Cleary Gottlieb Steen & Hamilton

Cleary Gottlieb Steen & Hamilton’s international arbitration practice draws on ‘an outstanding mixture of seasoned professionals and hard-working staff’, according to sources. Split between New York and Washington DC, the US group additionally plugs into the firm’s extensive global network to represent clients worldwide on commercial and investor-state cases, with a notable emphasis on Latin America. The department is co-led from New York by Ari MacKinnon, who focuses on Latin America-related disputes; he is representing Pluspetrol Resources Corporation in a Spanish-language ICC arbitration initiated by Peruvian state-owned oil company, Perupetro. Department co-chair Jeffrey Rosenthal, also in New York, maintains a broad dispute resolution practice that spans a range of judicial and arbitral matters, with recent activity in post-merger disputes, treaty cases, joint venture disputes and securities issues, among others.
