United States Steel Corp. v. Hartford Accident and Indemnity Co‪.‬

Plaintiff United States Steel Corporation (Steel) brought suit for declaratory judgment claiming insurance coverage under policies issued by the defendant, Hartford Accident and Indemnity Company (Hartford) and seeking damages for Hartfords breach of its duty to defend Steel in underlying state court actions. Three separate actions were consolidated and the district court granted summary judgment for Steel. Hartford appeals from the district courts declaration that Hartfords Comprehensive General-Automobile Liability Policy provided coverage for the claims brought against Steel in the underlying actions; that Hartford had breached its duty to defend in those actions, and that Hartford was obligated to pay the judgment secured; and from the award as damages of the amounts of Steels costs and expenses in defending the underlying actions. Jurisdiction is founded on diversity of citizenship and Illinois law controls substantive questions.
