Deka Chambers
3-5 Norwich Street

Work Department

Court of Protection


Thomas is a busy 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.


Since joining Chambers, Thomas has developed a busy Court of Protection practice, particularly in cases involving the health and welfare jurisdiction. In Thomas’ 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”.

In his second year in Chambers, Thomas was ranked as a ‘Rising Star: Tier 1’ in the Legal 500 for Court of Protection and Community Care. He was also shortlisted for the FLA Young 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, the Official Solicitor, the Office of the Public Guardian, deputies, attorneys and private individuals. He has appeared in s. 16 cases, s. 21A cases and a series of deprivation of liberty order applications under the inherent jurisdiction of the High Court. Thomas has recently been instructed to advise on the application of a Deprivation of Liberty order made by the High Court of England and Wales in a separate jurisdiction. He has also advised on whether restrictions placed on an inpatient at the Bethlem Adolescent Psychiatric Intensive Care Unit amount to a deprivation for the purposes of article 5 of the ECHR.

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. Thomas principally provided advice to the Welsh Ministers on the legal accuracy of the new LPS Code of Practice.

Thomas is a committee member of the Court of Protection Bar Association.
