It certainly is, and the "court" in Gitmo failed to declare him an illegal combatant. But that's only one of the many legal frailties that surround his case and convictions, so there are strong arguments to support them being overturned. As a side note though, I'll bet his lawyer/guardian Dennis Edney has had a frank discussion or two with Khadr telling him don't even get a bloody speeding ticket for the time being at least.
