In plain English...

LT. CMDR. CHARLES SWIFT, SALIM AHMED HAMDAN‘S LAWYER: At stake was the rule of law. The president had staked out a position that was contrary both to international law and to our domestic statutes in the Uniform Code of Military Justice. What the court did was say that even the president has to follow the law. And that if we‘re going to try people, we‘re going to do it under the law, not under an ad hoc system.

Exactly.

No wonder this guy won.
