No appropriation, contract, or other action shall be held invalid or set aside by reason of any error, including without limitation any irregularity, informality, neglect, or omission, in carrying out procedures specified in Sections 16.128-1 through 16.128-12, unless a court finds that the party challenging the action suffered substantial injury from the error and that a different result would have been probable had the error not occurred.
