June 2007. At the time the Constitution was adopted it was anticipated that future Heads of State would be chosen from among the four Tama-a-Aiga 'royal' paramount chiefs. However, this is not required by the Constitution and for this reason Samoa can be considered a republic rather than a constitutional monarchy like the United Kingdom. Parliament (the Fono) can also amend the constitution through a simple majority of votes in the house. System of government The Samoa system is a very hard model of parliamentary democracy where the executive and the legislative arms of government are fused together. The prime minister is chosen by a majority in the Fono and is appointed by the head of state to form a government. The prime minister's preferred cabinet of 12 is appointed and sworn in by the head of state, subject to the continuing confidence of the Fono, which since the rise of political parties in Samoa in the 1980s, is controlled by the party with the majority of members in the Fono (the government). The unicameral legislature, named the Fono Aoao Faitulafono (National Legislative Assembly) contains 49 members serving five-year terms. Forty-seven are elected from ethnic Samoan territorial constituencies; the other two are chosen by the Samoan citizens of non-Samoan origin on a separate electoral roll. Universal suffrage was extended in 1990, but only chiefs (matai) may stand for election to the Samoan seats. There are more than 25,000 matai in the country, about 5% of whom are women. The third Tamaaiga Tuimalealiifano was the deputy Head of State or a member of the Council of Deputies when Samoa gained its independence in 1962. Judicial system The judicial system is based on English common law and local customs. The Supreme Court of Samoa is the court of highest jurisdiction. The Court of Appeal has limited jurisdiction to hear only those cases referred to it by the Supreme Court. Below the Supreme Court are the district courts. The chief justice of the Supreme Court is appointed by the Head of State on the recommendation of the Prime Minister. Perhaps the most important court in Samoa is the Land and Titles Court of Samoa, consisting of cultural and judicial experts appointed by the supreme court. This court hears village land and title succession disputes. The court derives from the Native Land and Titles Commission put in place under the German colonial administration in
