(a) Any person aggrieved by any rate charged, rating plan, rating system, or underwriting rule followed or adopted by an insurer or rating organization may request the insurer or rating organization to review the manner in which the rate, plan, system or rule has been applied with respect to insurance afforded him. Such request may be made by his authorized representative, and shall be in writing. If the request is not granted within thirty days after it is made, the requester may treat it as rejected. Any person aggrieved by the action of an insurer or rating organization in refusing the review requested, or in failing or refusing to grant all or part of the relief requested, may file a written complaint and request for hearing with the Insurance Commissioner, specifying the grounds relied upon. If said commissioner has information concerning a similar complaint he may deny the hearing. If he believes that probable cause for the complaint does not exist or that the complaint is not made in good faith he shall deny the hearing. Otherwise, and if he finds that the complaint charges a violation of sections 38a-663 to 38a-681, inclusive, and that the complainant would be aggrieved if the violation is proven, he shall proceed as provided in subsection (b) of this section.

(b) If after examination of an insurer, rating organization, advisory organization, or group, association or other organization of insurers which engages in joint underwriting or joint reinsurance, or upon the basis of other information, or upon sufficient complaint as provided in subsection (a) of this section, the Insurance Commissioner has good cause to believe that such insurer, organization, group or association or any rate, rating plan or rating system made or used by any such insurer or rating organization, does not comply with the requirements and standards of said sections applicable to it, he shall, unless he has good cause to believe such noncompliance is wilful, give notice in writing to such insurer, organization, group or association stating therein what manner and to what extent such noncompliance is alleged to exist and specifying therein a reasonable time, not less than ten days thereafter, in which such noncompliance may be corrected. Notices under this section shall be confidential as between said commissioner and the parties unless a hearing is held in accordance with the provisions of subsection (c) of this section.

(c) If the Insurance Commissioner has good cause to believe such noncompliance to be wilful, or if within the period prescribed by said commissioner in the notice required by subsection (b) of this section the insurer, organization, group or association does not make such changes as may be necessary to correct the noncompliance specified by said commissioner or establish to the satisfaction of said commissioner that such specified noncompliance does not exist, then said commissioner may hold a public hearing in connection therewith, provided within a reasonable period of time, which shall be not less than ten days before the date of such hearing, he shall mail a written notice specifying the matters to be considered at such hearings to such insurer, organization, group or association. If no notice has been given as provided in subsection (b) of this section such notice shall state therein in what manner and to what extent noncompliance is alleged to exist. The hearing shall not include any additional subjects not specified in the notices required by said subsection (b).

(d) If after a hearing pursuant to subsection (c) of this section, the Insurance Commissioner finds (1) that any rate, rating plan or rating system violates the provisions of sections 38a-663 to 38a-681, inclusive, applicable to it, he may issue an order to the insurer or rating organization which has been the subject of the hearing specifying in what respects such violation exists and stating when, within a reasonable period of time, the further use of such rate or rating system by such insurer or rating organization in contracts of insurance made thereafter shall be prohibited; (2) that an insurer, rating organization, advisory organization, or a group, association or other organization of insurers which engages in joint underwriting or joint reinsurance, is in violation of the provisions of said sections applicable to it other than the provisions dealing with rates, rating plans or rating systems, he may issue an order to such insurer, organization, group or association which has been the subject of the hearing specifying in what respects such violation exists and requiring compliance within a reasonable time thereafter; (3) that the violation of any of the provisions of said sections applicable to it by any insurer or rating organization which has been the subject of hearing was wilful, he may suspend or revoke, in whole or in part, the certificate of authority of such insurer or the license of such rating organization with respect to the class of insurance which has been the subject matter of the hearing; (4) that any rating organization has wilfully engaged in any fraudulent or dishonest act or practices, he may suspend or revoke, in whole or in part, the license of such organization in addition to any other penalty provided in said sections; (5) in addition to other penalties provided by law the Insurance Commissioner may suspend or revoke, in whole or in part, the license of any rating organization or the certificate of authority of any insurer with respect to the class or classes of insurance specified in such order, which fails to comply within the time limited by such order or any extension thereof which said commissioner may grant, with an order of said commissioner lawfully made by him pursuant to this subsection and effective pursuant to subdivision (7) of this subsection; (6) except as otherwise provided in sections 38a-663 to 38a-681, inclusive, all proceedings in connection with the denial, suspension or revocation of a license or certificate of authority under said sections shall be conducted in accordance with the provisions of § 38a-41 and the Insurance Commissioner shall have all the powers granted to him therein; (7) any findings, determination, rule, ruling or order made by the Insurance Commissioner, in accordance with the provisions of said sections, shall be subject to review by appeal in accordance with the provisions of § 4-183. No such finding, determination, rule, ruling or order shall become effective before the expiration of twenty days after notice and a copy thereof are mailed or delivered to the person affected, and any finding, determination, rule, ruling or order of said commissioner so submitted for review shall not become effective for a further period of fifteen days after the petition for review is filed with the court. The court may stay the effectiveness thereof for a longer period.
