(a) A corporation, an unincorporated association, a partnership or an individual, whether located within or outside this Commonwealth, may make application to the commissioner for license as a rating organization for title insurance companies, and shall file therewith:

(b) Subject to rules and regulations which have been approved by the commissioner as reasonable, each rating organization shall permit any title insurance company not a member to be a subscriber to its rating services. Notices of proposed changes in such rules and regulations shall be given to subscribers. Each rating organization shall furnish its rating services without discrimination to its members and subscribers. The reasonableness of any rule or regulation in its application to subscribers, or the refusal of any rating organization to admit a title insurance company as a subscriber, shall, at the request of any subscriber or any such title insurance company, be reviewed by the commissioner at a hearing held upon at least ten days written notice to such rating organization and to such subscriber or title insurance company. If the commissioner finds that such rule or regulation is unreasonable in its application to subscribers, he shall order that such rule or regulation shall not be applicable to subscribers. If the rating organization fails to grant or reject an application of a title insurance company for subscribership within thirty days after it was made, the title insurance company may request a review by the commissioner as if the application had been rejected. If the commissioner finds that the title insurance company has been refused admittance to the rating organization as a subscriber without justification, he shall order the rating organization to admit the title insurance company as a subscriber. If he finds that the action of the rating organization was justified, he shall make an order affirming its action.

(c) Cooperation among rating organizations, or among rating organizations and title insurance companies, and concert of action among title insurance companies under the same general management and control in rate making or in other matters within the scope of this article is hereby authorized, provided the filings resulting therefrom are subject to all the provisions of this article which are applicable to filings generally. The commissioner may review such activities and practices and if, after a hearing, he finds that any such activity or practice is unfair or unreasonable or otherwise inconsistent with the provisions of this article, he may issue a written order specifying in what respects such activity or practice is unfair or unreasonable or otherwise inconsistent with the provisions of this article and requiring the discontinuance of such activity or practice.
