State AGs Sue Trump ESA Rules: Challenge Weakened Species Protections

• A coalition of state attorneys general has filed two lawsuits challenging the Trump administration's revisions to the Endangered Species Act.
• The lawsuits target three specific rule changes impacting the definition of "harm," critical habitat designations, and protections for newly listed threatened species.
• Plaintiffs, including California and Washington, argue the new rules unlawfully weaken species protections and violate the ESA, APA, and NEPA.
• The attorneys general are seeking a federal court order to vacate the contested regulations.
• California Attorney General Rob Bonta highlighted the need for federal law to protect over 300 species in his state, many of which cross state lines.

This multi-state litigation directly challenges significant changes to the Endangered Species Act, a landmark environmental law enacted over five decades ago.

On a recent Wednesday, a coalition of state attorneys general initiated legal action against the Trump administration, challenging significant revisions to the Endangered Species Act (ESA). These officials contend that the modifications unlawfully diminish safeguards for both endangered and threatened species. The legal offensive comprises two distinct lawsuits, specifically targeting new regulations finalized by the U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service.

Among the states leading this challenge are California and Washington, whose legal representatives assert that the administrative changes are both unlawful and morally indefensible. The core of their argument centers on three key areas where the Trump administration's rules altered existing ESA provisions: the definition of “harm” to a species, the designation of critical habitats, and the protective measures afforded to species classified as threatened. Washington state Attorney General Nick Brown publicly declared that these rule changes are fundamentally flawed, lacking legal, moral, and substantive merit. The plaintiffs are seeking a federal court order from the Northern District of California to vacate these final rules entirely.

The first contested alteration concerns the definition of “harm,” a crucial component of the ESA. The revised rule, according to the state attorneys general, weakens the statute's ability to protect essential breeding and feeding grounds, as well as to mitigate impacts from pollution and habitat degradation. California Attorney General Rob Bonta criticized this particular change as being “illegal, unscientific and contrary to common sense,” suggesting a departure from established environmental principles.

A second significant point of contention involves the habitat exclusion rule, which now permits, and in some instances mandates, the USFWS to exclude certain areas from critical habitat designation. This exclusion can be based on considerations of third-party costs and other regulatory burdens. Critics argue this provision will inevitably reduce the total amount of shielded habitat, thereby impairing the USFWS's capacity to effectively protect and aid endangered species. Attorney General Bonta specifically noted the absence of scientific justification for this particular modification by the Trump administration.

The third challenged revision pertains to the 4(d) rule, which previously provided automatic protections for newly listed threatened species. The Trump administration's rule repealed these blanket safeguards, instead requiring the USFWS to adopt species-specific protections. However, the new framework imposes no deadline or obligation for the agency to actually implement these individualized rules. Furthermore, the USFWS is now required to assess economic impacts before enacting any species-specific regulations. Attorney General Bonta highlighted that the Trump administration offered no rationale for this particular change, underscoring his concerns with a quote from Immanuel Kant: “We can judge the heart of a man by his treatment of animals.”

This multi-state litigation directly challenges significant changes to the Endangered Species Act, a landmark environmental law enacted over five decades ago. The AGs argue that the Trump administration's revisions threaten the protections for thousands of species, including iconic examples like the bald eagle, grizzly bear, and humpback whale. Their legal arguments assert that the new rules violate not only the ESA itself but also the Administrative Procedure Act (APA) and the National Environmental Policy Act (NEPA), forming a comprehensive APA NEPA ESA litigation challenge.

California, one of nearly two dozen states participating in these lawsuits, has a substantial stake, with over 300 species, such as the Western bumblebee and blue whale, protected under the federal act within its borders. California Attorney General Rob Bonta emphasized that while his state possesses its own version of the Endangered Species Act, federal law is indispensable for species that traverse state lines, underscoring the interconnectedness of ecosystems. He vividly described the situation as a “delicate game of Jenga,” highlighting the fragility of species protection.

Washington state Attorney General Nick Brown, speaking alongside Bonta, characterized the original Endangered Species Act as a bipartisan achievement and a testament to the collective wisdom of the American populace. He recalled that before the ESA's implementation, many once-common species faced imminent extinction. The attorneys general are collectively seeking a judicial order to vacate the contested rules, aiming to restore the prior level of protection for endangered and threatened species across the nation.

This multi-state litigation directly challenges significant changes to the Endangered Species Act, potentially impacting environmental compliance, land use, and project development if the Trump-era rules are vacated. Lawyers and compliance officers should closely monitor this case to understand evolving regulatory requirements for species protection and critical habitat designations.
