Detail:

The Judiciary branch of government is established by Article III of the United States Constitution, which opens with these words:  "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."The Constitution doesn't say how many justices should be on the Supreme Court.  The number varied somewhat in the earlier years of US history.  Since 1869, the number has been settled at 9 justices (when all Supreme Court seats are filled).District courts, US courts of appeal (also known as circuit courts), and the Supreme Court are the three-tiered system of federal courts for criminal cases and for civil cases that pertain to the United States Constitution or federal statutes.  There are 12 circuits into which the district courts are organized, and each circuit has its own Court of Appeals.  There's also actually a 13th Court of Appeals that was created in 1982, the United States Court of Appeals for the Federal Circuit.  That court is in Washington DC, and hears appeals regarding cases dealing with things like patent law and veterans claims.
