S.C. Code Ann. § 5-7-100

The governing body of the municipalities or its agents may investigate any department of the municipal government and any office thereof and such governing body shall have the same power which a magistrate has to compel the attendance of witnesses and to require them to give evidence under oath in the same manner as is customary in the courts of this State. In case of contumacy of any person or refusal to obey a subpoena issued to any person, any circuit court of this State or circuit judge thereof within the jurisdiction of which the municipality is located, upon application by the governing body of the municipality or its designated agent, may issue to such person an order requiring him to appear before the governing body of the municipality to produce evidence if so ordered or to give testimony on the matter under investigation. Any failure to obey an order of the court may be punished as a contempt thereof. Subpoenas shall be issued in the name of the municipality and shall be signed by a majority of the governing body. Subpoenas shall be issued to such persons as the governing body may designate.
