Ga. Const. art. III, § 9, para. 4

(a) Each general appropriations Act, now of force or hereafter adopted with such amendments as are adopted from time to time, shall continue in force and effect for the next fiscal year after adoption and it shall then expire, except for the mandatory appropriations required by this Constitution and those required to meet contractual obligations authorized by this Constitution and the continued appropriation of federal grants.

(b) The General Assembly shall not appropriate funds for any given fiscal year which, in aggregate, exceed a sum equal to the amount of unappropriated surplus expected to have accrued in the state treasury at the beginning of the fiscal year together with an amount not greater than the total treasury receipts from existing revenue sources anticipated to be collected in the fiscal year, less refunds, as estimated in the budget report and amendments thereto. Supplementary appropriations, if any, shall be made in the manner provided in Paragraph V of this section of the Constitution; but in no event shall a supplementary appropriations Act continue in force and effect beyond the expiration of the general appropriations Act in effect when such supplementary appropriations Act was adopted and approved.

(c) All appropriated state funds, except for the mandatory appropriations required by this Constitution, remaining unexpended and not contractually obligated at the expiration of such general appropriations Act shall lapse.

(d) Funds appropriated to or received by the State Housing Trust Fund for the Homeless shall not be subject to the provisions of Article III, Section IX, Paragraph IV(c), relative to the lapsing of funds, and may be expended for programs of purely public charity for the homeless, including programs involving the participation of churches and religious institutions, notwithstanding the provisions of Article I, Section II, Paragraph VII.
