S.C. Code Ann. § 58-17-4170
Whenever any of the railroad corporations of this State have repeatedly and wilfully violated any of the provisions of this chapter, and have been found guilty or judgment had against them within this State of such violation more than once or penalties have been recovered in penal actions for such violations more than once, the Commission may, if it thinks it consistent with the public interest, instruct the Attorney General to proceed against such corporation, in any court of competent jurisdiction, by an information in the nature of a quo warranto, alleging such convictions or recoveries as cause of forfeiture of its charter of incorporation and upon proof of such facts there shall be judgment of ouster and final execution as in other cases of proceedings by quo warranto.
