# Per Curiam Opinion — AP Gov Definition & Exam Guide

## Definition

A per curiam opinion is a short, unsigned decision issued by the Supreme Court that announces the Court's judgment 'by the court' as a whole, without a named author or extended reasoning, typically used for clear-cut or procedural cases.

## What It Is

A per curiam opinion (Latin for "by the court") is a [Supreme Court](/ap-gov/key-terms/supreme-court "fv-autolink") decision with no named author. Instead of one justice writing a long, signed majority opinion, the Court speaks as a single institutional voice in a brief, unsigned ruling. The Court usually uses this format when a case is straightforward, procedural, or so clearly controlled by existing precedent that a full opinion would be overkill.

Don't let "brief and unsigned" fool you. A per curiam opinion is still a real exercise of judicial power under [Article III](/ap-gov/unit-2/judicial-branch/study-guide/y7kYkIyrT8DYX1Ud7Y75 "fv-autolink"). It resolves the dispute, binds the parties, and counts as precedent. The most famous example is *Bush v. Gore* (2000), where the Court issued a per curiam opinion that effectively decided a [presidential election](/ap-gov/unit-5/congressional-elections/study-guide/mvTrUNa6fFD9Gt98lbnc "fv-autolink"). That's a reminder that the format says nothing about the stakes.

## Why It Matters

This term lives in **Topic 2.10, The Court in Action** ([Unit 2](/ap-gov/unit-2 "fv-autolink"): Interactions Among Branches of Government). It connects directly to learning objective [AP Gov](/ap-gov "fv-autolink") 2.10.A, which asks you to explain how life tenure can lead to debate about the Supreme Court's power. Because justices serve for life, the Court can act independently of public opinion, and a per curiam opinion is the most institutional version of that independence. There's no individual justice to credit or blame, just "the Court." When an unsigned opinion decides something controversial (again, think *Bush v. Gore*), critics argue the justices are hiding behind anonymity while wielding enormous power. That tension between judicial independence and accountability is exactly what 2.10 wants you to be able to argue about.

## Connections

### Majority, Concurring, and Dissenting Opinions (Unit 2)

These are the per curiam's siblings in the family of Court opinions. A [majority opinion](/ap-gov/key-terms/majority-opinion "fv-autolink") is signed by its author and lays out full reasoning; concurrences and dissents let individual justices speak for themselves. A per curiam strips all of that away. No author, minimal reasoning, one collective voice. Justices can still write separate dissents from a per curiam ruling, though.

### Judicial Precedent and Stare Decisis (Unit 2)

Per curiam opinions are often used precisely because [precedent](/ap-gov/key-terms/precedent "fv-autolink") already settles the question. The Court is essentially saying "existing case law answers this, no essay needed." And the ruling itself becomes binding precedent, even without a signature attached.

### Life Tenure and Judicial Independence (Unit 2)

[Life tenure](/ap-gov/key-terms/life-tenure "fv-autolink") lets justices rule without worrying about reelection, which is how the Court can issue unpopular decisions. An unsigned per curiam opinion pushes that insulation one step further, because the public can't even attribute the decision to specific justices. That fuels the debate about Court power that LO 2.10.A asks you to explain.

### [Brown v. Board of Education (Unit 3)](/ap-gov/key-terms/brown-v-board-of-education)

Useful contrast. Brown was a signed, unanimous opinion authored by Chief Justice Warren, because the Court wanted maximum moral authority behind desegregation. When the Court wants to project strength, it signs its name. When it wants speed or low profile, per curiam is the tool.

## On the AP Exam

Per curiam opinion shows up most often as a vocabulary-level multiple-choice item, usually asking you to match opinion types (majority, concurring, dissenting, per curiam) to their definitions. The trap answers count on you forgetting that per curiam means unsigned and collective. No released FRQ has required this term verbatim, but it's fair game in a SCOTUS Comparison FRQ or an Argument Essay about judicial power, where naming the type of opinion a Court issued (like the per curiam in Bush v. Gore) shows command of how the Court actually operates. Your main job is simple: define it correctly and distinguish it from a signed majority opinion.

## per curiam opinion vs Majority opinion

Both speak for the Court and both create binding precedent, so the confusion is understandable. The difference is authorship and depth. A majority opinion is signed by the justice who wrote it and explains the Court's reasoning in full, which guides lower courts in future cases. A per curiam opinion is unsigned, issued in the name of the whole Court, and usually short on reasoning because the case is procedural or already settled by precedent. Quick check: if you can name who wrote it, it's not per curiam.

## Key Takeaways

- A per curiam opinion is a brief, unsigned Supreme Court decision issued in the name of the entire Court rather than a named author.
- The Court typically uses per curiam opinions for clear-cut or procedural cases where existing precedent already answers the question.
- Despite being short and unsigned, a per curiam opinion is fully binding and counts as precedent, just like a signed majority opinion.
- Justices can still write dissenting or concurring opinions alongside a per curiam ruling, so unsigned does not mean unanimous.
- Bush v. Gore (2000) was a per curiam opinion, proving the format can carry enormous political consequences.
- For LO 2.10.A, per curiam opinions feed the debate over Court power because anonymity plus life tenure means controversial rulings come with very little individual accountability.

## FAQs

### What is a per curiam opinion in AP Gov?

It's a short, unsigned Supreme Court decision issued "by the court" as a whole rather than authored by a named justice. The Court uses it mostly for clear-cut or procedural cases, and it still creates binding precedent.

### Is a per curiam opinion always unanimous?

No. Per curiam means unsigned, not unanimous. Justices can and do write dissents from per curiam rulings. Bush v. Gore (2000) was per curiam and had four justices writing in dissent.

### How is a per curiam opinion different from a majority opinion?

A majority opinion is signed by its author and explains the Court's reasoning in detail, while a per curiam opinion is unsigned, brief, and issued in the name of the whole Court. Both are equally binding on the parties and lower courts.

### Does a per curiam opinion count as precedent?

Yes. Even though it's brief and unsigned, a per curiam opinion is an official Article III judgment of the Supreme Court, so it binds the parties and serves as precedent for the dispute it resolves.

### Why would the Supreme Court issue an unsigned opinion?

Usually because the case is procedural or already controlled by precedent, so a full opinion isn't needed. Critics also note that anonymity can shield justices from individual accountability on controversial rulings, which connects to the debate over judicial power in Topic 2.10.
