Sunset Chevron Act

HR 274, the Sunset Chevron Act, requires the Government Accountability Office (GAO) to compile a list of federal court decisions that upheld agency rules using Chevron deference (a judicial practice deferring to agency interpretations of laws) and are still in effect. The bill mandates that the GAO publish this list within 180 days of enactment, organizing it by agency and assigning each rule a sunset date. The most recent rule from each agency expires 30 days after the list's publication, with earlier rules expiring 30 days after the prior rule’s sunset date. This creates an automatic expiration process for specific agency rules upheld under Chevron deference, directly affecting federal agencies whose rules are included in the GAO's list.
