I haven't actually looked at the age restrictions, if any, on the Crimes Against Humanity and War Crimes Act, but that act, if it's age appropriate, would give us jurisdiction as well as the Criminal Code, because it's a universal-jurisdiction offence if Mr. Khadr is guilty of war crimes, which is the nature of the allegation.
In terms of abusive treatment, let me read you something from a Human Rights Watch report. It says:
In Guantanamo, Khadr has been held in prolonged detention in solitary confinement. He has told his lawyers that he was also subjected to abusive interrogation. He said his interrogators shackled him in painful positions, threatened him with rape, and used him as a “human mop” after he urinated on the floor during one interrogation session.
So there is some evidence of abusive treatment in his case.
