Inside the U.S. Supreme Court’s Decision-Making Process

Each June, the nation closely observes the U.S. Supreme Court as it delivers some of its most impactful rulings. Before these landmark decisions hit the headlines, they are crafted through a detailed legal process that largely occurs out of public view.

The Legal Journey

The Supreme Court’s procedures involve strict guidelines. The process begins with gatekeeping rules, private conferences, written briefs, and oral arguments, culminating in the announcement of an opinion.

As a Supreme Court scholar, understanding how the court formulates policy requires insight into these regulated routines.

The Agenda-Setting Process

The Supreme Court is reactive. Only after cases are brought by individuals, businesses, or government entities does it decide on rulings. A losing party often files a writ of certiorari, arguing why the case deserves review. The winning party might oppose, stating the lower court was correct. Interest groups can also file amicus curiae briefs to highlight the significance of a case, increasing the chances of review.

Each term, the court receives approximately 4,000 petitions. Only less than 80 cases are heard, making the selection rate around 2%. To manage the volume, justices rely on law clerks who draft memos recommending whether to accept or deny petitions.

Friday Conferences

On most Fridays, justices meet privately to discuss petitions. At these conferences, four out of nine votes are needed to agree to hear a case. Following the conference, the court shares cases granted and denied certiorari.

Legal Briefs and Oral Arguments

Once certiorari is granted, the parties submit arguments through legal briefs. The petitioner seeks overturning a lower court’s error, while the respondent argues to uphold the decision. Additional amicus briefs can highlight public policy implications, with recent cases averaging about 16 briefs per case.

Oral arguments usually last an hour, split between petitioner and respondent. Justices use these arguments to probe attorneys and usually signal potential votes.

Conference and Votes

After oral arguments, justices privately discuss cases and cast preliminary votes. The chief justice speaks first, followed by others in seniority order. A justice in the majority drafts the opinion. If the chief is in the majority, they make the assignment, otherwise the most senior justice does.

Majority opinions undergo revisions through feedback among justices. Concurring opinions offer different legal bases for decisions, while dissenting ones express disagreement with rulings.

Releasing Opinions

The court releases its opinions from October to late June or early July. The author of the majority opinion often reads a summary publicly, while on rare occasions dissenting opinions are read to emphasize disagreement.

For example, Justice Sotomayor expressed discontent on June 29, 2023, in her dissent in Students for Fair Admissions v. Harvard College, opposing the decision that impacts affirmative action.

These significant rulings are products of thorough legal processes, where few cases are argued and numerous opinions are crafted. The complexities of this process reveal how the Supreme Court shapes constitutional meaning and profoundly affects American lives.
