A group of insurance companies has sued another group of insurers, seeking a declaration that the defendants are also required to indemnify and defend flavoring companies that have been named as defendants in lawsuits by former microwave popcorn- and candy-plant employees alleging injuries from exposure to diacetyl. Arrowood Indem. Co. v. Atl. Mut. Ins. Co., No. 10600881 (N.Y. Sup. Ct., N.Y. County, filed April 7, 2010). While the plaintiffs anticipate that additional diacetyl exposure lawsuits will be filed, they allege that they have been defending, subject to a reservation of rights, seven cases already filed in Illinois, Missouri, Montana, and Ohio. The plaintiffs contend that the defendants have either wrongfully denied any coverage obligations or refused to respond to requests for contribution to the litigation defense or indemnity costs. Seeking declaratory relief, the plaintiffs also ask for damages, attorney’s fees, interest, and costs.
