Iranian Justice Minister has said there is 'no need' for a man who survived a hanging to be hanged a second time.
Lawyers want the head of the judiciary to stop a repeat hanging after a man was found alive in a morgue.
Mostafa Pourmohammadi said executing the man would have repercussions against Iran's image.
According to the BBC, the government has no direct control over the judiciary which has to decide whether a second execution takes place.
The 37-year-old convicted drug smuggler, Alireza M, was found alive in a morgue after being hanged at a jail in the north-eastern city of Bojnord last week.
He had been left to hang for 12 minutes after which a doctor declared him dead.
