 Nevertheless, the Constitutional Court ruled on 4 March 2016, that this constitutional change adopted in 2000 regarding the presidential election was unconstitutional, thus reverting the election method of the President to a two-round system direct election.The president appoints a prime minister who functions as the head of government, and who in turn assembles a cabinet, both subject to parliamentary approval.The 1994 constitution also establishes an independent Constitutional Court, composed of six judges (two appointed by the President, two by Parliament, and two by the Supreme Council of Magistrature), serving six-year terms, during which they are irremovable and not subordinate to any power.
