Jack joined Cornerstone Barristers as a tenant in April 2022.

Jack previously completed his 12-month pupillage under the supervision of Dr Ashley Bowes, Andrew Lane, and Edward Grant. He worked on various matters in a range of areas including Public Law & Judicial Review, Planning & Environmental Law, Housing Law and Licensing Law.


Jack previously completed his 12-month pupillage under the supervision of Dr Ashley Bowes, Andrew Lane, and Edward Grant.

During his second six, Jack gained the following experience:
• Appeared in the County Court and Magistrates' Court in the context of small claims trials, possession hearings, access injunctions, closure orders and various other civil applications.

• Advised (both jointly and on his own) on planning matters, including for a local campaign group seeking to resist an application for planning permission.

• Represented a public objector in an application to renew a sexual entertainment venue licence at a Council sub-committee meeting.

During pupillage, he also worked on various matters for his supervisors and other members of Chambers.

With Dr Ashley Bowes, Jack built awareness of the specific challenges facing developers, local authorities, landowners, and residents' groups throughout the planning process. He engaged with many aspects of the development and use of land, including planning, property, public rights of way, and local government law, by:

• Drafting pre-action protocol response letters, Statements of Facts and Grounds, Summary Grounds of Resistance, and skeleton arguments associated with judicial review challenges in the Planning Court, including in relation to public rights of way, habitats and environmental impact assessments.

• Drafting advice on matters engaging issues relating to highways, the interpretation and legality of planning conditions, environmental regulation, compulsory purchase, adverse possession and boundary disputes.

• Assisting with the preparation of a party's submissions in the DCO process for the major infrastructure project of a proposed twin reactor nuclear power station at Sizewell C.

With Andrew Lane, Jack gained experience of a range of matters relating to housing, homelessness and allocations, and licensing, and he observed a wide range of proceedings from housing possession trials to appellate advocacy in the higher courts. His experience included:

• Drafting a skeleton argument for the Court of Appeal, which considered the proper approach to retrospective compliance with the public sector equality duty in the context of possession proceedings.

• Drafting advice on the legality of a local housing authority's proposed amendment to its allocation scheme.

• Drafting a skeleton argument for a homelessness appeal under section 204 Housing Act 1996.

With Edward Grant, Jack developed his understanding of planning law, including in an inquiry and enforcement context, through:

• Drafting advice on a range of planning and environmental matters, including on emerging issues relating to Habitats Regulations Assessments relating to phosphates and nutrient neutrality.

• Drafting skeleton arguments, including in relation to the Community Infrastructure Levy and Assets of Community Value.

• Assisting with research and preparation in relation to several planning inquiries.

Professional background

Jack has previously acquired both public and private sector legal and policy experience.

Before pupillage, Jack worked as a researcher for a public law academic on a monograph exploring the constitutional relationship between central and local government, and as lead paralegal for government decision-making at the Infected Blood Inquiry.

During his legal studies, Jack was a legal volunteer in Islington Law Centre's housing team, where he supported a solicitor's advice clinics. He also represented school pupils in school exclusion hearings. During the BPTC, Jack won first prize in a national planning and environmental law judicial review mooting competition organised by another Chambers.

Jack was selected as Hanover Communications' inaugural Mackay Award winner in 2016. He spent five weeks in Washington, D.C. during the presidential election and produced a report considering how electoral authorities might adapt to the latest innovations in political campaigning.

Jack worked within Hanover's government and public affairs team advising various multi-national clients on political, regulatory, legislative, and reputational issues, including on major infrastructure, environmental, and public service outsourcing matters. He maintains an interest in regulatory and governance issues: his recent article proposing reform of UEFA's Financial Fair Play Regulations won first prize in the Association of Regulatory and Disciplinary Lawyers' Marion Simmons QC essay competition (2020).


Jack read for a B.A. (Hons) in History (First Class), and a Master's in British and European History (Distinction) at Magdalen College, Oxford. As an undergraduate, he was awarded the Ewen Green Memorial Prize and an Academic Demyship. Jack completed the GDL and BPTC at City Law School and was called to the Bar in 2019 by the Inner Temple having received a Major Scholarship (GDL), an Exhibition Award and a Duke of Edinburgh Award (BPTC).
