HARRISBURG (AP) – The Wolf Administration has ended a lawsuit against IBM after suing the company four years ago and accusing it of failing to deliver on a contract to produce an updated system for processing unemployment compensation claims. The Department of Labor and Industry refused to reveal any terms other than saying that IBM “acknowledged no liability or wrongdoing.” The department only filed a one-sentence discontinuance in court. The lawsuit said the tech giant was paid $170 million on a 2006 contract, but had delivered a failed project by the time the state let the contract expire in 2013. IBM had said the state’s claims had no merit.
