Passage: The Dominican Republic is a representative democracy or democratic republic, with three branches of power: executive, legislative, and judicial. The president of the Dominican Republic heads the executive branch and executes laws passed by the congress, appoints the cabinet, and is commander in chief of the armed forces. The president and vice-president run for office on the same ticket and are elected by direct vote for 4-year terms. The national legislature is bicameral, composed of a senate, which has 32 members, and the Chamber of Deputies, with 178 members.Judicial authority rests with the Supreme Court of Justice's 16 members. They are appointed by a council composed of the president, the leaders of both houses of Congress, the President of the Supreme Court, and an opposition or non–governing-party member. The court "alone hears actions against the president, designated members of his Cabinet, and members of Congress when the legislature is in session."The Dominican Republic has a multi-party political system. Elections are held every two years, alternating between the presidential elections, which are held in years evenly divisible by four, and the congressional and municipal elections, which are held in even-numbered years not divisible by four. "International observers have found that presidential and congressional elections since 1996 have been generally free and fair." The Central Elections Board (JCE) of nine members supervises elections, and its decisions are unappealable. Starting from 2016, elections will be held jointly, after a constitutional reform.
