Ala. Const. art. XI, § 213.23

The state is authorized to become indebted for building construction and improvement purposes at the Alabama State Hospitals and at the Partlow State School for Mental Deficients, and in evidence of the indebtedness so incurred to sell and issue, in addition to all other bonds of the state, interest bearing general obligation bonds of the state not exceeding four million dollars in principal amount. The bonds shall be general obligations of the state of Alabama and the full faith and credit and taxing power of the state are hereby pledged to the prompt and faithful payment of the principal of the bonds and the interest thereon. The proceeds from the sale of such bonds are hereby appropriated and shall be used exclusively for the acquisition of building sites; for the construction, reconstruction, alteration, and improvement of building facilities, including renewal and replacement of structural parts; and for the procurement of equipment for such buildings at the Alabama State Hospitals and at the Partlow State School for Mental Deficients; provided that the expenses incurred in connection with the sale and issuance of the bonds may also be paid from such proceeds.

All bonds issued hereunder and the interest thereon shall be payable from any funds in the state treasury not otherwise appropriated. The bonds shall be payable in substantially equal installments of principal and interest beginning in the next fiscal year after their date. They shall bear interest at a rate not to exceed three percent, and they shall contain a provision for their call for payment at such a time or times prior to maturity, and at such a premium, if any, as may be prescribed in the notice of sale. All bonds issued hereunder shall be sold to the best bidder at a duly advertised public sale, upon sealed bids or at auction, and shall not be sold for less than par and accrued interest; provided, however, that bidders may be invited to name the rate or rates of interest which the bonds are to bear. The right to reject any or all bids shall be reserved. Bonds issued hereunder shall mature within twenty years from the date of issuance.

The legislature shall adopt appropriate enabling legislation to carry out the intent and purpose of this amendment to the Constitution.
