Find clear answers to common questions about the U.S. Supreme Court, its history, and its role in the American legal system.
The Supreme Court is the highest court in the federal judiciary. Its primary role is to interpret the Constitution and federal law, ensuring a uniform application across the country. It acts as the final arbiter on legal disputes and has the power of judicial review to determine the constitutionality of laws and executive actions.
Justices are nominated by the President of the United States and must be confirmed by a majority vote in the Senate. They serve for life, barring resignation, retirement, or impeachment, to ensure judicial independence from political pressures.
Landmark cases establish major precedents that reshape American law and society. Brown v. Board of Education (1954) declared racial segregation in public schools unconstitutional, overturning the "separate but equal" doctrine and becoming a cornerstone of the Civil Rights Movement.
Most cases reach the Court via a writ of certiorari, a request for the Court to review a lower court's decision. The Court grants certiorari for only a small fraction of petitions, typically when a case involves a significant federal question, a conflict between circuit courts, or an issue of national importance.
The majority opinion represents the Court's official decision and reasoning, agreed upon by at least five Justices. A concurring opinion agrees with the judgment but offers different reasoning. A dissenting opinion disagrees with the majority's decision and explains why.
