Guidance Clarity Act of 2025

If passed, the bill would likely increase litigation challenging agency guidance and interpretations, similar to patterns seen after the Supreme Court's Marbry v. Madison doctrine limited Chevron deference (2024) and the decision in United States v. Skidmore (2003) that agencies' interpretations are entitled to respect but not binding deference. Regulated industries would have stronger arguments that they can disregard agency guidance pending litigation. Federal agencies would need to pursue formal notice-and-comment rulemaking for matters previously addressed through guidance, slowing implementation and creating compliance gaps. States and industries that benefit from clear regulatory standards (e.g., electric utilities navigating EPA guidance, healthcare providers following CMS guidance) would face increased uncertainty. This aligns with broader Republican efforts to constrain agency power through requirements like the REINS Act and limitation on major questions doctrine expansions.
