What is the highest court in the United States judicial branch?

The Supreme Court is the highest court in the United States judicial branch and serves as the final arbiter of the law. Established under Article III of the U.S. Constitution, the Supreme Court has the authority to hear cases that revolve around significant constitutional issues, federal statutes, and treaties. Its decisions set legal precedents that all lower courts must follow, making it a pivotal institution in interpreting the law and ensuring justice across the nation.

The unique role of the Supreme Court includes its ability to review and overturn decisions made by lower courts, including both appellate and district courts, and to resolve conflicts between different circuit courts. This capability underscores its position as the ultimate authority in the U.S. legal system.

Other court levels, such as district courts and appellate courts, serve important functions within the judicial branch. District courts are the trial courts where cases are initially heard, while appellate courts review decisions made by district courts. However, neither has the overarching authority or finality that the Supreme Court holds in the judicial hierarchy.
