This case takes place in New Jersey and involves a man who was involved in a reasonably low-speed car crash. The man was stopped at an intersection when his vehicle was struck from behind by another driver. The driver claims to have suffered several debilitating and chronically painful injuries as a result of the accident, on which grounds he has sued the driver of the other car. The defendant claims that the speed of the impact was likely too low to result in the injuries that the plaintiff claims to have suffered, and that the plaintiff’s injuries must have existed before the crash occurred. To this end, the defense sought to retain a nuclear medicine expert witness to opine on the timing of the plaintiff’s injuries.
