Section 52D. Any member of or subscriber to a rating organization may appeal to the commissioner from the action or decision of such rating organization in approving or rejecting any proposed change in or addition to the filings of such rating organization and the commissioner shall, after a hearing held upon not less than ten days' written notice to the appellant and to such rating organization, issue an order approving the action or decision of such rating organization or directing it to give further consideration to such proposal, or, if such appeal is from the action or decision of the rating organization in rejecting a proposed addition to its filings, he may, in the event he finds that such action or decision was unreasonable, issue an order directing the rating organization to make an addition to its filings, on behalf of its members and subscribers, in a manner consistent with his findings, within a reasonable time after the issuance of such order. In deciding such appeal the commissioner of insurance shall apply the standards set forth in section fifty-two.
Every rating organization and every insurer which makes its own rates shall, within a reasonable time after receiving written request therefor and upon payment of such reasonable charge as it may make, furnish to any insured affected by a rate made by it, or to the authorized representative of such insured, all pertinent information as to such rate. Every rating organization and every insurer which makes its own rates shall provide within the commonwealth reasonable means whereby any person aggrieved by the application of its rating system may be heard, in person or by his authorized representative, on his written request to review the manner in which such rating system has been applied in connection with the insurance afforded him. If the rating organization or insurer fails to grant or reject such request within thirty days after it is made, the applicant may proceed in the same manner as if his application had been rejected. Any party affected by the action of such rating organization or such insurer on such request may, within thirty days after written notice of such action, appeal to the commissioner, who, after a hearing held upon not less than ten days' written notice to the appellant and to such rating organization or insurer, may affirm or reverse such action.
