Litigation Status
Oral arguments were heard in federal court in Cheyenne, WY on January 29 to address the state of Wyoming’s request that the USFWS accept the Wyoming Wolf Management Plan. A decision from Judge Allen Johnson is pending.

On February 18, 2009, a hearing was held in federal court in Boise, ID. The Wolf Recovery Foundation, Western Watersheds Project, and 6 other groups requested a temporary restraining order and/or preliminary injunction to prevent IDFG from radio collaring wolves and landing in the Frank Church River-of-No-Return wilderness area.

A hearing on the preliminary injunction request was held in Federal Court in Missoula, MT on August 31. Oral arguments were heard from the plaintiffs, U.S. Department of Interior, Montana, and Idaho. On September 8, the Federal Court denied the preliminary injunction motion filed by Defenders of Wildlife and others to stop the 2009 regulated gray wolf hunts in Idaho and Montana.  However, in issuing his order, the judge indicated that his preliminary review of the overall delisting case raised questions about Service’s approach of conferring ESA protections to a “significant portion of the range” of a species, as opposed to designating the entire species as a threatened or endangered species. A hearing date for oral arguments has not been set, but is expected to be soon after legal briefs are completed in late January 2010.
