The National Assembly of Vietnam is the unicameral state legislature composed of 500 members. Headed by a chairman, it is superior to both the executive and judicial branches, with all government ministers being appointed from members of the National Assembly. The Supreme People's Court of Vietnam, headed by a chief justice, is the country's highest court of appeal, though it is also answerable to the National Assembly. Beneath the Supreme People's Court stand the provincial municipal courts and many local courts. Military courts possess special jurisdiction in matters of state security. Vietnam maintains the death penalty for numerous offences.
