(Reuters) - The University of Pittsburgh Medical Center, accused by the City of Pittsburgh of not deserving its status as a tax-exempt charitable institution, has fired back with its own suit, alleging that Pittsburgh violated the healthcare center's constitutional rights. In a lawsuit filed on Friday in the U.S. District Court for the Western District of Pennsylvania, the university medical center claimed that Pittsburgh violated its rights to equal protection and due process, and to engage in interstate and international commerce. Friday's suit was responding to a March 20 case filed by the city and its mayor, Luke Ravenstahl, in a Pennsylvania Court of Common Pleas.
