Under Article 62, the Islamaic Consultative Assembly is elected directly by the people through a secret ballot. Eligible voters must either be birthright citizens of the Islamic Republic of Iran or naturalized citizens and of an age dictated by referendums and law. Under Article 6, the President and referendums must also be voted on by the public. (Constitute Project, “Iran’s (Islamic Republic of) Constitution of 1979 with Amendments through 1989”).
