Sunset Chevron Act

Summary

Requires the Government Accountability Office (GAO) to publish a list of all currently effective federal rules that courts upheld based on Chevron deference and to assign each such rule a staggered sunset date so they expire in 30‑day steps by agency. It also removes the special 60‑day congressional review window used to file disapproval resolutions under the Congressional Review Act for those listed rules, while leaving other CRA procedures in place. The GAO must publish the list within 180 days of enactment; the most recent rule for each agency will be set to expire 30 days after publication, with earlier rules for that agency expiring in successive 30‑day intervals. The change creates immediate deadlines for many existing rules and narrows one mechanism Congress uses to disapprove rules under the CRA.

• GAO must publish, within 180 days, a list of all currently effective federal rules that courts upheld based on Chevron deference.
• For each agency, the most recent listed rule will expire 30 days after publication; earlier rules for that agency expire in successive 30‑day steps.
• The 60‑day CRA filing window for joint disapproval resolutions does not apply to rules on the GAO list, though other CRA provisions still apply.
• The law creates an automatic, agency‑by‑agency staggered expiration schedule that can remove existing rules without new rulemaking.
• Agencies, regulated entities, and courts face increased uncertainty and potential administrative burden as rules approach assigned sunset dates.
• GAO bears the responsibility and workload to identify qualifying court decisions and compute sunset dates.
• The statute may prompt litigation over GAO’s list, the sunset calculations, and the interaction with existing administrative law protections.
• The law does not itself appropriate funds, change tax law, or alter substantive standards of judicial review beyond the listing mechanism.
