GST LLP is a Miami-based firm with an intense focus on international arbitration, in particular investor-state and public international law disputes involving Latin American nations. While the firm’s practice covers a range of geographies around the world, Latin America remains its true forte, and it continues to be noted for its representation of sovereign states and investors in major headline cases. This includes acting for the Bolivarian Republic of Venezuela and its state-owned oil and gas entity Petróleos de Venezuela (PDVSA) in a number of disputes. Diego Gosis, Quinn Smith and Ignacio Torterola comprise a senior bench of genuine Latin America arbitration specialists.
With a decade in the market, highly regarded international arbitration boutique GST LLP is now an established market presence, regularly handling sizeable, high-impact cases globally. The firm recently strengthened its Latin American practice notably with the May-2021 hire of Venezuelan practitioner Carmine Pascuzzo as counsel in the Washington DC office; and the addition of Domenico di Pietro (from Bryan Cave Leighton Paisner LLP) as a partner at the London office the following month. Founding partners Ignacio Torterola (in Washington DC), and Diego Gosis and Quinn Smith (in Miami) co-lead the Latin America team, which acts primarily in ICSID, UNCITRAL and ICC proceedings – be it as counsel or arbitrators. In addition to commercial matters, the practice has developed a strong roster of sovereign clients, including Venezuela and Guatemala. An experienced and capable second line is led by Pablo Mori (in Washington, DC) and Katherine Sanoja (in Miami), who were both raised to counsel in May 2020. Associate Fabian Zetina is also noted.
