Neither the commissioner nor any deputy or employee shall during the commissioner’s, deputy’s, or employee’s tenure of office be an officer, agent, or employee of an insurer or directly or indirectly interested in any insurer or licensee under this code, except (a) as a policyholder or (b) by virtue of relationship by blood or marriage to any person interested in any insurer or licensee.
