Estonia. Riigikogu

The Riigikogu (Estonian: [ˈriːɡ̊iˈkoɡ̊u], from Estonian riigi-, "of the state", and kogu, "assembly") 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 (either alone or, if necessary, together with representatives of local government within a broader electoral college) 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.
