Which court is the highest in the United States?

The Supreme Court is the highest court in the United States, holding the ultimate authority on legal interpretation and constitutional issues. It serves as the final arbiter in judicial matters and has the power to review and overturn decisions made by lower courts, including Circuit Courts and Courts of Appeals. The Supreme Court's responsibilities include hearing cases that involve significant questions about federal law or the Constitution. Its decisions can lead to major shifts in legal precedent and policy.

The other courts listed serve specific functions within the judicial system but do not have the same level of authority or responsibility as the Supreme Court. Circuit Courts typically handle a variety of cases at the state level and often serve as trial courts, while District Courts also deal with cases but are generally the trial courts for federal cases. Courts of Appeals review decisions made by lower courts but do not have the final say on legal interpretations; that responsibility lies with the Supreme Court.
