Bonds of the authority shall be confirmed and validated in accordance with the procedure
of O.C.G.A. tit. 36, ch. 82, art. 3 (O.C.G.A. § 36-82-60 et seq.), the Revenue Bond
Law. The petition for validation shall also make party defendant to such action any
authority, subdivision, instrumentality, agency or municipal corporation of the State
of Georgia, or any other lessee which has contracted with the county building authority
for the use of any building, structure, or facilities for which bonds have been issued
and sought to be validated, and such authority, subdivision, instrumentality, agency,
or lessee shall be required to show cause, if any, why such contract or contracts
and the terms and conditions thereof should not be inquired into by the court and
the validity of the terms thereof determined, and the contract adjudicated as security
for the payment of any such bonds of the authority. The bonds when validated and the
judgment of validation shall be final and conclusive with respect to such bonds and
against the authority issuing the same, and any authority, subdivision, instrumentality,
agency, municipal corporation, or other lessee contracting with the county building
authority.
