A federal judge on Friday refused to force the Defense Department to provide defense attorneys alternative housing at Guantanamo Bay amid fears their current quarters are unsafe.

The four plaintiffs, U.S. Judge Advocate General’s Corps and civilian lawyers who represent detainees before the military commission at Guantanamo, sued the Department of Defense, the U.S. Navy and the director of the Office of Military Commissions and Convening Authority last year, alleging they failed to properly investigate environmental hazards at Camp Justice.
