Federal Appeals Court Rules in Favor of CACI in Abu Ghraib Case

Arlington, VA, September 14, 2009 - CACI International Inc (NYSE:CACI) announced today that it welcomes a ruling handed down by the U.S. Court of Appeals for the D.C. Circuit dismissing the claims in two lawsuits filed in 2004. The Court held that the federal interest in the prosecution of war was sufficiently strong to preempt the Iraqi plaintiffs' state law tort claims against CACI.

"The Court's decision today is an important step toward resolving all legal matters regarding the company's mission and duties in Iraq. None of the Iraqi plaintiffs in these lawsuits even alleged that they had any contact with anyone affiliated with CACI. Indeed, the Court acknowledged that the Army's investigation found that the lead plaintiff was never actually interrogated or abused. No CACI personnel appeared in any of the notorious photographs at Abu Ghraib and no one affiliated with the company has been charged with any wrongdoing. We have said from day one that these lawsuits are completely without merit and today's ruling vindicates that position," said Paul Cofoni, CACI President and Chief Executive Officer.

"CACI did its work at Abu Ghraib prison with professionalism and integrity. We are proud of the work we did in very difficult and dangerous conditions, in a war zone. The Army was in need of help and we provided qualified professionals who made valuable contributions to the war effort in Iraq. We assisted the Army in obtaining useful intelligence information that helped save the lives of American troops on the battlefield," Cofoni added.

In April of 2008 CACI released the book Our Good Name, which is a true and factual accounting of CACI's involvement at Abu Ghraib. The principal author, Dr. J.P. London, CACI Chairman of the Board, was CACI's President and CEO at the time of the Abu Ghraib controversy. London stated, "Our thoroughly researched book is based entirely on public documents and statements, sworn testimony before Congress, official government reports, sworn courts martial testimony, and other highly reputable sources in the public record. Our Good Name is the definitive account of what CACI went through during the Abu Ghraib controversy and media firestorm." The book also tells the American people about the real CACI – a company dedicated to helping our military and our country.
