S.C. Code Ann. § 22-3-540: Exclusive and concurrent jurisdiction.

Magistrates shall have exclusive jurisdiction of all criminal cases in which the punishment does not exceed a fine of one hundred dollars or imprisonment for thirty days, except cases in which an offense within the jurisdiction of a magistrate is included in the charge of an offense beyond his jurisdiction or when it is permissible to join a charge of an offense within his jurisdiction with one or more of which the magistrate has no jurisdiction. Magistrates shall have concurrent but not exclusive jurisdiction in the excepted cases. The provisions of this section shall not be construed so as to limit the jurisdiction of any magistrate whose jurisdiction has been extended beyond that stated above.
