Bonds issued under this chapter shall have all the qualities of negotiable paper, shall be incontestable in the hands of bona fide purchasers or holders for value and are not invalid for any irregularity or defect in the proceedings for their issuance and sale. This chapter is intended to afford an alternative method for the issuance of bonds by local political subdivisions and may not be so construed as to deprive any local political subdivision of the right to issue its bonds under authority of any other statute, but nevertheless this chapter shall constitute full authority for the issue and sale of bonds by local political subdivisions. The provisions of Section 11-1-1 are not applicable to bonds issued under this chapter. Any local political subdivision subject to the provisions of any budget law shall in its annual budget make proper provision for the payment of principal and interest currently falling due on bonds issued hereunder, but no provision need be made in any such budget prior to the issuance of the bonds for the issuance thereof or for the expenditure of the proceeds thereof. No ordinance, resolution or proceeding in respect to the issuance of bonds hereunder shall be necessary except as herein specifically required, nor shall the publication of any resolution, proceeding or notice relating to the issuance of the bonds be necessary except as herein required. Any publication made hereunder shall be made by providing notice for the local political subdivision, as a class A notice under Section 63G-30-102. No resolution adopted or proceeding taken hereunder shall be subject to referendum petition or to an election other than as herein required. All proceedings adopted hereunder may be adopted on a single reading at any legally convened meeting of the governing body.
