What is the highest court in the United States?

The Supreme Court is the highest court in the United States and serves as the ultimate authority in interpreting the Constitution and federal law. Established under Article III of the U.S. Constitution, its decisions set precedents that guide lower courts across the country. It has the power to hear cases involving significant constitutional questions, disputes between states, and appeals from lower courts. Its ability to review the constitutionality of laws and governmental actions highlights its critical role in maintaining the rule of law and protecting individual rights.

In contrast, the District Court, Circuit Court, and Appeals Court refer to lower levels of the federal and state court systems. District Courts serve as the trial courts where cases are initially filed and heard, while Circuit Courts may refer to both trial and appellate courts depending on the context. Appeals Courts, as their name implies, review decisions made by lower courts but do not have the authority to set binding legal precedents on the level of the Supreme Court. Hence, the Supreme Court's status as the highest court is uniquely defined by its precedence, authority, and constitutional basis.
