The issue in this application was the admissibility of an expert report. The reports were challenged, inter alia, on the grounds that they were not necessary, that they usurped the function of the judge or jury, and that they contained opinions on matters of law. The Court reviewed both reports which contained assessments of negligence, interpreted and applied the Collision Regulations to the facts of the case, and rendered opinions on contributory negligence. The Court concluded that these reports went beyond the function of an expert and intruded into the exclusive roles of the judge and jury.
