(a) Each advisory organization and every insurer subject to this chapter that makes its own rates shall provide within this State reasonable means whereby any person aggrieved by the application of its rating system, including, but not limited to, issues of proper formulation and application of experience modification factors and/or proper classification of employers, may upon that person's written request be heard in person or by the person's authorized representative to review the manner in which such advisory organization's or insurer's rating system, experience rating plan or employer classifications have been applied in connection with the insurance afforded the aggrieved person.
(b) Any party affected by the action of the advisory organization or the insurer may, within 30 days after written notice of that action, make application, in writing, for an appeal to the Commissioner, setting forth the basis for the appeal and the grounds to be relied upon by the applicant.
(c) The Commissioner shall review the application and, if the Commissioner finds that the application is made in good faith and that it sets forth on its face grounds which reasonably justify holding a hearing, the Commissioner shall conduct a hearing held not less than 20 days after written notice to the applicant and to the advisory organization or insurer. The Commissioner, after hearing, shall affirm or reverse the action of the advisory organization or insurer.
