The Hamdi decision may also explain the much-discussed section 948d of the Military Commissions Act.
In 03-6696 (6-28-2004), the Supreme Court held:
The United States Court of Appeals for the Fourth Circuit held that petitioner's detention was legally authorized and that he was entitled to no further opportunity to challenge his enemy-combatant label. We now vacate and remand. We hold that although Congress authorized the detention of combatants in the narrow circumstances alleged here, due process demands that a citizen held in the United States as an enemy combatant be given a meaningful opportunity to contest the factual basis for that detention before a neutral decisionmaker. (p1)
Even in cases in which the detention of enemy combatants is legally authorized, there remains the question of what process is constitutionally due to a citizen who disputes his enemy-combatant status. (p17)
We therefore hold that a citizen-detainee seeking to challenge his classification as an enemy combatant must receive notice of the factual basis for his classification, and a fair opportunity to rebut the Government's factual assertions before a neutral decisionmaker. (p26)

A finding, whether before, on, or after the date of the enactment of the Military Commissions Act of 2006, by a Combatant Status Review Tribunal or another competent tribunal established under the authority of the President or the Secretary of Defense that a person is an unlawful enemy combatant is dispositive for purposes of jurisdiction for trial by military commission under this chapter.
