Notable Personal Injury cases


Yordanov v Vasilev and Atanasov v Vasilev [2024] EWHC 1496 (KB).

Succeeded in obtaining judgment at a preliminary issue trial which concerns a high-speed road traffic collision. The claim involved arguments as to whether Bulgarian or English law should apply to the claim brought by Yordanov and is presently one of the leading cases on the interpretation of articles 4(2) and 4(3) of the Rome II regulations, which determine which law applies to a negligence claim.

JG v AC (Settlement 2024)

RTA in Guernsey governed by the law of Guernsey. The 20 years old Claimant suffered catastrophic injuries (C7 complete tetraplegia). Contributory negligence / causation issues raised regarding a failure to wear a seatbelt. Additional complexities to regular catastrophic spinal cord injury included the Claimant’s pre-existing learning difficulties, that proceedings had to be issued in Guernsey, the requirement to use 3 separate discount rates for different losses, and the limited care facilities available on Guernsey.

The claim settled for £23 million which is believed to be the highest ever out of court settlement for a case in Guernsey.

 

Fleming v Zurich Insurance plc [2023] EWCA Civ 1417, 2023 WL 08719002

Represented Mr Fleming, who had previously been acting in person,  on a second appeal before the Court of Appeal, on a pro bono basis through Advocate.  The appeal was allowed.

Claimant had pursued his claim in person for modest whiplash type injuries. He had permission to obtain a further medical report which supported a claim for a permanent injury to his spine. He had also been granted permission to rely on updated schedule. The statement of value at issue was up to £10,000. The updated schedule was pleaded at a figure of around £500,000.

The Claimant sought permission to amend the statement of value approximately 2 months before trial. Permission was refused before DDJ and CJ on appeal. Ian persuaded the Court of Appeal that Claimant ought to have been permitted to increase statement of value given previous case management directions. The judgement provides welcome clarity on scope of CPR 16.3(7) and the requirement to apply to amend the statement of value when the valuation is insufficient.

 

Alli-Balogun v (1) On the Beach (2) Zurich Insurance plc (3) Hosa Hotels (4) Insitut de Balear (5) Mapfre Espana (6) Meeting Point Youtravel (7) Viajes Sidecars (KBD, 2024)

A complex case involving a child who suffered severe brain injury as a result of nearly drowning in a swimming pool while in Spain.

The claimant was catastrophically injured so this is an extremely high value claim. The claim involved five defendants and two additional parties located in multiple jurisdictions. The assessment of damages involved the application of English and Spanish law, an issue rarely if ever previously considered by the court in a personal injury context.

Acted for the Fourth Party unled. Claim settled for a six figure sum.

Multiple Claimants v The Royal Papworth Hospital NHS Foundation Trust (2024)

Instructed to represent the family of two women who had been admitted to the Royal Papworth Hospital for lung transplant surgery. Following surgery and whilst under the care of the Trust they were exposed to the pathogen Mycobacterium Abscessus from the hospital water supply. An infection followed which required aggressive antibiotic treatment which ultimately led to the deaths of both women. The Coroner considered how the deceased came to be exposed to Mycobacterium Abscessus and in turn how Mycobacterium Abscessus came to be in the water supply. A prevention of future deaths report was issued to the Health Secretary to address, in particular, the relevant HTMs used at hospitals in respect of water supplied to immunosuppressed patients who are at an increased risk of Mycobacterium Abscessus infections.

IP v EP (KBD, 2022)
