What is the highest court in the United States?

The Supreme Court holds the title as the highest court in the United States, serving as the final arbiter of federal constitutional law. Established under Article III of the Constitution, it has the authority to interpret laws and evaluate their compliance with the Constitution. This court's decisions set legal precedents that must be followed by all lower courts, providing a uniform interpretation of the law across the nation.

The other courts mentioned have specific roles and limitations. The Court of Appeals acts as an intermediary appellate court, reviewing decisions made by lower courts, but it does not have the ultimate authority. The District Court is the trial-level court where federal cases are initially heard, which means its jurisdiction is restricted to first-instance cases, and it also does not serve as the supreme authority. Family Court specializes in matters such as divorce and child custody on a state level and has no jurisdiction in federal matters, further distinguishing it from the Supreme Court's broader constitutional and federal judicial responsibilities.
