Okla. Stat. tit. 62, § 62-828: Issuance of bonds by participating entities – Examination

by Attorney General.

Once a Regional District has been established by the Governor,

the governing bodies of each of the Participating Entities

comprising such district shall take all actions required by law for

the issuance of the type of bonds described in the Final Project

Plan. A transcript of proceedings for each of the Participating

Entities shall thereafter be prepared and submitted to the Attorney

General of Oklahoma for examination. Such bonds, having been

examined and certified as legal obligations by the Attorney General

in accordance with such requirements as the Attorney General may

make, shall be incontestable in any court of the State of Oklahoma

unless suit thereon shall be brought in a court having jurisdiction

thereof within thirty (30) days from the date of such approval.

Bonds so approved by the Attorney General shall be prima facie valid

and binding obligations according to their terms. The only

objection which may be offered thereto in any suit instituted after

such thirty-day period shall have expired shall be a violation of

provisions of either the United States Constitution or the Oklahoma

Constitution.
