Consistent with its long-standing support for preserving attorney-client privilege, the BBA filed an amicus brief in Hanover Ins. Company v. Rapo & Jepsen Ins. Services, Inc. and Arbella Mutual Ins. Company. This interlocutory appeal from the entry of a discovery order in an automobile dispute between insurers presented issues regarding attorney-client privilege and work product doctrine in the context of a joint defense agreement: whether Massachusetts law recognizes a joint defense privilege and whether an oral joint defense agreement is enforceable. The brief supported the appellants’ position that Massachusetts recognizes the common interest doctrine, sometimes known as the joint defense privilege.
