Iran’s political system places enormous power in the office of the Supreme Leader, who serves as the country’s highest religious and political authority. The process for appointing and, if necessary, replacing this leader is clearly defined in the Iranian Constitution and is designed to be carried out by specific clerical institutions rather than by direct public vote.
The Role of the Assembly of Experts
Under Iran’s Constitution, the Supreme Leader is appointed by the Assembly of Experts an 88-member clerical body made up of Islamic jurists elected to eight-year terms. These clerics are elected by the public, but their candidacy must first be vetted and approved by the Guardian Council before they can run for a seat.
When the office of the Supreme Leader becomes vacant due to death, resignation, or disqualification the Assembly of Experts convenes to deliberate and choose a successor. Members of the Assembly assess eligible candidates based on constitutional criteria, which include deep knowledge of Islamic law, political and administrative capability, and leadership qualities. A candidate who receives a majority of votes from the Assembly is appointed as the new Supreme Leader.
The Assembly’s authority is grounded in Article 107 and Article 111 of Iran’s Constitution, which place the responsibility for both selecting and supervising the Supreme Leader with this body. The Iran Primer
The Guardian Council’s Screening Role
Before members can serve in the Assembly of Experts, they must be vetted by the Guardian Council, a powerful institution that oversees the eligibility of candidates for key political bodies. The Guardian Council consists of senior jurists and legal scholars, and its oversight ensures that the clerical majority in Iran’s leadership structures aligns with the constitutional framework.
This screening process effectively ensures that those who will have a say in selecting the Supreme Leader meet strict religious and ideological qualifications. While members of the Assembly are elected, this vetting mechanism means the field of eligible clerics is tightly controlled.
What Happens When the Leadership Becomes Vacant
In the event that the Supreme Leader’s position becomes vacant, Article 111 of the Constitution requires the Assembly of Experts to act quickly to appoint and introduce a new leader. Until a permanent successor is chosen, a temporary leadership council may assume responsibilities. This interim body typically includes the President, the Head of the Judiciary, and a senior cleric from the Guardian Council chosen by the Assembly.
This framework is designed to maintain continuity in governance while preserving the constitutional role of Iran’s senior clerical institutions.
A Unique System of Leadership
Unlike systems where heads of state are directly elected by the public, Iran’s process for appointing its Supreme Leader centers on clerical deliberation and internal decision-making. This underscores the constitutional emphasis on religious authority and institutional oversight in the country’s governance. The Iran Primer
In summary, under Iran’s constitution:
- The Supreme Leader is appointed by the Assembly of Experts an 88-member body of clerics elected by the people.
- Candidates for the Assembly must be vetted by the Guardian Council before being eligible to run.
- When the leadership post becomes vacant, the Assembly convenes to select a successor through internal consultations and a majority vote.
This process ensures that leadership transitions remain rooted in Iran’s constitutional and religious framework, even during periods of political uncertainty.
