S.C. Code § 44-23-450
A finding of unfitness to stand trial under Section 44-23-430 may be reexamined by the court upon its own motion, or that of the prosecuting attorney, the person found unfit to stand trial, his legal guardian, or his counsel. Upon receipt of the petition, the court shall order an examination by two designated examiners whose report shall be submitted to the court and shall include underlying facts and conclusions. The court shall notify the individual, his legal guardian, and his counsel of a hearing at least ten days prior to such hearing. The court shall conduct the proceedings in accordance with Section 44-23-430, except that any petition that is filed within six months after the initial finding of unfitness or within six months after the filing of a previous petition under this section shall be dismissed by the court without a hearing.
