The federal government exercises control over the central government and is divided into three independent branches: executive, legislative and judicial. Executive power is exercised by the President, advised by a cabinet. Legislative power is vested upon the National Congress, a two-chamber legislature comprising the Federal Senate and the Chamber of Deputies. Judicial power is exercised by the judiciary, consisting of the Supreme Federal Court, the Superior Court of Justice and other Superior Courts, the National Justice Council and the Regional Federal Courts.
