Despite objections from Gibson Dunn & Crutcher, a federal judge has ordered the firm to turn over to the court for in camera review notes of interviews conducted as part of an internal investigation for a former client that is now being sued for defamation.

Gibson Dunn, which is not a party to the defamation suit, argued that its witness interview notes were the firm’s internal work product and thus protected from discovery. But Southern District Judge Paul Gardephe (See Profile) said the firm doesn’t have a privacy interest in the material.
