What is the highest court in the United States?

The highest court in the United States is the Supreme Court. This court serves as the final arbiter of the law, interpreting the Constitution and federal laws. It holds the ultimate authority on legal disputes and its decisions set precedents that guide the legal framework of the entire nation. The Supreme Court's rulings can only be overturned by a subsequent act of the court itself or a constitutional amendment, highlighting its prominent role in the judicial system.

Circuit Courts, Appellate Courts, and District Courts are important within the federal and state judicial structures, serving various functions such as hearing cases at different levels and providing appeals, but none of these courts has the same level of authority or the final say on matters of constitutional interpretation that the Supreme Court possesses.
