The U.S. Supreme Court's recent decisions are reshaping the legal landscape regarding agency deference and diversity initiatives. The Fifth Circuit is reconsidering Nasdaq's board diversity rule, highlighting ongoing scrutiny of diversity, equity, and inclusion (DEI) initiatives in corporate governance. Meanwhile, the Sixth Circuit is set to examine how the Supreme Court's rollback of judicial deference affects a health-care lawsuit. This decision, particularly in the case of 𝘓𝘰𝘱𝘦𝘳 𝘉𝘳𝘪𝘨𝘩𝘵 𝘌𝘯𝘵𝘦𝘳𝘱𝘳𝘪𝘴𝘦𝘴 𝘷. 𝘙𝘢𝘪𝘮𝘰𝘯𝘥𝘰, may open avenues for broader challenges against health agency actions. Additionally, the rollback of Chevron deference is perceived as a setback for a trade group's claims regarding a Department of Labor regulation on retirement advisers, while Tennessee's efforts to reclaim family planning grant money may benefit from this judicial shift. Experts suggest that the demise of Chevron deference could embolden opponents of the Environmental Protection Agency (EPA) as well.
