Has the Supreme Court Declared Open Season on Interstate Commerce?

How to read a baffling Supreme Court ruling.

If you’re a lawyer or a lower court judge, you know you’ve got a problem when the Supreme Court’s opinion begins with a list of parts of the opinion that do or don’t have a majority, along with a list of what different permutations of judges said what about the issues.   The Pork Producers case …

The Biden Power Plant Rule and the Major Question Doctrine

The new rule has hardly any of the features that caused the Supreme Court to strike down the Obama rule.

We’ve already started to hear claims that the Biden power plant rule falls under the major question doctrine, which the Supreme Court used to strike down Obama’s Clean Power Plan. Are those claims plausible? Consider the aspects of the Clean Power Plan that the Supreme Court found objectionable. I’ve identified eight factors that the Court …

Taming the Dormant Commerce Clause

A new Supreme Court opinion is good news for state climate regulators.

Although the Constitution does not say so directly, the Supreme Court has said there are implied limits on state regulations that interfere with interstate commerce.. This is known as the dormant commerce clause doctrine.  State clean energy laws have been bedeviled by challenges based on this doctrine. The Supreme Court has just made it easier …

Justices Decline to Intervene in Government Lawsuits Seeking Damages from Fossil Fuel Industry

The Car Rule and the Major Questions Doctrine

Claims that the new rule violates the doctrine are groundless.

Ever since the Supreme Court decided West Virginia v. EPA, conservatives and industry interests have claimed that just about every new regulation violates the major question doctrine.

Unprecedented Legal Questions

The climate crisis is unprecedented. So is its legal fallout.

In teaching my class on Climate Law, I’ve been struck by how many new legal questions courts are confronting as a result of the climate crisis.  Dealing with these new legal questions is going to put stress on existing legal doctrines and require courts to rethink some basic principles.  Unfortunately, the Supreme Court is pushing …

When Is It Legal to Consider Race in Regulating?

Two upcoming Supreme Court decisions will tell us a lot about the answer.

On Halloween, the Supreme Court heard oral argument in cases brought by Students for Fair Admissions (SFFA) against Harvard and UNC. These cases seem likely to move the Court closer to requiring colorblindness. How would that impact EPA’s ability to pursue environmental justice?

Do Climate Change Cases Belong in Federal Court? The Biden Administration Weighs In.

In a very narrowly argued brief, the Administration calls for returning the cases to state court.

The Biden Administration, at the Supreme Court’s invitation, has now filed a brief giving its views about current lawsuits against oil companies. The gist of the brief is that the cases belong in state court., and that the Court should let that happen rather than stepping into the litigation. The brief is right about that, …

Defending clean car regulations and tracking judicial decision-making

Last June, the Supreme Court formally unveiled the “major questions” doctrine in the landmark environmental case West Virginia v. EPA. In rejecting EPA’s plan to regulate greenhouse gas emissions from existing power plants under Section 111(d) of the Clean Air Act, the Court stated that “agency decisions of vast economic and political significance” (i.e., those …
