What’s this? A bonus Opinionpalooza episode for one and all? That’s right! The hits just keep coming from SCOTUS this week, and two big decisions landed Thursday that might easily get lost in the mix: Ohio v EPA and SEC v Jarkesy. Both cases shine a light on the conservative legal movement (and their billionaire funders’) long game against administrative agencies. In Ohio v EPA, the Court struck down the EPA’s Good Neighbor Rule, making it harder for the agency to regulate interstate ozone pollution. This decision split along ideological lines, and is part of a stealthy dismantling of the administrative state. SEC v Jarkesy severely hinders the agency’s ability to enforce actions against securities fraud without federal court involvement, and the decision will affect many other agencies. In her dissent, Justice Sonia Sotomayor pointed out how this power grab by the court disrupts Congress's ability to delegate authority effectively. Project 2025 just got a jump start at SCOTUS, and we have two more big administrative cases yet to come, the so-called Chevron cases: Loper Bright v Raimondo and Relentless, Inc. v Department of Commerce. This is shaping up to be a good term for billionaires and a court apparently hungry to expand its power. Dahlia Lithwick is joined by Slate’s own Mark Joseph Stern (of course) and they are saved from any regulatory confusion by environmental and administrative law all-star, Lisa Heinzerling, the Justice William J. Brennan, Jr., Professor of Law at the Georgetown University Law Center, who served in the EPA under President Obama.  This is part of Opinionpalooza, Slate’s coverage of the major decisions from the Supreme Court this June.
