Today, in the long-running litigation over protecting the polar bear under the Endangered Species Act (ESA), the federal district court rejected four lawsuits by sport-hunting groups challenging the Fish and Wildlife Service’s prohibition on importing the body parts of polar bears killed in Canadian “sport hunts.” In these lawsuits the plaintiffs acknowledge that the polar bear requires ESA protection because the species’ sea-ice habitat is being destroyed by global climate change. Nonetheless, the hunters argued that the Marine Mammal Protection Act (MMPA), pursuant to which certain of these imports had been permitted prior to the species’ ESA listing, trumps these threats, and that imports must continue to be allowed.
