What is the highest court in the United States?

The Supreme Court is recognized as the highest court in the United States, serving as the final arbiter of legal disputes under federal law and the Constitution. Established in 1789, the Supreme Court has the authority to review cases and rulings from lower courts, interpret laws, and ensure that legislative and executive actions comply with the Constitution. Its decisions set precedents that guide the legal framework of the country, making it the ultimate authority in matters of Constitutional interpretation.

The other courts mentioned serve different functions within the judicial system. The Court of Appeals hears appeals from lower courts but does not have the same level of authority as the Supreme Court. The District Court is where federal cases begin, handling trials and initial proceedings. The International Court, while significant in the realm of international law, does not have jurisdiction over domestic U.S. legal matters. This structure underscores the Supreme Court's unique position as the pinnacle of the U.S. judiciary.
