Practice Overview

Marc was called to the Bar in 2011 following First Class degrees in Mathematics and in Law. His practice covers a wide range of Commercial and Civil Fraud litigation. He has particular experience of obtaining and resisting injunctions (both led and as sole counsel) and of cases which are international in nature or have a cross-border element, including jurisdiction disputes. He is regularly instructed in cases involving gambling and has experience of disputes involving cryptocurrency.

Marc is currently instructed for the defendant companies in a US$3billion+ commercial fraud claim, PrivatBank v Kolomoisky, Bogolyubov, Teamtrend Ltd & others, which is one of The Lawyer’s "Top 20 cases of 2022".

Marc is ranked as a leading junior barrister by Chambers and Partners (2024 edition) for three different practice areas: Commercial Dispute Resolution, Civil Fraud and Gambling Disputes. He is described as “very bright, with an encyclopedic knowledge of the law” and as a barrister whose “determination and tenacity is excellent and a real bonus in hard-fought commercial fraud litigation”.

In previous editions he has been described as “bright beyond his year of call and always seems to be a couple of steps ahead of the opposition”, as “very thorough, very precise and he is great on his feet”, and as a junior who “skilfully provides strategic and commercial input to augment his excellent technical advice” (2023 edition). He is regarded as “incredibly bright, very tactically astute” and a “well-prepared, understated advocate who is very measured” and it was noted that “judges respond well to his advocacy style” (2022 edition). He was acknowledged as having “a growing reputation for his handling of complex and high-value fraud disputes”, as being a “very capable junior who takes good points” (2021 edition).

The Legal 500 directory (2024 edition) recommends Marc as one of the country’s leading junior barristers for both Commercial Litigation and Civil Fraud law, in which he is described as “extremely thorough and his attention to detail is invaluable. Moreover, he has a good depth of knowledge of the law in this practice area, and he is strong on his legal analysis” (2024 edition). He received the following recommendations in previous editions: “extremely capable, bright and commercially minded” and “great to work with” (2023 edition); “a very good strategist and tactically astute. An impressive advocate and very good on his feet”, “very approachable, courteous and personable. Also incredibly thorough and comprehensive on paper”, (2022 edition); and “extremely bright, hardworking and knows his stuff”, “strong on the law and produces good quality work, both on paper and on his feet” (2021 edition).

As a Mathematics graduate, Marc is highly numerate and confident in tackling very technical and complex evidence.
