Jen has a varied practice which encompasses public, public procurement, employment, commercial litigation, and information law. She frequently appears in the High Court, County Court, Employment Tribunal, and First-tier and Upper Tribunal.

Jen’s focus on the intersection of public and commercial law underpins her specialisms in commercial litigation, commercial judicial review and procurement law. She often works with clients in the nascent stages of litigation to strategically prevent adverse decisions. She is available to work on an urgent basis.

Within her employment practice, Jen is experienced as sole counsel in multi-day trials. She is deeply familiar with the wide range of issues parties face in this area, from litigation on breach of fiduciary duties, to discrimination.

As sole counsel, Jen has substantial experience of handling cases which relate to breach of fiduciary duties, complex allegations of whistleblowing, all heads of discrimination under the Equality Act 2010, breach of contract, holiday pay, and unfair dismissal.

In addition to her trial experience, Jen is practiced in a wide range of interim matters that arise commercial employment litigation – from making and resisting anonymisation applications in the Tribunal, to costs limitation applications in the Court of Appeal.

Public Law and Human Rights

Jen advises and acts for both claimants and respondents in a wide range of public law challenges. She is particularly interested in the intersection of public and commercial law, and how public law can be utilised to work for businesses facing adverse regulatory decisions.

Jen’s experience in bringing and defending judicial review claims includes:

  • Led by James Goudie QC, representing two claimant local authorities in a claim against the Secretary of State in relation to a local government reorganisation. The claim is ongoing.
