Three Crowns LLP is an international disputes heavyweight with a reputation for commercial, investor-state and state-to-state cases. Its new Madrid office, opened in autumn 2023, has resulted in an uptick in engagements from Spanish and Latin American clients; international arbitration leader Carmen Martinez Lopez heads the office with support from recently promoted partner Agustin Sanz and dual qualified (New York/Brazil) senior associate Laura França Pereira. The wider international arbitration team continues to represent a mix of states and multinationals in some of the largest investment treaty cases to involve Latin America, including representing the Republic of Chile in a $200m+ ICSID claim filed under the Chile-Colombia FTA, concerning the largest electricity transmission project in Chile’s history. The team also remains especially active in a broad array of commercial arbitrations. London based Gaëtan Verhoosel KC is a leading name in international arbitration with a substantial focus on Latin America, including commercial and investment treaty arbitrations; he recently represented Sacyr in a $1bn+ dispute relating to claims brought by a contractor for the Panama Canal Third Set of Locks project. Washington DC’s Luke Sobota is another key team member on a number of headline Latin America cases.
