David recently acted for a claimant in a claim who was prior to the relevant negligence non-verbal and severely autistic in any event.

Examples of cases in which David has been involved include the following.

The claimant suffered overwhelming sepsis and a cardiac arrest, which led to a long stay in ICU and critical care myopathy, causing life changing disabilities. David acted for a young woman who suffered severe bleeding as a result of a negligently performed hysterectomy. This caused severe nerve damage and a footdrop. David is currently acting for the claimants in a case in Trinidad and Tobago. This involves an allegedly unnecessary embolisation procedure to the brain, resulting in a stroke. David is acting for young woman who underwent below knee amputation as a result of a failure to diagnose and act upon compartment syndrome following an ankle replacement operation, and for a young man who suffered a below the knee amputation as a result of a negligently performed ankle replacement.

Notable Clinical Negligence Cases



David acted for the appellant Purchase in the combined appeals of Paul, Polmear and Purchase [2024] UKSC 1 in the Supreme Court. This was a much anticipated appeal concerning secondary victim claims in clinical negligent settings.



A claim against a neurosurgeon and neuro adiologist (in the High Court of Trinidad and Tabago) in relation to an allegedly unnecessary onyx embolisation of blood vessels in the brain leading to a stroke in a previously fit and active young woman.



A claim involving the failure to diagnose in time a rare condition known as hyperoxaluria (the overproduction of oxalate causing recurrent renal stones, and if untreated nerve damage). The delay caused kidney failure and the need for lifetime dialysis, bilateral lower limb amputations and bilateral defunctioning of both upper limbs.



Numerous birth injury cases involving catastrophic brain injuries and/or lifelong neuro disabilities caused by a number of mechanisms, including acute hypoxia, a skull fracture at birth, and extreme prematurity.



A claim involving surgical errors during total ankle surgery, resulting in the tenting of a major nerve and intractable pain. This later led to a below knee amputation.



A cauda equina syndrome claim against a hospital trust in relation to failures by an A&E department in relation to which liability was established at trial. It was successfully argued on behalf of the Claimant that she was entitled to the cost of 24 hour care under the Reaney principal, in spite of the fact that she would have had a need for 24 hour care of a different quality, but for the breach of duty.



A. cauda equina syndrome claim involving the omissions of GP and two hospitals, which was settled out of court.



A cauda equina syndrome claim by a prisoner against a private prison service and a hospital trust in relation to failure to act upon signs of cauda equina syndrome in prison and in hospital. This was settled out of court.



A claim in relation to alleged negligent failures in a hospital A and E department to recognise and act upon signs of a subarachnoid haemorrhage. This caused long lasting serious neurological injuries (likely to require lifelong care) in a six-year-old boy.

A claim involving the failure by urologists in a hospital to identify and refer for investigation signs of testicular cancer in a non-verbal young man with severe autism. The cancer was eventually successfully treated, but the spread of the tumour caused paralysis and double incontinence. The claim involved particularly difficult quantum issues as to the relevance of different care needs in any event and the provision of ongoing NHS Continuing Healthcare.



A high value fatal accidents claim involving alleged negligence on the part of. the hospital for failing to administer thrombylosis to a young man who was suffering from a severe pulmonary embolism.



A claim involving the failure adequately to advise the claimant on reasonable alternatives to proposed surgery to remove a very slow going and likely benign tumour with the result that the Claimant underwent and operation that caused an infarcted spleen, and complications leading to the inability to swallow solid food.



A claim involving the negligent insertion of a tube the wrong way round into a cardiopulmonary bypass machine during a standard aortic heart valve replacement operation. This led to an air embolism and a catastrophic brain injury.


Personal Injury

David has extensive experience in all main areas of personal injury law, in particular cases involving serious injuries and
fatalities. He has long experience of appearing in inquests on behalf of bereaved families and bringing claims against the MIB in relation to uninsured and untraced drivers. He has successfully appealed a decision of the MIB to designate a claim as untraced rather than uninsured. David has recently acted or is currently acting in catastrophic/multiple injury claims involving road traffic collisions involving pedestrians and cars, pedestrians and cyclists and passengers in vehicles, workplace accident claims, and fatal accident motor claims. David often lectures to solicitors and organisations on various personal injury topics and has recently been invited to do so for PIBA, MASS, BRAKE and the Expert Witness Institute.

Catastrophic Injury

Catastrophic personal injury claims form a substantial part of David’s practice. David has long experience of dealing with. cases involving catastrophic injuries, including brain and spinal injuries. David is particularly aware of the practical needs of catastrophically injured clients and their families. He recognises the importance of meeting clients to discuss their needs at  the earliest possible opportunity, where preferred at their homes. He is familiar with the practical issues of implementing care regimes and acquiring suitable accommodation pending settlement or final hearing through. the rehabilitation code or by obtaining interim payments. He has a proven track record of successfully obtaining interim payments through contested interim payment hearings. He has considerable experience of liaising with IFAs to secure lasting funding for clients through PPOs in both full and partial liability cases, in the latter cases where the full care regime must be achieved through a workable combination of PPs and local authority or NHS provision.

Notable Personal Injury Cases



Claim on behalf of pedestrian in collision with a car who sustained a catastrophic brain jury.


David Tyack KC

Claim on behalf of mother and infant son who were both passengers in Deceased’s vehicle. Mother sustained multiple serious injuries. Infant son sustained catastrophic brain injury and is likely to require lifelong 24 hour care.

Claim on behalf of passenger in a car who sustained life changing polytrauma, including unusual and extremely serious arterial injuries, threatening viability of lower
limbs bilaterally, and at a number of levels. Claimant’s condition as it is resulted in significant care and accommodation needs.



Appeal to the Supreme Court on behalf of the Appellant Purchase in the combined appeals of Paul, Polmear and Purchase [2024] UKSC 1. The decision results in a very significant restriction of secondary victim claims in clinical negligence cases but has preserved and removed some restrictions on secondary victim claims in personal injury cases.


Inquests, Public Inquiries & Coronial Law

David practices the following areas:

Inquests, Public Inquiries & Coronial Law (Clinical Negligence)

David has acted on behalf of families in a number of high profile inquests involving extremely sensitive issues and considerable media interest.

He is acutely aware of the sensitivities of the issues for all concerned in the inquest, but ensures that the family’s concerns are clearly explored and put as necessary.

Examples of inquests in which David has acted for families include an inquest touching upon the death of an infant who died as a result of negligence during open heart surgery, an inquest touching on the death of a young man who died as a result of a severe primary embolism, and an inquest in relation to a young man who died during kidney dialysis. In the latter case, the young man bled to death when a lead into the dialysis machine became detached and was not investigated, in spite of an alarm being sounded. The Coroner accepted the family’s submission that the case should be dealt with as an Article 2 inquest and found systemic failures. The relevant hospital trust was later fined more than £1 million for health and safety breaches.

Inquests, Public Inquiries & Coronial Law (Personal Injury)

David has represented the families of the bereaved at numerous inquests. He has represented families in a number of high profile inquests which have often attracted media attention. He has acted in inquests touching upon the deaths of a very wide cross-section of the community from young children to senior citizens. David is aware of the sensitivity of each and every case for all involved, but is always concerned to ensure that the family’s concerns or aired and put as directly as may be required.
