S.C. Code Ann. § 38-57-290: Action for recovery of fine paid under protest.

Any person paying a fine levied by the director or his designee, under protest, may at any time within thirty days after payment, but not afterwards, bring an action against the director or his designee for the recovery thereof in the court of common pleas of the county in which the fine was payable. If it is determined in that action that the fine was wrongfully or illegally levied and collected, for any reason going to the merits, the court before whom the case is tried shall certify of record that the fine was wrongfully collected and should be refunded and thereupon the Comptroller General shall issue his warrant for the refunding of the fine so paid.
