Law students prepare for class by writing a case brief: a one-page summary of an opinion in a fixed form. (It is not the same as the long "brief" a lawyer files with a court.) Once you know the parts of an opinion, briefing is a way of pulling out the parts that matter.
Key idea
| Heading | What to write |
|---|---|
| Facts | only the facts the court relied on, in a few sentences |
| Procedural history | what the lower courts did and how the case got here |
| Issue | the legal question, as a yes-or-no question tied to the facts |
| Holding | the answer to the issue, as a rule ("Yes; a plaintiff who…") |
| Reasoning | why the court decided as it did: the rule's source and how it applied |
| Disposition | affirmed, reversed, vacated, remanded |
| Separate opinions | the main point of any concurrence or dissent |
Why it works
Worked example: Write the issue
- Make it a yes-or-no question.
- Tie it to the key facts: members who visited habitats abroad and hoped to return someday.
- Name the legal standard: injury in fact under Article III.
Answer: Do members of a group who once visited endangered species' habitats abroad and intend to return "someday" suffer an injury in fact that gives them standing under Article III?
Worked example: Match the holding
- Answer the question directly.
- Keep the key facts and the rule.
Answer: No. Vague "someday" intentions to return, without concrete plans, do not show an actual or imminent injury, so the plaintiffs lacked standing.
