In an important victory for the state’s vulnerable wildlife species, the Massachusetts Supreme Judicial Court (“SJC”) recently upheld the Massachusetts Endangered Species Act (“MESA”) regulations in all respects. The case, known as Pepin v. Division of Fisheries and Wildlife, 467 Mass. 210 (2014), challenged the procedural and substantive jurisdiction implemented by the state Division of Fisheries and Wildlife (“DFW”) under MESA.
