S.D. Codified Laws § 46A-1-42

Any bonds issued pursuant to this chapter are obligations of the district payable only in accordance with the terms of the bonds and are not obligations general, special, or otherwise, of the State of South Dakota. Such bonds do not constitute a debt, legal or moral, of the State of South Dakota, and are not enforceable against the state. Payment of the bonds is not enforceable out of any funds of the district other than the income and revenues pledged and assigned to, or in trust for the benefit of, the holder or holders of the bonds.
