Jayme Jonat is involved in numerous large-scale litigation efforts that, in addition to their considerable monetary stakes, have tested new legal theories and affected business practices across entire industries.


They include defending Visa in antitrust litigation against many of the world’s largest retailers; representing a government-owned pension fund in claims against the world’s largest life insurance carriers; and assisting Judge Holwell in his role as an independent monitor appointed by a major financial institution under an agreement between the institution and the U.S. Securities and Exchange Commission. Jayme also represented French industrial company Alstom in litigation against GE concerning the most significant French M&A transaction of 2014.


Given the size of her clients and the scope of their business activities, many of her matters have international components. In addition to advising on FCPA matters, Jayme has litigated multiple disputes arising from corporate transactions with cross-border implications.


Jayme also has an active pro bono practice. With the Bronx Defenders, for example, Jayme successfully appealed a client’s felony conviction for which he was unjustly sentenced to five years for attempting to steal a bicycle, resulting in his release from state prison. Working alongside Sanctuary for Families on the Queens Human Trafficking Intervention Project, Jayme provided legal advice and access to a wide range of social services to victims of sex trafficking. And today, working with the American Civil Liberties Union, Jayme represents female pilots and flight attendants in two first of their kind workplace discrimination lawsuits against Frontier Airlines for its systemic failure to accommodate pregnant and breastfeeding employees.


Jayme was named a Litigation Trailblazer by The National Law Journal in 2020 and was recognized on Profiles in Diversity Journal’s 2018 Women Worth Watching list. Before joining HSG, she was a litigation associate at Davis Polk & Wardwell LLP and clerked for the Honorable Arthur D. Spatt of the United States District Court for the Eastern District of New York. She was promoted to partner in 2019.
