Assembly of Experts

The Assembly of Experts, also translated as the Assembly of Experts of the Leadership or as the Council of Experts, is the deliberative body empowered to appoint the Supreme Leader of Iran. All directly elected members must first be vetted by the Guardian Council.

All candidates to the Assembly of Experts must be approved by the Guardian Council whose members are, in turn, appointed either directly or indirectly by the Supreme Leader. The Assembly consists of 88 Mujtahids that are elected from lists of thoroughly vetted candidates by direct public vote for eight-year terms. The number of members has ranged from 82 elected in 1982 to 88 elected in 2016. Current laws require the assembly to meet at least twice every six months.
