Topline

Congress should codify and expand on the recent changes to judicial review made in Loper Bright Enterprises v. Raimondo that clarified that courts need not give deference to federal agencies’ interpretations of ambiguous statutes.

Background

The Founders intended for Congress to make laws, the executive branch to enforce them, and the judicial branch to interpret them. That model limits the centralization of government power by allowing the branches to act as checks against any branch that encroaches on the others’ constitutional powers. The separation of powers has been under some strain since Depression-era realignments concentrated expansive regulatory powers in executive branch agencies.

Congress enacted the Administrative Procedure Act (APA) in 1946 to put guardrails on often unaccountable agencies, requiring notices of proposed rulemaking and public comment periods, and establishing a judicial review process for challenged rules. However, Chevron v. NRDC (1984) tilted the APA’s judicial review process in favor of agencies’ discretion, holding that courts should defer to agencies’ “reasonable” interpretations on matters where the statute is ambiguous. But in Loper Bright Enterprises v. Raimondo (2024), the Supreme Court held that courts must “exercise their independent judgment in deciding whether an agency has acted within its statutory authority.” Loper Bright instructed courts to give “respectful consideration” to executive branch interpretations, though it was silent on the separate question of whether courts should defer to agencies’ interpretations of ambiguities in rules they’ve written.

Action Items (Congress)

How It Would Make Life More Affordable

Related Legislation: SOPRA Act (S. 33, H.R. 1605); Regulatory Accountability Act (S. 1708, H.R. 3525).

Bottomline

Congress and the courts should ensure that agencies stick to enforcing the law as written.
