The Supreme Court of the United States is the highest court in the federal judiciary and the final interpreter of the Constitution. Its decisions shape the law of the land on issues ranging from civil rights to economic regulation to the balance of power between branches of government. Understanding how the Court operates helps you follow its decisions and appreciate how they affect your rights and daily life.
Article III of the U.S. Constitution establishes the Supreme Court and gives Congress the authority to create lower federal courts. The Court's primary role is to interpret the Constitution and federal law, resolving disputes about what the law means and how it applies.
The Court's key functions include:
The Court is composed of nine justices: one Chief Justice and eight Associate Justices. Justices are appointed by the President, confirmed by the Senate, and serve lifetime appointments during "good behaviour," as stated in the Constitution. You can learn more about the current Court at supremecourt.gov.
The vast majority of cases the Supreme Court hears arrive through a process called certiorari (often shortened to "cert"). A party that loses in a lower court can petition the Supreme Court to review the decision. The Court then decides whether to take the case.
The path to the Supreme Court typically follows these steps:
The Court is most likely to grant certiorari when there is a "circuit split" (different appeals courts have reached different conclusions on the same legal question), when a case involves a significant constitutional question, or when the federal government requests review through the Solicitor General.
In a small number of cases, the Supreme Court has original jurisdiction, meaning the case can be filed directly with the Court without going through lower courts first. These cases are defined in the Constitution and include disputes between states and cases involving ambassadors.
Once the Court agrees to hear a case, it follows a structured process that unfolds over the course of the Court's term, which runs from the first Monday in October through late June or early July.
Both sides submit detailed written arguments called briefs. These legal documents present each party's interpretation of the law and the facts. Outside parties who have a stake in the outcome, such as advocacy organizations, state governments, or legal scholars, may also submit "amicus curiae" (friend of the court) briefs offering additional perspectives. Amicus briefs can be influential in shaping how the justices think about a case.
The Court hears oral arguments in the courtroom of the Supreme Court building in Washington, D.C. Each side typically receives 30 minutes to present its case. During this time, justices frequently interrupt with questions, which often signal their concerns and leanings. Oral arguments are open to the public, and audio recordings are made available on the Supreme Court's website.
After oral arguments, the justices meet in a private conference to discuss and vote on the case. No one other than the nine justices is present during conference. The Chief Justice leads the discussion, and each justice speaks in order of seniority. A simple majority (five of nine justices) is needed to decide a case.
The senior justice in the majority assigns the task of writing the majority opinion. This opinion becomes the binding law of the land. The process of writing and circulating draft opinions can take weeks or months, as justices negotiate language and occasionally change their votes.
When a vacancy occurs on the Supreme Court, whether through retirement, death, or resignation, the President nominates a replacement. The nominee must then be confirmed by the U.S. Senate. This process is outlined in the Constitution's Appointments Clause (Article II, Section 2).
How the confirmation process works:
Supreme Court nominations are often among the most consequential decisions a President makes, since justices typically serve for decades. You can contact your senators to share your views on pending nominations. Track nominees and confirmation proceedings at Congress.gov.
Supreme Court decisions set binding precedent for every court in the country. When the Court rules on a constitutional question, that interpretation becomes the supreme law of the land until the Court itself revisits the issue or the Constitution is amended. This means the Court's decisions directly shape the rights and obligations of every American.
Areas where Court decisions have direct impact:
While you cannot vote for or against Supreme Court justices directly, you can influence the composition of the Court by voting for the President who nominates them and the senators who confirm them. You can also contact your senators to express your views during the confirmation process.
