Supreme Court of Delaware
National Union Fire Insurance Company of Pittsburgh, PA v. Mattel, Inc.
August 27, 2025
Summary
The Supreme Court of Delaware refused National Union's application for interlocutory review of an order addressing insurance coverage allocation for claims involving Mattel's Rock ’n Play Sleeper. The Court held that interlocutory review was not warranted because the issues concerned only one of nine policy years and two of more than fifty policies, and National Union showed neither urgent need nor irreparable harm. The Court also concluded that the potential benefits of review did not outweigh the disruption and costs of a piecemeal appeal.
