, the ones above, and let the details fill in when you actually meet the case in class. The point of knowing the canon early is recognition. When your professor assigns International Shoe in week three, you'll already know why it matters, and you can spend your reading energy on the reasoning instead of the panic.

When you're ready, browse the full library for the rest of your syllabus. Every brief is written by attorneys in IRAC format, with the relevant facts and issue free on every case.
