How to Brief a Case: The Eight Parts, in Class and in Practice

A case brief is a structured one-page summary of a court opinion, written so you can recall and reuse the case without rereading it. A complete brief has eight parts: the caption and citation, the facts, the procedural history, the issue, the holding, the reasoning, the disposition, and a notes section for dicta, concurrences, and dissents.

Nearly every guide to briefing is written for one reader: a 1L preparing for a cold call. That leaves out the people who brief cases for a living. Paralegals summarize the authorities behind an opposing motion. Associates work a line of cases before a memo. Trial teams build bench books. So this guide runs the case brief format component by component, then shows where practice briefing departs from the classroom, and ends with a complete worked case brief example built on the most famous torts case in the American canon.

What are the parts of a case brief?

Louisiana State University's 1L research guide says every brief should include the caption, facts, procedural history, issues, holdings, rationale, disposition, and concurring and dissenting opinions. That is the full case brief template; everything else is preference. The table below keeps LSU's list and adjusts two names: rationale becomes reasoning, and the concurrence-and-dissent slot widens into a notes section that also catches dicta.

Caption and citation. The case name, the deciding court, and the year. A student adds the casebook page; a practitioner records the full reporter citation, because a cite that has to be looked up again has already failed.

Facts. Only the legally relevant ones: the facts that affected the outcome. The LSU guide's example is the color of the parties' cars, which seldom matters. If the holding would survive the fact being different, the fact does not belong.

Procedural history. Who sued whom for what, what each court below did, and how the case arrived at this court. It tells you which judgment is under review; posture controls the standard of review, and a case decided on a motion to dismiss supports a different argument than the same words after trial.

Issue. The legal question, written as a question, with enough of the operative facts embedded that it can be answered yes or no. A vague issue ("was the defendant negligent?") is useless; a sharp one does half the analytical work.

Holding. The court's answer to the issue, stated as the rule the court applied. This is the sentence that binds future courts under stare decisis. Separating it from everything else the court said is the point of the exercise.

Reasoning. Why the rule produced this result on these facts. The LSU guide's point: you must understand the reasoning to apply it to other fact situations. A brief that captures the holding without the reasoning can be recited but not used.

Disposition. What happened to the judgment below: affirmed, reversed, remanded, vacated, complaint dismissed. The holding is a rule; the disposition is an order. Do not conflate them.

Notes and dicta. LexisNexis's pre-law briefing guide defines dicta as commentary about the decision that was not the basis for the decision. Dicta, concurrences, dissents, and your own reactions go here, walled off from the holding. The wall is the discipline: never mistake what a court said for what it decided.

How do you brief a case, step by step?

1. Read the whole opinion first. The LSU guide is blunt: do not try to brief a case while reading it for the first time. You cannot know which facts are legally relevant until you know how the case comes out. If isolating the holding in a dense opinion is still slow going, start with our guide to how to read a court opinion, the skill this one builds on.
2. Mark up on the second pass. Flag the facts the court leans on, the question it frames, and the sentence where it answers. The brief should assemble itself from the margins.
3. Write the issue and holding as a pair. They are one question and its answer, and drafting them together keeps both honest. The pair is also what the IRAC method (issue, rule, application, conclusion) runs on at exam time: they become the I and the R.
4. Fill in facts, procedural history, reasoning, and disposition. LexisNexis compresses the length rule to four words: a brief should be brief. One page is the ceiling.
5. Add notes last. Dicta worth remembering, a dissent worth tracking, and, for practitioners, the line students never write: how this case maps onto yours.

Why do practitioners brief cases differently than students?

A student brief exists to survive a cold call and feed an outline. A practice brief exists to be trusted later, by someone who never read the case: the attorney you support, the colleague who inherits the matter, you in eight months when the issue resurfaces at a deposition. Three things change.

It is written for the file, not for memory. Full citation, court, date, and judge, so the brief drops into work product cite-ready. A student can shortcut the caption; in practice the brief itself is the source of truth, and it outlives its author. The associate rotates off the matter. The brief stays.

The client's facts sit next to the court's facts. A practice brief ends by mapping the holding onto the matter: what this case gives you, what distinguishes it, what the other side will say about it. That mapping becomes the discussion section when the brief feeds a legal memo, which is where most practice briefs are headed.

Depth follows the case's role. The controlling authority gets all eight parts. A see-also cite gets a caption, a holding, and a pincite. Nobody in practice briefs every case at cold-call depth; knowing which treatment a case deserves is itself the judgment.

Case briefing for paralegals is its own steady genre: summarizing the authorities behind an opposing motion so the attorney reads five pages instead of ninety, building the trial notebook's authority section, keeping the matter file current when a new opinion lands. Our guide to legal research for paralegals covers where briefing sits in that workflow. It is also the work AI compresses. CaseRead, the AI associate that knows your matter, makes that first summarizing pass across the public law and the firm's own files together, citing only sources it actually retrieved and flagging anything it cannot verify, so the human hours go to the mapping and the judgment calls.

A worked case brief example: Palsgraf v. Long Island Railroad

Here is the full format applied to a real opinion: the 1928 New York Court of Appeals decision every American torts student briefs.

Caption: Palsgraf v. Long Island R.R. Co., 248 N.Y. 339, 162 N.E. 99 (1928) (Cardozo, C.J.).

Facts: Helen Palsgraf stood on the defendant's platform after buying a ticket to Rockaway Beach. Two men ran to catch a departing train. One made it without mishap; the other, carrying a small package wrapped in newspaper, jumped aboard and seemed about to fall. A guard on the car reached forward to help him in while another on the platform pushed him from behind, and the package was dislodged, fell on the rails, and exploded. It held fireworks; nothing in its appearance gave notice of the contents. The shock knocked down scales at the other end of the platform, many feet away, and the scales struck and injured Palsgraf.

Procedural history: A jury found for Palsgraf. A divided Appellate Division affirmed. The railroad appealed to the New York Court of Appeals.

Issue: Does a defendant whose conduct creates no foreseeable risk of harm to the plaintiff owe that plaintiff a duty of care, when the same conduct was arguably negligent toward someone else?

Holding: No. Negligence, like risk, is a term of relation: "The risk reasonably to be perceived defines the duty to be obeyed." A defendant owes a duty only to plaintiffs within the range of apprehension.

Reasoning: Nothing about a newspaper-wrapped parcel suggested peril to a person standing far down the platform; to the eye of ordinary vigilance, the orbit of the danger is the orbit of the duty. A wrong to the package's holder, if there was one, was not a wrong to Palsgraf. She had to show a violation of a duty running to her, and foreseeability is what draws its boundary.

Disposition: Reversed; complaint dismissed, with costs in all courts.

Notes: 4–3. Andrews, J., dissenting: everyone owes the world at large a duty to refrain from acts that unreasonably threaten the safety of others, so the real question is proximate cause, not duty. Courts still weigh his frame against Cardozo's nearly a century later.

Notice what one page does. The opinion measures the package at about fifteen inches; the brief keeps only "small" and the newspaper wrapping, because lack of notice is what the holding turns on. The issue and holding read as one question and its answer. And the notes line earns its keep: a brief that recorded only the majority would miss that the dissent became the counter-position half of tort law still argues from.

The brief is the habit; the tools should keep up

Briefing transfers unchanged from the first week of law school to the last year of practice: read the opinion, isolate what was decided from what was said, write it down in a form someone can trust later. What changes is the volume. When a motion lands citing thirty cases, paste them into the free Hallucination Shield before anyone starts reading: it checks each citation against real court data for existence and support — up to 25 per run, so a thirty-case motion takes two passes — no signup, so the briefing hours go to authorities that are real and to calls no tool can make. And when you want that first pass running inside the matter file itself, that is the rest of CaseRead.

Frequently asked questions

How long should a case brief be? One page. A case brief is a working summary, not a rewrite of the opinion; a brief that runs past a page usually means the facts section is carrying details that never affected the outcome. Keep all eight parts, but hold each one to what helps you recall or reuse the case.

What is the IRAC method? IRAC stands for Issue, Rule, Application, Conclusion, the standard structure for written legal analysis: state the legal question, state the governing rule, apply the rule to the facts, and answer the question. A case brief is not written in IRAC, but it feeds it: the issue and holding supply the I and the R, and the facts and reasoning are raw material for the application.

What's the difference between a case brief and a legal brief? A case brief is a private one-page summary of a decided case, written for your own use in class, in a memo, or in a matter file. A legal brief is a persuasive document filed with a court, arguing for a result on behalf of a client, and it often runs dozens of pages. Nobody files a case brief. The two share a name and almost nothing else.

What is dicta in a case brief? Dicta is language in an opinion that was not necessary to the decision: commentary, hypotheticals, or observations about questions the court did not have to answer. It belongs in the notes section of a brief, clearly separated from the holding, because the holding binds future courts and dicta does not. Marking that line is one of the main analytical payoffs of briefing a case at all.

Do paralegals write case briefs? Yes, routinely. Litigation paralegals brief cases so an attorney can absorb a line of authority quickly: summarizing the cases an opposing motion relies on, building a bench book before trial, or keeping a matter file current. A practice brief leads with the full citation, the holding, and how the case maps onto the client's facts, because it is written to be reused, not recited in class.
