Jen’s broad practice spans procurement, public, employment, commercial and information law.

Jen is experienced as an advocate in multi-day trials in the Employment Tribunal, across the spectrum of chambers’ employment law work. Within public law, Jen’s interest in the intersection of public and commercial law underpins her focus on commercial judicial review and procurement law. She acts both led and as sole Counsel in the High Court, and advises on strategy and merits in complex challenges.




Jen practises across the full spectrum of employment law in the Tribunals and High Court. Her recent work includes claims brought by both claimants and respondents for whistleblowing, breach of contract, unfair dismissal and claims under the Equality Act 2010.

Jen also has experience assisting on urgent and complex matters, such as:

  • whether the ET has territorial jurisdiction over a claim, in Ravisy v Simmons & Simmons LLP (assisting Daniel Stilitz QC, during pupillage);
  • in injunctive relief in industrial action and team move cases (assisting Jane McCafferty, during pupillage); and
  • researching the influence of public law principles on employment law, in relation to contractual disciplinary procedures (assisting John Cavanagh QC, during pupillage).

In addition to her core practice, Jen is available to provide witness familiarisation sessions. Participants have described the session as “invaluable”.


Jen’s experience positions her to advise and act in relation to matters as sole or junior counsel, depending on the matter at hand. Recent instructions include:

  • Acting for the interested party, the successful tenderer in a procurement for a contract worth £385m, in MLS (Overseas) Ltd v The Secretary of State for Defence (2017) EWHC 3389 (TCC). The challenge was brought to the contract award by an unsuccessful tenderer, under the Defence and Security Public Contracts Regulations 2011.
  • Advising on and settling the particulars of claim under the Public Contracts Regulations 2015 and statement of facts and grounds in a judicial review for a challenge to the procurement of a contract worth £42m in the healthcare sector, led by James Goudie QC. These threatened challenges ultimately led to the reopening of negotiations with the contracting authority.
  • Delivering external assurance for the procurement process for a high profile contract worth £490m for a central government department, under the Public Contracts Regulations 2015. The procurement has stood, unchallenged.

Public Law

Jen gained extensive experience in bringing and defending judicial review proceedings and advising on public law during pupillage, with supervisor Jonathan Moffett QC. This included the challenge to the consultation for the Sheffield Combined Authority in Derbyshire CC v Barnsley, Doncaster, Rotherham and Sheffield Combined Authority [2016] EWHC 3355 (Admin).

Since commencing practice, she has acted for the claimant, a victim of trafficking, in a judicial review the Legal Aid Agency’s refusal to waive the statutory charge for legal aid in R (Tirkey) v Director of Legal Aid Casework [2017] EWHC 3403 (Admin), QBD (led by Peter Oldham QC and Zac Sammour). Jen has also advised on the merits of a challenge to the Data Protection Act 2018, with Jason Coppel QC.

Given her broad practice, Jen is particularly interested in the intersection of public and commercial law, and how public law can be utilised to work for business.

Jen is currently one of a small team of barristers instructed on the Independent Review into Child Sex Abuse Allegations in Football, led by Clive Sheldon QC. Other examples of recent work include:

  • advising a local authority on the claw-back of pupil premiums from academies when a pupil leaves an academy school;
  • advising a local authority on the powers of a local authority to hold a referendum (assisting Peter Oldham QC, during pupillage); and
  • advising a public authority on the legality of using the cloud to store data under the Computer Misuse Act 1990 (assisting Julian Blake).


Jen has experience across chambers’ diverse commercial dispute resolution work, from business protection to fraud. She is particularly well placed to assist with commercial matters with elements of public or employment law.

Her recent un-led work includes:

  • advising on a claim worth £120,000, where a Port Authority had seized and destroyed a shipment of goods;
  • acting for the University of Roehampton and University of Nottingham in strike out and relief from sanctions applications of contractual claims;
  • acting for Deliveroo in multiple contractual claims; and
  • advising on a civil fraud claim (assisting Julian Wilson during pupillage).

Information Law

Jen is regularly instructed by the Information Commissioner on information law matters. She brings this experience to her work on information and data protection matters for private clients.

Recent instructions include:

  • Acting for the Information Commissioner in the appeal of a Monetary Penalty Notice of £300,000 in relation to automated marketing calls in breach of Privacy and Electronic Communications Regulations 2003 (Holmes Financial Solutions v Information Commissioner);
  • Settling statements of case in various claims under Privacy and Electronic Communications Regulations 2003; and
