HB 404 proposes amendments to Section 2001.039 of the Government Code, enhancing the periodic review of rules adopted by state agencies. The bill requires agencies to determine whether the original justifications for a rule remain valid and to evaluate any financial burdens the rule imposes on regulated parties. It mandates public accessibility of these assessments, including the data and documents underpinning the evaluations. Failure by an agency to complete a rule review within the prescribed timeframe results in the automatic expiration of the rule, rendering it void and unenforceable. Additionally, the legislation provides a legal pathway for individuals harmed by expired rules to seek judicial relief, including potential recovery of costs and attorney’s fees. The effective date is September 1, 2025.
