No bonds or other obligations of and no indebtedness incurred by any authority shall constitute an indebtedness or obligation of the State of Georgia or of any county, municipal corporation, or political subdivision thereof, nor shall any act of any authority in any manner constitute or result in the creation of an indebtedness of this state or of any such county, municipal corporation, or political subdivision. However, provisions of this Code section shall not preclude counties, municipal corporations, or other political subdivisions from choosing to guarantee the bonds, indebtedness, or other obligations of a regional solid waste authority as part of its demonstration of adequate financial responsibility pursuant to this part. All such bonds and obligations shall be payable solely from the revenues therein pledged to such payment, including pledged rentals, sales proceeds, insurance proceeds, and condemnation awards; and no holder or holders of any such bonds or obligation shall ever have the right to compel any exercise of the taxing power of this state or of any county, municipal corporation, or political subdivision thereof or to enforce the payment thereof against any property of the state or of any such county, municipal corporation, or political subdivision.
