Whether the trial court erred by treating the policy's exterior-visible-marks definition of burglary as the sole and controlling basis for denying coverage.
Holding
Yes. The court applied an erroneous legal approach by enforcing the fine-print definition without considering the parties' bargain, the circumstances of the sale, and the legal consequences of a standardized insurance contract.
Reasoning
Contract construction is a question of law, so the Supreme Court was not bound by the trial court's legal conclusion that the policy definition alone controlled. Although supported factual findings ordinarily receive deference in a law action, that rule does not prevent appellate review when the findings or judgment rest on an erroneous rule of law.
Evidence of negotiations, the parties' circumstances, and the transaction's purpose was relevant to determining the agreement's actual significance. The trial court focused narrowly on whether the exterior-entry requirement was met and never determined whether a burglary occurred under either an ordinary person's understanding or Iowa's legal understanding of burglary.
Insurance policies are standardized adhesion contracts, usually drafted by insurers and delivered after the insurance is purchased. A buyer's assent therefore extends to the negotiated terms and to reasonable standard provisions, but not to hidden provisions that unreasonably alter or destroy the protection for which the buyer bargained.
