The Seventh Circuit Rejects Navigators Insurance Company’s Attempt to Escape Additional Insured Coverage For a Gas Explosion

March 24, 2026 — Kyle A. Rudolph & Anna M. Perry - Saxe Doernberger & Vita, P.C.
In a recent Seventh Circuit decision, Atlanta Gas Light Company v. Navigators Insurance Company, the court addressed a theme that policyholders are often confronted with by insurers[1] – insurers disputing additional insured coverage where the named insured is not named in the underlying action. The court aptly rejected this position since it was undisputed that the bodily injuries alleged in the underlying lawsuits were due to a gas explosion that was “caused, in whole or in part, by” the named insured’s acts or omissions. I. Background The additional insureds, Atlanta Gas Light Company and Southern Company Gas (collectively, “AGL”), retained the named insured, United States Infrastructure Corporation (“USIC”), to locate and mark gas lines that AGL owned in Georgia. USIC failed to mark a certain gas line, which was later struck by a boring company, leading to an explosion that injured three people. Reprinted courtesy of Kyle A.
