S.C. Code § 38-73-1030
Any person or organization aggrieved with respect to any filing which is in effect may make written application to the director or his designee for a hearing thereon, except that the insurer or rating organization that made the filing may not proceed under this section. The application shall specify the grounds to be relied upon by the applicant. If, within thirty days after receipt of the application, the director or his designee finds that the application is made in good faith, that the applicant would be so aggrieved if his grounds are established, and that the grounds otherwise justify holding a hearing, he shall hold a hearing upon not less than thirty days' written notice to the applicant and to every insurer and rating organization which made the filing. If, after the hearing, the director or his designee finds that the filing does not meet the requirements of this chapter, he shall issue an order specifying in what respects he finds that the filing fails to meet the requirements of this chapter and stating when, within a reasonable period thereafter, the filing is considered no longer effective. Copies of the order must be sent to the applicant and to every insurer and rating organization which made the filing. The order does not affect any contract or policy made or issued prior to the expiration of the period set forth in the order.
