HARRISBURG, Pa. - A divided Pennsylvania Supreme Court ruled Dec. 19 that local governments have standing to seek redress for violations of their constitutional mandate to preserve the environment included in the Pennsylvania Constitution declaration of rights and that the amendments to the state gas and oil regulations, known as Act 13 of 2012, violate Pennsylvanians' constitutional right to a clean environment (Robinson Township, et al. v. Pennsylvania, et al., No. 63 MAP 2012 [consolidated], Pa. Sup.).
