Recent examples of Isaac’s clinical negligence work are:

Personal Injury

Isaac acts for claimants and defendants in all aspects of personal injury including road traffic accidents, employer’s liability, occupier’s liability, product liability, public liability, cases under the Highways Act and cases under the Animals Act.

A significant portion of Isaac’s personal injury instructions arise from road traffic accidents.

Isaac is generally instructed in serious and catastrophic injury cases, including cases involving chronic pain, brain injuries, spinal injuries and fatalities.

Many of Isaac’s instructions for defendants involve allegations of fraud, or indemnity issues (see below).

Examples of Isaac’s work include:

  • • P v K (2021) – instructed for the defendant in a serious injury claim in which a young professional riding pillion on a motorcycle was negligently knocked down and suffered a severe knee injury. Settled at a JSM (unled) against a QC for less than half the claim’s pleaded value.
  • M v L (2020) – instructed for the defendant in chronic pain claim. There was a dispute as to whether the condition was organic or functional. Pleaded to £1.5m. Settled shortly after JSM for less than 30% of its pleaded value.
  • C v Y (2020) – instructed for defendant in a severe traumatic brain injury claim. Claim arose from quad biking on a dual carriageway. Liability and quantum were disputed. The claim was settled by a Calderbank offer on terms favourable to the defendant.
  • Re GA (2020) – instructed for claimant in a motorcycle accident claim causing significant orthopaedic and psychological injuries in which quantum was complex due to the claimant only having recently embarked on a career which he would now have to abandon, and due to pre-existing medical issues. The claim settled pre-issue for a substantial sum.
  • Newell v Lily Communications – finding of fundamental dishonesty in an EL liability trial against a telephone salesman who claimed to have suffered a significant injury to his back at work. Before HHJ George.
  • Nicholson v Thomas – finding of fundamental dishonesty against a former prison guard who exaggerated his injuries following a serious road traffic collision. Decision of HHJ Owen QC.
  • M v X Local Borough Council and Other – represented a third party in a serious injury claim arising from a slipping accident at a party. Settled at a JSM, at which Isaac appeared unled against a QC.
  • A v C – acted for the Claimant in a case brought under the Animals Act after she was injured by a neighbour’s dog. Settled following a settlement meeting for £50,000.
  • Khalid v AXA  – successfully had claim struck out for fraud upon conclusion of the Claimant’s evidence in a liability disputed road traffic accident. QOCS disapplied and costs ordered.
  • English v Burnt Mill Academy Trust – instructed for Defendant where the Claimant was a schoolboy who fell over a bollard which served no purpose and was removed after the accident. Claim dismissed. Decision of HHJ Moloney QC. Reported on Westlaw and Lawtel.

Isaac has a growing practice in advising insurers on policy and coverage disputes, particularly in the context of road traffic accidents. He is often instructed to draft defences or to advise in cases where indemnity disputes arise between insurers and their policyholders. He is also frequently instructed to advise insurers on their status as against other insurers.

He has recently advised in cases involving the following issues:

  • Whether various types of use fell within the terms of a policy, including:
    • use of a vehicle as a weapon;
    • racing;
    • fast food delivery;
  • Whether the correct insurer to conduct a defence was an EL or motor insurer, and how to resolve the issues between those insurers;
  • Whether an uninsured defendant who conducted her own defence and satisfied her own judgment could be liable to the MIB in costs.

He frequently delivers training on insurance indemnity and cases involving the Motor Insurers’ Bureau (‘the MIB’). He has recently written a case comment on the important decision of Advantage Insurance v (1) Stoodley (2) Trinity Lane, which was concerned with the liability of insurers providing cover under a DOC extension.

He also acts for claimants in cases against the MIB.

A signification proportion of Isaac’s personal injury practice involves cases containing allegations of fraud including fraudulent exaggeration, LVI, and induced accidents.

Isaac is regularly instructed to advise in writing and in conference on behalf of defendants in cases where fraud is suspected.

He is familiar with the application of section 57 of the CJCA 2015, and has frequently had QOCS disapplied on the basis of findings of fundamental dishonesty.

In Pajapati v Smith (2020), the claimant brought a claim for personal injuries and credit hire. Isaac represented the defendant at trial. The Deputy District Judge made a finding of fundamental dishonesty, but also took the unusual step of striking out the entire claim on the basis of a falsely verified statement of truth.

In Nicholson v Thomas (2018), Isaac was instructed for the Defendant in a claim arising from a serious road traffic accident, in which the Claimant was knocked off his motorbike, and suffered spinal fractures. The Defendant’s investigations included obtaining surveillance evidence which suggested exaggeration. Isaac successfully obtained a finding of fundamental dishonesty before HHJ Owen QC.

In the case of Khalid v AXA (2017), Isaac successfully applied to strike out the claim upon the conclusion of the Claimant’s evidence. QOCS were disapplied. A report on the case can be found here.

In another case, (1) Howell (2) Walker v Brindley Asphalt Ltd (2017), Isaac represented the Defendant; following a two-day trial, C1’s claim was dismissed upon an application under section 57 CJCA 2015 for a finding of fundamental dishonesty, with an order for indemnity costs – a case summary can be found here.


Isaac has experience of acting in inquests, especially those involving hospitals.

Isaac has been instructed both by families, and by other interested persons, including retirement homes. He has also been instructed by the insurers in cases with a personal injury background, particularly in deaths arising from road traffic accidents.

In addition to representation at inquest hearings, Isaac advises interested persons in preparation for inquests, and is happy to attend pre-inquest reviews.

Isaac has recently acted in the following inquests of note:

  • Re B – hospital inquest where the deceased, who was suffering from terminal cancer but was not on an end-of-life pathway, was administered a toxic dose of morphine and died due to overdose. The Coroner made critical findings, recorded in a narrative conclusion.
  • Re Whittow and Stokes – road traffic accident inquest, where Isaac acted for the insurer of an elderly driver with Alzheimer’s Disease involved in a fatal road traffic accident. The inquest was reported in the national press, including the BBC  and The Times.
  • Re P – hospital inquest where the deceased had died from sepsis following a post-surgical infection. Isaac was instructed by the family.
  • Re W – hospital inquest where the deceased had died following a failure to prescribe and administer anticoagulants. Isaac was instructed by the family. The Coroner made a finding of neglect.
  • Re G – the deceased suffered smoke inhalation injuries after her Hotpoint dishwasher caught fire. Isaac was instructed by the family. Hotpoint instructed a silk.
  • Re J –hospital inquest where a child had died from sepsis. The Coroner made a finding of neglect. A full case note is available on the 12KBW website. The case has also been reported in the The Sunday Times.
Credit Hire

Isaac has considerable experience and expertise in representing defendants in credit hire matters. He is extremely familiar with all the leading decisions and is frequently asked to advise on behalf of insurers, both in respect of individual cases and in respect of general tactics and strategy.

Isaac recently acted for the successful appellant insurer in the High Court appeal of Axa Insurance Ltd v Lakhani [2021] 4 WLUK 153, before Mr Justice Johnson.

He has written a number of articles and case comments on credit hire, including a comment on Stevens v Equity [2015] EWCA Civ 93 published in the PI Brief Update Law Journal.
