A federal has board ordered a Postal Service contract with Texas computer billionaire H. Ross Perot voided because the way in which the contract was awarded violated proper procedures. The contract had been suspended on July 8 after a preliminary ruling which the Postal Service is challenging in the U.S. Court of Appeals. The board concluded Friday that the Postal Service violated federal rules by failing to provide any advance notice of the contract and awarding the contract to Perot without seeking competitive bids.
