Hamdan v. Rumsfeld

My initial impression on the practical outcome of today's decision is there will not be any trials at all; unlawful combatants held at Gitmo and elsewhere will simply be held for the duration of the war-however long that will be which means they will rot in Cuba until their home country wants to take them.

A completely unrelated observation: the plurailty opinion by Justice Stevens is notable for the contortions it goes through to avoid the plain language of the Detainee Treatment Act which strips the federal courts, including the Supreme Court, of jurisdiction to hear habeas petitions from Gitmo.
