The Supreme Court filing follows an April ruling in which a federal appeals court  sided with the Federal Trade Commission’s order to  ProMedica to divest itself of St. Luke’s Hospital in Maumee, Ohio. The judges said the purchase, in reducing competition, would  unfairly raises prices for patients and insurers. Kaiser Health news reported  that  ProMedica  lawyers have argued that the appeals court was flawed in assuming that ”greater market share would lead to price increases. They also have said that selling the community hospital would lead to the hospital’s demise.”

Cambridge Management Group has reported on another important hospital antitrust case, in which a federal appeals court is considering Idaho-based St. Luke’s Health System’s  acquisition of a physician group.
