The National Assembly is a unicameral legislature. It has 33 members who are elected for 5-year terms. Elections take place within a multi-party system; in 2009, the American NGO Freedom House ranked the Republic of Artsakh above the republics of Armenia and Azerbaijan with respect to civil and political rights. Five parties have members in the parliament: the Free Motherland party has 15 members, ARF has 8 members, Democratic Party of Artsakh has 7 members, Movement 88 has 2 members and the National Revival party has one member. A number of non-partisan candidates have also taken part in the elections, with some success; in 2015, two of the 33 members to the National Assembly took their seats without running under the banner of any of the established political parties in the republic. Elections in Artsakh are not recognised by international bodies such as the European Union and the Organisation of Islamic Cooperation, as well as numerous individual countries, who called them a source of increased tensions.
