Delaware constitution
Article VIII
Section 10

(b) Prior to the beginning of each fiscal year of the State, the General Assembly shall appropriate revenues of the State to pay interest on its debt to which it has pledged its faith and credit and which interest is payable in the year for which such appropriation is made and to pay the principal of such debt, payable in such year, whether at maturity or otherwise. To the extent that insufficient revenues of the State are available to pay principal of and interest on such debt when due and payable, the first public moneys of the State thereafter received shall be set aside and applied to the payment of the principal of and interest on such debt. To make up for such insufficient revenues, the General Assembly may increase the rate of taxes and fees without regard to the limitations of subsection (a) hereof after the failure to pay when due the principal of and interest on such debt.
