The Supreme Court Monday rejected an appeal from former detainees at Abu Ghraib, the Baghdad prison U.S. military forces shared use of with the Iraqi government between 2003 and 2006. The detainees wanted to sue U.S. contractors for abuse in interrogation situations, Politico reported.

The plaintiffs, Iraqis who had been in the prison or had family members in the prison, said that interrogation group CACI International Inc. and translator Titan Corp. had used tactics such as beatings, electrocution, sexual humiliation and rape.

The Supreme Court let a Washington, D.C. federal court's 2-1 decision to throw out the case against the contractors in 2009 stand, without comment.

The Obama administration had urged the Supreme Court to reject the appeal of the lower court's decision, and wait until more lower courts set precedent in similar cases.

Members of the military were court marshaled and tried for misconduct connected to Abu Ghraib, which became a national embarrassment in 2004 when pictures of U.S. troops abusing inmates there surfaced, but no contractors have been punished.
