Case Brief Summary & Legal Analysis
tl;dr: An insured manufacturer argued its exploded pulp digester was “of a kind” with a “steam boiler” to gain coverage. The court rejected this contextual interpretation, holding that the rule construing ambiguity against the insurer is a last resort, applicable only after considering extrinsic evidence.
Legal Significance: This case clarifies that contra proferentem is a rule of last resort in contract interpretation. A court must first attempt to resolve ambiguity using extrinsic evidence before construing the contract against the drafter, even in the insurance context with a sophisticated insured.

Case Facts & Court Holding
Key Facts & Case Background
Stone Container Corporation, a manufacturer, operated a large steel pulp digester that used externally-generated steam under high pressure. The digester, an “unfired pressure vessel,” exploded, causing over $80 million in damages. Stone held a “boiler and machinery” insurance policy from Hartford Steam Boiler. The policy covered accidents to specifically enumerated “objects” but contained a general exclusion for losses caused by “explosions.” However, an exception to this exclusion restored coverage for explosions of certain listed objects, including a “steam boiler.” A steam boiler is a “fired pressure vessel” that creates its own steam, a functionally distinct engineering classification from Stone’s digester. After Hartford denied coverage, Stone sued, arguing that the digester was an object “of a kind” with a steam boiler and thus fell within the exception to the explosion exclusion. The district court found the policy ambiguous and granted summary judgment to Stone without allowing Hartford to present extrinsic evidence.
Court Holding & Legal Precedent
Issue: Under principles of contract interpretation, is an insurance policy term like “of a kind” ambiguous when it introduces a list of specific machinery types, and must the rule of contra proferentem be applied before the drafting party has an opportunity to present extrinsic evidence to resolve the alleged ambiguity?
No. The policy is not ambiguous when read contextually, and even if Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
