The Crown applied on a voir dire to introduce expert opinion evidence from a collision reconstruction investigator in a trial for criminal negligence and dangerous driving causing bodily harm by street racing.
The defence conceded relevance, absence of an exclusionary rule, and proper qualifications, but challenged necessity and reliability.
The court applied the Mohan framework and found the evidence necessary and sufficiently reliable, noting that defence concerns went to weight rather than threshold admissibility.
The application was granted.
