S.C. Code Ann. § 12-60-1330
Before a person may seek a determination by an administrative law judge under Section 12-60-1320, he shall exhaust his prehearing remedy. If a person requests a contested case hearing before the Administrative Law Judge Division without exhausting his prehearing remedy because he failed to file a protest, the administrative law judge shall dismiss the action without prejudice. If the person failed to provide the department with the facts, law, and other authority supporting his position, he shall provide the department with the facts, law, and other authority he failed to present to the department earlier. The administrative law judge shall then remand the case to the department for reconsideration in light of the new facts or issues unless the department elects to forego the remand. Upon remand the department has thirty days, or a longer period ordered by the administrative law judge, to consider the new facts and issues and amend its department determination. The department shall issue its amended department determination in the same manner as the original. The person has thirty days after the date the department's amended determination was sent by first class mail or delivered to the person to again request a contested case hearing. Requests for a hearing before the Administrative Law Judge Division must be made in accordance with its rules. If the department fails to issue its amended department determination within thirty days of the date of the remand, or a longer period ordered by the administrative law judge, the person can again request a contested case hearing. At the new hearing the facts, law, and other authority presented at the original hearing have been presented in a timely manner for purposes of exhausting the person's prehearing remedy. The statute of limitations remains suspended by Section 12-54-85(G) during this process.
