Instructing Jonathan Bertram

For more information please contact our clerks by calling +44 (0)20 7242 3555.

Jonathan Bertram primarily specialises in the fields of professional (principally clinical) negligence, serious personal injury and product liability claims, though he has always maintained a common law practice and he continues to undertake various commercial and consumer law cases.

He has been instructed in several major group actions for Claimants in the product liability field including the Pinnacle Hip implant GLO which proceeded to a 4 month trial in 2017/18 (Gee v Depuy International Limited [2018] EWHC 1208 QB); various other metal-on-metal hip group actions; the SUI vaginal mesh litigation; the Oculentis lens litigation; the HPT litigation (acting pro bono for the Claimants, Wilson v Bayer Pharma AG et al [2023] EWHC 1282 QB); the Astra Zeneca Covid 19 vaccine litigation and the Covid healthcare works claims litigation.

His clinical negligence practice focuses on high value, complex claims, involving major, life changing injuries. He practices more widely across the personal injury field and he has particular expertise in chronic pain, subtle brain injury and spinal injury claims and the challenges that are made to them. He is also a keen cyclist and is frequently instructed in cycling related claims.

He undertakes professional negligence work beyond the clinical field and is particularly experienced with ‘legal’ negligence claims arising from failed litigation as well as claims made involving the work of financial professionals.

Legal Expertise

Clinical Negligence

Jonathan has been repeatedly rated by Chambers & Partners and the Legal 500 as a leading junior in the specialist field of clinical negligence.

He has been instructed in cases concerning birth injuries, spinal injuries, brain injuries, amputations, fatal injuries, late diagnosis of cancer, liver disease, kidney disease and other similar conditions. He has litigated many cases concerning orthopaedic procedures (spinal, shoulders, knees, ankles, wrists, and hips) and negligently performed bariatric and other similar weight loss/reduction procedure claims. He has successfully settled secondary victim claims arising from negligently medical treatment.

He has successfully pursued claims advanced on the basis of systemic failures by Trusts that have then led to injuries to patients, e.g. by failing to adequately staff maternity units.

He has litigated claims against dentists, optometrists and ophthalmologists.

Inquests & Inquiries

Jonathan is frequently instructed in ‘difficult’ cases where the outcome of the inquest is thought to be likely to make a material difference to whether or not a claim can be successfully pursued.

His recent medical inquests include cases concerning the management of patients in A&E departments, treatment that has gone ‘wrong’ during routine procedures such as cholecystectomies, concerns over the prioritisation of resources in cases of gravely ill children, cases where GPs have declined to refer patients for treatment who have subsequently died, cases where sepsis has not been diagnosed in a timely manner and cases where frail people have been inadequately assessed prior to or during their admission to care homes or hospitals.

He has dealt with numerous Article 2 inquests, particularly those concerning mental health cases, but also more widely such as acting for a housing association in an inquest concerning the death of a tenant who fell from her balcony.

He has also been involved in inquests away from ‘medical’ topics, for example, he has acted for interested parties in fire deaths and industrial workplace related fatalities.

Notable Inquests & Inquiries cases

Acting for a housing association in an inquest concerning the murder of a resident.

MK (2023)

Article 2 - Acting for a housing association concerning a death by falling from a balcony in a block of flats.

JA (2022)

In this inquest into the tragic death of a “brilliant” young man, the coroner confirmed that he died from natural causes, but his death could have been avoided had his cardiac abnormalities been identified and treated. The Coroner found that there were missed opportunities to make an inpatient referral for an echocardiogram, which would have revealed the cardiac abnormality and led to successful treatment for his rare heart condition. Had these steps been taken then JA would not have suffered his serious deterioration on 8 June 2022 and he would not have passed away on 24 June at just 22 years of age. Jonathan represented JA’s family at the Inquest earlier this month, having been instructed by Mala Patel at Hugh James. Johnny was a talented history student and musician, and his tragic death and the inquest have been widely reported in the national press.

AR (dcd) (2019)

1 day inquest concerning death in care home. Complicated medical causation issues. Claim subsequently settled.

5 day jury inquest into mental health death. Substantial failings found by jury. Claim subsequently settled.

Regulatory & Professional Discipline

Jonathan has a growing practice within the healthcare disciplinary field. He has represented doctors before the G.M.C. and he is keen to continue to develop this aspect of his practice in the future.


Jonathan is instructed in a broad range of commercial disputes, including sale of goods, insurance, consumer contract disputes, guarantee claims, agency claims, claims in professional negligence, and general contractual litigation.

In recent years his professional negligence practice has increased significantly and he has been regularly instructed in cases concerning allegations over the conduct of litigation by solicitors and other legal professionals. He has also conducted cases concerning architects, surveyors and medical professionals.

Jonathan has advised in a number of disputes concerning financial products; primarily in relation to interest rate swap claims, and mortgage mis-selling claims.

Personal Injury

Jonathan only takes instructions in multi-track personal injury claims. His recent practice has focussed on substantial injuries, which often have a long term or life changing impact upon the injured person. He has significant experience of dealing with chronic pain and subtle brain injury claims and is particularly adept at dealing with the interplay between different medical specialities that such claims can require.

His recent cases also involve spinal injuries, particularly cauda equina cases as well as traumatic injuries occasioned from e.g. car crashes or falls from height. He is also routinely instructed in cases involving head and brain injuries and his clinical negligence expertise assists him with dealing with and analysing the significant medical evidence that such claims can generate.

Given the nature of his caseload he encounters cases where surveillance evidence, in its various guises, is deployed and he has substantial experience of managing and addressing the same to the ultimate benefit of his clients.

Jonathan is also a keen cyclist and he is regularly instructed in potential PI claims arising from cycling collisions.

Away from medical devices he has also recently litigated personal injury claims concerning bicycles, tumble dryers, defective shower seats, and even balloons.

Modern Slavery

Jonathan is keen to continue to use his legal skills and experience to assist those who have been trafficked or subjected to forms of modern slavery. In his early years of practice he pursued a number of unpaid wages claims in the employment tribunal on behalf of vulnerable individuals as well as being counsel in criminal cases where such issues arose. In more recent times his practice focuses on personal injury and professional negligence and he is frequently instructed in very complex cases (factually, medically or financially) involving highly vulnerable individuals, which require astute handling to achieve the best possible outcomes for his clients.
