The several counties and municipalities of this state are hereby authorized to fund any judgment indebtedness of such county or municipality and to issue bonds therefor as provided by the general law governing the issuance of bonds by counties and municipalities, respectively. The issuance of such funding bonds under this section shall be deemed and held by all courts in this state, to all intents and purposes, the incurring of a new indebtedness; and thereafter no question shall ever be raised in any court as to the validity of such indebtedness, except questions of constitutional limitation of indebtedness. Such funding bonds shall not be exchanged or delivered in payment of such judgment indebtedness nor any part thereof. The provisions of this section shall not be deemed to be repugnant to nor inconsistent with section 108.140; but the power and authority hereby conferred shall be deemed to be cumulative thereof.
