In 2017, Steptoe & Johnson won a major victory in U.S. District Court on behalf of client St. Paul Fire and Marine Insurance Co., now a subsidiary of Travelers, in a major asbestos-related insurance coverage dispute with Walter E. Campbell Co. (WECCO), an insulation firm based in Maryland.

At issue was the application of In Re Wallace & Gale, 385 F.3d 820, and the “completed operations hazard clause” found in various insurance policies that limits the exposure of insurance companies against claims by policyholders such as WECCO.
