Aetna Casualty & Surety Co. v. Greater New York Mutual Insurance
This case involves an appeal concerning an insurer's claim for contribution. Aetna Casualty & Surety Company, the liability insurer for Trio Drug Corporation and additional insured 58 Realopp Corporation, sought contribution from Greater New York Mutual Insurance Company, Trio's workers' compensation carrier. Aetna had settled an underlying injury action where it represented both Realopp and Trio, and subsequently sued for 50% of the settlement amount. The Supreme Court affirmed the denial of Aetna's summary judgment motion and the granting of Greater New York's cross-motion for summary judgment. The appellate court applied the anti-subrogation rule, finding that Aetna could not assert a subrogated claim against its own insured, Trio, due to potential conflicts of interest arising from its dual representation in the underlying action.
