S.C. Code Ann. § 24-27-300: Contempt of court.

The court may hold a prisoner in contempt of court if it finds that the prisoner has, on three or more prior occasions, while incarcerated, brought in a court of this State a civil action or appeal pertaining to his incarceration or apprehension that was dismissed prior to a hearing on the merits on the grounds that the action or appeal was frivolous, malicious, or meritless. However, if the court finds the prisoner was under imminent danger of great bodily injury, as defined by Section 56-5-2945, at the time of the filing of the present action or appeal, the prisoner shall not be held in contempt. The court may sentence the prisoner to a term of imprisonment not exceeding one year for this contempt to be served consecutively to any terms of imprisonment previously imposed.
