Simon is “an absolute star”, a “phenomenal” and “remarkable” advocate who is “incredibly bright and drafts beautifully” (Chambers and Partners). He is the Chambers and Partners Banking Junior of the Year 2019, and has been shortlisted for that award a further three times in the past six years; he was also named a “Star of the Bar” by Legal Week.
He has been involved in some of the largest scale commercial litigation in recent years, both domestically and overseas. For example, during 2019 alone he has been involved in significant hearings in the Supreme Court, Court of Appeal and various High Court trials and interlocutory hearings, and two substantial arbitrations, as part of a team and as sole counsel. He is Ukraine’s junior counsel in the pending Supreme Court hearing defending a US$3billion claim against it arising from a loan arrangement with the Russian Federation in which his client was successful in the Court of Appeal (at first instance, one of The Lawyer’s top cases of 2017), but has a varied commercial practice: during 2019, he also represented a major pharmaceutical company in the trial of the largest claim for damages under a cross-undertaking under an wrongly granted injunction for alleged patent infringement, successfully represented the Claimant in the Court of Appeal after a (successful) three-month civil fraud trial in the Chancery Division arising from misappropriation of €100 million and involving allegations against solicitors, accountants and Swiss bankers and represented the Claimant in a substantial claim arising from an alleged investment fraud.
During the past few years, he was instructed in the Commercial Court trial of a claim against Mike Ashley for £14 million arising from an alleged oral agreement reached in a pub, the four-month Commercial Court trial of JSC BTA Bank v Ablyazov and others, two separate three-month fraud trials in Group Seven v Sultana (plus appeal) and Group Seven v Nasir and others (plus appeal), by the Central Bank of Trinidad and Tobago in the three-year Commission of Enquiry into the collapse of a multi-billion dollar banking and insurance conglomerate, in a series of interest rate swap and derivative disputes (including litigation arising from alleged manipulation of LIBOR), a major dispute arising from pollution of a river in Wisconsin (which settled, but which led to the litigation including BAT v Sequana) and the allocation of responsibility for the clean-up costs totalling hundreds of millions of dollars and acted for Barclays Bank (led by Iain Milligan QC/Jonathan Sumption QC and Andrew Mitchell) in the OFT bank charges litigation up to the Supreme Court. In addition to High Court litigation and arbitrations in the UK, he has recently been instructed in cases in the British Virgin Islands, Cayman Islands, Dubai, Hong Kong and Trinidad and Tobago.
Simon’s wider commercial practice has included instructions in relation to numerous large-scale commercial cases, including a substantial fraud claim involving multi-jurisdictional freezing orders (Intercontinental Bank v Akingbola, led by Michael Bloch QC), Bank of Tokyo-Mitsubishi AFJ v Ferrero Group and others  EWHC 1276 (Ch) (appellate stage), a $1bn Russian oil and gas dispute, a significant telecommunications dispute involving two of the world’s richest men and several large insurance disputes.
