[JURIST] Lawyers for Omar Khadr [JURIST news archive], the Canadian citizen who is detained at Guantanamo Bay [JURIST news archive] and charged with killing a US Special Forces soldier in Afghanistan, said Thursday they will seek his extradition to Canada. The request follows Thursday's US Supreme Court [official website] ruling in Hamdan v. Rumsfeld [opinion text; JURIST report], which held that Guantanamo military commissions [DOD materials] are illegal under military law and the Geneva Conventions [ICRC materials] and that President Bush did not have authority to establish the commissions as constituted.

Of the approximately 450 men still detained [DOD press release] at Guantanamo, Khadr is one of 10 prisoners who have been charged. He is accused [charge sheet, PDF; JURIST report] of throwing a grenade that killed a US Green Beret and of planting mines to blow up US convoys. Canadian Press has more.
