City of West Liberty v. Employers Mutual Casualty Co.Annotate this Case
The Supreme Court affirmed the decision of the district court granting summary judgment to the insurer in this coverage dispute, holding that an electrical-currents exclusion in the policy applied to the loss in this case.
A squirrel climbed onto an outdoor electrical transformer at the City of West Liberty’s power plant, eventually triggering an electrical arc that caused substantial damage to the City’s property. The City sought coverage from Employer’s Mutual Casualty Company (EMC) under its all-risks insurance policy. EMC denied coverage based on the electrical-currents exclusion in the policy, which excluded “loss caused by arcing or by electrical currents other than lightning.” The City sought a declaratory judgment of coverage and damages, arguing that the squirrel was an efficient proximate cause of the loss, and therefore, two independent causes, one covered and one excluded, contributed to the loss. The district court disagreed and granted summary judgment to EMC. The Supreme Court affirmed, holding that the loss here was “caused by arcing” and therefore was excluded even though the squirrel triggered the arcing.
