Marshall v The King

The appellant, Jackson Nathanial Jai Marshall, appealed his conviction for aggravated robbery, which was returned by a jury in the Supreme Court of the Australian Capital Territory. The Crown case alleged that the appellant, along with at least one other person, approached the victim, threatened him with a knife, and stole his belongings, including a vehicle. The central issue at trial was the identification of the appellant as the assailant, as there was no dispute that a robbery had occurred.

The appellant raised five grounds of appeal. These included claims that the jury's verdict was unreasonable, that the trial judge erred in admitting identification evidence derived from a Facebook photograph, that the judge wrongly admitted a photograph of an individual known as "Sugi" for comparison, that evidence of consciousness of guilt from the deletion of online messages was improperly admitted, and that a miscarriage of justice occurred due to the calling of three specific witnesses. The appeal court noted that there was no challenge to the correctness or adequacy of the jury directions.

The Court of Appeal dismissed the appeal. It reasoned that the Crown's case was circumstantial, relying on multiple strands of evidence. These included the appellant's presence in the vicinity of the robbery, descriptions of the offender consistent with the appellant's appearance, the victim's identification of the appellant's Facebook photograph, witness sightings of the stolen vehicle, forensic evidence linking the appellant to the vehicle, and evidence of association with other individuals linked to the vehicles. The court found that the trial judge had not erred in admitting the challenged evidence and that the cumulative effect of the evidence was sufficient to support the jury's verdict, thus no miscarriage of justice had occurred.
