Experience & Expertise

Cases & Work of note

From 2015 – 2019, Jamie was junior Counsel to the Inquest in the fresh inquests into the deaths of army trainees at Deepcut Barracks in 1995 and 2001. In his own right, Jamie has appeared in many inquests acting on behalf of families, NHS Trusts, individual clinicians, and other Interested Persons, often appearing alongside very experienced barristers including silks and frequently dealing with issues of Article 2, neglect, and PFD reports.

In clinical negligence, Jamie acts on behalf of both Claimants and Defendants in a wide array of cases, including high value catastrophic injury claims in the High Court and cases involving complex expert evidence.

In the Court of Protection, Jamie accepts instructions in both health and welfare matters and those concerning property and financial affairs, acting on behalf of the OS, OPG, local authorities, NHS Trusts and individual family members caught up in what are often emotionally involved cases.

Jamie is keen to develop a broad practice and his experience ranges from judicial review actions in the High Court and representing doctors in regulatory proceedings, to defending English Heritage in the County Court against a claim brought by a druid.


Jamie co-authored chapters fifteen: Withdrawal and Withholding of Treatment, sixteen: The Right to Die? and seventeen: Treating Suicidal Patients in the fourth edition of the book Medical Treatment: Decisions and the Law, edited by Christopher Johnston KC and Sophia Roper KC and written by 27 members of Serjeants’ Inn.

Jamie also co-authored the third edition of Medical Treatment: Decisions and the Law.

Jamie writes for the UK Inquests Law Blog and the UK Police Law Blog, and has drafted headnotes for the Inquest Law Reports.

Seeing a case from a Judge’s point of view was the most valuable experience I gained from the Deepcut Inquests. Most Judges or Coroners – we hope, all of them – come to cases with an open mind and are genuinely dedicated to considering the evidence impartially. It’s so important to shake off any preconceptions or assumptions about a case, and really think about how the evidence will appear to a Judge, tribunal or Coroner looking at a case with fresh eyes.

Whenever I see another barrister performing brilliantly in court, it’s almost always because of how well prepared they are. You can’t succeed unless you know the case inside out. But a barrister isn’t any use to anyone unless they can appreciate what evidence really matters: the challenge is to make out the melody amid all the background noise, and then persuade the Judge to hear the same tune as you.

You learn every day in this job, about the law, about medicine, but also about tactics and strategy in all types of cases. The more cases I take, the more I realise how much the final outcome can be determined by decisions made by the parties really early on. I’m very happy to be involved in the early stages of any case, and I keep the ultimate outcome in mind when making all decisions.

“The law in our practice areas is constantly moving and outcomes are so fact-sensitive that every case needs a customised approach. You’ve got to be versatile.”

The best advocates have more than one setting. I would never want to have a reputation as a particular type of advocate. I’d want to be thought of as a barrister who can adjust their style to what is actually going to help their client.

Empathy is central to success. I try not to make assumptions about how people feel about court proceedings: they can often surprise you. You can’t achieve what your client wants unless you understand what that really is. And sometimes, listening to other parties and appreciating what motivates them can be the key to reaching your own client’s goals.
