(a) Any insurer which precipitates, or aids in precipitating or conducting a rate war and by so doing writes or issues a policy of insurance at a less rate than permitted under its schedules filed with the Commissioner, or below the rate deemed by him to be proper and adequate to cover the class of risk insured, shall have its certificate of authority to do business in this territory suspended until such time as the Commissioner is satisfied that it is charging a proper rate of premium.
(b) Any insurer which has precipitated, or aided in precipitating or conducting a rate war for the purpose of punishing or eliminating competitors or stifling competition, or demoralizing the business, or for any other purpose, and has ordered the cancellation or rewriting of policies at a rate lower than that provided by its rating schedules where such rate war is not in operation, and has paid or attempted to pay to the insured any return premiums, on any risk so to be rewritten, on which its agent has received or is entitled to receive his regular commission, such insurer shall not be allowed to charge back to such agent any portion of his commission on the ground that the same has not been earned.
