Case Summary Citation

Center for Biological Diversity v. U.S. Bureau of Land Management, 141 F.4th 976 (9th Cir. 2025)

Abstract

The Ctr. for Biological Diversity v. U.S. Bureau of Land Mgmt. marks the Ninth Circuit’s second time considering the Willow Project, which plans to drill oil in Alaska. Environmental plaintiffs brought a series of claims under NEPA, the Reserves Act, ANILCA, and the ESA to stop or stall the Project. Plaintiffs focused on the BLM’s use of a “full field development standard” in assessing alternatives to the Project. Despite the range of claims, the Ninth Circuit allowed the Project to move forward, but on remand required the BLM to explain its reasoning for departing from the full field development standard in the 2023 Record of Decision.
