Answer:
Article III of the Constitution establishes and empowers the judicial branch of the national government. The very first sentence of Article III says: “The judicial power of the United States, shall be vested in one Supreme Court, and in such inferior courts as the Congress may from time to time ordain and establish.” So the Constitution itself says that we will have a Supreme Court, and that this Court is separate from both the legislature (Congress) and the executive (the President). It is up to Congress to decide what other federal courts we will have. But one of the first things Congress did in 1789, the year the new government got going, was to set up a federal judiciary, including the Supreme Court—with six Justices. Today, we have a three-level federal court system—trial courts, courts of appeals, and the Supreme Court—with about 800 federal judges. All those judges, and the Justices of the Supreme Court, are appointed by the President and confirmed by the Senate.
