DC v The Queen

The Supreme Court of the Northern Territory, Court of Criminal Appeal, heard an appeal by DC against his conviction for an offence against a seven-year-old complainant. The applicant's central argument was that a prosecutor's submission to the jury, suggesting the applicant had a motive to lie due to his interest in the outcome of the trial, constituted a miscarriage of justice unless adequately addressed by the trial judge. This contention raised three key questions for the court's determination: whether the prosecutor's submission was improper, whether the trial judge's directions cured any resulting prejudice, and if not, whether the proviso could be applied.

The court was required to consider whether the prosecutor's submission was improper in inviting the jury to assess the applicant's evidence based on his interest in the trial's outcome. If found to be improper, the court had to determine if the trial judge's directions to the jury were sufficient to mitigate any prejudice caused by such a submission. Finally, if the directions were deemed insufficient, the court needed to assess whether the proviso, which allows an appeal to be dismissed despite a miscarriage of justice if no substantial miscarriage has occurred, could be applied.

The court reasoned that it is improper for a prosecutor to invite a jury to test an accused's evidence solely on the basis of their interest in the outcome of the trial. However, the court found that the trial judge's directions adequately addressed this potential issue, thereby averting a miscarriage of justice. Even if a miscarriage were assumed to have occurred, the court concluded that the proviso could be applied because no substantial miscarriage of justice had occurred, as the record as a whole demonstrated the applicant's guilt beyond a reasonable doubt. Consequently, the appeal was dismissed.
