How the Supreme Court Chooses and Decides Cases

The Supreme Court usually chooses cases through discretionary certiorari review, then decides the legal question through briefing, argument, deliberation and an announced disposition. Keep the stages separate: a vote to hear a case is not a vote that either party should win. Read the opinion and judgment for the eventual answer.

Start with a Petition for Review

Thousands of litigants want Supreme Court review, but the Court hears only a small fraction. A party ordinarily begins discretionary review by filing a petition for a writ of certiorari. The petition asks the Court to call up the lower-court record and decide the case. Certiorari is not a second trial, an order requiring an official to perform a duty, or a declaration that the lower court was wrong.

Distinguish the Petition from Merits Briefing

The petition identifies the question presented, explains the procedural history, and argues why the issue deserves the Court’s limited attention. The opposing party can file a response, and amici sometimes urge a grant or denial. The justices and their staff review the materials before the Court votes. If certiorari is granted, the case moves to full merits briefing and often oral argument. The grant itself does not resolve the legal question.

Identify Reasons for Selecting a Case

The Court is especially likely to consider conflicts among federal courts of appeals or state courts on an important federal question, significant departures from accepted law, and questions of broad national importance. Error correction can matter, but the Court is not organized to correct every mistaken judgment. A denial of certiorari leaves the lower judgment intact and carries no implication that the justices approve its reasoning.

Ask Whether This Case Presents the Issue Clearly

A suitable vehicle matters as well. The Court may decline an important question if the record is unclear, the issue was not preserved, another ground could decide the case, or later events make review impractical. The justices often wait for additional lower courts to examine a new issue before choosing a case. Docket selection therefore considers both the legal question and whether this particular case can resolve it cleanly.

Compare a Circuit Conflict with a Factual Complaint

Hypothetical comparison. Two circuits interpret the same federal statute differently, so identical conduct is lawful in one region and unlawful in another. A petition emphasizing that conflict presents a reason for national resolution. A petition arguing only that one jury misunderstood one witness usually presents a weaker institutional reason for review.

The word “appeal” can mislead beginners. A litigant may ask for Supreme Court review, but certiorari is ordinarily discretionary rather than an appeal of right. Look for a petition, a circuit conflict, a nationally significant federal question, and the Court’s choice whether to hear the case.

Follow the Rules, Proceedings and Opinion Labels

Supreme Court Rule 10 describes compelling reasons for discretionary review, including important conflicts among appellate courts. Its considerations guide rather than exhaust discretion. A claimed factual error or misapplication of an otherwise correct legal rule is rarely enough.

The U.S. Courts procedures guide explains the rule of four for accepting a case. After merits briefing and argument, the justices confer, vote and circulate draft opinions. The Chief Justice assigns the Court’s opinion when in the majority; otherwise, the senior justice in that majority makes the assignment. Drafting can change the alignment before release.

The Court’s own procedures overview describes review on an existing record and written briefs, rather than a new jury trial with witnesses. Oral argument lets the justices question legal positions; the grant of review does not establish the answer.

Use the Court’s guide to opinions to distinguish the majority or principal opinion from separate concurrences and dissents. A concurrence may agree with the outcome while explaining a different rationale. A dissent is not the Court’s holding. A per curiam opinion does not name an author and can resolve a case without oral argument, so this lesson’s usual argued-case sequence is not universal.

Separate Granting Review from Deciding the Merits

In a hypothetical case, four justices vote to grant a petition presenting an important conflict between two circuits. A commentator says that the grant proves the lower court was wrong. What stage has actually been completed, and what still needs to happen?
