The Supreme Court is the highest court in the United States and holds ultimate judicial authority over federal and state court cases involving issues of federal law. It is comprised of justices appointed by the President and confirmed by the Senate. The Supreme Court has the power to interpret the Constitution, ensuring that federal laws and decisions align with its principles. This is why it has a critical role in the American legal system, serving as the final arbiter of legal disputes and constitutional questions.

Other courts, such as the District Courts and Courts of Appeals, function at lower levels within the judicial hierarchy. District Courts serve as trial courts for federal cases, while Courts of Appeals review decisions made by District Courts, but neither has the same level of authority or final say in legal matters as the Supreme Court. The Circuit Court does not even exist as a federal court designation, which further underscores the Supreme Court’s position as the pinnacle of the U.S. judicial system.
