Practice overview

Already described in The Legal 500 as a fantastic senior-junior, Jack has a busy commercial and chancery practice with significant experience acting in high value and complex disputes regularly in cases involving an international dimension, often appearing on his own against KCs or senior junior barristers. In particular Jack’s practice includes civil fraud disputes, company and insolvency, trusts, breach of fiduciary duties, professional liability as well as property-related work. Equally comfortable working on his own or as part of a larger team, he has significant advocacy experience appearing as sole counsel in a wide range of matters in his own right in the High Court, appellate Courts and Courts of foreign jurisdictions.

Jack is ranked in both The Legal 500’s and Chambers & Partners as a leading junior.

Jack is a former European Debating Champion and his published written work has been described as ‘illuminating’ in the Privy Council (Paponette v A-G of Trinidad and Tobago [2010] UKPC 32 per Lord Brown) and been cited approvingly by the Court of Appeal for Northern Ireland (Re Loreto Grammar School [2012] NICA 1) and again by the Privy Council (United Policyholders Group v Attorney General of Trinidad and Tobago [2016] UKPC 17).

Commercial disputes

Jack was ranked in The Legal 500’s top ten for commercial litigation under eight years’ call and has extensive experience of civil fraud, asset recovery, insolvency and company and partnership disputes as well as associated regulatory and financial services issues. Jack is also presently instructed in relation to a number of unfair prejudice petitions and has particular experience in relation to the overlap between fraud claims and insolvency.

Jack’s work has considerable experience of fund disputes as well as freezing injunctions (both seeking and responding to) and Norwich Pharmacal and other pre-action disclosure applications.

Jack’s recent experience of civil fraud/insolvency work includes:

  • Vneshprombank v Bedzhamov: Acting as junior counsel (with Alan Gourgey KC) in proceedings relating to an alleged fraud of over £1billion leading to the collapse of a large Russian bank. Jack appeared as sole counsel at an interlocutory stage dealing with a search order and related confidentiality requirements.
  • Saatchi v Gajjar: Acting as sole counsel for a former business partner of a well-known art dealer in wide ranging litigation concerning the ownership of a multi-million pound art storage warehouse, and claims for breach of directors’ duties.

  • AHAB v Saad (ongoing): Acting as junior counsel (with Tom Lowe KC) in one of the largest fraud cases ever litigated, involving a claim for around US$9bn, a trial lasting over a year and the disclosure of over 5 million documents. In addition to complex issues of fact, the case involved issues relating to tracing and asset recovery, trust and partnership law, attribution of knowledge, ex turpi causa, bona fide purchase, conflicts of law and the law of Saudi Arabia, Switzerland and Bahrain. Jack’s involvement included include cross examining an expert accountant in relation to a claim to trace over US$150m.
  • Re Sanguine: Acting as sole counsel in an appeal against the dismissal of a winding up petition against the respondent company. The appeal centred on the value of an underlying LLP (said to be worth over £1m by the Appellants) and it is now one of the leading cases on the meaning of guarantee provisions and whether the variation of those provisions took the relevant facility agreement outside the purview of the guaranteed obligations.
  • Re Integrated Control Solutions: Appearing as sole counsel in a five-day high court trial of competing unfair prejudice petitions.

Jack also has significant experience relating to commercial property involving a fraud or insolvency element:
