Diebold Election Systems Inc. , one of the country's largest manufacturers of voting machines, is scheduled to argue in court today that the Office of the Secretary of State wrongly picked another company to supply thousands of voting machines for the disabled.

Diebold says it will ask a judge to overturn the selection of AutoMARK , a Diebold business competitor, because the office of Secretary of State William F. Galvin failed to choose the best machine.

The contract is valued at about Weisberg said Diehold was so stunned it did not get the contract that it now believes "it's worth the time and money" of going to court to challenge the contract's award, even though the company at this stage has no hard evidence of unfair treatment.
