Three Crowns is pleased to announce being named a “Significant Player” for the second year in a row in the India Business Law Journal (IBLJ) report on the leading foreign law firms for India-related work, which is based on an analysis of more than 600 law firms. The ranking recognises the firm’s extensive expertise in high-value and complex arbitrations with an Indian connection across a wide variety of sectors, including energy, telecoms, real estate, infrastructure, and financial services.

In naming Three Crowns a leader, IBLJ notes the firm has several India-qualified lawyers and India specialists across the firm’s offices and a strong advocacy unit, led by partners who frequently are engaged for India-related disputes: Constantine Partasides QC, Gaëtan Verhoosel, Reza Mohtashami QC, and Manish Aggarwal. Peers note that Three Crowns is “an exceptional firm,” “one of the best firms to work with on arbitration-related matters,” and “top notch; high-quality and expert-driven, yet focused on practical solutions.”


Partasides has appeared as counsel on some of the largest commercial arbitrations of the last decade and has also advised and represented a variety of investors and States in relation to disputes under relevant bilateral and multilateral investment treaties.

Verhoosel is the Co-Chair of the IBA Arbitration Committee and was appointed to the ICSID Panel of Arbitrators by the Kingdom of Belgium. He teaches international investment law at King’s College School of Law in London.


Mohtashami has represented clients as counsel and advocate in more than 80 arbitrations conducted under a variety of arbitration rules in many different jurisdictions. He has particular expertise in disputes arising in emerging markets, including India.
