Guatemala has a constitutional democratic republic. The county's governing structure includes legislative, judicial and executive branches. The unicameral Congress makes law, and the president, who is the head of government and head of state, holds executive power.
The people of Guatemala vote in direct presidential and congressional elections every four years. The president appoints governors of Guatemala's 22 departments, and mayors of cities are elected through a direct popular vote. The nation's Constitutional Court has five justices, one appointed by the president, one chosen by the University of San Carlos, one selected by the Supreme Court president, one elected by Congress and one chosen by the bar association. Congress elects the 13 justices of the Supreme Court to five-year terms.
