Plaintiff Clarendon National Insurance Company (“Clarendon”) sued Atlantic Risk Management, Inc. (“Atlantic”), its third party claims administrator (“TPA”), based in part on its contention that it consistently relied on Atlantic’s coverage recommendations to its detriment. The trial court denied Atlantic’s motions to compel production of Clarendon’s claim files and copies of its reinsurance policies. The Appellate Division reversed, ordering Clarendon to produce all of its claims files for which Atlantic served as TPA, as well as copies of its reinsurance policies. The Court held that the claims files were relevant to plaintiff’s claims handling practices at issue, and that the reinsurance policies are required to be disclosed under New York’s procedural rule requiring production of all insurance policies which potentially cover the subject liability. Clarendon Nat’l Ins. Co. v. Atlantic Risk Mgmt. Inc., Nos. 5303N, 5303NA, 5303NB and 5303NC (N.Y. App. Div. Feb. 19, 2009).
