O'Connell v Director of Public Prosecutions

The appeal concerned a conviction for murder, brought before the Court of Criminal Appeal of New South Wales by the appellant, O'Connell, against the Director of Public Prosecutions. The central dispute revolved around whether the jury's verdict was unreasonable or unsupported by the evidence, and whether a miscarriage of justice had occurred during the trial.

The Court was required to determine several key legal issues. These included whether the prosecutor's closing address had resulted in a miscarriage of justice, and similarly, whether the trial judge's failure to direct the jury on the meaning of "probability" constituted a miscarriage of justice. Further, the Court considered whether a miscarriage of justice arose from the trial judge's omission to remind the jury of other evidence when a recording of the principal prosecution witness's testimony was replayed. Finally, the Court had to assess whether the jury ought to have entertained a doubt regarding the requisite mental element of reckless indifference to human life.

The Court allowed the appeal, setting aside the verdict of guilty of murder and the sentence imposed. It ordered a verdict of not guilty of murder, reserving the question of whether another verdict should be entered.
