States Sue Trump Administration Over Weakened Endangered Species Protections

Core Event: Lawsuits Challenge 2024 ESA Rule Changes
On September 9, Democratic attorneys general from 20 states and the District of Columbia filed two federal lawsuits alleging that the Trump administration illegally weakened the federal Endangered Species Act (ESA). The suits target a rule that narrows the ESA’s definition of “harm” and two additional rules that strip automatic protections from newly threatened species unless case-by-case safeguards are issued, and require the government to consider industry objections before designating “critical habitat.” The lawsuits name the U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) as defendants.
Background: ESA’s Legacy and Recent Revisions
Enacted by Congress in 1973, the ESA has been credited with preventing the extinction of species such as the bald eagle, California condor, grizzly bear and humpback whale. Historically, “harm” under the ESA included habitat degradation that interfered with breeding, feeding or shelter. On July 14, the Department of the Interior revised the definition so that “harm” applies only to actions that directly injure or kill listed wildlife, allowing activities like oil drilling or mining to proceed in habitats so long as they do not cause immediate death or injury.
Key Rule Changes at Issue
1. Narrowed “harm” definition – limits protection to direct injury or death, excluding indirect habitat impacts.
2. Elimination of blanket protections for newly threatened species – requires the USFWS to issue species-specific rules before any protection applies.
3. Critical-habitat decision-making – mandates that objections from developers, fossil-fuel companies and other businesses be weighed before an area is designated as critical habitat.

- Defendants: USFWS (Department of the Interior) and NMFS (Department of Commerce).

What’s Next
The lawsuits seek injunctions to halt enforcement of the three rules and request a judicial declaration that the agency actions violate the Administrative Procedure Act and the National Environmental Policy Act. The cases are pending in federal court; no decision date has been set.
