From 1991, when Kyrgyzstan gained independence from the Soviet Union, until October 2007, when the Constitution was changed in a referendum, the Supreme Council consisted of the Legislative Assembly (Myizam Chygaruu Jyiyny, the upper house) and the Assembly of People's Representatives (El Okuldor Jyiyny, lower house) with 60 and 45 members, respectively. The members of both houses were elected to five-year terms. In the Assembly of People's Representatives all 45 members were elected in single-seat constituencies; in the Legislative Assembly 45 members were elected in single-seat constituencies and 15 were elected through party lists.
Since October 2007, the Supreme Council is a unicameral legislature. Originally it consisted of 90 members, however when in 2010 President Kurmanbek Bakiyev was ousted after riots, a new Constitution was adopted, that increased the number of members to 120. Parties are limited to 65 seats in order to prevent power concentration.
Moldova still considers Transnistria part of its territory, although Transnistria declared independence on 2 September 1990. As Transnistria was not autonomous region before declaration of its independence it had no government bodies of its own in the USSR. It meant that all government authorities had to be formed from scratch.
