Great American Insurance missed a filing deadline by five days - and lost its shot at an early appeal of a ruling it wanted overturned.
On August 31, 2026, the Delaware Supreme Court refused the insurer's interlocutory appeal - an appeal taken mid-case, before a final judgment.
The dispute began with coverage. The policyholders, Big V Capital and related entities, had bought a policy from Great American and sought coverage for a derivative action started in 2024 - a suit shareholders bring on a company's behalf. On June 30, 2026, the Superior Court held that the 2024 action was covered. The finding favored the policyholders.
Great American wanted to challenge it right away rather than wait for the rest of the case to run its course. Delaware allows that kind of mid-case appeal only if a party asks the trial court to certify it inside a tight window. The rule requires the request "within 10 days of the entry of the order from which the appeal is sought or such longer time as the trial court, in its discretion, may order for good cause shown."
The clock started June 30. The deadline landed on July 10. Great American filed its certification application on July 15 - five days late - then filed a notice of interlocutory appeal on July 30. The policyholders opposed certification.
The Superior Court denied the application as untimely and noted the insurer never asked for an extension or showed good cause. The Supreme Court agreed and refused the appeal, citing recent cases where it turned away interlocutory appeals filed just three or four days past the deadline.
The refusal turned on the calendar, not the coverage. The court never touched whether the Superior Court read the policy correctly. It held only that Great American forfeited its early appeal by filing late. The coverage finding stands at the trial level, and the case is not over.
For insurers and coverage counsel, the takeaway is narrow but sharp: Delaware's ten-day certification window is counted strictly, extensions are not assumed, and a matter of days can strip a carrier of its chance to test an adverse coverage ruling before final judgment.
