The National Assembly (; “Country Assembly”) is the parliament of Hungary. The unicameral body consists of 199 (was 386 between 1990 and 2014) members elected to 4-year terms. Election of members is based on a complex system involving both area and list election; parties must win at least 5% of the popular vote in order to enter list members the assembly (but area winners enter regardless). The Assembly includes 25 standing committees to debate and report on introduced bills and to supervise the activities of the ministers. The Constitutional Court of Hungary has the right to challenge legislation on the grounds of constitutionality. The assembly has met in the Hungarian Parliament Building in Budapest since 1902.
