Gowers v Bifrangi UK Limited (2024)
Carwyn acted for the Defendant in this employer’s liability matter. Whilst liability had been admitted, causation and quantum were complicated. The Claimant claimed to have e suffered a deterioration in his pre existing cellulitis and was seeking significant damages. The Defendant’s vascular expert attributed only a minor injury to the accident. The claim was complex due to the type of injury, causation issues and the risk to both sides. The claim settled.
Howells v Treorchy and District Businessmen’s Club (2024)
Carwyn acted for the Defendant in this Occupiers Liability Act 1957 case. Liability had been admitted. The claim was complicated by the fact that the Claimant had pre-existing disabilities that required him to use mobility aids, including a scooter. There was a difficult question as to whether the Claimant was able to maintain an accommodation claim on a Swift v Carpenter basis, or whether some other methodology was needed or no recovery should be allowed. The claim ultimately settled at a JSM.
Murphy v Pryor Farms Ltd (2023)
Carwyn acted for the Defendant in this case arising from the amputation of the Claimant’s left lower leg following an accident at work. The Claimant was aged 17 at the time and working on the farm of a family friend when they dropped a significant weight onto the Claimant resulting in the decision being taken to amputate the lower limb. The Claimant had ambitions originally to join the RAF as a pilot. The Claimant has made a good adjustment to the effects of the injury.

HP
Carwyn acted for the Claimant in this multi-track matter proceeding in the High Court. He was led by Rhiannon Jones QC. The Claimant was knocked over by a car suffering serious injuries, including a significant brain injury. Liability was disputed. In addition, complex arguments existed in respect of quantum and around the issue of capacity. The claim was compromised at a JSM and the settlement approved by the Court.
Abellio London Limited v Ahuja and Ahuja
Carwyn represented Abellio in this matter arising from a road traffic accident. Whilst liability for the accident itself was not disputed the Defendant’s case was that it was so minor that the Claimants could not possibly have suffered any injury at all. At the trial in the County Court the claims brought by Mr and Mrs Ahuja were dismissed and they were found to be fundamentally dishonest. Abellio then commenced committal proceedings. The contempt was admitted.
Pop
A fatal accident at work where the deceased was crushed by the load that he was delivering. Carwyn represented an interested party in this inquest. There are several interested parties in this matter with the inquest considering the complex delivery network and opportunities to check the suitability of the load prior to the accident. Carwyn has attended several pre-inquest reviews in this matter with the full inquest scheduled to take place towards the end of the year.
Hatt v Hertfordshire County Council
Carwyn acted for the Defendant in this matter that arose as a result of an assault at school. The Claimant was claiming a substantial amount as a result of the psychological impact of the assault and other alleged incidents of bullying suffered.
