N.D. Cent. Code § 40-57-15
Revenue bonds issued under this chapter shall not be payable from nor charged upon any funds other than the revenue pledged to the payment thereof, nor shall the municipality issuing the same be subject to any liability thereon. No holder or holders of any such bonds shall ever have the right to compel any exercise of the taxing power of the municipality to pay any such bonds or the interest thereon, nor to enforce payment thereon against any property of the municipality except those projects, or portions thereof, mortgaged or otherwise encumbered under the provisions and for the purpose of this chapter. Such bonds shall not constitute a charge, lien, nor encumbrance, legal or equitable, upon any property of the municipality, except those projects, or portions thereof, mortgaged or otherwise encumbered under the provisions and for the purposes of this chapter.
Each bond under this chapter shall recite in substance that the bond, including interest thereon, is payable solely from the revenue pledged to the payment thereof, except that such bond may be secured by a mortgage or other encumbrance on the project, or portion thereof, as authorized in this chapter, and that the bond does not constitute a debt of the municipality within the meaning of any constitutional or statutory limitation.
