In Washington, Judge Harold Greene today starts his final day of hearings on submissions from the seven regional phone companies, the Federal Communications Commission, the Justice Department and other interested parties on relaxation on the regulatory restrictions on the regionals: Monday was on whether they should be allowed to compete in long-distance service, where the Justice Department is making ambivalent recommendations, but seems to want to forbid international service – which could put the kibosh on Nynex Corp’s plans to collaborate on Cable & Wireless’ transatlantic cable; yesterday was on manufacturing, and today is on information services; Judge Greene is not expected to deliver himself of his decisions until the autumn.
