A. In case any of the representatives of the housing authority whose signatures appear on any bonds or coupons cease to be commissioners, officers, or agents of the issuing authority before the delivery of such bonds, the signatures shall, nevertheless, be valid and sufficient for all purposes, the same as if the representatives had remained in office until delivery. Any law to the contrary notwithstanding, bonds issued pursuant to this Chapter are fully negotiable.
B. No suit, action, or proceeding involving the validity or enforceability of any bond of a housing authority may be commenced after delivery of the bond. In any suit, action, or proceeding involving the validity or enforceability of any bond of a housing authority or the security therefor, any such bond reciting in substance that it has been issued by the housing authority to aid in financing a development or activity furthering the purposes of this Chapter is conclusively deemed to have been issued in accordance with this Chapter, and any development financed thereby and with respect to which such recitation made shall be conclusively deemed to have been planned, located, and constructed in accordance with this Chapter.
