Justia U.S. 9th Circuit Court of Appeals Opinion Summaries

A group of eighteen minors residing in California filed a lawsuit against the U.S. Environmental Protection Agency (EPA) and other federal officials, claiming that the government’s policy of discounting future costs and benefits in cost-benefit analyses for greenhouse gas (GHG) regulations discriminates against children. The plaintiffs alleged this practice favors present-day consumption, benefiting adults over minors, and leads to under-regulation of GHG emissions. They argued this under-regulation contributes to climate change, which, in turn, causes them various harms including property damage, health issues, and psychological distress.The case was first heard in the United States District Court for the Central District of California. That court dismissed the action, ruling that the plaintiffs lacked Article III standing. The court found that the plaintiffs’ claims did not establish a cognizable injury-in-fact, that the alleged environmental harms were not fairly traceable to the government’s discounting policies, and that the requested declaratory relief would not redress their injuries. The district court allowed the plaintiffs one opportunity to amend their complaint, but after the plaintiffs did so, the court again dismissed the case and denied further leave to amend, finding further amendment would be futile.On appeal, the United States Court of Appeals for the Ninth Circuit affirmed the district court’s dismissal. The Ninth Circuit held that the plaintiffs failed to allege a viable injury to their equal protection rights, as the government’s discounting policies were not shown to be motivated by discriminatory intent toward children. The court also found the alleged environmental harms too attenuated and speculative to be fairly traceable to the challenged policies. Additionally, circuit precedent foreclosed the requested declaratory relief, as it would not redress the plaintiffs’ injuries. The Ninth Circuit concluded that denying further leave to amend was not an abuse of discretion. View "G.B. V. ENVIRONMENTAL PROTECTION AGENCY" on Justia Law

A group of environmental organizations, Native tribes, and individual plaintiffs sought to prevent a land exchange in Southeast Arizona’s Tonto National Forest, mandated by the Southeast Arizona Land Exchange and Conservation Act. This exchange would transfer nearly 2,500 acres of federal land, including Oak Flat—a site of religious significance to the Apache—and a large copper deposit to Resolution Copper Mining LLC. In return, the company would provide over 5,000 acres of equally appraised land to the federal government. Plaintiffs raised concerns under several statutes, including the Land Exchange Act, the National Environmental Policy Act (NEPA), the National Historic Preservation Act (NHPA), the Religious Freedom Restoration Act (RFRA), and the Free Exercise Clause, alleging procedural and substantive flaws in the exchange.The United States District Court for the District of Arizona denied motions for preliminary injunctions, finding that plaintiffs failed to show likely success or serious questions on the merits of their claims relating to appraisal, NEPA compliance, tribal consultation, and religious liberty. In a related case, Apache Stronghold v. United States, the district court’s denial of an injunction on religious liberty grounds was affirmed by the Ninth Circuit and not disturbed by the Supreme Court.On appeal, the United States Court of Appeals for the Ninth Circuit affirmed the district court’s denial of a preliminary injunction. The court held that plaintiffs had Article III standing and that their NEPA claims were justiciable as “final agency action.” However, it concluded that plaintiffs were not likely to succeed on the merits of their appraisal, NEPA, consultation, or religious liberty claims. The court further determined that existing precedent foreclosed the RFRA and Free Exercise arguments. The court did not address other injunction factors and dissolved the administrative stay.

A resident living near a Los Angeles refinery operated by Ultramar Inc., a subsidiary of Valero Energy Corp., challenged the renewal of the refinery’s operating permit. The facility, located in Wilmington, is subject to Title V of the Clean Air Act, which requires certain air polluters to obtain operating permits. The resident argued that the permit should include additional conditions to address the potential for a catastrophic release of hydrogen fluoride or modified hydrofluoric acid. He pointed to alleged deficiencies in the refinery’s Risk Management Plan (RMP), Emergency Response Plan, Emergency Response Manual, and other documents, claiming these left the refinery unprepared for such an event.The South Coast Air Quality Management District (SCAQMD), acting as the Title V permitting authority, solicited public comments before issuing the permit. The petitioner submitted objections during this process, but SCAQMD rejected them and issued the permit. The petitioner then filed an administrative petition with the Administrator of the United States Environmental Protection Agency (EPA), asking the EPA to object to the permit. The EPA Administrator denied the petition, concluding that issues related to risk management plans and accidental release prevention fall under a separate regulatory program, not the Title V permitting process. The Administrator also found that the requirements referenced by the petitioner were not “applicable requirements” of the Clean Air Act for Title V purposes.The United States Court of Appeals for the Ninth Circuit reviewed the EPA’s decision. The court held that the Administrator’s denial was not arbitrary, capricious, or contrary to law. It concluded that the petitioner failed to show that additional permit conditions were required to ensure compliance with the Clean Air Act’s risk management requirements. The court also found that the petitioner’s arguments based on state law did not qualify as applicable federal requirements. Accordingly, the Ninth Circuit denied the petition for review. View "ENG V.

The case concerns the National Marine Fisheries Service’s (NMFS) designation of critical habitat in 2022 for two species of Arctic seals, following their listing as threatened under the Endangered Species Act (ESA) in 2012. The designated areas covered waters off Alaska’s north coast and were based on findings that those areas contained physical and biological features essential to the conservation of the seal species. Alaska opposed these designations, contending that they were too broad and provided minimal benefit, and requested that certain coastal areas be excluded due to economic impacts. NMFS excluded an area used by the Navy for training but declined to exclude others requested by Alaska and the North Slope Borough, finding no significant economic impact.The United States District Court for the District of Alaska largely agreed with Alaska, holding that the critical habitat designations were unlawful. The court vacated the rules and remanded the matter to NMFS, concluding that NMFS had not adequately explained why the entire designated area was necessary for the seals’ conservation, had failed to consider foreign conservation efforts and foreign habitat, and had abused its discretion by not considering certain exclusions. The Center for Biological Diversity intervened as a defendant and appealed the district court’s decision. The district court did, however, reject Alaska’s argument that NMFS had failed to comply with the ESA’s “prudency” requirement.On appeal, the United States Court of Appeals for the Ninth Circuit found that it had jurisdiction, reversed the district court’s rulings that the designations were unlawful, and affirmed the court’s ruling on the ESA’s prudency requirement. The Ninth Circuit held that NMFS’s designations complied with the ESA, that the agency was not required to consider foreign conservation efforts or habitat, and that the decision not to exclude certain coastal areas was within its discretion. The critical habitat designations were reinstated, and the case was remanded with instructions to enter judgment for the Center and NMFS. View "STATE OF ALASKA V.

A federal land exchange was mandated by the Southeast Arizona Land Exchange and Conservation Act, requiring the United States Forest Service to transfer approximately 2,500 acres of National Forest land, including Oak Flat—a site of religious significance to the Apache—to Resolution Copper Mining, LLC, in exchange for over 5,000 acres of private land. The legislation included requirements for tribal consultation, land appraisal, and the preparation of an environmental impact statement (EIS). Following the issuance of a revised Final EIS in 2025, several environmental and tribal groups, as well as individual Apache plaintiffs, challenged the exchange. Their claims spanned the National Environmental Policy Act (NEPA), the National Historic Preservation Act (NHPA), the Religious Freedom Restoration Act (RFRA), and the Free Exercise Clause, alleging procedural and substantive deficiencies.Previously, the United States District Court for the District of Arizona denied the plaintiffs’ motions for a preliminary injunction, finding that they had not demonstrated a likelihood of success on any claims relating to the appraisal process, NEPA, consultation, or the National Forest Management Act. A separate group of Apache plaintiffs brought similar claims, including religious liberty challenges, which were also denied—particularly in light of circuit precedent established in Apache Stronghold v. United States. All plaintiff groups appealed and sought further injunctive relief pending appeal.The United States Court of Appeals for the Ninth Circuit reviewed the district court’s denial for abuse of discretion and affirmed. The court held that plaintiffs had standing and their claims were justiciable, but that none of their arguments were likely to succeed on the merits or raised serious questions. The court specifically found the appraisals and environmental review sufficient, the agency’s tribal consultation adequate, and the religious liberty claims foreclosed by circuit precedent. The denial of a preliminary injunction was affirmed, and all related motions for injunctive relief were denied as moot. View "ARIZONA MINING REFORM COALITION V.

The case concerns a challenge brought by an environmental non-profit against the U.S. Environmental Protection Agency (EPA) relating to the agency’s 2016 national recommendations for allowable cadmium levels in water. The EPA, as required by the Clean Water Act (CWA), periodically issues nonbinding criteria for water pollutants, which states typically adopt as standards for their own waters. In 2016, the EPA updated its cadmium recommendations but did so without consulting the Fish and Wildlife Service or the National Marine Fisheries Service, as mandated under Section 7 of the Endangered Species Act (ESA) for actions that may affect protected species.Previously, the United States District Court for the District of Arizona found that the Center for Biological Diversity (CBD) had standing to challenge the EPA’s failure to consult. The district court granted summary judgment in favor of CBD, holding that the EPA’s issuance of the cadmium recommendations constituted “agency action” under the ESA that “may affect” listed species, thus triggering the consultation requirement. The court vacated the less stringent chronic freshwater cadmium recommendation and remanded all four 2016 cadmium recommendations to the EPA for proper consultation.On appeal, the United States Court of Appeals for the Ninth Circuit affirmed the district court’s judgment. The Ninth Circuit held that CBD had Article III standing, finding a concrete injury to its members’ interests in protected species, that the injury was fairly traceable to EPA’s recommendations due to predictable state adoption, and that the injury could be redressed by stricter recommendations resulting from consultation. On the merits, the court concluded that EPA’s publication of nationwide recommendations was “agency action” under the ESA and that such action “may affect” listed species, thus requiring prior consultation with the Services. The district court’s vacatur and remand were affirmed. View "CENTER FOR BIOLOGICAL DIVERSITY V. UNITED STATES ENVIRONMENTAL PROTECTION AGENCY" on Justia Law

The Federal Aviation Administration (FAA) introduced new and revised air traffic procedures in the Southern California Metroplex as part of its Next Generation Air Transportation System (NextGen) initiative in 2016, affecting airports including Los Angeles International Airport. These procedures, specifically the HUULL, IRNMN, and RYDRR routes, relied on satellite navigation and were subject to an environmental review, which concluded there would be no significant noise impacts. In 2018, the FAA amended these procedures, making minor changes to altitude and speed restrictions at certain waypoints, with no changes to flight paths, number of flights, or aircraft types. Only one amended waypoint affected Malibu, and none affected Culver City.Previously, Culver City and other parties challenged the FAA’s 2016 approval in the United States Court of Appeals for the District of Columbia Circuit, which upheld the FAA’s decision. After the 2018 amendments, the City of Los Angeles and Culver City (as intervenor) challenged the FAA’s actions in the United States Court of Appeals for the Ninth Circuit, which found violations of environmental statutes but remanded for further review without vacating the procedures. The FAA then conducted additional environmental consultations and issued a Record of Decision, concluding the amendments qualified for a categorical exclusion from further environmental review.The United States Court of Appeals for the Ninth Circuit reviewed the petitions from Malibu and Culver City regarding the FAA’s 2018 amendments. The court held that only challenges to the 2018 amendments were timely, dismissing any challenge to the original 2016 procedures as untimely. The court determined that neither city demonstrated standing to challenge the 2018 amendments: Malibu’s evidence addressed only the 2016 procedures, and Culver City failed to provide evidence of injury. The petitions were dismissed for lack of standing. View "City of Culver City v. Federal Aviation Administration" on Justia Law

The case centers on the United States Bureau of Land Management’s decision to approve a contract with JS Livestock for a new off-range corral on private land near Winnemucca, Nevada, intended to house and care for up to 4,000 wild horses and burros removed from public lands. Friends of Animals, an advocacy group, challenged this decision, arguing that the Bureau’s actions violated both the Wild Free-Roaming Horses and Burros Act and the National Environmental Policy Act. The group raised concerns about the adequacy of animal welfare protections and environmental impacts, including the facility’s design, animal density, disease management, and mitigation of adverse effects on soil and groundwater.Prior to this appeal, the United States District Court for the District of Nevada reviewed cross-motions for summary judgment. The district court found no statutory violations, holding that the Bureau had complied with both the Wild Horses Act and NEPA. Specifically, the court determined that the Bureau’s reliance on its established animal welfare standards and contract requirements was reasonable and that the environmental assessment sufficiently considered the project’s impacts as required by law. The court granted summary judgment in favor of the Bureau and denied Friends of Animals’ motion.The United States Court of Appeals for the Ninth Circuit reviewed the district court’s decision de novo. The appellate court affirmed the lower court’s ruling, holding that Friends of Animals had representational standing to bring the case. The court found that the Bureau did not abuse its discretion or act contrary to law: it properly ensured humane treatment of the animals, took a “hard look” at environmental impacts as required by NEPA, reasonably relied on compliance with state permits, considered appropriate project alternatives, and adequately explained why the facility’s impacts would not be significant. The summary judgment for the Bureau was affirmed. View "FRIENDS OF ANIMALS V. BURGUM" on Justia Law

A group of 169 individuals who worked at the Clark County Government Center in Las Vegas brought claims alleging that they suffered serious injuries due to exposure to toxic chemicals, including polychlorinated biphenyls (PCBs), at their workplace. The site of the Government Center had previously been used as a rail yard by Union Pacific Railroad, and plaintiffs alleged that Union Pacific dumped waste, including PCBs manufactured by the former Monsanto Company, at the site. Plaintiffs asserted that Monsanto’s corporate successors inherited liability for harms caused by the production, sale, and distribution of PCBs, which allegedly caused a range of health issues for those exposed.The plaintiffs initially filed suit in Nevada state court against multiple defendants, including Union Pacific, the Las Vegas Downtown Redevelopment Agency, and Monsanto’s successors. The claims sought compensatory and punitive damages for injuries stemming from the alleged contamination. Monsanto’s successors removed the action to the United States District Court for the District of Nevada under the Class Action Fairness Act (CAFA). The plaintiffs moved to remand the case back to state court, and the District Court granted the motion, finding that the local controversy exception to CAFA applied since the alleged injuries were localized to Clark County.On appeal, the United States Court of Appeals for the Ninth Circuit reviewed the district court’s remand order de novo. The Ninth Circuit held that CAFA’s local controversy exception did not apply because the principal injuries resulting from Monsanto’s conduct were not shown to have been incurred primarily in Nevada. The court found that plaintiffs’ allegations described nationwide distribution and harm from PCBs, with no facts indicating that Nevada experienced principal or unique injuries. Therefore, the Ninth Circuit reversed the District Court’s order remanding the case and ordered the case to proceed in federal court. View "EMPLOYEES AT THE CLARK COUNTY GOVERNMENT CENTER V. MONSANTO COMPANY" on Justia Law

Several environmental organizations sued a California county, alleging that the county’s operation of the Lopez Dam and Reservoir had harmed the threatened South-Central California Coast steelhead trout by altering water flows and degrading downstream habitat. The steelhead population in Arroyo Grande Creek depends on high, pulsing freshwater flows for migration and spawning, but the dam’s operational schedule reduced these flows, impeded migration, and facilitated predatory species’ access to the creek. The plaintiffs claimed that these practices violated the Endangered Species Act (ESA) by causing unlawful “take” of steelhead and also breached California Fish & Game Code section 5937, which requires dam operators to maintain fish in “good condition.” The creek is also home to two other ESA-listed species: the California red-legged frog and the tidewater goby.The United States District Court for the Central District of California granted a mandatory preliminary injunction, compelling the county to take affirmative actions such as changing flow releases and implementing new habitat protection measures. The court ordered the county to consult with federal agencies about these measures but did not specifically weigh the potential harm to the frog and goby, which the county argued might result from the new water release schedule. Both sides presented competing expert evidence on the impact to all three species.On appeal, the United States Court of Appeals for the Ninth Circuit vacated the preliminary injunction and remanded the case. The appellate court held that when mandatory injunctive relief under the ESA could benefit one protected species while potentially harming another, the district court must consider the balance of equities and public interest as they relate to the other listed species. The court clarified that this balancing does not include economic or developmental interests but is limited to the welfare of other endangered or threatened species. Because the district court had not conducted this analysis, the injunction was vacated for further proceedings. View "SAN LUIS OBISPO COASTKEEPER V. COUNTY OF SAN LUIS OBISPO" on Justia Law
