A license which has expired for failure of the holder to renew may be late renewed after application and payment of the prescribed late renewal fee within the time period established by the board and provided the applicant meets such requirements as the board may establish by rule. Any license which has not been renewed by the end of the late renewal period shall be considered revoked and subject to reinstatement at the discretion of the board after meeting such requirements as the board may establish. see full law
