What is the highest court in the United States?

The U.S. Supreme Court is the highest court in the United States, holding the ultimate authority in interpreting federal law and the Constitution. Established in Article III of the Constitution, the Supreme Court has the power to review decisions made by lower courts, including both District Courts and Courts of Appeals. It also has the authority to resolve conflicts among different jurisdictions and can strike down laws or executive actions deemed unconstitutional.

The significance of the Supreme Court also lies in its role in safeguarding civil liberties and rights, as many landmark decisions have shaped American law and society. It is the final arbiter on legal disputes, making its interpretations of the law binding across the entire country. This distinguishes it from both the U.S. District Courts, which are trial courts handling federal cases, and the U.S. Court of Appeals, which serves as an intermediate appellate court. The term "Federal Court" is too vague as it encompasses all courts under the federal judiciary, including the Supreme Court, but does not specifically indicate the highest authority.
