S.C. Code Ann. § 8-17-340

The State Human Resources Director shall forward to the committee for a hearing all appeals which meet jurisdictional requirements and relate to the following adverse employment actions: terminations, salary decreases based on performance, demotions, suspensions for more than ten days, and reductions in force when the State Human Resources Director determines there is a material issue of fact regarding inconsistent or improper application of the agency's reduction in force plan or policy. The committee shall consist of at least eighteen and not more than twenty-four members who must be appointed by the State Budget and Control Board to serve for terms of three years and until their successors are appointed and qualify.
