The judicial branch is made up of the Supreme Court, Lower Courts, Special Courts, and court support organizations.
Article III, §1, of the Constitution provides that "[t]he 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." The Supreme Court of the United States was created in accordance with this provision and by authority of the Judiciary Act of September 24, 1789 (1 Stat. 73). It was organized on February 2, 1790.
