What is the highest court in the United States?

The Supreme Court is the highest court in the United States, holding ultimate appellate jurisdiction over all federal and state court cases involving issues of federal law. Established under Article III of the U.S. Constitution, it serves as the final arbiter on constitutional interpretation and has the authority to review decisions made by lower courts. The Supreme Court's decisions set precedents that guide future case law, influencing not only the interpretation of the law but also shaping policy and societal standards.

The other courts mentioned, such as the Court of Appeals and the District Court, are part of the federal judiciary system but are subordinate to the Supreme Court. The Court of Appeals handles appeals from District Courts, while the District Courts are the general trial courts. The International Court, primarily concerned with international disputes and not part of the U.S. legal system, is distinct and does not hold jurisdiction over U.S. domestic legal matters. This structure emphasizes the central role of the Supreme Court in interpreting and upholding the Constitution.
