(1) The reasonableness of any rule or regulation in its application to subscribers, or the refusal of any rating organization to admit an insurer as a subscriber, shall, at the request of any subscriber or any such insurer, be reviewed by the commissioner at a hearing held upon notice to the rating organization and to the subscriber or insurer.

(2) If the commissioner finds that a rule or regulation is unreasonable in its application to subscribers, the commissioner shall order that the rule or regulation is not applicable to subscribers that are not members of the rating organization.

(3) If a rating organization fails to grant or reject an insurer's application for subscribership within thirty days after it was made, the insurer may request a review by the commissioner as if the application had been rejected. If the commissioner finds that the insurer has been refused admittance to the rating organization as a subscriber without justification, the commissioner shall order the rating organization to admit the insurer as a subscriber. If the commissioner finds that the action of the rating organization was justified, the commissioner shall make an order affirming its action.
