Ricky Diwan QC is a leading practitioner in the field of international commercial and investment arbitration and related court applications. He appears as counsel in international commercial and investment arbitrations both in London and many different arbitral seats abroad under a wide variety of laws and arbitral rules (including ICC, LCIA, SIAC, UNCITRAL and ICSID). He has substantial experience of seeking emergency relief under both the LCIA and ICC Arbitration Rules and making related relief claims before the English Court. He also regularly sits as an arbitrator in international arbitrations. Being an OCI (Overseas Citizen of India) he regularly visits India and is able to provide services to Indian clients in India at short notice (given the absence of visa requirements or restrictions). He regularly appears before the English Court at all levels and has argued many applications under the Arbitration Act 1996 relating to jurisdiction (s.67), procedural irregularities (s.68) and recognition and enforcement domestically (s.66) and under the New York Convention 1958 (s.100 and following).
He is currently writing a practitioner’s text on the Arbitration Act 1996 and Common Law Principles of Arbitration, which will be published by Oxford University Press (which will likely be published in early 2020) and is one of the co-authors for the next edition of Mustill & Boyd. He co-drafted the Mauritian International Arbitration Act 2008 and advised on the LCIA-MIAC arbitration rules. He co-authored (with VV Veeder QC) the ICCA International Handbook on Commercial Arbitration for England & Wales published in December 2015.
He has been consistently recommended in leading legal guides in international arbitration. In the 2018 Chambers & Partners Guide he was described as “highly regarded for his international arbitration practice, which concentrates on commercial and investment issues”; in the 2017 Who’s Who Legal UK Bar he was described as: “ draw[ing] praise for the rate at which he has developed a very strong practice in both international commercial and investment arbitration with one source claiming, “He is one of the best young silks around”. In the 2016 Who’s Who Legal UK Bar it was said: “Outstanding Ricky Diwan QC emerges as one of the leading lights in our research and specializes in international commercial arbitration both in London and abroad under a range of laws.” In Chambers and Partners (2017) he was ranked in the field of international arbitration and described as “meticulous, extremely hard-working and always on top of all the detail.”
