In 2017, the Missouri Supreme Court handed down its Doe Run decision, where it interpreted, as a matter of first impression, an insurance policy’s so-called “absolute pollution exclusion,” holding that it barred coverage for environmental-degradation claims arising from the release of toxic industrial byproducts. We believe this policyholder-adverse decision is limited by its facts and reasoning, and thus policyholders can still invoke the earlier and more favorable Hocker Oil and Wyatt decisions when seeking insurance coverage in other contexts.
