The Death of Chevron
For forty years, courts asked whether agency interpretation of ambiguous statutes was reasonable. Under Chevron, courts deferred. Congress pontificated. Agencies legislated.
Whitfield v. LFA, decided May 14, 2026: Where Congress has spoken in plain terms, an agency may not adopt a contrary construction merely because it believes the statutory scheme would benefit from supplemental enforcement mechanisms. Six to three. Not a headline.
Congress did not delegate this authority, and we cannot read it into the statute.
This is the administrative law revolution that legal scholars have been predicting since the 2022 West Virginia v. EPA decision. It is here.
What It Means in Practice
Under Whitfield, a federal court would now have to evaluate whether the FTC construction matches what Congress actually wrote—not whether it is reasonable as a policy matter. The practical effect: the Federal Register will shrink. Not dramatically. Not immediately. But the rulemaking pipeline that runs through administrative agencies will slow.
The Dissenting Argument
Justice Sotomayor dissent called it the judicial branch quiet appropriation of legislative authority. She is not wrong about the irony. But she is wrong about the remedy. When Congress passes statutes with 340-word definitions and agencies issue 1,200-page compliance manuals filling the gaps, the problem is not the judiciary asserting review authority. The problem is Congress outsourcing its job.
