Members of the Basiji Force are known for attacking reformist politicians and pro-democracy meetings. President Ahmadinejad was a member of the force, but the Supreme Court judges who issued the ruling are not considered to be specifically affiliated with it.

Iran’s Islamic penal code, which is a parallel system to its civic code, says murder charges can be dropped if the accused can prove the killing was carried out because the victim was morally corrupt.

This is true even if the killer identified the victim mistakenly as corrupt. In that case, the law requires “blood money” to be paid to the family. Every year in Iran, a senior cleric determines the amount of blood money required in such cases. This year it is $40,000 if the victim is a Muslim man, and half that for a Muslim woman or a non-Muslim.

In a long interview with the Iranian Student News Agency, a Supreme Court judge, Mohammad Sadegh Al-e-Eshagh, who did not take part in this case, sought Wednesday to discourage vigilante killings, saying those carried out without a court order should be punished.

At the same time, he laid out examples of moral corruption that do permit bloodshed, including armed banditry, adultery by a wife and insults to the Prophet Muhammad.

“The roots of the problems are in our laws,” said Mohammad Seifzadeh, a lawyer and a member of the Association for Defenders of Human Rights in Tehran. “Such cases happen as long as we have laws that allow the killer to decide whether the victim is corrupt or not. Ironically, such laws show that the establishment is not capable of bringing justice, and so it leaves it to ordinary people to do it.”

The ruling stems from a case in 2002 in Kerman that began after the accused watched a tape by a senior cleric who ruled that Muslims could kill a morally corrupt person if the law failed to confront that person.
