The Riigikogu is the unicameral parliament of Estonia. In addition to approving legislation, the Parliament appoints high officials, including the prime minister and chief justice of the Supreme Court, and elects the president. Among its other tasks, the Riigikogu also ratifies significant foreign treaties that impose military and proprietary obligations and bring about changes in law, as well as approves the budget presented by the government as law, and monitors the executive power.
Estonia elects a legislature on the national level. The Riigikogu has 101 members, elected for a four-year term by proportional representation. A head of state – the president – is elected for a five-year term by parliament or an electoral college. Locally, Estonia elects local government councils, which vary in size. Election law states the minimum size of a council depending on the size of municipality. Local government councils are elected by proportional representation too.
