(b) The commissioner shall promulgate legislative rules pursuant to article three, chapter twenty-nine-a of this code prescribing procedures for rating organizations to permit any insurer not a member to become a subscriber to its rating services for any kind of insurance for which it is authorized to act as a rating organization pursuant to this section. Each rating organization shall furnish its rating services without discrimination to its members and subscribers. The reasonableness of any legislative rule in its application to subscribers shall be reviewed by the commissioner upon request of any such subscriber. If the commissioner finds, upon notice and hearing provided pursuant to article five, chapter twenty-nine-a of this code, that such rule or regulation is unreasonable in its application to subscribers, he shall order that such rule is not to be applicable to subscribers and promulgate a revised rule. The denial of any insurer's application for subscribership in contravention of a legislative rule or the failure to approve or deny such an application within thirty days after submission to the rating organization shall be reviewed by the commissioner upon request of the aggrieved insurer. If the commissioner finds, upon notice and hearing provided pursuant to article five, chapter twenty-nine-a of this code, that the insurer has been wrongfully denied subscribership, he shall order the rating organization to admit the insurer as a subscriber.
(c) No rating organization shall adopt any policy or rule the effect of which would be to prohibit or regulate the payment of dividends, savings or unabsorbed premium deposits allowed or returned by insurers to their policy holders, members orsubscribers.
(d) Cooperation among rating organizations or among rating organizations and insurers in rate making or in other matters within the scope of this article or article twenty of this chapter is hereby authorized, provided the filings resulting from such cooperation are subject to all the provisions of this article and article twenty which are applicable to filings generally.
The commissioner may review such cooperative activities and practices. If the commissioner finds, upon notice and hearing provided pursuant to article five, chapter twenty-nine-a of this code, that any such activity or practice is unfair, unreasonable or otherwise inconsistent with the provisions of this article, he shall issue a written order specifying in what respects such activity or practice is unfair, unreasonable or otherwise inconsistent with the provisions of this article, and requiring that such activity or practice be discontinued immediately.
(e) Any rating organization may subscribe for or purchase actuarial, technical or other services, and such services shall be available to all members and subscribers without discrimination.
