A federal appeals court on Friday dismissed a lawsuit against two U.S. defense contractors by Iraqi torture victims, saying the companies had immunity as government contractors... The plaintiffs sued CACI International Inc, which provided interrogators at Abu Ghraib, and L-3 Communications Holdings Inc's Titan unit, which provided interpreters to the U.S. military... Judge Merrick Garland dissented. "No act of Congress and no judicial precedent bars the plaintiffs from suing the private contractors..." he said.
