A motorway pile-up was caused by the negligence of Mick. Keith, who was in one of the cars involved in the accident but who was unhurt, suffered psychiatric damage from seeing the carnage. Ron, who had been in a car travelling in the opposite direction, helped to extract the injured from the wreckage and comfort them. Charlie, a farmer, who saw the accident, suffered shock from witnessing the distressing scenes, as did Bill, an ambulance man who helped in the rescue and took the wounded to hospital. Kylie also suffered shock when she saw her niece after she had been bandaged up. Hermione also suffered shock on being told at home that her son had been killed, and Angelika, the driver of one of the cars, became deranged due to her feelings of guilt for having innocently killed her workmate Chardonnay in the pile-up. Who can sue for negligence?
