What is the highest court in the United States?

The Supreme Court is the highest court in the United States, and it serves as the ultimate appellate court in the federal judiciary system. It has the authority to interpret the Constitution, review laws, and decide cases involving federal law as well as disputes between states. The decisions made by the Supreme Court set precedents that are binding on all lower courts, meaning that its rulings significantly influence American law and society.

The Supreme Court is composed of nine justices who are appointed for life, ensuring continuity and stability in legal interpretations. It is also the only court established directly by the Constitution, which underscores its foundational role in the American legal system. This makes it more significant than other courts, such as federal courts, district courts, or circuit courts, each of which serves specific functions within the judicial hierarchy but cannot overturn the decisions made by the Supreme Court.
