S.C. Code § 14-5-920
Whenever it shall satisfactorily appear to any circuit judge that the public interest requires the holding of a special session of the court of general sessions or common pleas in any county in which he is at the time presiding over the court then in session such circuit judge may order a special session of the court of general sessions or common pleas to be held for such county at such time and for such term and such notice of the holding thereof shall be given as he may by order provide, which order shall be entered upon the records of the clerk of such court. And when such special session is so ordered only the circuit judge ordering the same shall hold the court, unless he be incapacitated to do so because of his illness or the illness of some member of his immediate family or because of any other reason considered sufficient in the opinion of the Chief Justice of the Supreme Court, and in that event the Chief Justice of the Supreme Court shall order some other disengaged circuit judge or special judge to hold such court.
