"Is it implicit in the Crown's reasoning .... that in relation to type 2 material, had the trial judge made different rulings concerning disclosure, this would have had such an impact on the conduct of the trial so as to make the verdicts unsafe?"
"It is apparent that the conditions which permit the court to order a retrial are twofold: the court must allow the appeal and consider that the interests of justice require a retrial. The first condition is either satisfied or it is not. The second requires an exercise of judgment, and will involve consideration of the public interest and the legitimate interests of the defendant. The public interest is generally served by the prosecution of those reasonably suspected on available evidence of serious crime, if such prosecution can be conducted without unfairness to or oppression of the defendant. The legitimate interests of the defendant will often call for consideration of the time which has passed since the alleged offence, and any penalty the defendant may already have paid before the quashing of the conviction."
