(a) No officer, department, board, commission, institution or other agency of the state shall, after the close of any fiscal year, incur, or vote or order or approve the incurring of, any obligation or expenditure under any appropriation made by the General Assembly for any fiscal year that had expired at the time the obligation for such expenditure was incurred. The Comptroller is authorized to draw warrants or process interdepartmental transactions against the available appropriations made for the current fiscal year for the payment of expenditures incurred during the prior fiscal year for which appropriations were made or in fulfillment of contracts properly made during such prior year, and the Treasurer is authorized to pay such warrants or record such interdepartmental transactions. The balances of certain appropriations which otherwise would lapse at the close of any fiscal year and for which no appropriation is made in the following year shall be extended into the succeeding fiscal year to permit liquidation of obligations of the prior fiscal year.

(b) Except as provided in this section, all unexpended balances of appropriations made by the General Assembly in the state budget act shall lapse at the end of the period for which they have been made and shall revert to the unappropriated surplus of the fund from which such appropriation or appropriations were made, except that any appropriation for the improvement of or maintenance work by contract on public roads, for the purchase of land or the erection of buildings or new construction or for specific projects for capital improvements and repairs, provided in the case of such specific projects allotments shall have been made by the Governor for design and construction, shall continue to be available until the attainment of the object or the completion of the work for which such appropriation was made, but in no case for more than six years unless renewed by act of the General Assembly.

(c) All unexpended balances of special appropriations made by the General Assembly for special programs, projects or studies shall lapse at the end of the period for which they have been made, except that if satisfied that the work of any such program, project or study is not completed and will continue during the following fiscal year, the Secretary of the Office of Policy and Management shall order any unexpended balance remaining in the special appropriation to be continued to the ensuing fiscal year.

(d) Any appropriation made by the General Assembly for no specific period, or any unexpended balance thereof, shall lapse on June thirtieth in the fourth year after such appropriation was made, provided when the purpose for which any such appropriation was made has been accomplished or there is no further need for funds thereunder, the unexpended balance thereof, upon the written consent of the head of the department, board, commission, institution or other agency to which such appropriation was made, shall lapse and shall revert to the unappropriated surplus of the fund from which such appropriation was made.

Such appropriations shall not lapse until the end of the fiscal year succeeding the fiscal year of the appropriation, provided an obligation to spend such funds has been incurred in the next preceding fiscal year, except that for the purposes of library or educational equipment or materials, such funds shall not exceed twenty-five per cent of the amount of the appropriation for such purposes.
