The unicameral legislature (Fono) contains 49 members serving 5-year terms. Forty-seven are elected from territorial districts by ethnic Samoans districts; the other two are chosen by non-Samoans on separate electoral rolls. Universal suffrage was extended in 1990, but only chiefs (matai) may stand for election to the Samoan seats. There are more than 25,000 matais in the country, about 5% of whom are women. The prime minister is chosen by a majority in the Fono and is appointed by the chief of state to form a government. The prime minister's choices for the 12 cabinet positions are appointed by the chief of state, subject to the continuing confidence of the Fono.

The judicial system is based on English common law and local customs. The Supreme Court is the court of highest jurisdiction. Its chief justice is appointed by the chief of state upon the recommendation of the prime minister.
