What is the highest court in the United States?

The Supreme Court is the highest court in the United States, serving as the final arbiter of federal constitutional questions and the highest state court issues that involve federal law. It is established under Article III of the U.S. Constitution and has the authority to interpret the Constitution, assess the constitutionality of laws, and resolve disputes between states. With its power of judicial review, the Supreme Court can overturn lower court decisions and legislative acts that it finds unconstitutional, solidifying its role as the ultimate legal authority in the country.

Other courts, like the Circuit Court, Superior Court, and District Court, serve different functions within the judicial system, focusing on various types of cases and appeals, but none hold the authoritative power that the Supreme Court possesses.
