DEFENSE

New Charges Against Hughes Unsealed: Federal prosecutors unsealed 60 new defense fraud charges against Hughes Aircraft that--if proven in court--could result in fines of up to $50 million. The company and one of its employees are alleged to have falsified tests on electronic components used in military weapons systems. Hughes, which previously faced 40 charges, pleaded not guilty at its arraignment last week and said it would defend itself vigorously.
