How to brief a case with FIRAC, and when to stop
A case brief in five parts: Facts, Issue, Rule, Analysis, Conclusion. What each part is for, what to leave out, and why your briefs should get shorter as the semester goes on.
A case brief is a reduction, not a summary. Five parts do the work: the Facts the court treated as relevant, the Issue it had to decide, the Rule it applied, the Analysis that connected the two, and the Conclusion it reached. That is FIRAC, and half a page of it is usually enough.
The mistake that costs first-year students the most hours is treating a brief as a shorter copy of the case. A brief you can read in twenty seconds and still answer a cold call from is doing its job. A brief that reproduces the opinion is a transcription exercise you will not reread.
What each part is actually for
Facts
Write only the facts the court relied on. Every opinion contains background that makes the story readable and changes nothing, and separating the two is the first real legal skill the exercise teaches.
The test is counterfactual: if you flip this fact, does the outcome change? The buyer was a merchant rather than a consumer, the letter arrived after the deadline rather than before, the officer saw the bag open rather than closed. Those go in. The color of the car does not, unless the case turns on identification.
Include the procedural posture in a line, because it sets what the court is allowed to do. A ruling on a motion to dismiss assumes the plaintiff’s version is true; a ruling after a jury verdict does not. Students who skip posture end up quoting a case for a proposition it never decided.
Issue
One sentence, phrased as a question, specific enough that the answer could go either way. “Whether the contract was valid” is not an issue; it is a topic. “Whether an emailed acceptance is effective on sending when the offer requires written acceptance” is an issue, because a court could plausibly answer it either way and you can see which facts would push it.
Some cases have two or three issues. Number them and give each its own rule and analysis. A brief that fuses three issues into one paragraph is where confusion starts.
Rule
This is the sentence you will still be using in December, so write it as a rule of general application, not as a statement about these parties. Not “the court held that Smith’s letter was not an acceptance” but “an acceptance that varies a material term of the offer is a counteroffer and terminates the power of acceptance.”
Where the rule has elements, break them out as a list. Elements are how exam questions are graded: each one is a place where an issue spotter can put a fact that makes the element arguable. A rule written as a paragraph hides the seams; a rule written as four numbered elements shows you exactly where the fight will be.
Analysis
The reasoning, compressed. Why did the court apply the rule the way it did, which facts did it lean on, what did it do with the losing side’s best argument, and what policy or precedent did it invoke?
This is the part students cut first and the part professors ask about most. A cold call rarely stops at “what did the court hold.” It goes to “why,” and then to “would it come out the same way if the letter had arrived a day earlier.” The analysis is where you have already thought about that.
Conclusion
The holding and the disposition, in a line: what the rule produced on these facts, and what the court did about it, such as affirmed, reversed, remanded, or vacated. Add one line for a notable concurrence or dissent.
A worked shape
Here is the whole thing at the length it should be, filled with a generic contracts fact pattern so the shape is visible:
Case: Parker v. Wynn, citation, state supreme court
Posture: Appeal from summary judgment for defendant.
Facts: Offer to sell equipment, acceptance required “in writing.” Buyer emailed acceptance within the deadline, adding a delivery date not in the offer. Seller sold elsewhere.
Issue: Whether an acceptance adding a delivery term is an acceptance or a counteroffer where the offer requires written acceptance.
Rule: A purported acceptance that adds or varies a material term operates as a counteroffer and terminates the offeree’s power of acceptance. Whether a term is material is judged by whether it alters the parties’ obligations in a way a reasonable party would care about.
Analysis: The court treated the delivery date as material because it shifted the risk of a seasonal market. It rejected the argument that email cannot satisfy a writing requirement, holding the medium and the content are separate questions. The dissent would have read the added date as a proposal rather than a condition.
Conclusion: Counteroffer, no contract. Affirmed.
That is under 200 words and it answers every question a professor is likely to ask about it.
What to leave out
- Long quotations. One quoted sentence, where the exact words are the rule. Beyond that you are copying.
- Every fact in the opinion. See above: if flipping it changes nothing, it is background.
- Your opinion of the outcome, unless you mark it as yours. Keep a separate line for reactions so you never mistake your view for the court’s holding.
- Restating the rule three times in Rule, Analysis and Conclusion. Say it once, apply it once, resolve it once.
Briefs should get shorter
Full FIRAC briefs are training wheels, and they are supposed to come off. Most students follow roughly this arc:
| Stage | What briefing looks like | Why |
|---|---|---|
| Weeks 1 to 4 | Full written FIRAC for every case | You are learning which parts of an opinion carry weight |
| Weeks 4 to 8 | Full briefs for rule-setting cases, book briefing for the rest | You can now spot the parts on the page |
| Week 8 onward | Book briefing plus rules straight into the outline | Reading feeds the outline, which is what the exam tests |
Book briefing means marking up the casebook itself: brackets around the material facts, a vertical line next to the rule, and a two line note in the top margin giving the issue and the holding. It is faster and it keeps you in the text, where cold calls actually happen.
The arc matters because reading load, not doctrine, is what breaks most first semesters. If briefing takes three hours a night in November, something is wrong with the method rather than with you.
How briefs feed the outline
A brief is an input. The output is the course outline, which is organized by doctrine rather than by the order the casebook happened to use.
The habit worth building early: when you finish a brief, copy the rule sentence into the outline under the right heading, with the case name next to it as an example. Do that as you go and outlining stops being a separate project you dread in November. Skip it and you will reread forty cases to extract what you already extracted once.
What survives to the exam is the rule, the elements, and one line of what the case was about so you can cite it as an illustration. The brief itself does not come to the exam, even in an open book one, because nobody has time to search a stack of briefs while the clock runs.
Keeping the reading load visible
The reason briefing collapses is rarely a single bad week. It is that the backlog is invisible: pages assigned and pages actually read drift apart quietly, and you notice in the week before midterms.
A reading log fixes that cheaply. Per class, per day: pages assigned, pages done, whether it is briefed. Two numbers and a checkbox, and the gap becomes a thing you can see on a Sunday instead of a surprise.
LawSchoolOS is the offline version of that idea: a casebook reading log per class with assigned against done, FIRAC briefs you can search by case name, per-class outline progress, and a practice exam log. It is one file that runs in your browser, on your laptop and phone, with nothing stored anywhere but your device. If a notebook and a spreadsheet already work for you, keep them; the format matters less than seeing the backlog before it sees you.
For the other number that creeps up on people, the GPA calculator will tell you what a given semester does to a cumulative average, which is worth knowing before journal and OCI deadlines rather than after.
If you have fallen behind
Do not brief your way out of it chronologically. That is the trap: you start at the oldest unread case and never reach the material the next class is actually on.
Work backwards instead. Read for the next class first so you are current going forward, then fill gaps by rule rather than by case, using the syllabus headings to see which rules you are missing. A rule you can state and apply covers a case you never briefed. The reverse is not true.
And if you are staring at the reading without starting it, that is a starting problem rather than a comprehension problem, and it has its own fixes that have nothing to do with law.
This is study advice, not legal advice, and every professor has their own preferences about briefing. When yours tells you to do it differently, do it their way.
Frequently asked questions
What does FIRAC stand for?
Facts, Issue, Rule, Analysis, Conclusion. It is IRAC with the facts put back in front, which matters for a case brief because a court's rule only makes sense against the facts it was decided on. IRAC and CRAC are the same skeleton used for writing answers rather than for reading cases.
How long should a case brief be?
Most cases fit on half a page, and a long one fits on a page. If a brief runs longer than the part of the casebook you are briefing, you are copying rather than reducing. The useful test is whether you can answer a cold call from the brief alone without looking back at the book.
Should I brief every case?
Brief everything for the first few weeks, because that is how you learn what is load bearing. After that, most students move to book briefing for routine cases and write full briefs only for the ones that set out or change a rule. The point of briefing is learning to read, so it makes sense that the method changes once you can.
What is book briefing?
Annotating the casebook itself instead of writing a separate document: brackets around the facts that mattered, a line down the margin next to the rule, a note in the top margin naming the issue and the holding in one sentence each. It is faster, it keeps you inside the text, and it works once you can already spot those parts reliably.
Do case briefs help on the exam?
Not directly. Exams ask you to apply rules to new facts, so what you carry into the exam is the outline, not the stack of briefs. Briefs matter because they are where the rules come from and because a rule you extracted yourself is one you can actually use under time pressure.
What do I do about concurrences and dissents?
Note them in one line each and say why they exist: a concurrence that reaches the same result on different reasoning, or a dissent that would draw the rule more narrowly. Professors ask about them because the disagreement shows where the rule is unsettled, and that is where exam questions are written.
