(a) Shall not be payable from nor charged upon any funds other than the revenue pledged to the payment thereof, except as provided in this section, nor shall the city be subject to any liability thereon. No holder or holders of such bonds shall ever have the right to compel any exercise of the taxing power of the city to pay any such bonds or the interest thereon, nor to enforce payment thereof against any property of the city except those projects or portions thereof, mortgaged or otherwise encumbered under the provisions and for the purposes of ORS 280.410 to 280.485.
(b) Shall not constitute a charge, lien or encumbrance, legal or equitable, upon any property of the city, except those eligible projects, or portions thereof, mortgaged or otherwise encumbered, under the provisions and for the purposes of ORS 280.410 to 280.485.
(2) Each bond issued under ORS 280.410 to 280.485 shall recite in substance that the bond, including interest thereon, is payable solely from the revenue pledged to the payment thereof, and that no such bond shall constitute a debt of the city or a lending of the credit of the city within the meaning of any constitutional or statutory limitation. However, nothing in ORS 280.410 to 280.485 is intended to impair the rights of holders of bonds to enforce covenants made for the security thereof as provided in ORS 280.480. [1977 c.772 §14]
