In a suit between a bankruptcy trust established to resolve a defunct corporation’s asbestos-related personal injury liabilities and the corporation’s excess liability insurer that had denied coverage to the trust in connection with the asbestos claims, a court resolved various attorney client privilege and work product protection issues. The insurer had sought various documents related to the handling of the underlying asbestos claims by the trust, among others. Many of these documents included communications between counsel and the corporation or between counsel and the bankruptcy creditors’ committee. No privilege existed over documents addressing the handling of the underlying asbestos claims because (1) a common interest exists between the trust and the insurer related to the asbestos claims, and (2) the trust had a duty to cooperate with the insurer based on the primary policy. In contrast, the court held the privilege did exist for a number of documents related to the reinsurance procured by the insurer. Whereas the insurer’s discovery requests were related to the handling of the asbestos claims, the trust’s requests were for the purpose of learning the insurer’s “admissions regarding the matter in dispute.” The court also found a common interest existed between the insurer and its reinsurer regarding the trust’s claims, such that any communications with counsel that may have been shared by the insurer with its reinsurer would not be considered a waiver of privilege.
