In a recent trial court decision, a Montana federal court reminds us how fragile insurance coverage can be for construction-related insurance claims. Specifically, this case illustrates how seemingly small factual nuances can make or break coverage. The case turned on the application of policy provisions familiar to all who deal with these kinds of cases. (See Nautilus Ins. Co. v. Farrens, No. CV 22-193-M-DWM, 2024 WL 885109 (D. Mont. Mar. 1, 2024))

First, the court rebuffed the insurer’s argument that damage resulting from defective workmanship (in this case, the flawed design and installation of an elaborate floating-floor pool system) is not “caused by an occurrence.” The court correctly applied the test followed by most states: if either act causing injury is unintentional or the resulting injury is unexpected or unintended, the “occurrence” requirement is met. Fortunately, the court distinguished sloppy language from earlier Montana federal court decisions suggesting otherwise.
