N.D. Cent. Code § 61-08-42
Revenue bonds issued under this chapter may not be payable from nor charged upon any funds other than the revenue pledged to the payment of the bonds, nor is the district issuing the bonds subject to any pecuniary liability on the bonds. A holder of the bonds does not have the right to compel the levy of special assessments to pay the bonds or the interest, or to enforce payment of the bonds against any property of the district other than property pledged as security for the bonds. Each revenue bond issued under this chapter must recite in substance that the bond, including interest on the bond, is payable solely from the revenue pledged to the payment of the bond, and that the bond does not constitute a debt of the district within the meaning of any constitutional or statutory limitation.
