O.C.G.A. § 12-3-268 (2019)

While any of the bonds issued by the authority remain outstanding, the powers, duties, or existence of the authority, or of its officers, employees, or agents, or of any department, board, commission, or agency of the state, shall not be diminished or impaired in any manner that will affect adversely the interests and rights of the holders of such bonds. No other entity, department, agency, or authority will be created which will compete with the authority to such an extent as to affect adversely the interests and rights of the holders of such bonds, nor will the state itself so compete with the authority. This part shall be for the benefit of the state, the authority, and the holders of any such bonds and, upon the issuance of bonds under the provisions of this part, shall constitute a contract with the holders of such bonds.
