Tess joined chambers in July 2026, having completed her pupillage under the supervision of Bill Evans and Kira Chana.

Tess defends in the Youth, Magistrates’, and Crown Court and is building a busy practice across the spectrum of criminal law. She is also a Grade 1 CPS Panel Advocate, prosecuting cases in the Crown Court.

She has undertaken additional training in advocacy for children in conflict with the law through ICCA. She is well placed to deal with the complex and often specialist issues arising in cases concerning those under the age of 18.

Before coming to the Bar, Tess accumulated almost 5 years’ experience in criminal defence. This included working as a senior crime paralegal and accredited police station representative at a busy criminal defence firm in central London.

Alongside a first-class degree in law, Tess was awarded for academic excellence in Health Law. Across two extended assignments, she explored the continued criminalisation of abortion, and common misconceptions surrounding women’s capacity to make decisions about their own treatment under the Mental Capacity Act 2005.

Tess volunteers to support prospective barristers in their advocacy and route to the Bar, including through Young Bar Mentoring and National Speed Mooting.

She received a full Bar Course Scholarship from Lincoln’s Inn and went on to achieve a distinction on the BPTC, before being called to the Bar in 2023.

Cases:

R v O (2026) – Defence counsel for sentence in a case involving multiple grave offences under the Sexual Offences Act 2003.

R v M (2026) – Defence counsel for sentence of causing grievous bodily harm with a kitchen knife at the Central Criminal Court, resulting in a suspended sentence.

R v O (2026) – Defending a Youth Court trial of assault occasioning actual bodily harm, within which a 17-year-old child had been filmed at the scene of a fight. Tess made submissions as to intention, joint enterprise, and causation resulting in an acquittal.

R v R (2026) – Defending a Youth Court sentence of a 16-year-old child relating to 9 offences, including possession of blades and dangerous driving. In line with current and updated guidance, Tess drafted a detailed sentencing note outlining the correct approach to sentence. The child avoided detention and received a Rehabilitation Order in the community.

R v I (2026) – Defending a Magistrates’ Court trial involving harassment of an ex-husband. Tess noted one charge failed to amount to a ‘course of conduct’, and the other was out of time under section 127 of the Magistrates’ Courts Act 1980. She resisted a prosecution application to amend the charges out of time, resulting in the crown offering no evidence.

R v L (2026) – Defending a Magistrates’ Court trial of assault occasioning actual bodily harm, possession of Class A drugs, and criminal damage. The defendant was acquitted of all charges following scrutiny of mobile phone and doorbell footage which purported to show the offences taking place.

R v S (2026) – Defending a Magistrates’ Court trial of a company charged with failing to identify the driver of a company vehicle. The District Judge was content that on the balance of probabilities, the Notice of Intended Prosecution had been responded to, despite no receipt having been retained.

R v H (2026) – Defending a Magistrates’ Court trial for possession of an offensive weapon. Cross-examination of the sole crown witness and submissions on insufficiency of the evidence resulted in the acquittal of the 70-year-old defendant.

R v E (2026) – Defending a successful Exceptional Hardship application made to avoid the mandatory 6-month disqualification from driving under the ‘totting up’ scheme.
