Head of Iran's Electoral Office Kamran Daneshjou objects to the Reformist camp's proposal of putting the legitimacy of the Ahmadinejad government to referendum, Press TV reported.
"By participating in the election, the people chose for themselves and determined their path. We must respect the people's choice," Daneshjou told IRNA on Sunday.
Daneshjou was referring to a proposal put forth by Iran's former Reformist president Mohammad Khatami and one of the camp's leading parties, the Association of Combatant Clerics.
"There is no logic in these comments... holding a referendum for every election would create an endless cycle. They know fully well that it is impossible," he said.
Last week, Khatami proposed a "referendum" on the legitimacy of the government to end the political tensions, which followed the June 12 presidential election.
In a meeting with family members of the detainees who were arrested during protests against the result of the presidential vote, Khatami said what happened after the poll had blemished the "Republican and Islamic nature of the establishment".
"The only way out of the current situation is to hold a referendum... If the majority of people accept the situation, we will accept it as well," he said.
"Public trust should be returned to the society ... We announced from the start that there are legal ways to restore this trust, but our calls were ignored," the former Iranian president added.
Hours later the Association of Combatant Clerics endorsed Khatami's call in an official statement posted on its website.
"As millions of Iranians have lost confidence in the electoral process, the Association of Combatant Clerics insists on the organization of a referendum... by independent bodies."
