A first port of call for state-side mandates, Arnold & Porter leverages the firm’s prominent sovereign and government practice to excel in representing sovereign clients in investor-state arbitrations. Its preeminent reputation in this sphere is underpinned by its impressive success rate in investment arbitrations. The group also continues to increase its share of commercial disputes, with a focus on the life sciences and technology industries—its US West Coast arbitration practice is particularly noted for this type of work. From Washington DC, Paolo Di Rosa specializes in complex investment arbitration and recently teamed up with partners in Shanghai and Seoul to successfully defend the Government of South Korea in the first treaty-based investment arbitration ever filed against Korea. San Francisco based practice head Maria Chedid is one of two attorneys from the US currently serving as a US member of the ICC Court of Arbitration. In New York, Mélida Hodgson is recommended for Latin America-related disputes, where she has represented Venezuela, Panama and Peru, among other sovereigns. Additionally, Washington DC-based Whitney Debevoise is highly regarded for international finance disputes.
