An appellate team led by Tom Dupree of Gibson, Dunn & Crutcher helped AIG subsidiary National Union fend off claims for coverage stemming from emissions of the carcinogen ethylene oxide over a 35-year period from a medical-supply sterilization plant in Chicago suburb Willowbrook, Illinois. The Seventh Circuit previously routed a question to the Illinois Supreme Court about whether a permit or regulation authorizing emissions had any effect on the pollution exclusions that are standard in general commercial liability policies. After the state high court answered unequivocally in the negative, Seventh Circuit this week found the exclusion applied to the policies in question and remanded the case to the trial court with instruction to enter judgment for National Union. The team representing the insurer includes Gibson Dunn partner Nick Harper, associates Aaron Hauptman and Aly Cox, as well as Gary Svirsky of O’Melveny & Myers and AIG in-house counsel Steven Rosenstein and Nick Schaefer.
