International arbitration in Latin America: International firms

Arnold & Porter

The international arbitration practice at Arnold & Porter has a strong track record in investor-treaty matters and has adopted a policy of representing sovereign states in such cases. The practice is currently representing Peru in six arbitrations and has been retained by Colombia to act on a further two cases. The team is also working on high profile matters in infrastructure and transportation for Panama and Chile. Although state clients dominate its roster, the firm also represents corporates in the construction, infrastructure and aviation sectors. Washington-based Paolo Di Rosa heads the firm’s international arbitration practice and has extensive experience advising Latin American sovereigns across a 25-year career. Other investor-state specialists on the team include London-based Patricio Grané Labat, who also has significant international commercial arbitration experience; Mallory Silberman in Washington, who has been prominent in the firm’s work for Panama; senior partner Whitney Debevoise (who -like Di Rosa- is on ICSID’s panel of arbitrators) and has also worked closely on Panama-related matters, and like Raul Herrera, combines international arbitration expertise with experience in capital markets and transactional work. The practice was further strengthened in June 2021 with the hire of experienced, Latin America-focused counsel Alvaro Nistal, from Volterra Fietta, but subsequently endured the significant loss of Gaela Gehring Flores who exited to Allen & Overy in September. Since publication the firm has reinforced the team with the significant January-2022 hire of Mélida Hodgson, formerly arbitral practice head at Jenner & Block LLP.
