S.C. Code § 14-3-340
Whenever in the course of any action or proceeding in the Supreme Court arising in the exercise of the original jurisdiction conferred upon the court by the Constitution and laws of the State an issue of fact shall arise upon the pleadings or when an issue of fact shall arise upon a traverse to return in mandamus, prohibition or certiorari, or whenever the determination of any question of fact shall be necessary to the exercise of the jurisdiction conferred upon the Supreme Court, the court may frame an issue therein and certify the same to the circuit court for the county wherein the cause shall have originated or in case of original jurisdiction to the circuit court of the county in which the cause of action shall have arisen. The Supreme Court shall also have the same powers as are now possessed by the circuit courts of the State for the appointment of referees to take testimony and report thereon, under such instructions as may be prescribed by the court, in any cases arising in the Supreme Court wherein issues of fact shall arise.
