  • Advising and drafting the letter of response in a professional negligence claim against solicitors concerning their handling of a claim arising out of personal injury caused by an allegedly defective bottle with broke which broke whilst being handled by a customer in a restaurant.
  • Advising on a claim for contribution against a supplier of firewood processors to a company whose employee had been injured using one of the machines.
