Ricky Diwan QC
Ricky Diwan QC has a wide-ranging practice in the fields of international commercial litigation, international commercial arbitration and international investment arbitration, as well as arbitration applications before the courts. He appears both before the English Courts, foreign Courts and in international arbitrations in London and abroad and has substantial experience in dealing with multi-jurisdictional disputes.
He has acted in arbitrations under a wide variety of international arbitration rules including HKIAC, ICC, ICSID, LCIA, SCC, SIAC, UNCITRAL and VIAC. He has vast experience of arbitration applications before the Court (including applications under s.67, s.68 and recognition and enforcement under the New York Convention) and has acted in a number of cases giving rise to important judgments. This includes Griffin v Poland  1 Lloyd’s Rep 410, where he acted for the investor in successfully setting aside an investment award on jurisdictional grounds, being the first investor state award to be set aside by the English High Court (for which he was nominated for an award by GAR in 2019); Kabab-Ji v Kout Food Group  EWCA Civ 6, where he acted for the Respondent before the Court of Appeal in successfully resisting recognition and enforcement of ICC arbitral award (the case is presently pending before the Supreme Court); Montrose & Eyre v Democratic Republic of Sri Lanka (ICSID Case No. ARB/16/25) where he successfully resisted an investment claim on jurisdictional grounds both before the originally constituted tribunal and the annulment committee (decision rendered on 2 December 2020); PAO Tatneft v Ukraine  EWHC 3161, where he successfully enforced a USD 81 million award under the New York Convention.
He also regularly sits as arbitrator in international arbitrations (both as co-arbitrator, sole arbitrator and chair) in commercial and investment arbitration and is presently appointed in arbitrations under the ICC Rules, LCIA Rules and SIAC Rules.
He is a member of the HKIAC and SIAC Panel of Arbitrators, and a member of the UK ICC Committee and co-authored the ICCA International Handbook on Commercial Arbitration for England & Wales (2015). He also co-drafted the Mauritian International Arbitration Act 2008, advised on the LCIA-MIAC arbitration rules and sits on the advisory board of the Mauritian International Arbitration Centre.
He is highly recommended in leading legal guides in which he has been described as “exceptionally sharp and extremely pleasant to work with”, “widely recognized and recommended figure in the market” and that “his understated but powerful performance at hearings is advocacy at its best”. He was short listed for the silk of the year in international arbitration by Chambers & Partners (2020) and short listed for the GAR Awards (2019) for his successful setting aside of an investment arbitral award (the first time an investment award has been set aside in this jurisdiction). He has lectured in international arbitration at King’s College, London, and regularly speaks at international arbitration events.
Prior to being called to the bar and joining Essex Court Chambers in 1998, he was admitted to the New York Bar and practiced as a qualified attorney-at-law at Debevoise & Plimpton (New York) between 1995 and 1997.
