Isaac has a specialist clinical negligence and personal injury practice. A large number of Isaac’s instructions relate to cases involving life-changing spinal and brain injuries, chronic pain and fatalities. Isaac is often instructed by defendants in cases involving allegations of fraud. He is ranked as a leading junior in personal injury and clinical negligence in both the Legal 500 and Chambers and Partners 2024.
Isaac is an experienced advocate with an excellent track record at trials, joint settlement meetings and mediations.
He also provides written advice on liability, quantum, evidence and procedure, drafts statements of case and advises in conference.
In addition to his civil practice, Isaac is often instructed to provide representation at inquests, particularly those arising from deaths in hospitals and road traffic accidents.
Isaac has a busy and varied clinical negligence practice, and has acted or advised in cases including:
- spinal cord injuries,
- negligent surgeries,
- sub-arachnoid haemorrhage,
- delayed diagnoses (including cancer),
- lower limb injuries, including diabetic foot and critical limb ischaemia cases,
- failure to obtain informed consent,

Isaac acts predominantly on behalf of claimants in his clinical negligence practice.
Whilst Isaac’s clinical negligence experience is very broad, he is particularly interested in cases involving sepsis or spinal cord injury.
Isaac’s clinical negligence work includes drafting pleadings, drafting agendas for expert meetings, advising on paper and in conference, and providing representation at JSMs, mediations and at court.
In addition to working on cases against hospitals and GPs, Isaac has been involved in cases involving claims against cosmetic practitioners and pharmacists.

Isaac is the author of A Practical Guide to Sepsis and Meningitis Claims, available here.
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 KC 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 KC.

- 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 KC. Reported on Westlaw and Lawtel.
Indemnity and coverage disputes form a core part of Isaac’s practice. He frequently advises insurers and/or the MIB 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:
- All aspects of the Uninsured Drivers’ Agreement 2015, including failures by claimants to pursue other sources of recovery, and clause 8 defences;
- Cases where proceedings have not been properly served on a tortfeasor and where the insurer or MIB has only a contingent liability under section 151, Article 75, or the UDA;
- Whether various types of use fell within the terms of a policy, including:
- use of a vehicle as a weapon;
- 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.Download section
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.
Isaac is frequently instructed in chronic pain and mild traumatic brain injury cases where exaggeration is an issue.
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 KC.
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.Download section

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  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  EWCA Civ 93 published in the PI Brief Update Law Journal.Download section

- Acting for a car manufacturer where it was alleged that the airbag of a vehicle was defective, and caused injury.
- A fatal case where a woman died in a fire caused by a faulty dishwasher,
- Several cases in which consumers were injured by faulty cooking equipment,
- A case in which it was alleged that a consumer was injured when riding a faulty quad bike.
Isaac has experience in a range of professional negligence work. He has recently advised in several negligence cases against solicitors for under-settlement of personal injury claims.
He has also acted in numerous claims regarding the allegedly negligent installation and maintenance of boilers and security systems.
Isaac is particularly experienced in advising in complex multi-party contribution and indemnity proceedings arising out of injury or property damage.Download section
