Stonewall Ins. Co. v. E.I. du Pont de Nemours & Co.
Stonewall Ins....(Del., Contracts, Insurance Law) In an action against an insurer seeking coverage for underlying litigation involving defects in a product for use in polybutylene plumbing systems, partial judgment for both parties is affirmed in part where 1) plaintiff’s production of an unsuitable product triggered only one single occurrence under the policies; and 2) the motion judge correctly applied the unambiguous noncumulation clause and reduced defendant’s liability properly. However, the judgment is reversed in part where the trial court incorrectly calculated the prejudgment interest accrual date.
