Personal Injury

Andrew is highly thought of for his personal Injury practice which has a particular focus on catastrophic, spinal and closed head injuries. These include cases of employers’ liability, occupiers’ liability and
road traffic accidents. Specialist advice is offered in claims with conflicting, complex medical evidence for example with orthopaedic, neurological or psychiatric disputes or where pain disorders are challenged. Work is divided between Claimant and Defendant and includes extensive experience at trial and in a pre-trial advisory capacity of industrial disease litigation (including group actions) in the form of deafness, asbestosis, dermatitis, WRULD and HAVS. He is very experienced in cases of NIHL of all types and has ongoing involvement in test litigation where the applicability or otherwise of the Coles Lutman Guidelines to BT engineers exposed to tonal noise is being addressed. The acute difficulties of cases involving exposure to asbestos with mesothelioma are regularly and sensitively addressed as are the problems presented litigating high value cases worth over one million.
