Understanding the Decision-Making Process of the U.S. Supreme Court

Every June, the nation turns its focus to the U.S. Supreme Court’s pivotal decisions. These rulings are the result of a highly structured legal process, much of which is unseen by the public. This procedure includes strict rules, confidential conferences, written briefs, oral arguments, and the final public announcement of opinions.

The Agenda-Setting Process

The Supreme Court operates as a reactive entity. It waits for cases to be brought before it, primarily by parties who have lost in lower courts. These parties file a writ of certiorari, a legal document urging the Supreme Court to review their case. The opposing party may file a brief arguing the lower court’s decision was correct.

Interest groups often file amicus curiae briefs, indicating national importance, thereby increasing the likelihood of review. Recently, the Supreme Court receives around 4,000 petitions annually but decides less than 80 cases—approximately 2%.

To manage these petitions, justices rely on their law clerks. These young lawyers draft memos recommending the acceptance or denial of each petition. Most Fridays, justices meet privately to discuss these petitions. The court employs a ‘rule of four,’ where at least four justices must agree to review a case. Post-conference, decisions are publicly listed as granted or denied certiorari.

Legal Briefs and Oral Arguments

Parties present their cases primarily through legal briefs. Petitioners argue for reversal due to legal errors, while respondents defend the lower court’s judgment. Interest groups can submit amicus curiae briefs to highlight public policy implications, pursuing ideological goals.

On average, cases receive 16 amicus briefs, but some high-profile cases receive over 100, such as Obergefell v. Hodges. After briefing, oral arguments occur, typically lasting an hour with time split equally. Justices question attorneys, often hinting at potential decisions.

Conference and Votes

Days after oral arguments, justices reconvene privately to discuss cases and cast preliminary votes. The Chief Justice leads, followed by seniority. A majority forms during this meeting, though votes can change until the opinion is announced.

A justice in the majority drafts the majority opinion. If the Chief Justice is in the majority, they assign the opinion. If in the minority, the most senior justice in the majority assigns it.

Opinions undergo revisions, as justices negotiate and provide feedback. If a justice in the majority disagrees with the draft, they may join the minority. Besides the majority opinion, justices can write concurring and dissenting opinions.

Releasing Opinions

Opinions are released between October and late June or July, with major cases announced in June. The majority opinion author usually summarizes the opinion. Occasionally, dissenting justices may read from their opinion, signaling significant disagreement.

For example, on June 29, 2023, Justice Sonia Sotomayor read her dissent in Students for Fair Admissions v. Harvard College, criticising the decision to end affirmative action in admissions and arguing it undermines the 14th Amendment’s promise of racial equality.

These significant rulings result from a prolonged and detailed process, where petitions are filtered, cases are argued, and opinions are meticulously drafted behind closed doors. This systematic process helps demystify the Supreme Court, illustrating how nine unelected justices can profoundly influence the Constitution’s interpretation and impact Americans’ lives.
