Harry Lambert is Barrister and Coroner specialising in the areas of product liability, clinical negligence, and human rights law. He is also renowned for his expertise in group litigation claims relating to these areas.

Harry is one of the leading Product Liability juniors at the Bar. He is ranked in Band 2 in Legal 500 where he is described as someone who “knows the area like the back of his hand”. He acts for both claimants and defendants and, over the years, Harry has acted for and advised some of the world’s largest companies, including News Group Newspapers, one of the world’s largest oil companies, and a household name electronics company, amongst others. He also acts for SMEs such as a national gas distributor, a healthcare equipment company and a manufacturer of e-cigarettes, amongst others. He was recently part of the core trial team for News Group Newspapers in Prince Harry’s Phone Hacking claim, and was the Lead Junior in the Lord Watson / Sun matters.

He is also at the forefront of thought leadership on the law and emerging tech and is the Founder of the Centre for Neurotechnology and Law, whilst his 15-part series on Neurotechnology & The Law has garnered academic acclaim and been turned into a podcast run by the Italian equivalent of the Financial Times. Harry’s expertise on neurotechnology is such that he is asked to speak all over the world and he has given or is giving talks in inter alia Spain, Italy, Turkey, India, Australia, Canada, Ethiopia and Chile.

He has also carved out a unique market reputation at the intersection of law, social media and AI. Harry has written extensively on the subject, including on tortious liability for algorithmic wrongs in JPIL, and a 3 part series in the NLJ asking whether social media can be conceptualised as a defective product.

This expertise drives his practice: Harry acts for a number of bereaved parents who have lost children to social media harms including the high-profile Ellen Roome inquest involving the ‘Blackout Challenge’.

He has been described, variously, as a “visionary” and as the “Michelangelo of the Product Liability Renaissance”.

Harry’s intimate knowledge of cutting edge assistive technology and industry contact also add real value in Harry’s heavyweight Clinical Negligence practice encompassing claims in, inter alia, the fields of obstetrics, neurosurgery, paediatrics, orthopaedics and cardiology. He acts for both Claimants and Defendants.

Harry has particular interest and expertise in amputation cases and is familiar with the highly specialised issues to which such claims give rise. This is a practical, fast-moving sub-speciality of Personal Injury and Harry combines knowledge of the latest prosthetics, with a “problem solving” attitude and a rigorous legal analysis.

Overall, Harry strives to combine excellence with approachability; intellectual rigour with a down-to-earth attitude and common sense. He provides advice with meticulous detail (“a very detailed and focused counsel, who never misses a trick” – Legal 500) but if matters go to trial “Harry is a fierce advocate who is able to think outside the box” (Chambers & Partners 2023) and who “fights his corner hard” (Chambers & Partners 2021).

Expertise

Harry is one of the leading Product Liability juniors at the Bar. He is ranked in Band 2 in Legal 500 UK, who commented that he “knows the area like the back of his hand”; is “a thorough, hardworking barrister” with a “superb intellect”; “outshines his contemporaries” and “impresses with his intelligence, enthusiasm, diligence and manner”.

In Chambers and Partners, he is said to “fight his corner hard” and “he is at his best when handling cases with complex and novel legal issues.”

He acts for both claimants and defendants and has particular expertise in cases involving drugs and medical devices such as the Hepatitis B vaccine, vitamin supplements, and medical aids, as well as the nationwide commercial recall of intra-ocular lenses. Harry has been instructed in many of the big product liability cases of recent years including: Metal on Metal Hips, Thalidomide and the Seroxat litigation in which Harry conducted a hearing against two KCs. It was listed as one of the Lawyer Magazine’s “Top 20 cases of 2019”.

He successfully defended a claim relating to a state-of-the-art custom knee prosthesis using advanced imaging and design, a claim involving new-generation Cochlear implants, and a claim regarding automated eye testing.

Recent instructions include acting without a leader on a cross-jurisdictional pharmaceutical dispute in the Court of Appeal, advising the NHS in relation to Oculentis claims, and acting on behalf of one of the major product manufacturers in the Grenfell Litigation.

This work can also involve cross-over with the coronial jurisdiction (where Harry also sits as a Coroner). Harry recently acted for a world-leading electronics manufacturer, following a residential fire started in or around the printed circuit board of a television. Both the family of the deceased and the Fire Brigade had suggested that Harry’s client had manufactured the television involved in the fire. However, Harry successfully argued that the identity of the manufacturer and/or precise mechanism of failure were out of scope or, alternatively, insufficiently evidenced and Harry’s client was not mentioned in either the Inquest Conclusion or Inquisition.

His product liability work can be broadly split into medical and non-medical cases, as follows:

Medical Devices & Pharmaceuticals

Over the years Harry has acted in many cases involving drugs and medical devices.

Examples of the former include the Seroxat litigation, a cross-border case of alleged pharmaceutical fraud, and a fascinating case concerning the Hepatitis B vaccine.

Examples of the latter include claims concerning insulin pumps, an allegedly defective surgical cutting guide, and a bathroom hoist which broke [rendering a paraplegic user tetraplegic].

Harry’s background in clinical negligence also gives him a real advantage here. For example, he acts for the NHS on matters relating to the nationwide commercial recall of intra-ocular lenses. His knowledge of commercial product liability law, medical law, as well as familiarity with the underlying pathology, have been of tangible benefit to the client in this complex multi-factorial area of the law.

Non-Medical Cases

Harry also has experience in cases concerning white goods and was involved in the Shepherd’s Bush Fire litigation as well as a high-profile inquest against Whirlpool arising out of two deaths in 2014. Both these cases were cited in the Business, Energy and Industrial Strategy Committee report entitled The Safety of Electrical Goods in the UK.

With his background and reputation in product liability, Harry brings particular expertise in matters brought or defended under the Consumer Protection Act 1987. This also makes him particularly adept at dealing with complex causation cases such as those involving concurrent, competing or cumulative causes.

Property Damage; Fires, Floods and Explosions

Harry’s property damage cases include those involving fires, floods and explosions.

Harry acted for a gas network distributor, one of whose pipes had exploded, causing both significant personal injury and property damage. Harry’s client was absolved of all blame and the claim dismissed, following a contested High Court trial. Harry acted alone against a leading silk and was victorious on all live issues in dispute.

Examples of recent cases include:

  • Shepherd’s Bush Fire litigation
  • Grenfell Litigation
  • Acted in a case brought by a faulty pressure-reducing valve causing a flood – this case involved complex questions of causation and issues under the Companies Act 2006.
  • A restaurant destroyed by a fire caused by tortiously accumulated grease deposits. This case raised issues concerning the proper scope of the Berni’s Inns principle.
  • A fire in a block of flats allegedly caused by a defective DVD player.
  • Property damage and consequential losses arising out of defective industrial scale paper.
  • A subrogated claim on behalf of an insurer against Apple Incorporated in relation to an iPad allegedly causing a house fire.

Harry acts for Claimants, the NHSR and the medical defence organisations. He has a heavyweight Clinical Negligence practice encompassing claims in, inter alia, the fields of neurosurgery, paediatrics, obstetrics, orthopaedics and cardiology.

He has experience of complex clinical negligence areas such as birth cases and Erb’s Palsy; areas which require a considerable degree of sub-specialism.

He acts as sole counsel in high-value or complex clinical negligence litigation.

Harry also acts in related clinical negligence inquests, again of the utmost complexity. He recently undertook a very high-profile clinical negligence inquest over more than 3 weeks, with 54 witnesses and 5 medico-legal experts. Harry cross-examined more than 30 doctors/nurses/experts. He secured a conclusion of Neglect, a finding that Article 2 applied and a wide-ranging Prevention of Future Deaths Report.

He acts for both Claimants and Defendants in cases of the utmost value and across all areas of personal injury including workplace accidents, public liability and RTAs.

Harry robustly defends cases both on paper and in court.

Recent examples include a case discontinued after Harry’s strike out application on Duty of Care; winning an Employer’s Liability trial notwithstanding the admitted absence of a risk assessment; and succeeding on both limitation and breach following a 2-day NIHL trial.

In a recent multi-track HAVS trial, Harry’s client retained no documents but he nevertheless successfully defended the claim on the issue of medical diagnosis (CTS vs. HAVS) after rigorous cross-examination of the Claimant’s expert. Harry also recently acted in a highly confidential multi-million-pound claim involving the death of a high-profile individual.

Amputations and other Serious/Catastrophic Personal Injury

Harry has particular interest and expertise in amputation cases and is familiar with the highly specialised issues to which such claims give rise. This is a practical, fast-moving sub-speciality of personal injury, where having the right counsel can make all the difference. Harry combines knowledge of the latest prosthetics, with a “problem solving” attitude and a rigorous legal analysis.

In the case of M, Harry acted for the Claimant in a case involving 7 expert disciplines, which settled minutes before Harry’s opening speech, when the Defendant accepted his old Part 36 offer. Harry had conduct throughout and attended two RTMs, rejecting two high offers before the Defendant eventually ‘blinked first’.

Harry has acted in upper limb and lower limb cases, acting for both claimants and defendants.

Harry also has considerable experience of serious/catastrophic personal injury. He prides himself on fusing attention to detail, which is often the key in such cases, with a user-friendly presentation. He takes pride in producing detailed, persuasive Schedules and Counter Schedules. One such case settled following novel arguments on the nature of general damages in Jersey and the cost of investment advice.

Harry has conducted conferences with leading figures in the world of serious/catastrophic PI.

Harry is familiar with the Brussels Recast regulations and has advised on issues of jurisdiction and choice of law or forum involving numerous European countries i.e. Spain, Holland and Germany. Many of his cases also involve foreign manufacturers, clients or other corporations such as those based in USA, China and Denmark. On more than one occasion, Harry has acted in cases abroad.

Harry acts in a number of personal injury cases instructed by Jersey-based solicitors, and has advised on matters of Jersey law.

He has also been involved in numerous Human Rights cases with an international element, some of which involved the application of foreign law. In 2011, Harry successfully took a case on the interplay between personal injury and state immunity to the Employment Appeal Tribunal (Nigeria v Ogbonna [2012] 1 W.L.R. 139).

In recent years, Harry has also developed an expertise in military claims against the Ministry of Defence. Harry recently advised in a case concerning military personnel injured whilst stationed abroad and is currently instructed as the lead junior in the Rotary Aircraft Litigation, involving the alleged exposure of ex-military aircrew to toxic emissions.

He is a member of the Pan European Organisation of Personal Injury Lawyers (PEOPIL) and the British Institute of International Comparative Law (BIICL).

Harry sits as an Assistant Coroner in Inner London North covering Camden, Islington, Tower Hamlets and Hackney.

As counsel he has considerable experience of the coronial jurisdiction and attends inquests nationwide.

Harry recently acted for a world leading electronics manufacturer, following a residential fire started in or around the printed circuit board of a television. Both the family of the deceased and the Fire Brigade had suggested that Harry’s client had manufactured the television involved in the fire. However, Harry successfully argued that the identity of the manufacturer and/or precise mechanism of failure were out of scope or, alternatively, insufficiently evidenced. Harry’s client was not mentioned in either the Inquest Conclusion or Inquisition.

Harry attended a 4-day inquest on behalf of a leading Healthcare Equipment company. Despite extensive criticisms by the CQC at the outset of the coronial proceedings, Harry’s client was absolved of all and any blame.

Harry also has neighbouring experience in the regulatory context, having acted in numerous cases in the Health Professions and Nursing & Midwifery Councils.

Other examples of his inquest work include:

 

  • A high-profile inquest, which has attracted national media attention, in which a residential flat was destroyed in a fire allegedly started by a faulty electronic

His human rights practice has a particular focus on Articles 2, 3, 4, 8, 9 and 10:

Article 2

This typically arises in Harry’s clinical negligence practice and Harry often sits as a Coroner in Article 2 inquests, including in the prison/mental health context. He recently advised in a fascinating and high profile case which concerns the liability of prison services and an electronic tagging company for a horrific murder committed by a prisoner on parole.

Articles 3 & 4

Harry’s Human Rights work has included various cases involving torture, human trafficking and forced labour.

 

Harry has particular experience and expertise in issues relating to human trafficking. He played a major part in the two leading cases on trafficking; Galdikas [2016] EWHC 1376 (QB) and Antuzis [2019] EWHC 843 (QB), which paved the way for future claims. In the latter, Harry conducted the trial without a leader and secured 100% of the “as pleaded” figures for lost earnings for all eleven claimants.

Harry also acted in another high-profile trafficking/forced labour matter (name confidential). Harry drafted all of the pleadings and then, before Mr Justice Jay, successfully obtained a freezing injunction leading to settlement. Harry is adept at advising on corporate liability/supply chains.

Notable Human Rights cases


Kamoka v Security Services [2019] EWHC 290 (QB)

The case concerned Libyans seeking damages for their detention between pending deportation to Colonel Gaddafi’s Libya under the deportation with assurances programme (DWA) and on the basis of documents showing the UK security services were at the time involved in unlawful rendition.

Ali v MOD & FCO [2019] EWHC 3172 (QB)
