L’Heureux-Dubé J.
L’Heureux-Dubé J. — A majority of us would allow the appeal. Unlike the Court of Appeal, we are of the view that the trial judge neither was mistaken about the purpose of the expert evidence nor abused his discretion in dealing with the expert’s testimony.
The appeal is accordingly allowed by a majority decision.
Iacobucci, Major and Arbour JJ. would have dismissed the appeal and adopted the reasons of LeBel J.A.
