An attorney employed by any executive agency of the State may, with the permission of his agency head, represent without fees indigent clients referred by a pro bono program organized, sponsored, or endorsed by the South Carolina Bar. The pro bono service must be at no cost to the State, and may not conflict with the attorney's official duties or the interests of the State. The attorney shall use compensatory or annual leave for pro bono services performed during normal working hours. Practice by attorneys employed by the General Assembly or the Judicial Department shall be governed by such policies and rules as may be adopted by their respective employer.
