HC Reform Update from Mark Sanna: A federal judge indicated on Tuesday that he would give a green light to a lawsuit filed by elected officials from 20 states who are challenging the constitutionality of the new health care law and its requirement that most individuals obtain medical insurance. Experts on both sides expect the challenges to eventually present the Supreme Court with a landmark opportunity. “Our whole system of federalism rests on the decisions of this case,” said Florida’s attorney general, Bill McCollum, a Republican who is the lead plaintiff in the lawsuit.
