The Supreme Court has granted certiorari in a case that could fundamentally reshape the federal government's regulatory authority. The case challenges the Environmental Protection Agency's power to issue broad environmental rules without explicit congressional authorization, building on the major questions doctrine established in recent terms.
Legal scholars say the case could extend the Court's recent trend of limiting administrative agency discretion and requiring Congress to speak more clearly when delegating regulatory power. The outcome could affect agencies across the government, from the SEC to the Department of Labor.
Oral arguments are scheduled for the October 2026 term, with a decision expected by June 2027. Business groups have filed amicus briefs supporting the challenge, while environmental and consumer organizations warn of far-reaching consequences for public health protections.
