Assistance to Guantanamo prisonersEdit

Attorneys from Debevoise & Plimpton worked on behalf of prisoners held in extrajudicial detention in the United States Guantanamo Bay detention camps, in Cuba.[14][15][16] Jeff Lang, of Debevoise & Plimpton, was one of the first Guantanamo Bay attorneys to file an appeal in the Federal appeal court in Washington DC of prisoners' Combatant Status Review Tribunal proceedings. The Detainee Treatment Act of 2005 included provision for prisoners to challenge whether the Tribunals' decisions complied with the Tribunal's mandate. Charles "Cully" Stimson, then Deputy Assistant Secretary of Defense for Detainee Affairs, stirred controversy when he went on record criticizing the patriotism of law firms that allowed employees to assist Guantanamo prisoners: "corporate CEOs seeing this should ask firms to choose between lucrative retainers and representing terrorists."[17] Stimson's views were widely criticized. The Pentagon disavowed them, and Stimson resigned shortly thereafter.
