(B) Approval of Bonds. No bonds or other obligations shall be issued or sold by the state, directly or through any state board, agency, or commission, or by any political subdivision of the state, unless prior written approval of the bond commission is obtained.
(C) Contesting State Bonds. Bonds, notes, certificates, or other evidences of indebtedness of the state (hereafter referred to as "bonds") shall not be invalid because of any irregularity or defect in the proceedings or in the issuance and sale thereof and shall be incontestable in the hands of a bona fide purchaser or holder. The issuing agency, after authorizing the issuance of bonds by resolution, shall publish once in the official journal of the state, as provided by law, a notice of intention to issue the bonds. The notice shall include a description of the bonds and the security therefor. Within thirty days after the publication, any person in interest may contest the legality of the resolution, any provision of the bonds to be issued pursuant to it, the provisions securing the bonds, and the validity of all other provisions and proceedings relating to the authorization and issuance of the bonds. If no action or proceeding is instituted within the thirty days, no person may contest the validity of the bonds, the provisions of the resolution pursuant to which the bonds were issued, the security of the bonds, or the validity of any other provisions or proceedings relating to their authorization and issuance, and the bonds shall be presumed conclusively to be legal. Thereafter no court shall have authority to inquire into such matters.
