Mahmood v Western Australia

This case concerned an appeal by the appellant, Mahmood, against his conviction in the Supreme Court of Western Australia. The dispute arose from the prosecution's decision not to tender a full video recording of the appellant's re-enactment of events, despite the defence seeking to tender it. The prosecution had only consented to the tender of a portion of the video, arguing the remainder was "self-serving". The High Court of Australia considered whether the trial judge erred in refusing to allow the defence to re-open its case to tender the whole video and whether a direction to the jury was required to mitigate any prejudicial effect from the prosecutor's invitation to draw adverse inferences from the played portions.

The legal issues before the High Court included whether the prosecutor was obliged to tender all inculpatory statements, including the full "walk through" video, or at least parts of it. The Court also considered the distinction between directions and comments made by a trial judge in their summing up, and whether the judge's statements amounted to a direction. Furthermore, the Court examined whether a *Jones v Dunkel* direction was required when evidence of blood stains in the appellant's pocket was mentioned by the prosecutor in closing but not put to prosecution witnesses.

The High Court held that there was a failure to give a direction to the jury regarding the use they could not make of the excerpt of the video recording. The commentary provided by the prosecution as to its evidentiary value was considered a wrong decision on a question of law. The Court found that the appellant's participation in the re-enactment involved assertions of fact that were both relevant and admissible as evidence against him, including his presence at the scene and his opportunity to inflict the injuries. While the appellant's explanations during the re-enactment were proffered as exculpatory, the prosecution's selective tendering and invitation to draw adverse inferences from the played portions necessitated a proper direction to the jury.

The High Court allowed the appeal on the ground of the failure to give a proper direction. The Court set aside the order of the Court of Appeal of Western Australia and remitted the matter to that Court for further hearing and disposition, including consideration of whether there had been no substantial miscarriage of justice.
