CINCINNATI - A federal judge in Tennessee did not err in vacating an order imposing sanctions against the state's Medicaid program after he was assigned to the case, a Sixth Circuit U.S. Court of Appeals panel ruled March 13, finding that he applied the proper legal standard and fully explained his decision to reverse the ruling (John B., et al. v. Mark Emkes, Commissioner, Tennessee Department of Finance and Administration, et al., No. 12-5414, 6th Cir.; 2013 U.S. App. LEXIS 5258).
