What is the highest court in the United States?

The Supreme Court is the highest court in the United States, serving as the ultimate appellate court in the federal judicial system. Its primary function is to interpret the Constitution and to oversee cases that involve significant federal legal issues or conflicts between state and federal laws. The Supreme Court has the authority to make final decisions on legal interpretations, thus setting precedents that influence the interpretation of laws nationwide.

In contrast, the District Courts are the general trial courts of the federal court system, handling the bulk of federal cases, but they do not have the authority to set national precedents like the Supreme Court does. The Court of Appeals serves as an intermediary, reviewing decisions made by the District Courts, but it ultimately reports to the Supreme Court for final interpretation. The term "Federal Court" is more generic and encompasses both District Courts and Court of Appeals, but it does not specifically identify the highest level within the federal system. Therefore, the Supreme Court stands as the definitive authority in the U.S. legal system.
