Section 159.04 - Neither credit nor taxing power pledged(1) Revenue bonds issued under the provisions of this part shall not be deemed to constitute a debt of the unit issuing the same or a pledge of the faith and credit of such unit, except as provided in s. 159.16, but such bonds shall be payable from the funds hereinafter provided therefor from revenues and any other special funds pledged for the payment of such bonds as provided herein. All such bonds shall contain a statement on their face to the effect that such unit is not obligated to pay the same or the interest thereon except from revenues and other special funds provided for in this part, and that the faith and credit of the unit are not pledged to the payment of the principal or interest of such bonds.(2) The issuance of revenue bonds under the provisions of this part shall not directly or indirectly or contingently obligate the unit to levy or to pledge any form of ad valorem taxation whatever therefor. No holder of any such revenue bonds shall ever have the right to compel any exercise of the ad valorem taxing power on the part of such unit to pay any such bonds or the interest thereon or to enforce payment of such bonds or the interest thereon against any property of the unit, nor shall such bonds constitute a charge, lien or encumbrance, legal or equitable, upon any property of such unit, except the revenues and other special funds pledged for the payment of such revenue bonds.s. 4, ch. 28045, 1953; s. 4, ch. 67-550.
