Jason has a specialist practice focused on high-value personal injury and clinical negligence work.

He is highly regarded for his keen eye for detail, expertise in handling complex expert issues and formidable cross-examination skills. Many clients instruct him as an alternative to using leading counsel in catastrophic claims.

Away from the Bar, Jason lists his interests as rugby and cricket (now only as a spectator), cycling and skiing (as a participant) and music.

Areas of Expertise
  • Personal Injury

    For many years, Jason had a broad personal injury practice, acting for both Claimants and Defendants in all types of personal injury case in all parts of the country.  However, his personal injury practice is now focused on accident cases leading to serious or catastrophic injury or fatality.

    He has undertaken several lower limb and hand amputation cases in the last two years, acting for Claimants and Defendants and is familiar with the expert issues which arise in this type of case, including prosthetics, care and OT and accommodation.

    A large part of his work in recent years has involved moderate and severe brain injury cases, again acting for Claimants and Defendants, in cases with contested liability issues and complex quantum issues, including cases involving pre-accident disability and care needs.  In many of these cases, Jason acts alone against leading counsel.  He is very familiar with the expert issues which arise in such cases and also the implementation of Periodical Payment Orders.

    He has several ongoing cases where video and social media evidence is being used to demonstrate exaggeration and a finding of “fundamental dishonesty” is sought.

  • Clinical Negligence

    Jason has a well-established practice in clinical negligence work, acting for both Claimant and Defendants, including private medical providers.

    Jason has very extensive experience of litigating and settling complex clinical negligence cases, including several cases with multimillion values and including PPOs.

    Examples of his recent and current case load include cases related to;

    • Delay in management of cauda equina syndrome
    • Surgical negligence (spinal, orthopaedic, head and neck surgery)
    • Anaesthetic negligence
    • Missed/delayed diagnosis by radiologists
    • Stroke management
    • Management of community acquired pneumonia.

    He is frequently instructed on behalf of insurers considering contribution claims which raise clinical negligence issues.

    Jason also has considerable experience of acting for families at inquests involving possible clinical negligence.

  • Counter Fraud

    Jason has advised various insurers in cases where there is a suspicion of fraud, including evidence management and trial preparation.

    He has conducted many trials where allegations of fraud and / or malingering are made, including alleged high value cases with video evidence.  He has successfully recovered substantial costs against Claimants who have exaggerated their claims at first instance and in the Court of Appeal in Hullock.
