Background

An explosion and fire at an oil and gas well owned and operated by XTO Energy killed one contractor and severely injured several other workers. After the victims sued XTO, Missouri Basin, and others, XTO defended and indemnified Missouri Basin under their contractor agreement and sought coverage under a second-layer umbrella policy that Commerce and Industry Insurance Company had issued to Missouri Basin.

Commerce denied coverage under a pollution exclusion applicable to bodily injuries arising from the release or escape of pollutants. The district court found that oil and gas qualified as pollutants but held that a time-element exception restored coverage because Commerce had waived reliance on XTO’s failure to report the incident within the exception’s 21-day deadline and had not shown prejudice. It ultimately awarded XTO $25 million, plus prejudgment interest, attorney’s fees, and costs.

The Court’s Holding

The Eighth Circuit reversed. It held that the pollution exclusion unambiguously covered the underlying bodily-injury claims because the workers were injured when oil and gas—pollutants under the policy—were released and ignited. XTO bore the burden of establishing the time-element exception, but admittedly failed its condition requiring written notice to Commerce within 21 days after the incident became known to the insured.

The court held that North Dakota’s statutory waiver rule for delayed notice did not apply because Commerce denied coverage under the pollution exclusion, rather than asserting late notice as an independent defense. Commerce also did not have to prove prejudice: unlike the indefinite notice provision considered in Finstad, this policy imposed a definite deadline and clearly made timely notice a condition of the exception. Finally, Commerce’s follow-form provision did not import the underlying Berkley policy’s hostile-fire and additional-insured exceptions because Commerce’s own conflicting pollution-exclusion terms controlled. The court vacated the awards of damages, interest, attorney’s fees, and costs.

Key Takeaways

  • An insured seeking the benefit of an exception to a policy exclusion bears the burden of proving that every condition of the exception is satisfied.
  • North Dakota’s waiver rule for late-notice defenses did not transform a notice condition within an exclusion exception into an independent late-notice defense.
  • No showing of prejudice was required where the policy set a definite reporting deadline and unambiguously made compliance necessary for the exception to apply.
  • A follow-form umbrella policy does not incorporate underlying-policy provisions that conflict with the umbrella policy’s own terms and exclusions.

Why It Matters

The decision distinguishes between notice required as a general condition of coverage and notice required to invoke an exception to an otherwise applicable exclusion. Under the Eighth Circuit’s reading of North Dakota law, courts must enforce a clear deadline in the latter setting without adding waiver or prejudice requirements absent from the policy.

The ruling also underscores that follow-form language does not automatically carry every favorable exception from an underlying policy into excess coverage. Attorneys must compare each policy layer’s exclusions and exceptions because the excess policy’s conflicting terms may narrow coverage.
