The U.S. Supreme Court: Inside the Decision-Making Process

Each June, the nation focuses on the U.S. Supreme Court as it delivers some of its most significant decisions. Before any landmark ruling makes headlines, a structured legal process shapes it, much of which occurs away from public view. This procedure includes strict gatekeeping rules, private conferences, written briefs, oral arguments, and the eventual announcement of an opinion.

The Agenda-Setting Process

The Supreme Court is a reactive body. It waits for cases to come before it rather than seeking them out. Typically, the losing party in a lower court files a writ of certiorari to the Supreme Court, asking for a review of the case. The winning party can oppose this, arguing that the lower court decision was correct. Sometimes, interest groups submit amicus curiae briefs to indicate a case’s national importance. Such cases are more likely to be reviewed.

Recently, the court receives around 4,000 petitions per term but decides fewer than 80 cases, making the likelihood of a case being heard about 2%. To manage the petition volume, justices rely on law clerks, who are recently graduated lawyers. These clerks write memos to help justices decide whether to grant or deny each petition. Most Fridays, the justices meet in a private conference to discuss these petitions. At least four of the nine justices must agree to hear a case. Cases that receive a certiorari grant move to the merits stage, while others uphold the lower court’s decision.

Legal Briefs and Oral Arguments

During the merits stage, parties attempt to persuade the justices through legal briefs. The petitioner, arguing a legal error in lower court rulings, seeks reversal. The respondent defends the lower court’s decision. Amicus curiae briefs from various entities often highlight the public policy impacts of a case, aligning with their ideological goals. Recent terms average about 16 such briefs per case.

After briefing, oral arguments occur, typically lasting an hour and shared between petitioner and respondent. Justices question attorneys and may hint at their leaning on the case.

Conferences and Voting

Post-argument, justices gather in private to discuss and cast preliminary votes on cases. The chief justice speaks first, followed by others in seniority order. A majority forms and a justice is assigned to draft the majority opinion if they are in agreement. If not, the senior justice in the majority assigns this task.

Majority opinions undergo revisions as justices provide feedback. If a justice becomes unhappy with the draft, they might change sides. In addition to the majority opinion, justices can write concurring or dissenting opinions. Concurring opinions agree with the outcome but differ in reasoning. Dissenting opinions express disagreement with both outcome and reasoning.

Releasing Opinions

The court releases opinions publicly from October to late June or early July, with critical cases usually in June. The majority opinion author reads a summary; dissenting justices might read their opinions aloud if especially dissatisfied, signifying strong disagreement.

For instance, on June 29, 2023, Justice Sonia Sotomayor read her dissent in Students for Fair Admissions v. Harvard College. She criticized the decision as it ended affirmative action in admissions, arguing that such programs ensure racial equality per the 14th Amendment by addressing discrimination’s lingering effects.

The essential rulings each June represent months of deliberate legal processes. They inform constitutional interpretations and affect the lives of many Americans. Understanding this process demystifies the court and highlights its influence.
