Constitution of the State of Georgia Art. III, § 9, ¶ V

In addition to the appropriations made by the general appropriations Act and amendments thereto, the General Assembly may make additional appropriations by Acts, which shall be known as supplementary appropriation Acts, provided no such supplementary appropriation shall be available unless there is an unappropriated surplus in the state treasury or the revenue necessary to pay such appropriation shall have been provided by a tax laid for such purpose and collected into the general fund of the state treasury. Neither house shall pass a supplementary appropriation bill until the general appropriations Act shall have been finally adopted by both houses and approved by the Governor.
