Part of the Kingdom of the Netherlands, Aruba has full autonomy on all internal affairs with the exception of defense, foreign affairs, and the Supreme Court. The constitution was enacted in January 1986. Executive power rests with a governor while a prime minister heads an eight-member Cabinet. The governor general is appointed for a 6-year term by the monarch, and the prime minister and deputy prime minister are elected by the Staten for 4-year terms. The legislature or Staten is made up of 21 members elected by direct, popular vote to serve 4-year terms. Aruba's judicial system, which has mainly been derived from the Dutch system, operates independently of the legislature and the executive. Jurisdiction, including appeal, lies with the Common Court of Justice of Aruba and the Supreme Court of Justice in the Netherlands.
