The Crown sought to qualify a police officer as an expert witness to provide opinion evidence regarding factual characteristics indicative of cocaine trafficking.
The defence objected on the basis that the officer was not properly qualified under the fourth Mohan criterion.
The court found that the Crown had not established that the officer understood her primary duty to the court rather than to the Crown.
The application to present opinion evidence was dismissed.
The charge was subsequently resolved by guilty plea to simple possession of cocaine.
