Margaret M.Toohey

Margaret Toohey collaborates with clients, experts, and foreign co-counsel to get results in complex and cross-border disputes. She handles "bet-the-company" cases, including class actions and multibillion-dollar claims, on both the plaintiff's and defense side.

Margaret focuses her practice on disputes in the raw materials, manufacturing, construction, and pharmaceutical sectors. She has particular experience handling force majeure and other business interruption claims, including claims relating to plant accidents, the COVID-19 pandemic, and the conflict in Ukraine and related sanctions against Russia. She also has litigated multiple cases involving environmental contamination (air, soil, and groundwater), manufacturing or design defects, and anticompetition allegations.

Margaret has taken more than one dozen matters to final hearings on the merits. Her international arbitration experience includes disputes under the AAA, CPR, ICAC, ICC, ICDR, and LCIA rules, applying U.S., EU, Brazilian, Italian, Russian, Spanish, and Swiss substantive laws (among others). Her cross-border litigation experience includes parallel group litigation across multiple continents and Section 1782 discovery in the Fifth, Seventh, Ninth, Tenth, and Eleventh Circuits. Margaret has first- or second-chaired dozens of depositions, direct- and cross-examined witnesses, and is experienced at working with fact and expert witnesses throughout the life of a case.

Equal parts advocate and advisor, Margaret routinely counsels clients as commercial challenges arise with an eye to avoiding disruptive lawsuits. She also maintains an active pro bono practice, securing asylum on behalf of political dissidents.

Margaret's civic engagement includes serving on the Young Professional Committee of EDWIN's Restaurant & Leadership Institute.
