The validity of any bonds does not depend on, and is not affected in any way by, any proceedings taken by the city for acquisition, construction, or completion of any properties or projects for which the bonds are issued or incurred or any agreements made in connection with the acquisition, construction, or operation of those properties. The bonds will be incontestable and by their issuance or incurrence and delivery will conclusively establish the due performance of all related conditions precedent. (Ord. 2018-0041 § 2)
