According to the Canadian courts, what happens in Pakistan does not stay in Pakistan. The Supreme Court of Canada recently refused to review a permanent stay of extradition proceedings against Abdullah Khadr. Lower courts had previously ruled that "gross misconduct" by the US in arranging and prolonging Khadr's detention in Pakistan justified the extraordinary remedy of a stay of proceedings. The Supreme Court's refusal to consider this case means that Khadr will not be extradited to the US, where he has been indicted on charges of material support of terrorism for allegedly supplying arms and explosives to be used against US forces in Afghanistan. It is possible, but not probable, that Canadian authorities will prosecute Khadr, who was released in August 2010 after four-and-a-half years of pre-extradition custody and has still not been charged in Canada.
