About Ed
A warhorse well into his fourth decade as a New York City litigator, Ed has a distinguished record representing businesses in commercial litigations, arbitrations, and consumer financial services disputes. He has successfully defended companies against consumer class actions, including leading a Hinshaw team to a landmark US Supreme Court victory that upheld a class-action waiver in a student loan after the lower courts had struck it down.
With over thirty years of arbitration experience, Ed serves as counsel in domestic and international arbitrations and judicial confirmation proceedings, and as an arbitrator. He is well- versed in the New York Convention. Since his landmark victory in the US Supreme Court, he has drafted bespoke arbitration agreements for consumer finance contracts that incorporate class-action waivers and provisions limiting the risks of mass arbitrations. He co-authored the ARIAS-US International Arbitration Form for use in reinsurance contracts and prepared the arbitral provisions for a first-of-its-kind contract between a state and a Native American tribe permitting the latter to sell cannabis.
Ed has also shaped key precedent on sovereign immunity in international arbitration. He convinced a federal appellate court that a reinsurer owned by a foreign government had waived immunity from posting pre-award security. Earlier, he persuaded a federal district court that, under the New York Convention, foreign, state-owned reinsurers cannot invoke sovereign immunity under the US Foreign Sovereign Immunities Act (FSIA) to avoid posting the security required by New York’s insurance law when seeking to vacate an adverse award.
Areas of Focus
Experience
- Secured an order of the US Supreme Court that enforced the class action waiver in a student loan's arbitral provisions and vacated the decision of the federal Circuit Court of Appeals, which had deemed the waiver unenforceable under California’s now defunct Discover Bank rule. Affiliated Computer Services, Inc. v. Fensterstock, 564 US 1001 (US 2011). This landmark order was a front-page story in The New York Law Journal on June 14, 2011.
- On remand from the Supreme Court’s decision that a student loan’s class action waiver must be enforced, established in the trial court that, under the doctrine of estoppel, the loan's servicer was entitled to invoke the class action waiver of the promissory note even though the servicer was not itself a party to the note. Fensterstock v. Educ. Fin. Partners,. 2012 U.S. Dist. LEXIS 124571, 2012 WL 3930647 (S.D.N.Y. Aug. 30, 2012)
- In an interlocutory appeal by the other party in a confirmation action falling under the New York Convention, convinced the US Court of Appeals for the Eleventh Circuit to dismiss the appeal of the trial court’s decision that it had personal and subject matter jurisdiction over the party that appealed. Noble Prestige Ltd. v. Craig T. Galle, et al., 83 F.4th 1366 (11th Cir. 2023)
- After remand from the Eleventh Circuit Court of Appeals, won judgments totaling almost $10 million based on arbitral awards issued by the Hong Kong International Arbitration Centre. Noble Prestige Ltd. v. Craig T. Galle, et al. (S.D. Fla.)
- In a dispute involving co-location services, persuaded the US Court of Appeals for the Second Circuit to uphold the trial court’s decision that his client, a top business process solutions company, validly terminated the co-location contract. AiNET Corp. v. Xerox State & Local Sols., Inc., 739 Fed. App'x. 68, 2018 U.S. App. LEXIS 28611, 2018 WL 4927957 (2d Cir. Oct. 18, 2018)
