S.C. Code § 7-5-250
From the decision of the court of common pleas or any judge thereof the applicant may further appeal to the Supreme Court by filing a written notice of his intention to appeal therefrom in the office of the clerk of court of common pleas within ten days after written notice to him of the filing of such decision and within such time serving a copy of such notice on any member of the county board of voter registration and elections. Thereupon, the clerk of the court of common pleas shall certify all the papers in the case to the clerk of the Supreme Court within ten days after the filing of such notice of intention to appeal. The clerk of the Supreme Court shall place the case on a special docket, and it shall come up for hearing upon the call thereof under such rules as the Supreme Court may make. If such appeal be filed with the clerk of the Supreme Court at a time that a session thereof will not be held between the date of filing and election at which the applicant will be entitled to vote if registered, the Chief Justice or, if he is unable to act or disqualified, the senior associate justice shall call an extra term of the court to hear and determine the case.
