Okla. Stat. tit. 74, § 74-2258: Validity of bonds - Signatures

Bonds bearing the signatures of Commission officers on the date

of the signing thereof shall be valid and binding obligations,

notwithstanding that before the delivery of the bonds, any or all

the persons whose signatures appear thereon shall have ceased to be

officers of the Commission. The validity of the bonds shall not be

dependent upon nor affected by the validity or regularity of any

proceedings relating to the construction, reconstruction,

improvement, betterment or extension of the properties for which the

bonds are issued. The resolution authorizing the bonds may provide

that the bonds shall contain a recital that they are issued pursuant

to this act, which recital shall be conclusive evidence of their

validity and of the regularity of their issuance.
