The politics of Serbia function within the framework of a parliamentary democracy. The prime minister is the head of government, while the president is the head of state. Serbia is a parliamentary republic composed of three branches of government: an executive, legislature, and judiciary.
Executive power is exercised by the prime minister, who heads a cabinet. The prime minister is chosen by the National Assembly on the proposal of the president, who names the designate after consultations with all parliamentary leaders. The president is elected based on popular vote, but has little governing power and is primarily a ceremonial position. The president’s term lasts five years and can be elected for at most 2 terms. Cabinet ministers are nominated by the prime minister and confirmed by the National Assembly. Governing power is vested in the prime minister, deputy prime ministers and other ministers. The prime minister is responsible for presenting his agenda to the National Assembly as well as proposing the ministers to fill the cabinet posts in his government. The government is considered elected if it has been elected by a majority vote of all representatives in the National Assembly.
Legislative power is vested in the unicameral parliament known as the National Assembly, which is composed of 250 proportionally elected deputies by secret ballot. The National Assembly also wields constitutional authority in the republic.
The judicial system of Serbia is headed by the Supreme Court of Cassation. The court reviews and possibly rules on past court cases made at the lower court levels. The 2008 Law on Organization of Courts greatly decreased the number of courts in Serbia - from 168 to 64. In addition many different court tiers were established: the Basic, High, and Appellate Courts and as previously mentioned, the Supreme Court of Cassation. There are also special courts of jurisdiction, such the Commercial court, Commercial court of Appeal, Administrative court of Serbia.
