The state of Pennsylvania has appealed a court decison on the zoning portion of the state's Act 13 drilling law,
The state late Friday appealed the decision by the state appeals court to the state supreme court.
The decision by the appeals court overturns a key part of the new state law that would have limited local control over where such drilling is allowed.
The law would have stripped municipalities of zoning rights and handed state agencies sole authority to determine where hydraulic fracturing or fracking would be permitted.
