Stuart McKechnie QC

Call: 1997 Silk: 2018

"Absolutely masterful: he provides clear, detailed advice on very high-value claims, and is very hard-working and thorough."

Chambers & Partners Personal Injury 2021

Stuart specialises in the highest value catastrophic injury claims involving complex issues and large numbers of experts.

He works for many of the leading personal injury and clinical negligence solicitor firms in the country and almost all of his practice is at the High Court. He is a past winner of ‘Personal Injury/Clinical Negligence Junior of the Year’ at the Chambers & Partners Bar Awards (2017) and Personal Injury Barrister of the Year at the Personal Injury Awards (2011).

Over the last 3-4 years Stuart recovered damages with a combined capital value in excess of £140,000,000 (one hundred and forty million) on behalf of Claimants. In JDF (a Child) v Hampshire County Council, he settled what is thought to be the highest Personal Injury award ever made/approved by a Court in the UK, the equivalent of £28 million capitalised. This case was covered across the national media. He is also currently instructed on what is likely to be one the largest personal injury claims ever made in Northern Ireland.

Stuart is one of only three Barrister members of the working party responsible for the Judicial College Guidelines for the Assessment of General Damages in Personal Injury Cases. He is the General Editor of the APIL Guide To Catastrophic Injury Claims (being the definitive practitioner guide to running high-value personal injury and clinical negligence actions).


Stuart has extensive experience across the full spectrum of catastrophic injury claims, including severe traumatic brain injury, spinal cord injury, brachial plexus injury, amputations and poly-trauma. He acts only for Claimants. Stuart regularly appears in the High Court and spends much of his time in conference with experts, drafting complex Schedules of Loss and representing Claimants at Joint Settlement Meetings. His role as General Editor of the APIL Guide To Catastrophic Injury Claims places him at the forefront of work within this field, meaning he is frequently instructed on the very highest value cases.

Notable Personal Injury cases

£7.2 million settlement for father of 2 who sustained severe orthopaedic injuries (lower and upper limb) in a RTA. One of the highest known settlements for poly-trauma without amputation or spinal cord injury.

Millar v. Oliver (2018-ongoing)

Instructed to conduct claim in Northern Ireland on behalf of businessman and elite athlete who has been rendered paraplegic in RTA. Covered across national media in Ireland. Likely to be one of the biggest personal injury claims ever made in Northern Ireland.

R v Gardiner (2021)

7 figure settlement for Claimant whose dominant arm was ripped off when struck by Defendant driver who lost control of his vehicle and left the road. The Claimant’s partner was killed instantly in the accident and she also suffered very serious PTSD. Case covered across the national media.

S v. Kepak Group (2019)

£4.75 million settlement for 37 year old man who suffered extensive lower limb injuries in a workplace accident resulting in a transfemoral amputation and leading to osseo-integration surgery in Australia. One of the highest known amputation awards in UK.

JWF [A Protected Party] v YWC (2018)

Lump sum settlement of £1,850,000 plus PPOs for care, case management and therapeutic needs for retired GP who suffered a severe traumatic brain injury and multiple orthopaedic injuries in RTA. Settlement approved at High Court.

XXP v. Metodiev (2018)

£10,000,000 lump sum settlement for catastrophically brain damaged student. 95:5% split liability. Lump sum settlement required because there was no reasonable security for a PPO. Settlement approved at High Court.

T v. D (2018)

£5,000,000 lump sum settlement for 54 year old man who sustained below knee amputation and brachial plexus injuries in a motorcycle accident.

Peters v. MOD (2017)

Claim against MOD on behalf of a civilian forensic scientist who was badly injured in an explosion whilst working in a MOD laboratory in Kandahar, Afghanistan in 2011. Case covered across national media. Details of settlement confidential.

JDF v Hampshire County Council (2017)

Claim on behalf of catastrophically brain damaged child injured in a RTA. Thought to be the highest ever personal injury damages award made or approved by a Court, with lump sum of £9,113,074 combined with PPOs for care & case management. The settlement had a capitalised equivalent value of £28 million. Stuart conducted the vast majority of the case as junior counsel without a leader but was led at the JSM by Frank Burton QC in his last case at the Bar before retirement.

Notable Clinical Negligence cases

IXM v Norfolk & Norwich University Hospitals NHS Trust (2017-onwards)

Catastrophic claim arising from birth injuries leading to severe brain injury, hypothalamic damage, intractable epilepsy and 24/7 care. The brain injury manifests via severe learning difficulties and highly challenging behavioural difficulties. This, combined with the daily seizures, means that the infant Claimant has hugely complex care needs. The case is listed for trial in early 2022 and will be worth a substantial 8 figure sum.

ABC v. Epsom & St Hellier Hospital NHS Trust (2019)

£3.7 million lump sum plus PPOs (£42,500-£128,000) for 19 year old young lady who suffered a period of severe asphyxiation at birth causing hypoxic brain injury and the development of a mild form of dystonic cerebral palsy. Settlement approved at High Court.

EXP v. Barker (2019)

Multi-million pound settlement for member of the judiciary who suffered a catastrophic aneurysm bleed requiring lifesaving surgery and resulting in devastating neurological and neuropsychiatric injuries. Stuart dealt with the quantum of the claim in silk having previously been led (as a junior) by Grahame Aldous QC at the successful trial on liability [2015] EWHC 1289 (QB) and the Defendant’s unsuccessful appeal to the Court of Appeal [2017] EWCA Civ 63. This case is now a leading authority on the duties of expert witnesses and conflict of interest.

Powell v North Bristol NHS Trust (2015)

Successful 5 day clinical negligence trial on behalf of Claimant. The Defendant’s case was reliant on the expert evidence of a world renowned shoulder expert. Following detailed cross examination by Stuart at trial, the judge (HHJ Denyer QC) rejected this evidence as flawed and illogical.

T v Walsall Hospital NHS Trust (2015)

Catastrophic clinical negligence claim arising from negligent treatment of 7 year old boy at Walsall Manor Hospital leading to severe cerebral ischaemia. The Claimant lived with his family in the Channel Islands and the case therefore involved complex quantum issues involving care, loss of earnings, curatorship and indexation. The claim settled almost 9 years post incident for a combined lump sum and PPO package worth over £11.5 million. Stuart was led by John Foy QC.
