A recent Ninth Circuit case requires states to do more to achieve clean air goals.

Last week, the Ninth Circuit decided Committee for a Better Arvin v. EPA, which is both a significant air pollution case and an interesting case study in how the Supreme Court has changed judicial review of agency actions. Applying what it considered to be the best interpretation of an ambiguous statute, the Court required tougher air pollution controls for the San Joaquin Valley. The dissent argued that the decision would be a disaster in terms of policy. But is that even relevant under the Loper Bright ruling?

The Color PURPA

A Win for Solar– And a Glimpse of Life After Chevron

The majority in a recent case — an Obama appointeet and a Trump appointee — ruled in favor of renewable energy. Even without Chevron deference, they were able to conclude that the statute favored solar producers. And unlike a win under Chevron, this one can’t be reversed by a more conservative agency — it’s etched in stone.

Precedent, the Trump Administration, and Endangered Species

A new Trump Administration initiative misinterprets the overruling of Chevron

The Trump Administration’s effort to strip away protections under the Endangered Species Act that had previously been upheld by the Supreme Court. The Administration seems to think they’re entitled to ignore that earlier decision because it was decided under the Chevron test and Chevron has since been overruled. They’re wrong. If it wishes to change the existing interpretation, the agency must give a reasoned argument for doing so that discusses the relevant policy issues, including reliance and the impact of its decision on endangered species.

How the US Supreme Court’s recent decisions enable greater reliance on “alternative” facts

Perplexed? Worried? Here’s a guide to a fraught area of law.

If you’re confused about the Supreme Court’s ruling, you’re not alone. Scholars will be discussing the recent ruling for years. It clearly will limit the leeway that agencies have to interpret statutes, meaning less flexibility to deal with new problems. But unlike many commentators, I don’t think the sky is falling. I was teaching environmental …

Is Loper v. Raimondo Really the Power Grab Commentators Assume?

The Supreme Court has already grabbed power from agencies through the major questions doctrine.

Headlines about today’s decision in Loper v Raimondo overturning the 40 year-old decision in Chevron v NRDC that granted agencies deference in their interpretation of ambiguous statutes  focus on the “massive power grab,” the decision’s “sweeping” nature and call it a  “blow” to the administrative state.  My view may be idiosyncratic but I don’t view …

Power Play: The Effects of Overruling Chevron

Who will win and who will lose if Chevron is overruled?

Next week, the Supreme Court will hear oral arguments about whether to overrule the Chevron doctrine.  That doctrine allows administrative agencies that implement statutes to resolve ambiguities in those statutes. Overruling the doctrine would shift that power to courts.  Institutionally, then, judges would be the big winners, with more sway over how laws are implemented. …
