Understanding Court Opinions
How to read and make sense of Supreme Court decisions — majority opinions, dissents, concurrences, and what they mean for the law.
Supreme Court opinions can be dozens or even hundreds of pages long, filled with legal jargon. Here's a guide to understanding what you're reading.
The Structure of an Opinion
A typical Supreme Court opinion includes:
1. **Syllabus**: A summary written by the Court's Reporter of Decisions (not the justices). This is a helpful overview but is not officially part of the ruling. 2. **Majority Opinion**: The binding legal ruling, explaining the Court's reasoning and decision. 3. **Concurrences**: Opinions by justices who agree with the result but want to add or emphasize different reasoning. 4. **Dissents**: Opinions by justices who disagree, explaining why they believe the majority got it wrong.
What's Binding?
Only the majority opinion is binding law. Concurrences and dissents express individual justices' views but do not create legal rules. However, concurrences can influence future decisions, and dissents sometimes become the basis for overturning precedent years later.
Key Terms to Know
- Affirmed: The Court agrees with the lower court's decision
- Reversed: The Court disagrees and overturns the lower court
- Vacated: The Court erases the lower court's decision
- Remanded: The Court sends the case back to the lower court for further proceedings
- Per Curiam: An unsigned opinion representing the whole Court
- Plurality: When no single opinion gets five votes, the opinion with the most votes controls but has less precedential weight
- Stare Decisis: The principle that courts should follow their own previous decisions
Reading Tips
When reading a Supreme Court opinion, start with the syllabus for an overview. Then read the majority opinion's first and last few paragraphs to understand the question presented and the Court's answer. Pay attention to the vote count — a 9-0 decision carries more weight than a 5-4 split.
The Power of Dissents
Some of the most famous passages in Supreme Court history come from dissenting opinions. Justice Harlan's dissent in Plessy v. Ferguson ("Our Constitution is colorblind") eventually became the law in Brown v. Board of Education. Today's dissent may be tomorrow's majority opinion.
