Three Crowns LLP

Exclusively active in international disputes, Three Crowns LLP‘s London office acts for corporations in heavyweight investor-state proceedings brought against states, including matters that are not treaty-based. The team also defends states against claims. The practice is co-led by the ’extremely sharp and convincing’ Constantine Partasides KC, who regularly obtains multibillion-dollar awards and is increasingly involved in arbitration-related litigation; and Gaëtan Verhoosel, who has a strong track record in complex investment treaty cases. The team further showcases Middle Eastern disputes specialist Reza Mohtashami KC, who acts for oil supermajors, construction firms, sovereign states and state entities; Manish Aggarwal, an expert in investor-state arbitrations under both UNCITRAL and ICSID rules; and Leilah Bruton, who ‘has amazing attention to detail’. Other names to note are energy disputes practitioner Hamid Abdulkareem; Farouk El-Hosseny, a specialist in commercial and investor-state disputes in the telecoms and oil and gas sectors; and Ridhi Kabra, who acts in investment treaty arbitrations in relation to taxation, infrastructure, telecoms, joint ventures, and oil and gas disputes. Carmen Martinez Lopez relocated to the firm’s Madrid office in October 2023.
