The country has a
bicameral legislature and a political party system, based on universal adult suffrage and fair elections. The
Senate has 21 members, appointed by the President, 12 on the advice of the Prime Minister, two on the advice of the Leader of the Opposition, and seven at the President's discretion. The
House of Assembly has 30 members, all elected. Both houses debate all legislation. However, the House of Assembly may override the Senate's rejection of bills, except those amending the
Constitution. Officers of each house (President and Deputy President of the Senate; Speaker, Deputy Speaker, and Chairman of Committees of the Assembly) are elected from the members of the respective houses. In keeping with the
Westminster system of governance, Barbados has evolved into an independent
parliamentary democracy, meaning that all political power rests with Parliament under a non-political President as head of state. Executive authority is vested in the
President, who normally acts only on the advice of the
Prime Minister and
Cabinet, who are collectively responsible to Parliament. Barbadian law is rooted in
English common law, and the
Constitution of Barbados, implemented in 1966, is the supreme
law of the land. Fundamental rights and freedoms of the individual are set out in the Constitution and are protected by a strict legal code. The Cabinet is headed by the Prime Minister, who must be an elected member of Parliament. Other ministers are appointed from either chamber by the President, as advised by the Prime Minister. The President appoints as Leader of the Opposition the member of the House of Assembly who commands the support of the largest number of members of that House in opposition to the ruling party's government. The maximum duration of a Parliament is five years from the first sitting. There is a simultaneous dissolution of both Houses of Parliament by the President, acting on the advice of the Prime Minister. There is an established non-political
civil service. Also, there are separate constitutional commissions for the Judicial and Legal Service, the Public Service, and the Police Service. ==History==
