  • Biography

    Jacob (Jack) Cohn is a partner in the firm’s Philadelphia office and serves as co-chair of the firm’s national Appellate Practice Group. Jack has thirty years of experience in all aspects of trial and appellate practice in both state and federal courts in a variety of complex, high-stakes cases. Currently, he focuses his practice on appeals, commercial litigation, policyholder bankruptcies, insurance coverage, and class action defense.

    In his appellate engagements, Jack has argued cases before numerous state and federal appellate courts, including the U.S. Supreme Court. He has obtained precedent-setting results for his clients in areas including insurance coverage and bad faith, class action defense, bankruptcy, civil rights, and constitutional law. His recent trial work includes winning a $3.1 million federal court breach of contract verdict in favor of a commercial client.

    Jack has spoken on topics such as insurance coverage, policyholder bankruptcies, and fidelity and surety law, and has written scholarly commentaries on a number of related issues. He has also been involved in tort reform efforts, including testifying before the Ohio House of Representatives in support of that state’s groundbreaking Asbestos Transparency Act, enacted in 2012.

    Representative Experience

    • Argued before the U.S. Supreme Court in Travelers Indemnity Company v. Bailey, 557 U. S. 137 (2009), a widely-followed case involving issues of bankruptcy jurisdiction and the finality of the original 1986 Johns Manville asbestos insurance channeling injunction. On remand to the 2nd Circuit, obtained a ruling that his client was never properly made a party to the original proceedings in a manner consistent with constitutional due process and therefore was not bound by the 1986 injunction, in Travelers Cas. and Sur. Co. v. Chubb Indem. Ins. Co. (In re Johns-Manville Corp.), 600 F.3d 135 (2d Cir. 2010).
    • Argued and won a 14-0 decision by the en banc Third Circuit overruling Graziano, a 30-year old precedent requiring that consumer disputes under the Fair Debt Collection Practices Act be made in writing, resolving a deepening circuit split on the issue, in Riccio v. Sentry Credit, Inc., 954 F.3d 582 (3d Cir. 2020) (en banc).
    • Represented the insurer in Rancosky v. Wash. Nat’l Ins. Co., 170 A.3d 364 (Pa. 2017), where the Pennsylvania Supreme Court established the legal standard for “bad faith” under that state’s 27-year old insurance bad faith statute.  Rejecting arguments by the insured, backed by the plaintiffs’ bar, to hold that mere negligence should suffice to expose insurers to punitive damages and attorneys’ fee awards, the Court adopted a standard that was well within the national mainstream. 
    • In a contract dispute, won a $3.1 million breach-of-contract verdict for a Mexican aquaculture company following a week-long bench trial in the U.S. District Court for the Southern District of New York.
    • Won complete reversal by the 11th Circuit of a $1.9 million jury verdict and attorneys’ fee award against an insurer in a first-party coverage dispute arising from hurricane damage to three apartment complexes on the basis that the plaintiff, a property management company, lacked a sufficient insurable interest to recover for physical damage to properties the company owned, but did not manage. The case was remanded for entry of final judgment in favor of the insurer. Banta Properties, Inc. v. Arch Specialty Ins. Co., 2014 U.S. App. LEXIS 1419 (11th Cir. Fla., Jan. 24, 2014).
    • Won Sixth Circuit affirmance of an Ohio district court’s exclusion of a damages expert on Daubert grounds and subsequent grant of summary judgment in favor of a patent servicing company that erroneously failed to pay annual maintenance fees in Japan causing a Japanese patent to expire prematurely, in ASK Chemicals, LP v. Computer Packages, Inc., 2014 U.S. App. LEXIS 23444 (6th Cir. December 10, 2014).
    • Won 3rd Circuit affirmance of the summary dismissal of a class action by medical providers challenging an automobile insurer's use of computerized fee review software to adjust claims for medical reimbursement in St. Louis Park Chiropractic, P.A. v. Federal Ins. Co., 342 Fed. App’x. 809, 2009 U.S. App. LEXIS 16299 (3d Cir., July 22, 2009).
    • Won summary judgment and prevailed on appeal before the Pennsylvania Superior Court rejecting a homebuilder's argument that CGL policies afford coverage for water damage caused by construction defects. Millers Capital Insurance Co. v. Gambone Brothers Development Co., 941 A.2d 706 (Pa. Super. 2007). This decision has been repeatedly cited by the 3rd Circuit and other state and federal courts as a leading precedent in this area of the law.
    • Obtained 2nd Circuit affirmance of a ruling that the September 11 attacks on the World Trade Center constituted one, rather than two, occurrences for insurance purposes, saving an insurance company $254 million. SR International Business Insurance Co., LTD. v. World Trade Center Properties, 467 F.3d 107 (2d Cir. 2006).
    • Won reversal of a trial court’s holding in a class action suit, brought by radiologists, that New York's no-fault automobile insurers could not deny reimbursement for MRI scans on grounds of lack of "medical necessity." Long Island Radiology v. Allstate Ins. Co., 830 N.Y.S.2d 192 (2d Dept. 2007).
    • In a pro bono representation, obtained a $250,000 settlement for a woman with AIDS after the viatical settlement company that purchased her life insurance policy tried to renege on its contractual obligation to continue paying the woman's health insurance premiums because she had survived for too long.
    • Additional representative matters include: Steadfast Ins. Co. v.Eon Labs Mfg., Inc., Del.Super. LEXIS 272 (Del. Super., June 1, 1999), aff'd sub nom., Eon Labs Mfg., Inc. v. Reliance Ins. Co., 756 A.2d 889 (Del. 2000); Jordan v. Fox Rothschild, O'Brien & Frankel, 20 F.3d 1250 (3d Cir. 1994);Collins v. Upper Salford Twp., 669 A.2d 335 (Pa. 1995).
