Center for Biological Diversity v. Haaland

Summary: This case is a challenge to a decision by the U.S. Fish and Wildlife Service ("Service") reversing its previous decision that the Pacific walrus qualified for listing as an endangered or threatened species under the Endangered Species Act of 1973 (“ESA”). In 2008, the Center for Biological Diversity (“Center”) petitioned the Service to list the Pacific walrus as threatened or endangered, citing the claimed effects of climate change on its habitat. In 2011, after completing a species status assessment, the Service issued a 45-page decision ("Decision") that found the listing of the Pacific walrus was warranted, but it declined to list the species because it found the need to prioritize more urgent listings. A settlement between the parties in 2017 required the Service to submit a proposed rule or a non-warranted finding. In May of 2017, the Service completed a final species assessment ("Assessment") that concluded some of the stressors to the species had "declined in magnitude" and the walruses had adjusted, which culminated in "a terse 3-page final decision that the Pacific walrus no longer qualified as a threatened species." As a result, in 2018, the Center filed this action alleging that the 2017 Decision violated the APA and ESA. The District Court granted summary judgement to the Service and this appeal followed. The Ninth Circuit first observed that, while the Assessment contains some new information, it does not explain why this new information resulted in an about-face from the Service's 2011 conclusion that the Pacific walrus met the statutory criteria for listing. The Service contends the appellate inquiry must be limited to the 3-page Decision document from 2017. However, the Court noted that a review of the reasons offered by the Service in its appellate briefing illustrates why the Court cannot conduct the required appellate review without reference to the previous Assessment. The agency's new policy contradicts its prior policy (the Decision document which was 40+ more pages longer than the Assessment and includes citations and other data). The Ninth Circuit now holds that the Service did not sufficiently explain why it changed its prior position. As a result, the Court reversed the district court's grant of summary judgment to the Service and remanded it to the District Court to direct the Service to provide a sufficient explanation of its new position.

Nat. Res. Def. Council, Inc. v. U.S. Dep't of the Interior

Summary: This case centers on the Trump Administration's new interpretation of incidental takings under the Migratory Bird Treaty Act (MBTA). In December 2017, the Principal Deputy Solicitor of the U.S. Department of the Interior (DOI) issued a memorandum that countered almost 50 years of the agency’s interpretation of “takings” and “killings” under the MBTA (the "Jorjani Opinion"). According to the DOI in that opinion, the MBTA does not prohibit incidental takes or kills because the statute applies only to activities specifically aimed at birds. Environmental interest groups and various states brought three now-consolidated actions to vacate the memorandum and subsequent guidance issued in reliance on the memorandum. Both parties moved for summary judgment. In essence, the question before the court is whether DOI’s interpretation of the MBTA must be set aside as contrary to law under the Administrative Procedure Act (APA) or upheld as a valid exercise of agency authority. The court first observed that, from the early 1970s until 2017, the DOI interpreted the MBTA to prohibit incidental takes and kills, imposing liability for activities and hazards that led to the deaths of protected birds, irrespective of whether the activities targeted birds or were intended to take or kill birds. To conserve migratory birds and ensure compliance with the MBTA’s prohibition on “incidental take,” the DOI's Fish & Wildlife Service (FWS) used a range of strategies: sending companies notice of the risks their facilities and equipment posed to migratory birds; issuing industry guidance; informally negotiating remediation efforts; and issuing permits authorizing takes. In fact, the court noted that the agency prioritized a cooperative approach with industry over enforcement actions. In 2015, the DOI formalized this approach by undergoing a rulemaking process regulating incidental take. In early 2017, the DOI's Solicitor then issued a memorandum that reaffirmed the long-standing interpretation that the MBTA prohibited incidental take that became known as the "Tomkins Opinion." Once presidential administrations changed and Tomkins departed, the new Principal Deputy Solicitor issued a new memorandum that stated any agency comments, recommendations, or actions not be based on the principle that the MBTA prohibited incidental take (the Jorjani Opinion). This triggered the instant lawsuits by conservation organizations and several states. On July 31, 2019, the lower court found that the plaintiffs sufficiently demonstrated standing and denied the DOI's motion to dismiss. On appeal here, this court first noted that both parties agree with longstanding precedent that the MBTA's misdemeanor provision creates strict liability. In contrast, the Jorjani Opinion contends that the criminal penalty provisions under the MBTA is limited to only acts directed at birds and those activities whose purpose is to "render an animal subject to human control" like hunting or capturing. In reviewing the Jorjani Opinion under the lessened deference standard afforded by administrative law, this court found the DOI overstated the any conflicts in interpretation of the MBTA among circuit courts (a "dramatized representation"). In addition, the court found the Jorjani Opinion "is a recent and sudden departure from long-held agency positions backed by over forty years of consistent enforcement practices." The court found the Jorjani Opinion was an unpersuasive interpretation of the MBTA's unambiguous prohibition on the killing of birds and is contrary to the plain language of the law itself. Such an interpretation runs contrary to legislative history, decades of enforcement practices by the DOI, and caselaw. Because the agency's action was held unlawful under the APA, the court found the only appropriate remedy was vacatur. Thus, Plaintiffs’ motions for summary judgment were granted, and Interior’s motion was denied.

Am. Anti-Vivisection Soc'y v. United States Dept. of Agric.

Summary: The American Anti-Vivisection Society and the Avian Welfare Coalition sued the Department of Agriculture and its Secretary alleging that the Department's failure to promulgate bird-specific regulations is unreasonable, unlawful, and arbitrary and capricious in violation of the APA. The Plaintiffs sought court-ordered deadlines by which the Department must propose such rules. The Department moved to dismiss the Plaintiff's claims arguing that the Plaintiffs lack standing to sue, that it is not required by law to promulgate regulations for birds, and that it has not taken a final action reviewable by the court. The District Court ultimately held that, although the Plaintiffs have standing to sue, both of their claims fail. The Department is not required by the Animal Welfare Act to issue avian-specific standards; rather, it must to issue welfare standards that are generally applicable to animals. Secondly, although the Department has not taken any action to develop avian-specific standards, that does not mean that will not do so in the future. The District Court granted the department's motion to dismiss.

People for the Ethical Treatment of Animals, Inc. v. United States Department of Agriculture

Summary: In this case, People for the Ethical Treatment of Animals, In.c (PETA) filed a complaint against the United States Department of Agriculture (USDA) for violating the Administrative Procedure Act (APA). PETA argued that the USDA had violated the APA because the USDA has a “policy, pattern, and practice or rubber stamping” exhibitor license renewals to noncompliant animal exhibitors. Under the APA, any agency action that is found to be “arbitrary, capricious, or an abuse of discretion” must be held unlawful by the courts. The court in this case reviewed the facts of the case in accordance with the Chevron decision. According to the court in Chevron, a court must give deference to an agency if: (1) "the statutory language is silent or ambiguous with respect to the question posed," or (2) "the agency’s answer is based on a permissible construction of the statute.” The statutory language that the court considered in this case was the Animal Welfare Act (AWA) that regulate the transportation, handling, and treatment of animals. Ultimately, the court determined that the AWA was silent with regard to exhibitor renewals and therefore moved to the second step of the Chevron decision. The court found that the AWA does not prohibit the USDA’s administrative renewal process for animal exhibitor licenses. The court held that the USDA did not act arbitrarily or abuse its description when it chose to renew certain exhibitor licenses. As a result, the court rejected PETA’s claim against the USDA.

American Wild Horse Preservation Campaign v. Vilsack

Summary: The American Wild Horse Preservation Campaign (Plaintiffs) brought this action against the United States Forest Service (Forest Service) to prevent the implementation of the new Devil’s Garden Wild Horse Territory Plan (WHT) that Modoc County helped develop. Plaintiffs brought six claims against defendants, all under the Administrative Procedures Act. In Counts I, II, and III, plaintiffs alleged that the boundary clarification was arbitrary and capricious because it violated the Wild Horses Act, the National Forest Management Act (NFMA), and National Environmental Policy Act (NEPA), and in Counts IV, V, and VI, they claimed that the adjustment to the "appropriate management level" (AML) range was arbitrary and capricious because it was contrary to the same three statutes. Because the Forest Service reasonably concluded that the disputed territory was never formally incorporated into the Devil's Garden WHT, and that any references to one contiguous territory were the result of administrative error, the Court found that it was not arbitrary and capricious or in violation of the law for the Forest Service to act to correct the boundary in the 2013 Environmental Assessment and the 2013 Management Plan. Thus, defendants were entitled to summary judgment on Counts I, II, and III. And because the Forest Service articulated a rational basis for its decision to adjust the AML range for the Devil's Garden WHT that was not counter to record evidence or otherwise contrary to the law, the Court found that defendants were also entitled to summary judgment on Counts IV, V, and VI. Thus, plaintiffs' motion for summary judgment was denied, defendants' cross-motion for summary judgment was granted, and because they sought the same relief as defendants, the intervenor-defendants' cross-motion for summary judgment was denied as moot.

People for the Ethical Treatment of Animals v. U.S. Dept. of Agriculture

Summary: Ten years after the United States Department of Agriculture (USDA) took steps to apply Animal Welfare Act (AWA) protections to birds, the task remained incomplete. The People for the Ethical Treatment of Animals (PETA) sued the USDA, arguing that its inaction amounted to agency action “unlawfully withheld,” in violation of section 706(1) of the Administrative Procedure Act (APA). The District Court granted the USDA's motion to dismiss, concluding that the USDA's enforcement decisions were committed by law to its discretion. On appeal, the court found PETA had standing, but had failed to plausibly allege that the USDA's decade-long inaction constituted agency action “unlawfully withheld” in violation of the APA. The United States Court of Appeals, District of Columbia Circuit, therefore affirmed the District Court's judgment of dismissal. For the District Court's opinion, see People for the Ethical Treatment of Animals v. U.S. Dept. of Agriculture, 60 F.Supp.3d 14 (D.D.C. 2014).

Center for Biological Diversity, Defenders of Wildlife v. Kelly

Summary: Plaintiffs brought an action against the Defendants, challenging the U.S. Fish and Wildlife Service (“FWS”)'s November 28, 2012 Final Rule designating 30,010 acres in Idaho and Washington as critical habitat for the southern Selkirk Mountains population of woodland caribou under the Endangered Species Act (“ESA”). Specifically, plaintiffs alleged (1) that the Final Rule's critical habitat designation was arbitrary and capricious because the Defendants failed to explain how the limited amount of critical habitat designated was sufficient to recover this population of caribou and (2) that Defendants failed to provide public notice and comment on the substantially revised critical habitat designation before issuing the Final Rule. Defendants and Intervenors argued that the Final Rule satisfied the requirements of the ESA and the Administrative Procedures Act ("APA").While the district court stated that the Final Rule's analysis seemed reasonably based on the best available science, it refused to make a conclusive determination on the arbitrary and capricious issue because procedural requirements necessitated a further public review and comment period. The court therefore found the error in this case was a procedural one resulting from the FWS failing to provide a period of public review and comment on the Final Rule's critical change in reasoning. The Court therefore remanded this matter to the FWS to cure the procedural error by affording the necessary public comment period and to consider anew the critical habitat designation in light of those comments.

Humane Society of the United States v. Jewell

Summary: The Humane Society of the United States sued to overturn the United States Fish and Wildlife Service's 2012 Final Rule to delist the Great Lakes gray wolves from the endangered species list. The US District Court called the 2012 Final Rule "arbitrary and capricious" under the Administrative Procedure Act and in violation of the Endangered Species Act. The District Court thus relisted the wolves and placed them back under the control of the United States Fish and Wildlife Service in Michigan, Wisconsin, and Minnesota.

Alliance for the Wild Rockies v. Austin

Summary: Plaintiff challenged the defendants' approval of the Rennic Stark Project in the Ninemile Ranger District of the Lolo National Forest under the National Environmental Policy Act, the National Forest Management Act, the Endangered Species Act, and the Administrative Procedure Act. The Project proposed a host of forest management measures. Under the National Environmental Protection Act, the defendant published an Environmental Assessment (“EA”) for the project in November 2012. The EA discussed the likely effects of the project on a number of wildlife species, including the ESA-listed threatened Canada lynx, the Forest Service-sensitive fisher, the Forest Service-sensitive North American wolverine, goshawk, and westslope cutthroat trout. The defendant signed and issued a Decision Notice adopting Alternative 2 from the EA, as well as a Finding of No Significant Impact. Plaintiff timely appealed the defendant's decision, but the defendant denied the appeal. Plaintiff then filed its complaint in this court and moved for summary judgment. Defendants filed their cross-motion for summary judgment. Plaintiff's motion for summary judgment was denied on all claims and defendants’ motion for summary judgment was granted on all claims.

Defenders of Wildlife v. Jewell

Summary: In 2012, a rule transferred management of the gray wolf in Wyoming from federal control to state control. In the present case, plaintiffs Center for Biological Diversity, Defenders of Wildlife, Fund for Animals, Humane Society of the United States, Natural Resources Defense Council, and Sierra Club, challenged the United States Fish and Wildlife Service’s decision to remove the gray wolf from the endangered species list in Wyoming. Plaintiffs moved for summary judgment, and maintained that the decision was arbitrary and capricious because Wyoming's regulatory mechanisms were inadequate to protect the species, the level of genetic exchange shown in the record did not warrant delisting, and the gray wolf was endangered within a significant portion of its range. Given the level of genetic exchange reflected in the record, the Court decided not to disturb the finding that the species had recovered, and it would not overturn the agency's determination that the species was not endangered or threatened within a significant portion of its range. However, the Court concluded that it was arbitrary and capricious for the Service to rely on the state's nonbinding promises to maintain a particular number of wolves when the availability of that specific numerical buffer was such a critical aspect of the delisting decision. The Court therefore granted plaintiffs' motion for summary judgment in part, denied it in part, and remanded the matter back to the agency.
