A license may be granted, renewed, continued in effect, suspended or revoked subject to any reasonable condition which effectuates the provisions of this part; provided such condition pertains to the subject matter of a hearing held under this part. In any case in which an appeal has been taken from a ruling of the Commissioner of Agriculture revoking or refusing to renew or transfer a license and a stay has been obtained as hereinafter provided for, nothing herein shall preclude the commissioner from renewing or transferring the license of such dealer for a subsequent license period, conditioned that if such appeal is not sustained the license shall thereby be automatically terminated.
