B&W; Still Can’t Depose CBS

Brown & Williamson Corp. lost its latest effort to depose staffers at Westinghouse Electric Corp.’s CBS network in the cigarette maker’s case against a former employee.

A New York state judge ruled in February that Brown & Williamson failed to show that subpoenas for CBS testimony were crucial to its case against Jeffrey Wigand, B&W;’s former head of research.

B&W; appealed. The appellate division on Thursday denied the Louisville, Ky.-based company’s request to oppose the ruling before the state’s Court of Appeals.

B&W;, a unit of Britain’s B.A.T. Industries, is suing Wigand for theft and breach of confidentiality agreements.
