Northbrook Excess & Surplus Insurance v. Chubb Group of Insurance Companies
This declaratory judgment action addresses the hierarchy of excess insurance policies in a situation where one policy is primary for owned vehicles but excess for non-owned, and the second is an umbrella policy covering multiple risks. The case stems from an accident involving a rented van, which led to a $650,000 settlement. After the primary insurer paid $500,000, Chubb Group of Insurance Companies and Northbrook Excess and Surplus Insurance Co. each contributed $75,000, pending a determination of their respective excess coverage obligations. The Supreme Court initially ruled for ratable contribution. However, citing State Farm Fire & Cas. Co. v LiMauro, the appellate court reversed, holding that Northbrook's umbrella policy constitutes a final tier of coverage, not required to contribute ratably with Chubb's excess policy. Consequently, summary judgment was granted to Northbrook, entitling it to a $75,000 reimbursement from Chubb.
