Tasnim New Agency reports:
Supreme Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei pardoned or commuted prison terms of 102 convicts that had been found guilty by the Iranian Armed Force’s judiciary system.
Article 110 of the Constitution grants the Supreme Leader the right to pardon or reduce the sentences of convicts upon a recommendation from the head of the Judiciary.
The clemency, however, does not apply to all types of convicts[.]
In the U.S., all pardons, including those for military personnel convicted at court-martial, are processed through the U.S. Pardon Attorney. You can find information about specific pardons here. You will see that President Obama has issued a pardon in one general court-martial case so far. President Bush seems to have granted a total of three; if you do not count the several Selective Service cases.
