"A Rising Star” in the Court of Protection"

Legal 500 2021

Thomas is a popular common law practitioner who appears in court on a daily basis across the full range of Chambers’ practice areas.

The breadth of his practice has made him an adaptable and comfortable advocate. Thomas is ranked as a ‘Rising Star: Tier 1’ in the Legal 500.

He graduated first place on the Law and French programme at Cardiff University, was awarded the top first in the year for his undergraduate dissertation and won the university mooting competition. He studied for the BPTC at City Law School, for which he was awarded four awards. Prior to joining Chambers, he worked as a stagiaire at the European Court of Justice and as a research assistant at the Law Commission of England and Wales.

He has an entirely paperless practice and has experience of conducting court hearings and conferences remotely.

Outside of work, Thomas is learning Welsh and is a Trustee of the Lord Edmund Davies Legal Education Trust, a social mobility charity which encourages students from disadvantaged backgrounds to aspire to legal careers.


Thomas represents claimants and defendants in road traffic, employer’s liability, public liability and product liability claims. He has a particular interest in international personal injury claims including claims brought under the Montreal Convention, the Athens Convention and the Package Travel Regulations. He is regularly instructed to advise on liability, evidence and quantum in fast track and multi-track cases.

Thomas also acts in clinical negligence cases. In pupillage, Tom spent two months with the head of the clinical negligence team in Chambers, with whom he drafted advices and pleadings in complex clinical negligence matters including failure to diagnose and cosmetic surgery. Prior to joining 9 Gough Square, Tom taught tort law to undergraduates at Queen Mary, University of London.

Notable Civil cases

B v. QB [2020]

Thomas acted for the Claimant in an application brought by the Defendant to bar the Claimant from relying on his own medical evidence, due to a series of delays in putting Part 35 questions to the medical expert. The application was dismissed and costs awarded to the Claimant.

TY and FY v. T [2019]

Thomas successfully represented the Claimants in this fast track trial, despite low velocity evidence, and recovered two sets of fixed costs pursuant to section IIIA of CPR 45.

A v. SR [2018]

Thomas acted for the Defendant in this successful strike out application. The court accepted Thomas’ submissions that the claim was an abuse of the court’s process as the Claimant was seeking to re-litigate a previously litigated claim contrary to the principle of res judicata. This entitled the Defendant to full costs in circumstances where fixed costs would ordinarily have applied.

Thomas is ranked as a ‘Rising Star: Tier 1’ in the Legal 500 for Court of Protection and Community Care. He was recently shortlisted for the Young Family Barrister of the Year Award for his expertise in dealing with cases which overlap the jurisdictions of the Family Court and the Court of Protection. His nomination describes him as a ‘formidable force in cases where there is an interplay between the two jurisdictions’.

He accepts instructions from local authorities, health boards and NHS trusts, protected persons, the Office of the Public Guardian, deputies, attorneys and private individuals. He has appeared in disputes relating to residence, care, contact and medical treatment.

Thomas has a busy paper practice alongside his court work, advising and drafting on matters related to the Court of Protection. Most recently, he has advised on the following:

  • Whether a deprivation of liberty order made by the High Court of England and Wales was valid in a separate jurisdiction.
  • Whether restrictions on an inpatient at the Bethlem Adolescent Psychiatric Intensive Care Unit amounted to a deprivation of liberty.
  • Whether a maternal aunt, who was the main carer of the subject child, could consent to circumstances which amounted to a deprivation of his liberty.

Prior to joining Chambers, Thomas worked for the Law Commission on its review into the Deprivation of Liberty Safeguards. The UK Government responded to the Law Commission’s review by agreeing that the DOLS system should be replaced as a matter of urgency. The Mental Capacity (Amendment) Act 2019, replacing the DOLS with the LPS, received Royal Assent in May 2019.

In 2019, Thomas was seconded to the Welsh Government where he advised on the implementation of Mental Capacity (Amendment) Act 2019 in Wales. Tom principally advised on the legal accuracy of the new LPS Code of Practice.

Thomas acts for local authorities, parents and children’s guardians in all aspects of care, adoption and other public law family proceedings. He has appeared in cases of neglect, substance misuse, non-accidental injury and child abuse.

In his first year in Chambers, he was nominated for the ALC outstanding newcomer award for ‘the commitment he has shown to developing the law relating to children and the vulnerable, specifically in the field of the Deprivation of Liberty Safeguards’.

Thomas is frequently instructed in cases which overlap with his Court of Protection practice. He is particularly sought after in cases involving medical treatment decisions in respect of children or in cases with a care package which amounts to a deprivation of liberty.

Notable Family Law cases

He is a member of the Attorney General’s Junior Junior Panel and the Welsh Government’s Junior Barrister Public Law Panel. Prior to pupillage, Thomas was a stagiaire at the European Court of Justice to the UK Advocate General and later became a legal advisor within the European law department at an international law firm in Brussels.
