Diebold Election Systems told the State Board of Elections it would be impossible to meet a Thursday deadline to account for all software used by the company for machines certified to be sold in all 100 counties.
The decision means that only one vendor currently is cleared to sell equipment, raising more questions about whether counties will have enough time to buy machines that meet the state's technical and security standards.
"We've said that we can't comply with the black letter of the law," said Chuck Owen, a Diebold attorney in Texas who alerted the board of its decision late Wednesday. "And we don't believe any vendor can comply with the black letter of the law."
