experience & expertise

Chris leads the award-winning Serjeants’ Inn Clinical Negligence and Healthcare Team.  He has been recognised as a leading clinical negligence practitioner for many, many years. Before the age of 30, Legal 500 included him in their “top 40 barristers under 40”. As a silk he has undertaken the most legally and technically complex cases for both top claimant and defence firms. He is a team-player, ensuring he works with his top-rank solicitors to get the best from their experts. He adopts a meticulous forensic approach. Through focussed questioning of specialists, he distils complex medical and scientific ideas into a straightforward presentation for the court. His empathetic approach ensures that clients are reassured, and understand their own cases and the legal team’s assessment of their merits.

His extensive experience has been recognised by his peers: he was appointed as co-chair of the Professional Negligence Bar Association’s Clinical Negligence weekend (2014-2018). He has been exposed to nearly every conceivable type of medical case, ranging from complex retinopathy of prematurity to high value cerebral palsy and brain damage cases (such as the Fieldfisher case in which a £9m award was secured for Rebecca Ling, whose heroism in the face of her profound disabilities was recognised when she carried the Olympic flame). He has extensive experience of fatal cases including recently acting for Irwin Mitchell in a £4 million settlement for the family of an investment banker who died after receiving sub-standard medical treatment.

Chris’s background in medical ethics cases and position as editor of the leading medical treatment text means he is well placed to handle the sensitive issues involved in mental health clinical negligence cases. He has acted in many high value claims involving catastrophic injuries following suicide attempts. Chris recently acted in a case involving an informal patient with a long history of mental illness, who was allowed to run away from hospital in a suicidal state, then jumped from a balcony sustaining permanent and catastrophic spinal cord injury, leaving him tetraplegic and wheelchair-bound.

Chris is adept at handling cases involving novel points of law such as XX v Whittington (surrogacy), and Toombes v Mitchell (wrongful life claim from disabled woman allegedly born as a result of negligent pre-conception advice given to her mother). Recently, Chris acted for the family in a case where premature delivery had left a ten year old child severely disabled, which was settled for £3.5 million.

Chris is recognised as one of the top claimant product liability silks. He authored the very well received “A personal (and selective) introduction to product liability law” for the Journal of Personal Injury Law (cited with approval in Michael Jones, Medical Negligence, 2018).  Throughout his career he has been involved in complex group actions, starting with the dental quantum group action Appleton v Garrett. He was also instructed in a number of million-pound class actions against various manufacturers arising out of difficulties patients have experienced with metal on metal hip implants and resurfacings.

He has unrivalled technical expertise in dealing with vast group actions as both junior and silk. He is exceptionally computer-savvy using his Excel skills to create impressive shortcuts for juniors and solicitors through substantial damages and disclosure exercises.

Chris spoke to APIL during lockdown on the use of technology in litigation.  He has led in-house and external talks on mediation.  He constantly looks to innovate and learn from other fields and professions: over the last 5 years, he has chaired a series of talks and conversations led by Nicola Hurdley, serving Detective Chief Inspector and Crisis Negotiator, on improving communication techniques by learning from internationally recognised tactics.

I wanted to be an astronaut. My earliest memories are of watching the Apollo moon buggies. I was devastated when I learnt aged eight that my colour-blindness meant my dreams of being an astronaut could not be fulfilled. That visual defect was obviously the only reason it was Tim Peake and not me hanging out with the Russians in orbit. I did settle on being a barrister a surprisingly short period of time after giving up on my space odyssey. The Bar was repeatedly mentioned to me as a career option. I liked to think it was because of my combination of skills in maths, science and the arts at school. I now realise it was probably because I never shut up and loved “drama” whether on stage, or in life more generally.

“All my cases entail human interest stories… People are at the core of the work.”

Spreadsheets are your friend. I should have invented Facebook and not been a barrister. As a kid for a time my only real friend was my Acorn Atom computer with its cassette tape program storage system. The publication of my Formula 1 racing game and Morse code decoder software should have given me the hint that there was money to be made in this new-fangled computer world. I love to bring the latest technologies into my preparation and presentation of cases with my latest best friends being my iPad Pro and my Apple pencil. Technology should be your friend in litigation.

It’s the humanity, stupid. However, for all my love of gadgets, what makes me so passionate about my work is its humanity. All my cases entail human interest stories: tragedies and follies, resilience and bravery. People are at the core of the work. Understanding the human relationships that underpin medical interactions is endlessly fascinating. It is also a privilege to work with solicitors, experts and clients as a team to understand complex medico-legal cases. The resilience and fortitude of injured clients and their families never ceases to amaze me – and put one’s own trivial woes into proper perspective.

There’s no such thing as a silly question. Asking highly specialist doctors and experts a series of simple questions about a technical topic is always revealing. The apparently stupid question often reveals either a central nugget of understanding or – as often – the ultimate limitations of scientific understanding of the human brain and body.

A bit of humility goes a long way. As we sit bewigged in our ivory chambers, we must always guard against over-confidence and the glib easy answer. The more I have learnt about litigation over the years (and specifically medico-legal litigation) the more I realise I don’t know. The work requires long hours. It is never easy but it is never boring. My pupil supervisor, Dame Nicola Davies DBE, was a highly gifted advocate. Yet despite her reputation as a “natural” and “instinctive” advocate, she instilled in me the key litigation mantra: “preparation, preparation, preparation.”


Educated at Ballymena Academy in Northern Ireland, Chris obtained a first class degree in Law from Cambridge University (Trinity Hall).
