On 2–3 December 1979, the Constitution of the Islamic Republic of Iran was ratified by popular referendum. In this referendum, 99.5 present of Iranian voters approved the constitution. Ten years later, in the summer of 1989, Iranian voters would approve a set of amendments to the Constitution of 1979 in another referendum. The constitution has been called a "hybrid" of "theocratic and democratic elements". While Articles 1 and 2 vest sovereignty in God, Article 6 "mandates popular elections for the presidency and the Majlis, or parliament." However all democratic procedures and rights are subordinate to the Guardian Council and the Supreme Leader, whose powers are spelled out in Chapter Eight (Articles 107-112).
