The Parliament of Montenegro (Skupština Crne Gore / Скупштина Црне Горе) is the unicameral legislature of Montenegro. The Parliament currently has 81 members, with each member elected to a four-year term. Following the 2006 independence referendum, the Parliament declared and ratified the independence of Montenegro on 3 June 2006. Members of the Parliament are elected using proportional representation. The Parliament of Montenegro was initially established by the Constitution of the Principality of Montenegro in 1905 and was called the Popular Assembly (Narodna skupština). It had a limited legislative role, limited by the authority of the Knjaz (Prince). The first parliament was constituted in 1906. Following the incorporation of the Kingdom of Montenegro into the Kingdom of Yugoslavia in 1918, the Parliament of Montenegro was disbanded until World War II. The Parliament was reinstated in 1944, in the form of the Montenegrin Anti-Fascist Assembly of National Liberation (CASNO), which changed its name to the Montenegrin National Assembly, and later the National Assembly. This lasted until 1946, when a new Assembly was elected for the Socialist Republic of Montenegro, a constituent republic within the SFR Yugoslavia. The current parliament is the 23rd since the foundation of the Parliament. The Parliament appoints the Prime Minister nominated by the President, as well as the ministers chosen by the Prime Minister. Parliament also passes all laws in Montenegro, ratifies international treaties, appoints justices of all courts, adopts the budget and performs other duties as established by the Constitution. The Parliament can pass a vote of no-confidence in the Government with a majority of the members. A deputy has a four-year term. One deputy is elected per 6,000 voters, which in turn results in a change of total number of deputies in the parliament. Current assembly convening comprises 81 deputies. The Parliament has 81 members (deputies) elected by a D'Hondt method system of proportional representation for a four-year term.
