What is the highest court in the United States?

The Supreme Court is the highest court in the United States, serving as the ultimate arbiter of federal constitutional law. It has the authority to interpret the Constitution, adjudicate disputes regarding federal laws, and resolve conflicts between state and federal laws. The decisions made by the Supreme Court can only be overturned by a subsequent Supreme Court decision or constitutional amendment, establishing its status as the final court of appeal in the country.

This court's power includes reviewing cases that have significant legal or constitutional implications, which means its rulings set precedence that lower courts must follow. The prominence and authority of the Supreme Court also highlight its role in safeguarding civil rights and liberties by reviewing laws and executive actions that may conflict with the Constitution.

In contrast, the other courts listed do not hold the same level of authority. District Courts are the general trial courts, Circuit Courts typically refer to appellate courts in some jurisdictions but do not operate at the same level as the Supreme Court, and the Court of Appeals handles appeals from lower courts, but all such decisions can be reviewed by the Supreme Court. Therefore, the Supreme Court holds the highest judicial power in the United States.
