Idaho Admin. Code r. 37.01.01.760
A hearing officer issuing a recommended or preliminary order may modify the recommended or preliminary order on the hearing officer's own motion within fourteen (14) days after issuance of the recommended or preliminary order by withdrawing the recommended or preliminary order or by issuing a substitute recommended or preliminary order. The agency head may modify or amend a final order of the agency (be it a preliminary order that became final because no party challenged it or a final order issued by the agency head itself) at any time before notice of appeal to District Court has been filed or the expiration of the time for appeal to District Court, whichever is earlier, by withdrawing the earlier final order or by substituting a new final order for it.
