Jennings has argued that a review of the software and hardware used in the iVotronic machines will let her prove that a machine malfunction caused the large undervote, allowing her to seek a new election against Buchanan. Mark Herron, a lawyer for Jennings, said voters had a right to review the voting machine codes, which ES&S considers a trade secret, to ensure that the election was properly conducted.
