Supreme Court of the United States (SCOTUS)

The Supreme Court of the United States (SCOTUS) is the highest judicial authority in the federal system and the ultimate arbiter of the Constitution, federal statutes, and treaties. Established under Article III of the U.S. Constitution, it embodies the judicial power of the United States and ensures the uniform interpretation and application of federal law across all jurisdictions. The Court is composed of nine Justices—one Chief Justice and eight Associate Justices—appointed by the President with the advice and consent of the Senate, serving life tenure during good behavior to preserve independence from political influence. SCOTUS possesses both original jurisdiction, narrowly defined by the Constitution to include cases affecting ambassadors, other public ministers and consuls, and disputes in which a state is a party, and appellate jurisdiction, which forms the bulk of its caseload, encompassing review of decisions from federal courts of appeals and state supreme courts on issues of federal law or constitutional interpretation. Through the power of judicial review, formally recognized in Marbury v. Madison (1803), the Court has the authority to invalidate legislative and executive actions inconsistent with the Constitution. Its decisions are binding on all lower courts, both federal and state, establishing precedent that shapes the trajectory of American law. As the final guardian of constitutional meaning and individual rights within the United States legal system, the Supreme Court functions as the cornerstone of the doctrine of separation of powers, ensuring accountability among the branches of government and safeguarding the rule of law.
