The U.S. Supreme Court refused to revive a lawsuit that accused two military contractors of abusing inmates at the Abu Ghraib prison in Iraq, turning away an appeal by 26 onetime prisoners. The inmates sought to sue CACI International..., which helped interrogate prisoners at the facility, and Titan Corp. [now part of L-3 Communications Holdings], which provided translation services...The inmates, who were civilian detainees, said they were subjected to abuses by CACI and Titan employees including beatings, sexual humiliation, exposure to extreme temperatures and rape. In court papers, the inmates said some prisoners were tortured into unconsciousness and several were murdered...A federal appeals court in Washington rejected the suits on a 2-1 vote. The majority said that the Alien Tort Statute generally can’t be invoked against a private party and that contractors are shielded from suits under state law for wartime activities that are closely supervised by the military.
