The 1979 Constitution of the Islamic Republic calls Iran to have a Head of the Judiciary, also known in English as 'Chief Justice of Iran', who is to be a "just Mujtahid" (high level Islamic cleric) appointed by the Supreme Leader and to serve for "a period of five years." He is responsible for the "establishment of the organizational structure" of the judicial system; "drafting judiciary bills" for Parliament; hiring, firing, promoting and assigning judges. Judges cannot be dismissed without a trial.
