The Center for Biological Diversity and eighteen other nonprofit organizations appealed the district court's summary judgment in favor of the United States Fish and Wildlife Service.  The Center claimed the Secretary of the Interior violated the Endangered Species Act by making an erroneous, arbitrary, and capricious determination that listing the Northern Goshawk (a short-winged, long-tailed hawk that lives in forested regions of higher latitude in the northern hemisphere and is often considered an indicator species) in the contiguous United States west of the 100th meridian as a threatened or endangered species was not warranted.  In the absence of evidence that the goshawk is endangered or likely to become endangered in the foreseeable future, the court found the FWS's decision was not arbitrary or capricious and affirmed the summary disposition.

Plaintiff Center for Biological Diversity (CBD) seeks to compel Defendants to perform their mandatory duty under the Endangered Species Act (ESA) to publish a final listing determination for the polar bear. Plaintiffs have filed a summary judgment motion seeking an injunction and declaratory judgment to this effect. The action began back in 2005 when CBD petitioned to list the polar bear as endangered under the ESA.  Plaintiffs' action arises from Defendants' failure to issue a final listing determination and critical habitat designation by January 9, 2008-within one year of publication of the proposed rule-as required by the ESA (16 U.S.C. § 1533(b)(6)). Since Defendants missed this non-discretionary deadline, and there was no dispute of material fact, summary judgment was granted by the court.

This case questions whether the federal government's policy for listing killer whales under the Endangered Species Act is invalid. The Fish and Wildlife Service initially issued a proposed ruling that listing the Southern Resident was “not warranted” because the Southern Resident was not “significant” to its taxon. The district court set aside the Service's “not warranted” finding, and ordered the Service to reexamine whether the Southern Resident should be listed as an endangered species and to issue a new finding within twelve months. After again being challenged by plaintiff, the Service issued a final rule listing the Southern Resident as an endangered (as opposed to threatened) species. The Service contends that this case is now moot because it has, since the district court's decision, issued a proposed rule that recommended listing the Southern Resident as a threatened species and ultimately has issued a final rule listing the Southern Resident as an endangered species. This court agreed, and thus vacated the district court's order and remanded the case with instructions to dismiss the case as moot.

Several public interest groups brought actions challenging Environmental Protection Agency's (EPA) decision to transfer Clean Water Act (CWA) pollution permitting program for Arizona to that State.  Under federal law, a state may take over the Clean Water Act pollution permitting program in its state from the federal Environmental Protection Agency (EPA) if it applies to do so and meets the applicable standards.  When deciding whether to transfer permitting authority, the Fish and Wildlife Service issued, and the EPA relied on, a Biological Opinion premised on the proposition that the EPA lacked the authority to take into account the impact of that decision on endangered species and their habitat.  The plaintiffs in this case challenge the EPA's transfer decision, particularly its reliance on the Biological Opinion's proposition regarding the EPA's limited authority.  The court held that the EPA did have the authority to consider jeopardy to listed species in making the transfer decision, and erred in determining otherwise. For that reason among others, the EPA's decision was arbitrary and capricious. Accordingly, the court granted the petition and remanded to the EPA.

The Humane Society of the United States sought an injunction to prevent the lethal depredation of gray wolves. The district court granted the injunction but, while the case was on appeal, the United States Department of the Interior removed the gray wolf from the Endangered Species List.  After the gray wolf was removed from the Endangered Species List, all parties agreed that the delisting of the gray wolf rendered the appeal moot.  The Court of Appeals vacated the district court's ruling.

This order accompanies the Ninth Circuit's decision in National Audubon v. Davis, 307 F.3d 835 (9th Cir. 2002).

Owners of commercial timberland designated as northern spotted owl nesting habitat brought suit against the United States, alleging that the land was temporarily taken when the Fish and Wildlife Service (FWS) denied their application to cut timber on the property which had been considered critical habitat for the endangered species. The appeals court upheld the lower court and held that no adquate claim for a "takings" was made.

The Government issued regulations which allowed for the sport hunting of the Eastern Timber Wolf  (otherwise known as the gray wolf) in Minnesota, where the wolf was listed as threatened.  The court held that such regulations were invalid because the Endangered Species Act, Section 4(d) required that such regulations must be "for the conservation" of the wolf, which means for the best interest of the wolf.  The court found that the hunting of the wolf in this manner did not have the motive of the best interest of the wolf in mind.

Environmental Groups sued the National Fisheries Service (NMFS) and the United States Department of Commerce for making regulations which allowed swordfish longline fishing along the Hawaii coast, alleging violations of the National Environmental Policy Act (NEPA), the Migratory Bird Treaty Act (MBTA), and the Endangered Species Act (ESA). The Court found that because the regulations were made under the Magnuson-Stevens Fishery Conservation and Management Act of 1976 (Magnuson Act), and because that Act had a 30-day time limit for when challenges to regulations could be made, the environmental groups has not brought their challenge to the regulations in time.

Plaintiff Western Watersheds Project filed the instant action challenging the “90-Day Finding” issued by the Defendants United States Fish and Wildlife Service that denied protection of the Interior Mountain Quail as endangered or threatened under the Endangered Species Act. The Service determined that the Petition had failed to provide information demonstrating that the Interior Mountain Quail population is discrete under the ESA. The District Court stated that, in order to qualify as a DPS, a population must “be both discrete and significant.” The court found that the Service's conclusion appropriately determined that this discreteness standard was not met and it provided a rational basis for concluding the Petition had failed to provide evidence of a marked separation between the populations of the same taxon.

The State Farm Bureaus (a national farm organization)), researchers, and environmental groups appealed from decision of United States and federal agencies to introduce experimental population of gray wolves in a national park and central Idaho. The United States District Court for the District of Wyoming struck down the Department of Interior's final wolf introduction rules and ordered reintroduced wolves removed. In reversing the lower court's decision, the Court of Appeals for the 10th Circuit held that the possibility that individual wolves from existing wolf populations could enter experimental population areas did not violate provision of Endangered Species Act requiring that such populations remain "geographically separate."  Further, the fact that the promulgated rules treated all wolves, including naturally occurring wolves, found within designated experimental population areas as nonessential experimental animals did not violate ESA.

The Wyoming Farm Bureau, amateur researchers, and environmental groups appealed an agency to introduce experimental population of gray wolves in a national park and central Idaho. After ruling on the various standing issues, the court held that the ESA section allowing experimental population to be maintained only when it is "wholly separate geographically" from nonexperimental populations includes overlap even with individual members of nonexperimental species.  However, the defendants' treatment of all wolves found within boundaries of designated experimental population areas as nonessential experimental animals was contrary to law as provided in their own regulations.  Therefore, the court ordered that Defendants' Final Rules establishing a nonessential experimental population of gray wolves in Yellowstone National Park in Wyoming, Idaho, Montana, central Idaho and southwestern Montana was unlawful.  Further, that by virtue of the plan being set aside, defendants must remove reintroduced non-native wolves and their offspring from the Yellowstone and central Idaho experimental population areas. This decision was reversed in 199 F.3d 1224.
