Stout Risius Ross LLC asked for a declaratory judgment to require Aspen Specialty Insurance Co. to defend Stout Risius Ross in a lawsuit brought against it by its former client, Wilmington Trust, in an ESOP matter. Stout Risius Ross performed a valuation for an ESOP transaction that the court later criticized in that matter (Brundle). After being sued by Wilmington Trust, Stout Risius Ross filed a claim with Aspen, which was denied by Aspen, citing the “prior knowledge” clause. The court denied Stout Risius Ross’ motion for declaratory judgment and did not allow Stout Risius Ross to amend its motion.
