Humane Society v. Zinke, No. 15-5041 (D.C. Cir. 2017)Annotate this Case
The Human Society challenged a rule that removes from federal protection a sub-population of gray wolves inhabiting all or portions of nine states in the Western Great Lakes region of the United States. The Human Society alleged that the rule violated the Endangered Species Act (ESA), 16 U.S.C. 1531 et seq., and the Administrative Procedure Act (APA), 5 U.S.C. 551 et seq. The D.C. Circuit affirmed the district court's decision vacating the rule, holding that the government failed to reasonably analyze or consider two significant aspects of the rule: the impacts of partial delisting and of historical range loss on the already listed species.
