The Supreme Court of the United States is the largest court in the governmental tribunal of the United States. Instituted pursuant to Article III of the U.S. Constitution in 1789, it has fundamental control over a small range of cases, such as actions between two or more states, and those affecting ministers. It also has ultimate and largely changeable authority over all federal court and state court trials which include a point of constitutional or statutory law.
