Related-claims disputes are a recurring feature of insurance coverage litigation, and the consequences can be substantial. A determination that two matters are related can shift a claim into or out of the policy period, altering coverage entirely. Although those disputes often involve fact-specific questions, the coverage outcome also depends on the applicable policy language. Urena v. Travelers Casualty and Surety Company of America, 2026 WL 2322160 (1st Cir. Aug. 11, 2026) underscores this point and offers significant guidance for policyholders navigating related-claims issues.

The First Circuit recently held that a “Special Hazard and Fluids Limitation Endorsement” was ambiguous and therefore there was excess coverage for a fuel spill that occurred after a tanker-truck overturned.

In Performance Trans. Inc. v. General Star Indem. Co., the First Circuit reversed the District Court’s grant of summary judgment in favor of General Star Indemnity Company. The District Court held that the excess policy General Star issued to Performance Trans. Inc. precluded coverage for a spill that resulted in the leaking of thousands of gallons of fuel. The District Court relied on the existence of a total pollution exclusion to bar coverage and held that the policy’s Special Hazards and Fluids Limitation Endorsement could not create an ambiguity that would afford coverage.
