A dispute arose between the city of Warren, Michigan and several insurance companies regarding their duties to defend and indemnify with respect to a state court class action suit against the city. The city sought to compel discovery of underwriting manuals, documents reflecting the company’s interpretation of key policy terms, and documents reflecting discussions with reinsurers and the setting of reserves from United States Fire Insurance Company as well as a series of other insurers who had provided coverage at various points between the 1960s and 2001. The district court granted the city’s motion to compel as to the claims manuals, underwriting manuals, and related documents, and denied all other requests. Specifically, the court found that (1) the other claims-related material was covered by attorney-client privilege or the work-product doctrine; (2) materials evidencing interpretation of policy terms were not relevant; and (3) while reinsurance policies themselves are discoverable, all other documents relating to reinsurance are irrelevant and not discoverable. United States Fire Insurance Co. v. The City of Warren, No. 10-13128 (E.D. Mich. Apr. 26, 2012).
