Judges had found the verdict against Amir Mirzai Hekmati was "not complete" and referred his case to an affiliate court, a judiciary spokesman said.
In January, Mr Hekmati was convicted of "co-operating with a hostile nation, membership of the CIA and trying to implicate Iran in terrorism".
The US has urged Iran to release him.
It has repeatedly insisted the allegations that Mr Hekmati either worked for, or was sent to Iran by the CIA, are "simply untrue".
Mr Hekmati's family, who live in Arizona, have also said the charges are fabricated and that he was in Iran last year to visit his grandmothers. » | Monday, March 05, 2012
