CHPS Podcast Episode 8: What the Supreme Court's Tariff Decision Means for Environmental Regulation

April 1, 2026

In Episode 8 of CHPS of Insight, host Chris White welcomed Jerry Worsham from Clark Hill’s Environmental & Natural Resources practice to discuss the recent Supreme Court decisions and their potential ramifications for environmental law and policy in the United States.

The Supreme Court’s Recent Decision: A Closer Look

In the podcast, White and Worsham got into an analysis of the recent ruling by the Supreme Court, where the court overturned former President Trump’s use of International Emergency Economic Powers Act (IEEPA) tariffs. Worsham explained that the decision was largely influenced by the major questions doctrine, a principle that asserts significant regulatory actions require clear congressional authorization. This move has resonated deeply with environmental lawyers, given its foundation in cases like West Virginia vs. EPA, which also challenged federal authority and scope.

The Demise of Chevron Deference

Worsham discussed another pertinent legal shift: the waning influence of Chevron deference. Historically, Chevron deference allowed courts to rely heavily on federal agencies’ interpretations of statutes they administer, giving agencies an upper hand. However, the Supreme Court’s recent decisions have leveled the playing field, empowering attorneys to offer stronger challenges to agency regulations that overstep legislative boundaries.

Environmental Practices in Transition

With changes in legal interpretation and doctrine, the environmental regulatory landscape is poised for transformation. Worsham noted the rescinding of the endangerment finding by the Trump administration as a crucial development. This finding, originally established under the Obama administration, underpinned climate change and greenhouse gas regulations. Now, with its rescindment already being litigated, the major questions doctrine could again play a pivotal role.

Looking Forward: Challenges and Opportunities

For environmental attorneys, the evolving judicial landscape presents both challenges and opportunities. Worsham suggested that future court battles will likely continue to stress the need for concerted arguments combining both the major questions doctrine and textualist interpretations of statutory language—a nod to Justice Scalia’s influence on statutory interpretation. As policy and legal frameworks adapt to new Supreme Court interpretations, stakeholders in both environmental and broader regulatory arenas must brace for dynamic shifts.
