Iran’s Supreme court sent back the case of a Christian pastor sentenced to death for apostasy to the lower court that tried him, saying there had been insufficient investigation before the original trial, students news agency ISNA said on Tuesday.

Yousof Nadarkhani, 33, was arrested and sentenced to death in the northern city of Rasht in 2009. An appeals court upheld his sentence last year after he refused to reconvert to Islam, his lawyer Mohammad Ali Dadkhah told Reuters last week.

“The Supreme Court has returned the case of Nadarkhani to the lower court that originally issued the death sentence … The decision was made due to insufficient investigations,” ISNA quoted a statement issued by the judiciary.

“The court will issue a new verdict … if Nadarkhani appeals the verdict then the case will be sent again to the Supreme Court,” the statement said.
