After the disputed results of the June 2009 Iranian presidential election were certified by Supreme Leader Ali Khamenei, Chairman Rafsanjani was reported to have called a meeting of the Assembly of Experts, as the Assembly has the constitutional power to hire and fire the Supreme Leader. On 8 March 2011, Ayatollah Mohammad-Reza Mahdavi Kani replaced Ayatollah Rafsanjani as chairman. Mohammad-Reza Mahdavi Kani died in October 2014. On 10 March 2015 the Assembly voted in Ayatollah Mohammad Yazdi to be the next Chairman.
