Certain local zoning laws can’t be used to supersede Ohio’s state-level system for regulating oil and gas drilling, a fiercely divided Ohio Supreme Court ruled, Tuesday, Feb. 17, 2015. In a 4-3 decision with three written dissents, the high court said that the home rule clause of Ohio’s constitution doesn’t allow a municipality to block drilling activities otherwise permitted by the state.
