A federal appeals court has ruled that the White House's Council on Environmental Quality (CEQ) lacks the authority to issue binding regulations under the National Environmental Policy Act (NEPA), overturning over 46 years of environmental regulations. This ruling came in the case of Marin Audubon Society, et al v. FAA, et al, where the DC Circuit Court of Appeals determined that the CEQ cannot impose binding NEPA regulations. The decision, made by a three-judge panel, has significant implications for federal agencies, which are now expected to have more flexibility in complying with NEPA. Additionally, the ruling has raised substantial questions about the future enforcement of environmental regulations.
