Mo. Rev. Stat. § 173.410
Bonds or other forms of indebtedness issued under the provisions of sections 173.350 to 173.450 shall not be deemed to constitute a debt or liability of the state or of any political subdivision thereof or a pledge of the full faith and credit of the state or of any such political subdivision, but shall be payable solely from the funds provided for in sections 173.350 to 173.450. The issuance of bonds or other forms of indebtedness under the provisions of sections 173.350 to 173.450 shall not, directly, indirectly, or contingently, obligate the state or any political subdivision thereof to levy any form of taxation therefor or to make any appropriation for their payment. Nothing in this section shall be construed to authorize the authority to create a debt of the state within the meaning of the constitution or statutes of the state of Missouri, and each bond or other form of indebtedness issued by the authority shall be payable and shall state on its face that it is payable solely from the funds pledged for its payment in accordance with the bond resolution authorizing its issuance. The state shall not be liable in any event for the payment of the principal of or interest on any bonds of the authority or for the performance of any pledge, mortgage, obligation, or agreement of any kind whatsoever which may be undertaken by the authority. No breach of any such pledge, mortgage, obligation, or agreement may impose any pecuniary liability upon the state or any charge upon the general credit or taxing power of the state.
