Washington, other states, the District of Columbia, New York City, and nonprofit organizations that intervened to defend the Biden administration’s amendments to the Council on Environmental Quality (CEQ) National Environmental Policy Act (NEPA) regulations asked the Eighth Circuit Court of Appeals to dismiss as moot the appeal of a district court decision vacating the amendments. They argued that the case no longer presented “a live case or controversy” because CEQ published an interim final rule on April 11, 2025 withdrawing all of its NEPA regulations. The intervenors further argued that the Eighth Circuit should vacate the district court’s judgment. The plaintiff states opposed the motion, and CEQ requested an extension until May 30 to respond.
