Mohammad Kazem Taghavi considers the right to self-determination to be the source of legitimacy for democratic governments. He argues that this principle is frequently reflected in Imam Khomeini's writings and works. On February 1, 1979 (12 Bahman 1357), at Behesht-e Zahra Cemetery, Imam Khomeini described the monarchy itself as contrary to the law, rational principles, and human rights.
Another piece of evidence is Imam Khomeini's address to the Assembly of Experts for the Constitution. Although the majority of its members were prominent Islamic jurists and scholars, Imam told them that they were representatives (trustees) of the people, not the people's guardians or rulers.
He also cites two other documents: a letter to Ayatollah Meshkini, in which Imam makes the binding authority of the Leader's ruling conditional upon his selection by an Assembly of Experts whose members are themselves elected by the people; and his 1987 (1366 SH) response to an inquiry from the Secretariat of the Friday Prayer Leaders, in which he states that assuming authority over Muslim affairs (tawalli) depends on the vote of the majority of the people.
"You are representatives of the people; you are not the people's guardians."
