In Humane Society of the United States v. Jewell, a federal district court invalidated the Endangered Species Act (ESA) delisting of wolves in the western Great Lakes (WGL) Distinct Population Segment. This decision culminated a long history of litigation over wolves in the WGL region, and has generated a political backlash, with congressional attempts to delist wolves and to weaken the ESA itself. The author argues that the Jewell court’s analysis is erroneous on several central legal issues. As a policy matter, delisting the WGL wolves and returning them to state control should increase social tolerance of wolves, which is key to the long-term survival of the wolf.
