IDAHO ADMINISTRATIVE PROCEDURE ACT – Amends existing law to establish provisions regarding temporary rules and to revise provisions regarding temporary rules.

This Idaho bill (H 539) amends the Administrative Procedure Act to tighten rules for temporary agency regulations. It requires the governor to justify using temporary rules only during emergencies (like public health threats, natural disasters, or urgent compliance deadlines), with a written explanation published alongside the rule. Agencies must also immediately begin drafting permanent rules while the temporary rule is in effect, and cannot reuse the same temporary rule without a new emergency justification or waiting 90 days. The bill directly affects state agencies and the governor, ensuring temporary rules are narrowly limited and transitioned to permanent rules promptly.
