Grinnell Mutual Reinsurance Co v. Great Lakes Insurance SE, No. 21-2712 (8th Cir. 2022)
Annotate this Case
MNDKK, LLC’s insurer, Great Lakes Insurance, sent subrogation demands through an assignee to Dingmann Brothers Construction (“Dingmann”) due to alleged dust-related property damage. Grinnell Mutual Reinsurance Company (“Grinnell”), Dingmann’s insurer, commenced a declaratory-judgment action to determine coverage under the insurance policy issued to Dingmann. The district court granted Grinnell’s motion for summary judgment, holding that two policy exclusions unambiguously apply due to the presence of silica in the dust and that coverage is foreclosed. Defendants argued that the two exclusions do not apply, meaning Grinnell is responsible for covering the cost of the property damage caused by the dust.
The Eighth Circuit affirmed the district court’s ruling and held that there is no genuine dispute of material fact about whether the dust contained silica. Further, Defendants argued that the cleanup provision does not apply because the damage was due to silica or silica-related dust itself, not its effects. Defendants claimed that there is a misplaced comma between “effects of” and “silica.” The court held that the comma before “silica” indicates that the phrase “the effects of” belongs with the phrase immediately preceding it, rather than with “‘silica’ or ‘silica-related dust.’” So, the last verb phrase in the series is “or in any way responding to or assessing the effects of,” and the comma separates the series from the noun phrase that is its direct object. Finally, the court held overlapping provisions can exist in an insurance policy and that both the cleanup and property-damage provisions apply.
Court Description: [Gruender, Author, with Benton and Erickson, Circuit Judges] Civil case - Insurance. The policy in question excluded coverage for dust damage if the dust contained silica, which the dust in question here did, and the district court did not err in concluding the policy exclusions foreclosed coverage.
