US Supreme Court Rejects Appeal by Canadian-born Detainee

The U.S. Supreme Court on Monday rejected an appeal by Omar Khadr, a Canadian-born former Guantanamo detainee who was seeking to wipe away his war crimes convictions, including killing a U.S. soldier in Afghanistan.
Khadr had waived his right to appeal when he pleaded guilty in 2010 to charges that included murder, but his lawyers argued that a subsequent ruling by the Federal Appeal Court in Washington called into question whether Khadr could have been charged with the crimes in the first place.
Recall that, Khadr had been sentenced to eight years in prison plus the time he already had spent in custody, including several years at the U.S. Naval Base at Guantanamo Bay, Cuba, but was released in May 2015 pending his appeal of the guilty plea.
