WAUKESHA, Wisc. - An insurer that issued a contractors pollution liability policy to its insured does not have a duty to defend or indemnify the insured for underlying property damage and bodily injury claims caused by a natural gas line explosion because the underlying suits allege damages caused by the explosion and fire and not by contact with the natural gas, the Second District Wisconsin Court of Appeals said March 12 (Acuity, A Mutual Insurance Co. v. Chartis Specialty Insurance Co., No. 2013AP1303, Wis. App., Dist. 2; 2014 Wisc. App. LEXIS 201).
