Sec. 2. PROCEEDINGS VALIDATED. The governmental acts and proceedings of a municipality relating to a bond election that was held before December 1, 1991, and at which the ballot proposition was approved by more than 60 percent of the voters voting on the proposition are validated as of the dates they occurred. The validation includes the preparation and wording of the ballot proposition, any action taken by the municipality in calling and holding the bond election, and any other action taken by the municipality before the effective date of this article in connection with the issuance of any bonds approved in the bond election. The acts and proceedings may not be held invalid because they were not performed in accordance with law. A municipality may take any further action or conduct any further proceeding necessary to complete the issuance of the bonds approved at the bond election, and, when issued, the bonds are valid and binding obligations of the municipality in accordance with the terms of the bonds.
