How to Study Law Cases: Briefing, IRAC and Exam Prep
Law students learn the law mostly through cases. Each decision explains how a rule works in a real dispute, and a course may cover hundreds. The reading is dense, the language is unfamiliar and the point of each case is often buried. Without a method, it is easy to read endlessly and still not know what the law is.
This guide gives a practical way to read, brief and use cases, mainly for common law courses, such as those in the United States, the United Kingdom, Canada and Australia.
Why cases are hard to read
Cases are written by judges for lawyers and not for students. They mix facts, procedure, argument and policy, often with long quotations from older cases. The rule you need may be stated once, in the middle, or only implied. Different judges can reason differently, and the case may be one of several that together make a doctrine.
Reading with a clear purpose solves most of this. You are looking for what happened, what question the court answered, what it decided and why.
Read the case twice
Read quickly for the story first, then again slowly, marking the facts that matter, the question the court faced, what it decided and the reasons it gave.
Write a short brief
Record the facts, the procedural history, the issue, the holding, the reasoning and any dissent or notes, in your own words and in a few lines each.
State the rule
Write the legal rule the case stands for in one or two sentences, and note where it applies and where it might not, so you can use it in answers.
Build an outline by topic
Group cases and rules under legal topics in a course outline, showing how each rule is tested and how cases differ from each other.
Practice applying the rules
Answer past hypotheticals using an issue, rule, application, conclusion structure, under time, and compare your answers with model responses or feedback.
Read in two passes
On the first pass, read quickly for the story: who the parties are, what happened and who won. Do not stop for every unfamiliar word. On the second pass, read slowly, marking:
- the facts that mattered to the decision;
- the question the court said it had to answer;
- the court's answer;
- the reasoning used.
Many students find it useful to look up unfamiliar legal terms in a law dictionary on the second pass.
The case brief
A brief is a short summary you write in your own words. A common format:
| Part | What to write |
|---|---|
| Case name and court | Citation and year |
| Facts | The key facts that matter, in a few lines |
| Procedural history | How the case reached this court |
| Issue | The legal question, usually as a yes or no question |
| Holding | The court's answer |
| Reasoning | Why the court decided as it did |
| Rule | The principle for future cases |
| Notes | Dissents, links to other cases, questions |
Keep it to half a page. If the brief runs as long as the case, you have copied instead of summarizing.
Finding the rule
The rule is what you will use in exams. It is the legal principle the case establishes, usually phrased in terms that apply beyond its facts. Write it as a short sentence: "A contract requires offer, acceptance and consideration." Then note the key facts that triggered it. If you cannot state the rule, reread the reasoning, and ask what the court would do with a similar case.
Understand how cases relate
Cases do not stand alone. Ask:
- Does this case follow earlier ones, or change them?
- What would be different if one fact were different?
- Which later cases cite it, and for what?
- Do the judges disagree, and about what?
Comparing cases in a table, with columns for the facts, the holding and the reasoning, makes the differences clear. This is what exams test.
Build an outline
A course outline is your main study document. Organize it by legal topic, not by case date. Under each topic, list:
- the rules, in plain language;
- the elements, such as the parts that must all be proved;
- the key cases, each with a one-line summary;
- exceptions and defenses;
- policy reasons behind the rules.
Update it weekly, so it is a living record of the course. Before the exam it should be short enough to review in a few hours.
Learn the rules by heart
Law exams usually require you to state rules accurately and apply them. Memorize the elements of each rule with flashcards or a short list, and practice reciting them without notes. Use the techniques in our guide to memorizing information quickly, such as chunking and acronyms, for long lists of elements.
Practice with IRAC
Most law exam answers follow a structure such as IRAC:
- Issue: state the legal question the facts raise.
- Rule: state the relevant rule, with the case if useful.
- Application: apply the rule to the facts, point by point, arguing both sides where it is uncertain.
- Conclusion: state the likely outcome.
The application is the part that earns the most marks, and it is where students are weakest. Use facts from the question and link each one to an element of the rule. Practicing the structure on past questions makes it natural.
Practice with hypotheticals
Past exam questions and hypotheticals are the best preparation. A good routine:
- Read the problem and underline the facts.
- Spend five to ten minutes planning the issues and rules.
- Write your answer under time.
- Compare with a model answer or feedback and note what you missed.
- Add missed rules and issues to your outline.
Doing many questions teaches you to spot issues, which is half of the exam.
Preparing for class
Reading before class, briefly briefing each case and noting questions makes lectures far more useful. If you may be asked to state a case, rehearse a two-minute summary: facts, issue, holding, reasoning. This also serves as your first review.
Study groups
Groups are popular in law school. Use them to quiz each other on rules, argue both sides of a hypothetical and compare outlines. Do not just copy someone else's outline, because building it is how you learn. Check your integrity rules, which usually allow discussion but require individual work.
Reading cases outside the courtroom setting
Cases come from different courts and different periods, so check the weight of each. Note the court, because a higher court's decision usually binds lower ones. Note whether a case is still good law, and what later cases did with it. Statutes and regulations matter as much as cases in many courses, so read the legislation too, and learn how courts interpret it. Your instructor's notes on what is central will save time.
Handling long cases and heavy reading
Law reading loads are large. Use a triage approach: read the key cases closely, skim the long ones for the facts, issue and holding, and use summaries only after you have read the original. Set a time limit for each case, say 30 to 45 minutes, and stop at it. Brief while reading, not afterward, so you do not have to go back. Keep a running list of questions to raise in class, and use the discussion to fix misunderstandings.
Common mistakes
- Briefing too long.
- Copying the court's words.
- Memorizing cases instead of rules.
- Waiting until the end of term to make an outline.
- Skipping practice questions.
- Weak application, which is where marks are lost.
It also helps to keep a running list of questions you could not answer after reading a case. Bring them to class or office hours, since law instructors usually appreciate specific, thoughtful questions.
The bottom line
Read cases for purpose, write short briefs in your own words, state the rule, build a topic outline and practice IRAC on many hypotheticals. Regular practice turns a mountain of cases into a clear picture of the law and a confident exam answer.
Frequently asked questions
What is a case brief?
A short summary of a court decision in your own words, usually covering the facts, procedural history, issue, holding, reasoning and any notes or dissent. It helps you find the rule and review before class and exams.
What is IRAC?
A method for answering legal problems: state the Issue, set out the Rule, Apply the rule to the facts and give a Conclusion. Variants such as CREAC are used in some courses.
How long should a case brief be?
Short enough to review quickly, often a third to a half page. If your brief is as long as the case, it is not helping you.
Should I read the whole case?
Read all of the cases assigned, but with purpose. Edited casebook extracts are shorter, and you can skim long passages of procedure once you have the main points.
How do I prepare for a law exam?
Build a clear outline of rules by topic, memorize the key rules, and practice many hypotheticals under timed conditions. Law exams reward application of rules to new facts.
