The highest court in the United States is the Supreme Court. Established under Article III of the U.S. Constitution, the Supreme Court has ultimate jurisdiction over all federal and state court cases that involve a point of constitutional or federal law. This authority includes the power to interpret the Constitution and to review decisions made by lower courts.

The Supreme Court consists of nine justices, including a Chief Justice, and is responsible for making decisions that can have widespread implications on law and society. Its rulings set precedents that lower courts are obliged to follow and serve to shape the interpretation of laws as well as the Constitution itself for generations. In this context, recognizing the role of the Supreme Court as the final arbiter of legal disputes highlights its significance in the American judicial system, distinguishing it from other courts such as the District Courts, Circuit Courts, and Courts of Appeals, which serve different functions within the judiciary.
