Gundy v. United States was a case involving a fairly obscure statute regulating sex offenders, but some have seen it as a harbinger of the destruction of the modern administrative state. In a 4-1-3 split, the Court turned away a constitutional challenge based on a claim that Congress had delegated too much authority to the executive branch. But there were ominous signs that at least four Justices are willing to change the ground rules in order to slash the authority of administrative agencies. What we don't know yet is whether they can get a fifth vote, and how far they are willing to go.

The issue before the Court was whether the statute was an unconstitutional delegation of legislative power to the Attorney General. For almost 90 years, the test has been whether a statute contains an "intelligible principle" limiting executive discretion …

The EPA released its finalized rule for carbon emissions from existing power plants last week. The agency calls the rule the "Affordable Clean Energy" (ACE) rule, but it would be better named the "Advancing Coal Energy" rule given its explicit aim to keep old, dirty coal-fired power plants running.

A bit of background first for those who aren't familiar with the rule. The United States has made a great deal of progress cleaning up its power plants so they emit less air pollution – not just carbon dioxide, but also particulate matter, sulfur dioxide, and other damaging pollutants. But much of the remaining air pollution comes from older power plants built before health-promoting clean air regulations were in place. Pollution from coal plants alone accounts for one-quarter of the value of all environmental damage in the United States, and all power plant pollution contributes to approximately 52,000 …

On June 21, the Environmental Protection Agency (EPA) released its evaluation of the third and final round of state Watershed Implementation Plans (WIPs) under the Chesapeake Bay restoration framework known as the "Bay TMDL" (Total Maximum Daily Load). EPA's evaluation of the seven Bay jurisdictions broke no new ground regarding the quality or contents of the states' plans, but instead reiterated many of the same findings and concerns expressed by advocates, including the ones I expressed with my colleague David Flores. So what, if anything, is EPA going to do about the many shortcomings in the state WIPs?

From the looks of it, not nearly enough. The first indication that EPA's evaluation was not going to be a satisfactory response to the problematic WIPs was buried in a footnote. In the second footnote on the first page of each of the WIP evaluations, EPA says that it …

The Supreme Court has concluded that Virginia's decades-old moratorium on uranium mining is not pre-empted by the Atomic Energy Act. But there is no clear answer to the question that pervaded the briefing and oral argument: What is the proper role for state legislative purpose in a pre-emption analysis?

Monday's judgment was accompanied by three opinions: a lead opinion written by Justice Neil Gorsuch and joined by Justices Clarence Thomas and Brett Kavanaugh; a concurring opinion by Justice Ruth Bader Ginsburg, joined by Justices Sonia Sotomayor and Elena Kagan; and a dissenting opinion by Chief Justice John Roberts, joined by Justices Stephen Breyer and Samuel Alito. The Gorsuch opinion stated that state legislative purpose has no place in pre-emption analyses, whereas the Ginsburg opinion expressed discomfort …

In a recent essay posted to SSRN, I try to see, and to appreciate, the wisdom in a species of climate litigation that has many detractors. This litigation asks the courts to hold the government and private parties judicially accountable for their active promotion and pursuit of climate-endangering activities, even after they knew better – even after they knew the terrible risks we faced if they continued on their preferred course. It calls upon venerable legal doctrines, deployed as modern bulwarks against the most pressing challenge of our time.

The legal theories these lawsuits pursue do not come from statutes, but instead rely on constitutional law, natural law, and the common law. This is the kind of litigation that is most likely to draw criticism not only from the governmental and industrial institutions it seeks to constrain, but from within the environmental community itself, as some worry that …

When a facility installs and operates the required pollution control equipment, we normally think of the pollution problem as solved. But there still may be bursts of pollution associated with start-up, shut-down, accidents, or external events. A recent study of pollution in Texas shows that these events have substantial health impacts, involving significant deaths and overall costs of about a quarter billion dollars a year in that state. Ironically, the study comes out at the same time as Trump's EPA has proposed to approve Texas's lax treatment of these "exceptional events." Texas purports to bar federal courts from even considering civil penalties for permit violations due to those events.

These events may be exceptional, but that does not make them harmless. The study by researchers at the University of Indiana proved that excess emissions from exceptional events impact public health. According …

The Trump administration's hostile attitude toward science has continued unabated. The administration has used a triad of strategies: efforts to defund research, suppression of scientific findings, and embrace of fringe science.

1. Budget. The administration continues to favor deep cuts in research support. Its initial 2020 budget proposal calls for a 13 percent cut to the National Science Foundation, a 12 percent cut at the National Institutes of Health, and elimination of the Energy Department's research support for advanced energy technologies (ARPA-E) and EPA's climate change research office. The proposal would also eliminate funding for the Sea Grant program, which funds environmental research on the coasts. The budget proposal is unlikely to become law, given that similar proposals were rejected even when the Republicans controlled both houses of Congress. But they are indicative of the administration's values.  
2. Toxic chemical risks. A report by …
