Luxembourg - Government
Luxembourg is a constitutional monarchy, governed by the constitution of 1868 as revised in 1919 (when universal suffrage and proportional representation were introduced) and subsequently. The grand ducal crown is hereditary in the house of Nassau-Weilbourg. Legislative power is vested in the Chamber of Deputies, the 60 (prior to 1984, 64 members) members of which are elected for five-year terms. In addition, the Council of State, composed of 21 members appointed for life by the sovereign, acts as a consulting body in legislative, administrative, and judicial matters and has the right of suspensive veto.
Executive power rests jointly in the sovereign, who may initiate legislation, and a prime minister (president of the government), appointed by the monarch, who in turn selects a cabinet. The prime minister, together with the cabinet, must command a majority in the Chamber of Deputies. Voting is compulsory, and eligibility begins at age 18.
