Government and politics

The Brazilian Federation is the "indissoluble union" of three distinct political entities: the States, the Municipalities and the Federal District. The Union, the states and the Federal District, and the municipalities, are the "spheres of government". The Federation is set on five fundamental principles: sovereignty, citizenship, dignity of human beings, the social values of labour and freedom of enterprise, and political pluralism. The classic tripartite branches of government (executive, legislative, and judicial under the checks and balances system), is formally established by the Constitution. The executive and legislative are organized independently in all three spheres of government, while the judiciary is organized only at the federal and state/Federal District spheres.

All members of the executive and legislative branches are directly elected. Judges and other judicial officials are appointed after passing entry exams. Voting is compulsory for the literate between 18 and 70 years old and optional for illiterates and those between 16 and 18 or beyond 70. Together with several smaller parties, four political parties stand out: Workers' Party (PT), Brazilian Social Democracy Party (PSDB), Brazilian Democratic Movement Party , and Democrats (DEM). Almost all governmental and administrative functions are exercised by authorities and agencies affiliated to the Executive.

The form of government is that of a democratic republic, with a presidential system. The president is both head of state and head of government of the Union and is elected for a four-year term, with the possibility of re-election for a second successive term. The current president is Luiz Inácio Lula da Silva who was elected on October 27, 2002, and re-elected on October 29, 2006. The President appoints the Ministers of State, who assist in government. Legislative houses in each political entity are the main source of law in Brazil. The National Congress is the Federation's bicameral legislature, consisting of the Chamber of Deputies and the Federal Senate. Judiciary authorities exercise jurisdictional duties almost exclusively.
