Iran may soon enough reach the point where the “constitution of the islamic republic” won’t matter anymore.
But for the time being, we have to understand the constraints for the present regime. Here is another clause:
Article 131 [Interim President]
In case of death, dismissal, resignation, absence, or illness lasting longer than two months of the President or when his term in office has ended and a new president has not been elected due to some impediments, or similar other circumstances, his first deputy shall assume, with the approval of the Leader, the powers and functions of the President. The Council, consisting of the Speaker of the Islamic Consultative Assembly, head of the judicial power, and the first deputy of the President, is obliged to arrange for a new President to be elected within a maximum period of fifty days. In case of death of the first deputy to the President, or other matters which prevent him to perform his duties or when the President does not have a first deputy, the Leader shall appoint another person in his place.
Article 132 [Restricted Interim Period]
During the period when the powers and responsibilities of the President are assigned to his first deputy or the other person in accordance with Article 131, neither can the Ministers be interpellated nor can a vote of no confidence be passed against them. Also, neither can any step be undertaken for a review of the Constitution, nor a national referendum be held.
