S.C. Code Ann. § 11-11-410
(E) Notwithstanding the provisions of subsection (A) of this section, the General Assembly may declare a financial emergency and suspend the spending limitation for any one fiscal year for a specific amount by a special vote as provided in this subsection by enactment of legislation which relates only to that matter. The authorized state appropriations for the fiscal year following the suspension must be determined as if the suspension had not occurred and, for purposes of determining subsequent limits, must be presumed to have been the maximum limit which could have been authorized if such limitation had not been suspended.
The special vote referred to in this subsection means an affirmative vote in each branch of the General Assembly by two-thirds of the members present and voting but not less than three-fifths of the total membership in each branch.
