What is the highest court in the United States?

The highest court in the United States is the Supreme Court. This court has ultimate appellate jurisdiction over all federal and state court cases that involve a point of constitutional or federal law, meaning it serves as the final arbiter on issues of interpretation of the Constitution and federal laws. The Supreme Court's decisions set important precedents that lower courts must follow, making it the most authoritative judicial body in the country.

The Federal Court system includes numerous other courts, such as Circuit Courts and District Courts; however, these courts do not hold the same level of authority as the Supreme Court. Circuit Courts generally serve as appellate courts for cases from the District Courts, while District Courts are trial courts that handle various types of cases. Therefore, while these courts are essential components of the judicial system, they operate under the supremacy of the Supreme Court, which can review their decisions.
