The Judiciary Act of 1789 provided for a Supreme Court made up of a Chief Justice and five associate justices is a true statement. This was written in Article III which defines much of the judiciary's position in the American government. It explicitly states that "judicial power of the United States shall be vested in one Supreme Court and such inferior courts" so the Supreme Court is the only court recognized by the Constitution, with one Chief justice and five associate justices.
