Ind. Code § 5-1.2-7-12
Nothing in this chapter may be construed as a restriction or limitation upon any powers which the authority might otherwise have under any other law of this state, and this chapter is cumulative to these powers. This chapter shall be construed to provide a complete, additional, and alternative method for the doing of the things authorized, and shall be construed as supplemental to powers conferred by any other laws. The adoption by the authority of bylaws and rules, and the issuance of bonds by the authority under this chapter need not comply with the requirements of any other state laws applicable to the adoption of bylaws and rules and the issuance of bonds, notes, and other obligations. No proceedings, notice, or approval is required for the issuance of any bonds or any instrument or the security for the bonds or instruments, or for the proper conduct of the authority's business, affairs, or operations, except as provided in this chapter.
