ST. PAUL, Minn. - A Minnesota appeals court on June 25 affirmed a trial court's decision granting summary judgment in favor of an insurer, finding that homeowners that sought coverage for damage caused by a vapor barrier failed to show that their losses were not excluded from the coverage available under the policy (Jerome Koskovich, et al. v. American Family Mutual Insurance Co., No. A11-2206, Minn. App.; 2012 Minn. App. Unpub. LEXIS 581).
