Washington (CNN) –- The possible hanging of an Iranian pastor, who may face execution for refusing to recant his Christian beliefs, reached the highest levels of the Iranian government over the weekend with Supreme Leader Ali Khamenei being asked for his opinion on the possible death sentence.

Mohammad Dadkhah, attorney for Pastor Youcef Nadarkhani, told CNN that Nadarkhani was still alive and that the court has asked the highest religious leader in Iran for his input. Though Khamenei has the ultimate authority in Iranian affairs, the move is unusual for a case that was supposed to be decided Monday.

Nadarkhani, the leader of a network of house churches in Iran, was first convicted of apostasy in November 2010, a charge he subsequently appealed all the way to the Iranian Supreme Court. In an appeals trial last month at a lower court in Gilan province, Nadarkhani refused to recant his beliefs.

After the trial, however, reports by the semi-official Fars News Agency on September 30 indicated that the charges against Nadarkhani have since changed and the pastor is now charged with rape and extortion. "This issue has nothing to do with his abandoning his religion," reported Fars.

"He is a Zionist and has committed security-related crimes," Gholomali Rezvanii said in the Fars News report. Renvanii is the deputy governor of Gilan province, where Nadarkhani was tried and convicted.

In a 2010 Iranian Supreme Court brief obtained by CNN, the charge of apostasy is the only charge listed.

"He [Nadarkhani] has stated that he is a Christian and no longer Muslim," states the brief.

"During many sessions in court with the presence of his attorney and a judge, he has been sentenced to execution by hanging according to article 8 of Tahrir – olvasileh."

The case has drawn international attention, with governments from around the world, including the United States, Britain and France, issuing statements on the fate of the pastor.

Nadarkhani "has done nothing more than maintain his devout faith, which is a universal right for people," a White House spokesman said in a statement. "That the Iranian authorities would try to force him to renounce that faith violates the religious values they claim to defend, crosses all bounds of decency and breaches Iran's own international obligations."
