Idaho Code § 54-1917
After suspension or revocation of the license upon any of the grounds set forth in this chapter, the administrator may renew the license upon proof of compliance by the contractor with all provisions of the decision as to renewal or, in the absence of such decision or any provisions therein as to renewal, in the sound discretion of the administrator. After revocation of a license upon any of the grounds set forth in this chapter, the license shall not be renewed or reissued within a period of one (1) year after the final decision of revocation and then only on proper showing that all loss caused by the act or omission for which the license was revoked has been fully satisfied and that all conditions imposed by the decision of revocation have been complied with. At any time before a case is finally submitted to the board for decision, whether upon an original hearing, or upon a rehearing, a complaint or answer may, upon the motion of either party, and with the consent of the board, or upon the board's own motion, be amended. If new charges are alleged in an amended complaint, the defendant may, upon request, be allowed ten (10) days to prepare his defense to such new charges.
