A plea or verdict of guilty or a conviction following a plea of nolo contendere made to a charge of a felony or of any offense which is substantially related to the qualifications, functions, or duties of the business or profession to which the license was issued is deemed to be a conviction within the meaning of this chapter. The board may order the license suspended or revoked, or shall decline to issue a license when the time for appeal has elapsed, or the judgment of conviction has been affirmed on appeal or when an order granting probation is made suspending the imposition of sentence, irrespective of a subsequent order under the provisions of Section 1203.4 of the Penal Code allowing such person to withdraw his or her plea of guilty and to enter a plea of not
guilty, or setting aside the verdict of guilty, or dismissing the accusation, information, or indictment.
