Constitution of the State of Delaware, Art. VIII, § 10. Limitation on increase of rate of taxes and license fees;  exception to meet obligation under faith and credit pledge;  allocation of public moneys to meet such obligation if revenues are not sufficient to meet such pledge

(a) The effective rate of any tax levied or license fee imposed by this State may not be increased except by an Act an act   1 of the General Assembly adopted with the concurrence of three-fifths of all members of each House.

(b) Before the beginning of each fiscal year of this State, the General Assembly shall appropriate revenues of this 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 this State are available to pay principal of and interest on such debt when due and payable, the first public moneys of this 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) of this Section after the failure to pay when due the principal of and interest on such debt.
