R v PERCY

The appeal before Vanstone, Anderson and Stanley JJ of the Supreme Court of South Australia concerned a conviction for attempted aggravated robbery, with the aggravating factor being the use of an offensive weapon. The appellant argued that the jury's verdict was unreasonable and could not be supported by the evidence presented at trial, which relied heavily on circumstantial evidence to establish the appellant's identity as the offender.

The central legal issue before the court was whether it was open to the jury to be satisfied of the appellant's guilt beyond reasonable doubt, or conversely, whether the jury must have entertained a doubt about the appellant's guilt. This required the court to consider the weight and sufficiency of the circumstantial evidence, including DNA found on items left at the scene and the appellant's possession of a firearm.

The court reasoned that while some pieces of circumstantial evidence, such as a hat and glove, were of little weight, the DNA evidence found on a pillow case and a shopping bag, coupled with the appellant's possession of a gun and a general description of the offender that did not exclude the appellant, provided a sufficient basis for the jury's verdict. Applying the principles established in *M v R* and *Libke v R*, the court held that it was not possible to say that the jury must have entertained a reasonable doubt about the appellant's guilt. The jury had the primary responsibility of determining guilt and had the benefit of seeing and hearing the witnesses.

Consequently, the appeal was dismissed, as it was open to the jury to be satisfied of the appellant's guilt beyond reasonable doubt based on the totality of the circumstantial evidence presented.
