Michigan Compiled Laws, Chapter 12. State Treasurer § 12.274

Sec. 4. (1) The board of the authority shall authorize a bond issue by resolution. The authority may issue bonds, including refunding bonds, without obtaining the consent of any department, division, commission, board, bureau, or agency of this state and without any proceedings or conditions other than those specifically required by this act. Every bond issue is a special revenue obligation payable from and secured by a pledge of revenues or funds available for that purpose under the Michigan employment security act, 1936 (Ex Sess) PA 1, MCL 421.1 to 421.75, and other assets, including without limitation the proceeds of the bonds deposited in a reserve fund for the benefit of the owners of the bonds, earnings on funds from bonds issued under this act, and other available funds. The bonds are payable upon the terms and conditions specified by the authority in the resolution under which the authority issues the bonds or in a related trust agreement or trust indenture.

(2) The authority may issue bonds to refund any bonds by issuing new bonds if it considers the refunding expedient, whether or not the bonds to be refunded have matured, and may issue bonds partly to refund bonds then outstanding and partly for restructuring or any of the authority's other authorized purposes.
