Ford v The King

The appeal concerned the admission of evidence obtained from a mobile telephone in the District Court of South Australia. The appellant, Mr Ford, was appealing his conviction. The prosecution sought to admit photographs from the appellant's mobile phone, which included metadata such as dates, times, and GPS information. The defence objected to the admission of this evidence, arguing that there was no expert evidence to explain how the metadata was generated or stored, and that it was unfairly prejudicial.

The primary legal issue before the appellate court was whether the trial judge erred in admitting the mobile phone evidence, including the metadata, without expert testimony. This involved considering whether the absence of expert evidence rendered the admission of the evidence improper, and whether the evidence was unfairly prejudicial to the appellant. The court also considered, though it was not raised at trial, the potential application of provisions within the *Evidence Act 1929* (SA) concerning electronic communications and evidence produced by processes or machines.

The appellate court reasoned that the trial judge was entitled to admit the evidence of what the detectives observed when they accessed the mobile phone. The court held that in the 21st century, expert evidence was not necessarily required to establish that phones record dates and times, and that the absence of such evidence was a matter going to the weight of the evidence, not its admissibility. The court found that the evidence was not more prejudicial than probative and was not unfair to admit. Furthermore, the court noted that even if the *Evidence Act 1929* (SA) provisions regarding electronic communications and processes were considered, they would likely support the admission of the evidence, as they create presumptions of authenticity and accuracy in the absence of evidence to the contrary.

Ultimately, the appellate court concluded that it could not be said that the admission of the mobile phone evidence constituted an error of law or occasioned a miscarriage of justice. Accordingly, the appeal ground concerning the admission of evidence was dismissed, and the appeal itself was dismissed.
