What is the highest federal court in the United States?

The Supreme Court is the highest federal court in the United States and serves as the ultimate authority on constitutional matters, federal laws, and disputes between states. Established by the Constitution, it has the power to interpret laws and their applicability, shaping the legal landscape of the country. The Supreme Court's decisions set binding precedents for all lower courts, ensuring a uniform interpretation of laws across the nation. Its role in reviewing cases of significant legal importance, including those involving constitutional rights and government powers, underscores its distinction as the apex of the judicial system.

The other courts mentioned, such as the Court of Appeals, Circuit Court, and District Court, serve different functions within the federal judiciary and operate below the Supreme Court in the hierarchy. While they handle specific types of appeals and cases, none carry the authority or jurisdiction that the Supreme Court holds.
