Personal Injury

Personal injury forms the majority of Frederick’s practice. He is recognised as a Leading Junior in the Legal 500 in this field. His work is approximately divided equally between Claimants and Defendants. Frederick is instructed at all stages of proceedings, from interim applications and CCMC’s through to trials. He appears in court on a near daily basis. He has appeared unled in both the High Court and Court of Appeal in cases within this area.

Recent cases have included:

  • Acting for the claimant in a case brought under the Animal’s Act for serious facial and dental injuries sustained when kicked by a horse in the course of employment. Despite liability being in issue, the case settled in the Claimant’s favour in a high six figure sum following negotiation. It is notable that this case is one of a large volume of cases in which Frederick has been instructed, now into double figures, involving damage inflicted by horses.
  • Acting for a defendant motorist in a case involving serious orthopaedic injuries caused in a collision with a pedestrian. In a split trial the claim was dismissed on the basis that no liability attached to the motorist
  • Acting for the claimant in a fatal accident claim proceeding in the Queen’s Bench Division of the High Court following a high speed road traffic accident. Following Frederick’s involvement at all interim stages and in an advisory capacity the case settled in a high six figure sum shortly prior to trial
  • Acting for the claimant in a large claim for chronic pain (fibromyalgia). Frederick successfully obtained a significant settlement having been involved in the claim from the outset
  • Acting for a defendant motorist in a large (£40,000) credit hire claim with a counter-claim for life changing personal injury and traumatic brain injury. At a split trial the claim was dismissed and judgment was given in favour of the defendant/part 20 claimant. The case subsequently settled favourably for Frederick’s injured client.
  • Successfully obtained two findings of fundamental dishonesty in a single week while acting for Defendants in fast track cases where LVI was alleged
  • Acting for a major airline in a case brought under the Montreal Convention. Frederick was able to obtain a drop hands settlement after advising in conference and assisting in the drafting of correspondence

Frederick provides advice on quantum, liability and tactics either following pre-trial conferences or on the papers. He is particularly sought after by Defendants in cases where fraud or fundamental dishonesty is alleged.

Frederick has a familiarity with cases in the Travel Law sphere and is regularly instructed to appear in court or draft pleadings on behalf of Claimants and Defendants in cases brought under the Package Travel Regulations, Montreal or Athens conventions.

As a result of his previous career as an outdoor instructor Frederick maintains a particular interest in accidents arising out of participation in supervised high risk or ‘extreme’ sports. He has recently advised on cases involving rock climbing, scuba diving, skiing and horse riding. He is often instructed to advise on jurisdictional issues where such accidents have occurred abroad. Frederick has recently been regularly instructed to advise and provide precedent documents following the UK’s departure from the European Union.

Frederick is happy to consider conducting appropriate cases for claimants on a CFA basis.
