Widely considered to rank among the leading arbitration groups worldwide, Debevoise & Plimpton LLP’s US offering is a key contender for major, headline-grabbing cases across the globe. Equally adept at commercial and investor-state work, the New York-based team is routinely involved in landmark matters—across a comprehensive range of industries—on behalf of both corporate and state clients. Department co-chair Catherine Amirfar brings to bear extensive experience in high-stakes, public international law disputes and successfully represented Italian investors in ICSID proceedings against Albania arising out of the claimants’ investments in a hydroelectric plant and a media company. Fellow co-head Mark W. Friedman additionally co-leads the mining and natural resources practice; he paired up with increasingly prominent arbitration specialist Ina Popova to represent Gramercy Funds Management in a complete win on jurisdiction and merits in an UNCITRAL arbitration against the government of Peru under the US-Peru Trade Promotion Agreement (TPA). Other experienced names include Latin America practice co-head Dietmar Prager, who ‘stands out for his decisiveness and sharp intellect’; and Natalie Reid, who co-chairs both the public international law group and the Caribbean practice group. Talented up-and-coming names include next-generation partner Laura Sinisterra. David Rivkin has retired. Floriane Lavaud has left the firm.
