Ala. Code § 16-6K-13: Interest of Bondholders Protected; Enforceability.

While any of the bonds issued by the authority remain outstanding, the powers, duties, or existence of the authority or of any of its officers shall not be diminished or impaired in any manner that will affect adversely the interest and rights of the holders of such bonds. The provisions of this chapter shall be for the benefit of the state, the authority, and the holders of any bonds, and, upon the issuance of the bonds as herein provided, the provisions shall constitute a contract with the holders of the bonds. The provisions of any bond resolution, indenture, or trust agreement shall be a contract with every holder of the bonds, and the duties of the authority under any bond resolution, indenture, or trust agreement shall be enforceable by any bondholder by mandamus or other appropriate suit, action, or proceeding at law or in equity.
