A U.S. district judge has ruled Iraqi torture victims and their relatives can proceed with a lawsuit against a defense contractor involved in abuse scandals at Abu Ghraib and other U.S. prisons in Iraq. The lawsuit says interrogators with CACI International practiced torture or mistreatment of Iraqi prisoners. In the same ruling, Judge James Robertson dismissed claims against co-defendant Titan on the grounds the company’s guards were under the military’s exclusive control. But he said the case against CACI can go forward because company officials were also involved in the chain of command.
