The accused was the director of the police force for the city of Mont Tremblant. When the collective agreement expired, the work atmosphere became more acrimonious. The accused was repeatedly subjected to intimidation and acts of vandalism. In response, he installed recording devices at the police station and in the room where the negotiations with the union for the renewal of the collective agreement took place. He was charged with interception of private communications within the meaning of the Criminal Code.

The jury acquitted the accused. It was argued that he had made a mistake with respect to the facts that would entitle him to intercept the communications and that he had acted in self defence in response to the intimidation directed against him. The Court of Appeal set aside the acquittal and ordered a new trial.
