California’s complex saga of long-tail injury coverage under general liability policies took an interesting turn in the California Supreme Court’s recent decision in Truck Ins. Exch. v. Kaiser Cement.¹ In Truck, the court made it clear that Insureds can access excess policy limits without first exhausting all triggered underlying primary coverage, provided the underlying limits for the same policy period have been exhausted.

A Brief Summary of the History of Coverage for Long-Tail Claims in California²

Understanding the contextual significance of Truck requires a brief survey of California’s gradually developed case law with respect to long-tail progressive injury and damage claims. A “long-tail claim” typically involves progressively manifesting damage, injury, or disease that develops over a period of multiple years. Because general liability insurance is traditionally triggered based on the timing of when bodily injury or property damage occurs, the progressive nature of these claims has led many courts to analyze when injury or damage occurs in these claims. In doing so, California courts have generally found that these injuries occur across numerous years, thereby triggering numerous policies.³
