S.C. Code Ann. § 6-27-20
There is created the Local Government Fund administered by the State Treasurer. This fund is part of the general fund of the State. It is the intent of the General Assembly that this fund not be subject to mid-year cuts. However, if mid-year cuts are mandated by the State Budget and Control Board to avoid a year-end deficit, this fund is not subject to such cuts, except by a majority vote of the entire State Budget and Control Board which is separate and apart from any other reduction. These cuts are permitted only to the extent that counties and municipalities do not receive less funding than received in the immediate preceding fiscal year. The Local Government Fund must be financed as provided in this chapter.
