Del. Code tit. 2 § 1417
The expenditures of the Authority from the Transportation Trust Fund, including expenditures required to be made by resolutions or trust agreements made or to be made by the Authority, shall be approved annually by the General Assembly. The obligations under any such resolution or trust agreement shall be met solely from motor fuel taxes, motor vehicle document fees, motor vehicle registration fees, motor carrier road use taxes and registration fees, the moneys transferred or disbursed to the Transportation Trust Fund under § 307 of Title 21, receipts and revenues derived from the Delaware Turnpike and any other receipts and revenues of the Authority pledged and assigned to the holders of bonds of the Authority. The budget for capital and operating expenditures of the Authority payable from the Transportation Trust Fund shall be presented annually by the Authority to the General Assembly. If the General Assembly does not approve the operating budget of the Authority before July 1 for the year such budget is submitted, the operating budget, as submitted to the General Assembly, shall be deemed adopted by the Authority until such time as the budget is approved by the General Assembly, provided that the operating expenditures of the Authority shall not exceed similar expenditures of the Authority for the year before the budget year by more than a factor equal to the Consumer Price Index as defined in § 1320(f) of this title. Any obligations incurred by the Authority under an operating budget deemed adopted by the Authority shall be binding on the Authority. Failure by the General Assembly to approve the capital or operating budget of the Authority shall not affect or impair the obligation of the Authority to meet its obligations to holders of outstanding bonds. The provisions of Chapter 84 of Title 29, including the establishment of priorities for spending state funds, shall apply to available money and bonding capacity in the Transportation Trust Fund for highway projects. The Authority's annual budget as prepared and approved shall reflect that a significant objective of this chapter is to achieve adequate funding and predictable implementation of the Department of Transportation's Capital Transportation Program and other needs of the transportation system.
