An order of revocation or suspension or placing a license on probationary status or other disciplinary action as the Department may consider proper or a certified copy thereof, over the seal of the Department and purporting to be signed by the Secretary, shall be prima facie proof that:
         1. the signature is the genuine signature of the
    
Secretary;
        2. the Secretary is duly appointed and qualified; and
         3. the Board and the members thereof are qualified to
    
act.
Such proof may be rebutted.
