S.D. Codified Laws § 1-16H-23
To secure the payment of any or all of such revenue bonds, notes, or other instruments, the revenues to be received by the authority from a lease agreement or loan agreement shall be pledged, and, for the purpose of setting forth the covenants and undertakings of the authority in connection with the issuance thereof and the issuance of any additional revenue bonds, notes, or other instruments payable from such revenues, income, or other funds to be derived from projects, the authority may execute and deliver a trust agreement. A remedy for any breach or default of the terms of any such trust agreement by the authority may be by mandamus proceedings in the appropriate circuit court to compel the performance and compliance therewith, but the trust agreement may prescribe by whom or on whose behalf the action may be instituted.
