Mountain States Mutual Casualty Company v. Roinestad

Respondents Christopher Roinestad and Gerald Fitz-Gerald were overcome by poisonous gases while cleaning a grease clog in a sewer near the Hog's Breath Saloon & Restaurant. The district court concluded that Hog's Breath caused respondents' injuries by dumping substantial amounts of cooking grease into the sewer thereby creating the clog and consequent build up of the gas. On summary judgment, the district court found the saloon liable under theories of negligence and off-premises liability and granted respondents damages. The saloon carried a commercial general liability policy issued by Petitioner Mountain States Mutual Casualty Company which sought a ruling it had no duty to indemnify Hog's Breath. The district court agreed that under the terms of the policy, the insurer had no duty under a pollution exclusion clause. The appellate court reversed the ruling in favor of the insurer, finding the pollution exclusion clause was ambiguous and that its application to cooking grease (a common waste product) could lead to absurd results and negate essential coverage. Upon review, the Supreme Court reversed, finding that the saloon released enough grease to amount to a discharge of a pollutant, and that the insurance policy pollution exclusion clause barred coverage in this case.
