Experience & Expertise
Jon specialises in clinical negligence and healthcare, professional discipline, inquests and inquiries, police and employment law.
Jon has a complex and high value clinical negligence work load. On the defence side he has been instructed for over 20 years by all the major medical and dental defence organisations, by the NHS in Wales, and by the NHSLA since its foundation. He is also routinely instructed on behalf of claimants in high value and medically complex cases. Recommended by both the leading legal directories in this field, he is described by the current edition of the Legal 500 as “a thoughtful, steady hand, who instils confidence and has good judgement.“
Jon is also known for his professional discipline expertise, having been instructed in professional disciplinary cases since 1997. He has regularly appeared in the General Medical Council and General Dental Council since that time. He continues to be instructed by all of the medical and dental defence organisations in such cases. He has been instructed in a number of cases in which he has represented doctors in internal disciplinary proceedings, often against a background of actual or potential proceedings against the practitioner by his or her regulator. Again he is ranked as a leading barrister in this field by both the legal directories, with the current edition of Chambers & Partners noting that “he is very sharp, bright and takes a forensic approach, which makes him extremely good in complex clinical cases”.
He has appeared in many medical inquests. He has maintained an interest in employment law, especially in cases in which there is both an employment and a professional discipline element, and his experience of employment law extends into the police field, in which he has appeared in many discrimination cases. He has a particular and longstanding expertise in police pensions cases.
cases & work of note
Jon’s recent clinical negligence cases have included:
EPX v Milton Keynes General Hospital NHS Foundation Trust
Jon represented the Claimant who had sustained brain damage in the neonatal period due to a failure promptly to treat a Group B streptococcus infection. Liability was admitted at an early stage after issue of proceedings but quantum proved more difficult. In January 2016 however settlement was approved on favourable terms.
Willis v Stern
Jon represented the defendant GP in this case which came to trial in June 2015. The claimant alleged that the GP had negligently failed to refer him for a specialist opinion when he was presenting with what proved to be a cervical myelopathy. This had led, on his case, to a 2-year delay in diagnosis and treatment of his condition and to his developing a grossly debilitating global pain syndrome. £1.9m was claimed. The defendant was successful on both breach of duty and causation issues, in that the pain syndrome (although genuine) was not found to have been caused by the delay in diagnosis and treatment of the cervical myelopathy.
Jones v Abertawe Bro Morgannwg University Local Health Board
This claimant in this case had undergone emergency abdominal surgery for a suspected appendicectomy, but histology following surgery showed that she had been suffering from a diverticulitis which could have been treated by antibiotics. The claimant alleged that a CT scan ought to have been carried out preoperatively which would have made the correct diagnosis, alternatively that she ought to have been told of the option of investigation by CT scan. The alternative case raised a legal issue as to the application of Montgomery v Lanarkshire Health Board. Jon represented the successful defendant at trial.
Jon’s recent professional discipline caseload has included:
General Dental Council v Kirschner:
This case involved allegations inter alia of dishonest claims under the NHS dental contract. Dishonesty was found proved in part by Professional Conduct Committee of the GDC and a suspension of 12 months was imposed. The findings of dishonesty were overturned on appeal to the High Court (Mostyn J) in May 2015. There was detailed consideration by the court of the correct legal test for dishonesty in disciplinary proceedings, of significance to all regulated professionals. The Ghosh test for dishonesty was affirmed, with reluctance, by the judge. When quashing the findings of dishonesty the judge agreed with Jon’s description of the findings of the PCC as “internally inconsistent” and “incoherent”. The case was remitted to PCC for reconsideration of sanction on other matters and a reprimand was imposed.
A Health Board v X:
These were complex disciplinary proceedings relating to a consultant surgeon. Concerns were raised about mortality rates and he was suspended amid national publicity. Jon represented him in GMC proceedings in which deficient professional performance was alleged and in complex internal disciplinary proceedings involving a detailed analysis of his management of 17 patient cases.
General Dental Council v X:
Jon represented a dentist with a high media profile. He had performed extensive crownwork, in part for cosmetic reasons, and the treatment was unsuccessful. It was alleged that the treatment was inappropriate and that the dentist had persuaded the patient to undergo expensive treatment which he knew was not suitable for her and that he therefore was dishonest. The allegations of dishonesty were successfully defended. Although the Professional Conduct Committee were critical of the treatment provided, the dentist’s fitness to practice was found not to be impaired.
Jon has recently represented several doctors required to give evidence by deposition in England in connection with product liability proceedings ongoing in the United States.
Jon is recommended by both The Legal 500 and Chambers & Partners for clinical negligence and professional discipline and regulatory law.

When I started in chambers I did the full range of common law work – everything from crime to landlord and tenant, consumer credit to family law. With hindsight this was an excellent foundation for the specialist work which followed, and I have always tried to retain diversity in my practice, to be adaptable in accepting instructions in areas related, but not necessarily central, to my core areas of practice, and to appreciate the overlap between those areas, such as professional discipline and employment law and the potential implications of one set of proceedings for another.
Not every area of practice provides the same opportunity for advocacy, in particular oral advocacy, but expertise in advocacy is critical in most areas of practice at one time or another, and advocacy is a skill which needs constantly to be practised. I have been heavily involved in professional discipline work for about 20 years and the regular experience of cross-examination of factual and expert witnesses in that field has been invaluable on the occasions on which such questioning has been required in clinical negligence or other trials.
I believe that the experience that I have had in acting for one side to a type of dispute has made me a better advocate when acting for the other.
One of the strengths of an independent advocate is perspective, the experience of having seen disputes from different, and often opposing, angles. A clinical negligence dispute is of the utmost importance to the injured claimant and those who care for him or her, who are likely to have much invested in it emotionally as well as financially; so too is it important to the clinician accused of causing injury by negligent care, whose confidence may be shaken to the core by a single case and who may be devastated by the suffering of the claimant. I believe that the experience that I have had in acting for one side to a type of dispute has made me a better advocate when acting for the other.
I think that the most important attribute of an advocate is clarity. Our job is to listen, analyse, assess, explain and ultimately to persuade, but you can’t persuade if you are not clear.
