PA Supreme Court Addresses Agency Deference and the ERA in Ruling on Unconventional Well Drilling Regulations
Earlier this month, the Pennsylvania Supreme Court affirmed in part and reversed in part a preliminary injunction issued by the Pennsylvania Commonwealth Court with respect to newly promulgated regulations regarding unconventional well drilling. Marcellus Shale Coal. v. Dep't of Envtl. Prot. of Commonwealth, 115 MAP 2016, 2018 WL 2452607 (June 1, 2018). In the decision, the Court rejected the argument that courts should defer to a regulatory agency when deciding a preliminary injunction with respect to the agency’s authority to issue regulations, and also shed light on how it interprets allegations of vagueness and conflict in agency regulations. The majority opinion was authored by Chief Justice Saylor and was joined in full by all the associate justices except for Justice Donohue, who authored a concurring and dissenting opinion. Justice Donohue’s opinion, perhaps most notably, voices her disagreement with the Commonwealth Court’s interpretation of Article 1, Section 27 of the Pennsylvania Constitution, known as the Environmental Rights Amendment.
