What is the highest court in the United States?

The highest court in the United States is The Supreme Court. This court is the final arbiter of federal constitutional law and has the authority to interpret the Constitution, review laws, and resolve disputes that involve state and federal laws. Established under Article III of the Constitution, The Supreme Court plays a crucial role in shaping U.S. law and ensuring that justice is administered uniformly across the country.

The Supreme Court's decisions can only be overturned by a constitutional amendment or by the Court itself overturning a previous decision, which underscores its position as the highest authority in the judicial system. In this way, it provides a checks and balances system against the legislative and executive branches of government, ensuring that laws reflect constitutional principles.
