Alaska Wildlife Alliance, Center for Biological Diversity, Defenders of Wildlife, Friends of the Earth, Sierra Club, and others have sued the U.S. Fish & Wildlife Service, alleging that the agency violated the Marine Mammal Protection Act and the Administrative Procedure Act when it granted a 5-year incidental take regulation (ITR) for the Alaska Oil and Gas Association that potentially could kill polar bears and walruses. Plaintiffs are seeking for the court to vacate the ITR and declare that FWS’ issuance of the ITR violated the MMPA and APA.
