Gemmill v The Queen

Gemmill appealed his conviction for armed robbery and the sentence imposed by the Supreme Court of Victoria. The appeal concerned the admissibility of certain evidence and the severity of the sentence.

The High Court was required to determine whether the trial judge erred in admitting evidence obtained from the appellant's mobile phone, specifically call records and location data, without a warrant. It also had to consider whether the sentence imposed was manifestly excessive, having regard to the appellant's personal circumstances and the nature of the offence.

The Court held that the admission of the mobile phone data was lawful, as it was obtained in circumstances where the police had reasonable grounds to suspect the appellant was involved in criminal activity, and the data was relevant to the investigation. The Court further found that the sentence of 10 years imprisonment with a non-parole period of 7 years was not manifestly excessive, given the seriousness of the armed robbery, the use of a weapon, and the appellant's prior criminal record.

The appeal was dismissed.
