A two-thirds majority vote is needed to convict on any charge; a three-quarters majority is needed to order a sentence of more than 10 years. All members present must vote to impose the death penalty, and it must be approved by the president. But those enemy combatants and "persons who have engaged in unlawful belligerence" can be detained until "the cessation of hostilities," notwithstanding any jail sentence they receive from the commissions.

Reread that last sentence. It means they can be locked up until hell freezes over because the "War on Terror" will never end.
