The U.S. Supreme Court is considering whether to hear an appeal filed by Merck, which is attempting to reverse a decision by the U.S. Court of Appeals for the Third Circuit, which reinstated more than 1,000 Fosamax femur fracture lawsuits pending in the federal court system last year. A petition has been filed asking the Supreme Court to overturn a decision that restored the lawsuits after they were originally thrown out by the trial judge.
