Justice Barry R. Ostrager
New York, NY

Barry R. Ostrager served as a New York State Supreme Court Justice in the Commercial Division, retiring on December 31, 2023 after eight and one-half years of judicial service. Prior to his appointment to the Bench, Justice Ostrager was a litigation partner at Simpson Thacher & Bartlett LLP and served as the long-time head in the Litigation Department.

Justice Ostrager was prominently involved in many high-profile securities, antitrust, and commercial cases, and was lead trial counsel in many major insurance coverage cases. He was lead trial counsel for Swiss Re in the highly publicized insurance coverage dispute involving the World Trade Center tragedy which resulted in a unanimous jury verdict in favor of Swiss Re, and lead counsel for Hanwha in a multi-billion-dollar dispute with the Korean government that was the subject of a multi-week trial. In all, Justice Ostrager successfully tried five cases to verdict involving $1 billion or more in dispute as well as dozens of other trials.

Justice Ostrager successfully argued before the United States Supreme Court the closely followed Epstein v. Matsushita case that arose out of Matsushita’s successful tender offer for MCA, Inc. He successfully argued again before the Supreme Court the Travelers v. Bailey case, which resolved important issues relating to the rights of settling insurers in asbestos-related bankruptcy.

Justice Ostrager also successfully represented Andersen Consulting against a $14 billion claim by Arthur Andersen in connection with Andersen Consulting’s successful bid to win a separation without cost from the Andersen Worldwide organization in the largest ICC arbitration in history. Among other successes as a trial attorney, Justice Ostrager represented J.P. Morgan Chase in a breach of guarantee contract action against Motorola in which J.P. Morgan Chase obtained a $370 million verdict against Motorola.  In 1993 Justice Ostrager was lead trial and appellate counsel for Paramount Communications in the widely publicized QVC v. Paramount tender offer litigation. Immediately prior to taking the bench, Justice Ostrager was actively involved as lead counsel for Countrywide Financial in mortgage-backed securities cases brought by FGIC and AMBAC in the New York state courts.

Justice Ostrager is co-author of the Handbook on Insurance Coverage Disputes (Wolters Kluwar 2022), a widely-used, three-volume treatise now in its 21st edition. He is also co-author of Modern Reinsurance Law and Practice, 3d. (LegalWorks 2014).

In June of 2006, Justice Ostrager was named the “Leading U.S. Litigation Business Trial Lawyer” by Chambers & Partners. For 11 consecutive years, Justice Ostrager was ranked by Chambers as a “Band One” General Commercial Litigator and “Band One” Insurance: Dispute Resolution Leading Lawyer. For 10 consecutive years (2005-2014), Justice Ostrager was recognized as one of the leading trial lawyers in the U.S. by The Legal 500, which frequently identified him as one of the “Top Ten Trial Lawyers” in the U.S. and as an “exceptionally effective cross-examiner” with “brilliant litigation skills.” Euromoney’s Benchmark Litigation also recognized Justice Ostrager as a “Litigation Star” for both General Commercial Litigation and Insurance Litigation (2010–2014).
