What the court held

And because, as pertinent here, the Federal Policies can be triggered only by occurrences that are 14 "not covered" by Reliance's policies or when the underlying limits have been exhausted, we answer the certified question in the negative.

Quoted from the court's own holding or syllabus. Confirm against the linked opinion before relying on it.

Key passage

“The policies at the heart of the parties' dispute require the umbrella/excess carrier to defend against any occurrence "not covered" by the insured's primary policies. The umbrella/excess carrier and the insured offer competing interpretations of "not covered," each yielding a different outcome.”

Why this matters

The opinion is published, so it binds Colorado trial courts until the court revisits it. This decision may affect how insurers, policyholders, and claims teams evaluate coverage, defenses, and available remedies.
