What is a case brief?
A case brief is a structured one-page summary of a court opinion. Law students write briefs before class so they can answer cold-call questions accurately and so they have a usable artifact when building outlines for finals. The case brief format has been mostly stable since the early 20th century — what varies is how much detail each professor expects and which sections matter for the class's exam style.
The interactive template above implements the three most-used formats. Pick the one that matches your class and start filling in fields — the preview updates live, and you can copy or download the result when you're done.
IRAC vs. FIRAC vs. standard case brief
These three formats answer different jobs:
- Standard case brief. The long-form summary used in 1L casebooks and most class prep. Includes citation, parties, procedural history, facts, issue, holding, rule, reasoning, any concurrence or dissent, and a significance note. This is what your professor expects you to have in front of you on a cold call.
- IRAC. Issue, Rule, Application, Conclusion. The compact analytical structure used on law school exam essays and in legal memoranda. Drop the procedural history and skip facts you can't use to apply the rule — IRAC is about analysis, not recall.
- FIRAC. IRAC with an explicit Facts section in front. Some professors and writing instructors prefer FIRAC because it forces you to surface the legally relevant facts before you start applying the rule. Functionally identical to IRAC for grading purposes; structurally clearer.
A common workflow: write a standard brief for class, then collapse the same case into IRAC when it goes into your outline. The template above lets you toggle formats without losing your text — switch and the same data renders under whichever sections that format uses.
Anatomy of a case brief
What goes in each section, and what to skip.
- Citation. Full Bluebook citation — Hanna v. Plumer, 380 U.S. 460 (1965). Italicize party names and the “v.” If you're unsure of the format, use our Bluebook citation generator.
- Parties. Who's who and what role they play — plaintiff, defendant, appellant, appellee, petitioner. Include their relationship to the dispute (executor, lessee, employer) because that shapes the legal analysis.
- Procedural history. How the case got to the deciding court. Trial outcome, appeals, grants of cert. Two or three sentences. Do not narrate every motion.
- Facts. Only the legally relevant facts. If you can't connect a fact to an element of the rule, leave it out. Aim for 3-6 sentences for most cases.
- Issue. The legal question framed as a yes/no. Whether Federal Rule 4(d)(1) or Massachusetts state law governs service of process in a federal diversity case. Some professors want narrow issues; some want broad. Ask early.
- Holding. The court's narrow answer to the issue. Yes — Federal Rule 4(d)(1) controls. One sentence.
- Rule of law. The broader legal principle the holding announces or applies. This is what you cite on the exam, so be precise about elements, conditions, and exceptions.
- Reasoning. Why the court reached this holding. Doctrine, policy, precedent, statutory interpretation — whatever the court actually relied on. This is the longest section and the one you'll re-read most when outlining.
- Concurrence and dissent. Only when the professor is likely to ask. If a case is famous for the dissent (Palsgraf, Lochner, Dred Scott), brief it. Otherwise note “Dissent: not assigned.”
- Significance. Two sentences on why this case matters — for the doctrine, for class, for your outline.
Worked example: Hanna v. Plumer
Click “Load real example” in the template above and select Hanna v. Plumer. The fields fill in with the kind of brief a strong 1L would write — concise issue framing, holding stated as a yes/no, rule that captures the two-track Erie framework rather than just “FRCPs control.” Toggle between Standard, IRAC, and FIRAC to see how the same underlying case compresses into different formats.
The other two pre-loaded examples (Marbury v. Madison and Palsgraf v. Long Island R.R.) cover the other two first-semester staples — judicial review and the foreseeability /duty doctrine in tort. All three are also available as full case briefs in our free case brief library (150+ cases).
Five mistakes that ruin case briefs
- Copying the casebook's facts paragraph verbatim. The casebook editor wrote that paragraph for context — not for your cold call. Your job is to compress it to the facts that matter for the rule the court applies.
- Phrasing the issue as a topic, not a question. “Personal jurisdiction” is a topic. “Whether International Shoe's minimum contacts test extends to a foreign manufacturer that sells through an independent distributor” is an issue. Professors grade the second.
- Conflating holding and rule. The holding is what this court did to these parties. The rule is the doctrine future courts will apply. Stating only the holding makes the brief useless for the exam.
- Skipping the dissent on a famous case. If you recognize the case name, the dissent is probably load-bearing. Palsgraf without Andrews is not really Palsgraf.
- Briefing every case at the same depth. Some cases are doctrine-establishing (Marbury, Erie, International Shoe) and deserve full briefs. Some are illustrative footnotes the professor mentions once. Calibrate.
