Recent cases:

G - Multiple injury, including brain injury suffered by a pedestrian hit by a bus, injury further complicated by a fresh brain injury after hospital discharge, yet again compounded by a poor outcome from a later remedial neurosurgical procedure. Claim complicated by the claimant's prior ankylosing spondylosis and paranoid schizophrenia.
M – Serious brain injury caused to pedestrian run over when crossing the road at night. Substantial dispute over liability and quantum complicated by pre-existing psychiatric conditions.
B - Lorry driver unable to retain an HGV licence and his employment, following facial injuries, the loss of one eye and severe psychological injury after being struck in the face by a defective container door.
D - Motorcyclist suffering nerve injury, psychological and spinal injury following a collision with a car, which turned in front of him. The quantum was complicated by the fact that he had suffered serious spinal injury in a prior accident. Inability to run a successful business and substantial losses arising.
B - Mesothelioma claim based upon exposure in the construction industry and complicated by circumstances of low exposure.
B - Acting for the widow of former engineer in electricity generating stations, who died of mesothelioma after asbestos exposure working in a number of different stations.
B - Acting for the family of a motorcyclist killed in a collision with a car. Claim complicated by the fact that the motorcyclist was travelling at extreme speed (over 100 mph in a 50 mph limit) when a car pulled out in front of him on the limits of visibility.
T - Acting for the family of builder killed when falling from a ladder whilst fitting double glazing. Liability was disputed on the basis that he was a self-employed sub-contractor responsible for his own working arrangements and health and safety and that the general work method was safe and the accident caused solely by his personal error.
A - Acting for the widow of a 70 year old professor of agriculture electrocuted by the domestic electricity supply of a privately rented house on a large country estate within a few weeks of taking the lease.
S - Acting for the widow of a driver killed in a road accident. The deceased witnessed an accident on a dual carriageway and stopped and walked back to assist the injured driver.

G - Severe, traumatic brain injury caused to a man hit by a double decker bus on a city centre pedestrian crossing at night, resulting in a catastrophic injury claim.
G - Teenage, rear seat car passenger suffered a severe traumatic brain injury following the loss of control of the car and collision with a tree, resulting in a catastrophic injury claim.
B - A flooded road caused the claimant to cross to the opposing carriageway and collide with an oncoming car.  The other driver suffered fatal injury and the claimant suffered multiple injury, including psychiatric injury causing him to take his own life 5 years later, leading to a Fatal Accidents Act claim.
