HARRISBURG, Pa. -- The state Supreme Court has ordered a halt to a plan by Gov. Tom Corbett's administration to close nearly half of Pennsylvania's 60 community health centers until the justices can hear a lawsuit challenging it. The high court's order, issued Wednesday, reversed a lower court decision on the request for an injunction and asked for a speedy hearing of the case. A state employees' union, Department of Health nurses and several Democratic state lawmakers sued on April 1, saying the plan violates a 1996 law that requires legislative approval before closing any centers.
