EPA, the Supreme Court addressed a “particular and recurring problem: agencies asserting highly consequential power beyond what Congress could reasonably be understood to have granted.” By a 6-3 majority, the Court held that, when a “major question” is involved, the decision on how to regulate rests with Congress and Congress alone. The administrative agency’s regulation is valid only to the extent that it is enacted pursuant to an indisputable delegation of authority from Congress.
