Jen runs a commercial and public law disputes practice, especially focussing on employment & business protection, procurement & administrative challenges and, increasingly, disputes involving an international element.
Jen has been recognised in the legal directories since 2020, where she is described as “one to watch”, “exceptionally bright” and an “absolutely excellent barrister”.
As well as fitting into larger teams, Jen is experienced in representing clients as sole counsel in the Court of Appeal, High Court, EAT and the Tribunals. Recent cases include:
- Acting for the claimants in the largest UK procurement damages claim (£100m+) against the Gambling Commission’s procurement of the 10-year Fourth National Lottery Licence (led by Philip Moser KC and Ewan West).
- Assisting the Government of Antigua and Barbuda in defending proceedings challenging its acquisition and sale of the $120m superyacht Alfa Nero impacted by the US’s Russia sanctions programme (led by Paul Reichler and Richard Leiper KC).
- Defending and counter-claiming for the F1 Aston Martin Racing team against a multimillion pound High Court employment and shareholding dispute brought by its former Team Principal, Otmar Szafnauer (led by Daniel Stilitz KC).
Jen is experienced in fighting for clients in the High Court and Tribunal. She handles cases across the spectrum: from business protection and high-value contractual litigation, to whistleblowing and other statutory employment claims.
Jen is recognised in Chambers and Partners, where her clients describe her as having an “amazing… knowledge of the law” and “ability to absorb complex information quickly”, and being “client-friendly, hugely well-prepared and an outstanding advocate”.
Jen regularly handles high-value, multi-week trials as sole counsel, often involving complex whistleblowing or discrimination allegations. She successfully defended a multimillion-pound whistleblowing claim in Costagliola Di Fiore v Introhive Ltd, where she obtained the maximum costs awards available against the claimants (appeal ongoing). She represents the respondent in the forthcoming appeal in Matthews v CGI, in which the EAT will address the correct approach to the assessment of a dismissal without any procedure and causation in victimisation claims.
In the High Court, Jen is experienced in handling injunctive relief for clients, and in advising on and executing strategy in business protection cases (addressing restrictive covenants, team moves/unlawful conspiracy and the protection of confidential information). Jen is also adept handling contractual disputes, particularly those involving complex facts or points of law. She recently represented the F1 Aston Martin Racing team’s defence and counter claim to the multi-million pound litigation brought by its former Team Principal in relation to his resignation, bonus and shares (led by Daniel Stilitz KC).
Jen also has deep experience in employment group litigation, acting for the claimants in the high-value and potentially industry-re-shaping equal pay litigation against Tesco (led by Sean Jones KC). The litigation has already redefined the law on equal pay in the EAT and CJEU on: the single source of employment; the burden of proof; job evaluation studies; and the correct approach to disclosure.
Other examples of Jen’s recent work include:
- Costagliola Di Fiore & Qadri v Introhive Ltd – successfully acted as sole counsel for the tech-sector respondent in a multiweek multi-million-pound whistleblowing and unfair dismissal trial; secured the maximum costs orders against both claimants in the ET; Jen continues to defend the respondent in the EAT in an appeal on the correct approach to rejecting an application for a witness order mid-trial.
- Guy Carpenter v Howden Tiger – assisted the reinsurance brokerage sector-claimants (led by Dan Oudkerk KC and Amy Rogers) in one of the largest High Court claims ever brought against former employees and competitors for unlawful means conspiracy and breach of restrictive covenants, following a team move raid on its business (48 employees including its Europe CEO, across several European offices).
- Confidential High Court injunctive matter – restrictive covenants [settled] – acted for a tech company to enforce non-competes in a senior engineer’s employment contract (led by Amy Rogers).
- Confidential discrimination & equal pay matter [settled] – acted for a female senior executive in an investment bank in relation to her claim for sex discrimination and equal pay.
- Kabzinski v Vistajet International Ltd – successfully defended harassment and direct race discrimination allegations against a private jet company, proving that otherwise strong language was not unwanted or on the grounds of race in proper context. Acting for respondent in EAT appeal to the decision, initially as to the correct approach to an extension of time.
- Matthews v CGI Ltd – as sole counsel, successfully defended a professional services-sector respondent against whistleblowing, discrimination and unfair dismissal claims. Continues to defend the forthcoming EAT appeal, on the correct approach to dismissals without a procedure, victimisation causation and extensions of time.
- Van Mackelenbergh v Maritime Transport Ltd – as sole counsel, successfully defended a summary judgment application in the High Court in a high-value contractual claim from a former COO.
- Szafnauer v Aston Martin Racing Ltd – acted for the F1 AMR team in its High Court defence of a multimillion-pound claim alleging constructive dismissal and shareholding claim, and prosecuting its contractual counterclaim against its former Team Principal (led by Daniel Stilitz KC).
- K Element & others v Tesco – acting for the Leigh Day claimants in their group litigation equal pay claims against Tesco (total estimated to be worth to be potentially into hundreds of millions of pounds) which, if successful will reshape the industrial structure for the supermarket industry (led by Sean Jones KC and Andrew Blake).
Procurement & Subsidy Control
Jen has a busy procurement practice. She is experienced in procurement litigation, from advising at the preliminary stages, to Applications to Lift and wider litigation strategy. She acts as sole counsel, as well as within larger teams.
Jen represents the claimants in the high-profile and largest ever UK procurement damages claim (>£100m) in IGT v Gambling Commission, a challenge to the award of the 10-year Fourth National Lottery Licence, that has clarified the law on standing to claim in relation to non-bidders (led by Philip Moser KC and Ewan West).
As well as acting for claimants and defendants, Jen is experienced with representing the successful bidder Interested Party seeking to retain the contract (MLS (Overseas) Ltd v MoD).
Within the new Subsidy Control regime, Jen is already experienced advising clients on the assessment of subsidies and potential subsidies, including advising on a £100m transport and housing redevelopment scheme as sole counsel.
Jen’s recent work includes:
- IGT v Gambling Commission – acting for the claimants (led by Philip Moser KC and Ewan West) in the £100m+ challenge brought by sub-contractors to an unsuccessful tenderer against the Gambling Commission’s procurement of the Fourth National Lottery Licence under the CCR 2016. The high-profile litigation included a contested Application to Lift, expedited proceedings, and is legally significant as it clarifies the law on the standing of non-tenderers.
- Confidential challenge under the PCR 2015 [settled] – as sole counsel, defending a proposed challenge to an NHS procurement of electronic record system (contract value £80m), to successfully avoiding issue of the claim.

Jen has experience advising and acting for clients in litigation spanning chambers’ diverse commercial disputes work – from business protection to fraud. She has appeared in both the High Court and County Court. She is particularly well placed to assist with commercial matters involving elements of public or employment law, but her practice extends well beyond this.

The other concerned ten allegations against multiple individuals of misfeasance, discrimination and failures to follow policy in recruitment decisions and governance of whistleblowing complaints.
Jen is also one of a small team the barristers appointed by the Football Association (led by Clive Sheldon KC) in the high-profile Independent Review into non-recent child sexual abuse allegations in football.
