Jack joined Monckton Chambers as a tenant in 2016 following successful completion of his pupillage. He practises across all Chambers’ specialisms with a particular focus on Competition and Regulatory Law, Public Law (UK and EU), and Sports Law. He is also developing experience in international trade and WTO law.

Before qualifying as a Barrister, Jack was a College Lecturer at Brasenose College (University of Oxford) where he taught Administrative Law and Constitutional Law. Jack has also undertaken a traineeship at the Court of Justice of the European Union with Judge Vajda (British Judge), and a six-month secondment in the Bank of England’s Legal Directorate’s EU Withdrawal Unit. With these experiences, Jack is well-placed to assist with a range of Brexit-related matters.

Jack graduated from the University of Oxford (Hertford College) in 2014 with a Distinction in the BCL masters in Law (ranked 2nd in the year). Before that he graduated from the University of Cambridge (St Catharine’s College) in 2012 with a First Class Degree in Law. Jack was awarded University prizes for coming top of the year in Administrative Law (Cambridge, 2011), Labour (Employment) Law (Cambridge, 2012), and Comparative Public Law (Oxford, 2014).

During pupillage, Jack sat with Rob Williams, Ben Lask and Laura Elizabeth John.

  • Competition and Regulatory Law

    Jack is currently instructed (with Alan Bates and Michael Armitage) to act for the defendant in the first “opt-out” class action competition proceedings brought under the new private damages regime introduced by the Consumer Rights Act 2015. More information is available here .

  • Public Law (UK and EU)

    Due to his academic and teaching background, Jack has experience and expertise beyond his date of Call in a range of public law matters (in both UK and EU legal systems). He has already been instructed in high profile public law litigation:

    • R (Miller and Dos Santos) v Secretary of State for Exiting the European Union [2017] [2017] UKSC 5  – Jack was junior counsel for one of the Interested Parties (Pigney and others: “The People’s Challenge”) in the Article 50 Brexit litigation at both Divisional Court and Supreme Court levels. The case concerned whether Parliamentary involvement was necessary to trigger any UK withdrawal from the EU or if mere use of executive power (under any subsisting prerogative power) was sufficient. More information is available here.
    • AI and XH v Secretary of State for the Home Department [2016] EWHC 1898 (Admin) – Jack was junior counsel for one of the Claimants (AI) at the Divisional Court level in his judicial review concerning whether the royal prerogative to  withdraw a British Citizen’s passport had been abrogated by the Terrorism Prevention and Investigation Measures Act 2011 or was lawfully exercised in any event.

    Whilst a stagiaire at the Court of Justice of European Union, Jack worked on cases including: Kadi II (the effect of European procedural rights), Pringle (the validity of the European Stability Mechanism), Abdulrahim (continuing interest to bring an action for annulment), and Inuit I (the definition of regulatory acts in Article 263 TFEU for the purposes of standing).

  • Sports Law

    Jack has advised and assisted on a range of sports matters, particularly in a football context. He has advised both clubs and private individuals in relation to settlement agreements, stay applications, strike out applications, arbitration proceedings and FA disciplinary proceedings concerning matters such as: agent fees, player transfers, contractual disputes and allegations of fraud and unlawful means conspiracy.

    Jack is currently assisting Michael Armitage who is instructed by a former employee of a major football club in High Court proceedings raising issues of unlawful means conspiracy and fraud.

    During pupillage, Jack assisted Paul Harris QC and Fiona Banks representing a Premiership football manager in respect of contractual disputes. He has recently assisted Paul Harris QC in preparation for FA disciplinary proceedings, and regards a private settlement agreement.

  • International Trade

    Since the EU Referendum outcome, Jack has experience of advising on international trade options and WTO law, with a particular focus on GATS and financial services post Brexit (including topics such as: FTAs under Article V GATS, dispute settlement mechanisms, GATS Schedules of Commitments, mutual recognition agreements under Article VII GATS, the prudential carve out in the Financial Services Annex to GATS, and the jurisdiction of the ECJ in relation to international agreements).
