18 As Winneke P said in R v Alexander and McKenzie,[4] where an appellate court is asked to set aside a verdict on the ground that a miscarriage has occurred as a consequence of the accused being tried jointly with the co-accused, the 'essential issue to be considered is whether any real injustice has been done to the applicant, as otherwise the proviso ... can be applied.'[5] We are satisfied that no miscarriage of justice was suffered by the applicant as a consequence of the joint trial. Shortly stated, our reasons are these. First, a considered decision was evidently made by counsel for Tilley, before the trial, not to seek a separate trial. It was, as will be seen, an entirely understandable decision, no doubt made after an evaluation of potential forensic advantages and disadvantages. Now, as we perceive it, complaint is made that, as it turned out, a forensic disadvantage was sustained. But in our view that complaint rests, despite the elaborate argument which we have detailed, essentially upon the fact of Tilley's conviction. Secondly, the Crown case against Tilley was strong independently of the content of Perrier's record of interview.
