Supreme Court of the United States
The Supreme Court of the United States is the highest federal court. Although it was explicitly recognized in Article III of the Constitution, it was not formally established until passage of the Judiciary Act of 1789 (1 Stat. 73) and was not organized until 1790. Though its size and jurisdiction have changed over time, the Supreme Court has fulfilled its two main functions: acting as the final interpreter of state and federal law and establishing procedural rules for the federal courts.
