The U.S. Supreme Court's recent decision to overturn Chevron deference – the principle that granted federal agencies leeway in interpreting ambiguous laws – marks a pivotal shift in administrative law. This ruling is part of a broader pattern of Supreme Court decisions reflecting skepticism toward agency authority and heightened scrutiny of environmental regulations. In this episode, Ann Carlson, the Shirley Shapiro Professor of Environmental Law and Co-Director of the Emmett Institute on Climate Change and the Environment at UCLA, joins us to explore the implications of these trends for climate and environmental policies. Together, we examine the role of the Supreme Court in ensuring effective regulation, strategies for navigating this evolving legal landscape, and what these shifts mean for the future of environmental governance in the United States.
