Miller v The Queen

In *Miller v The Queen*, the High Court of Australia considered an appeal from a judgment of the Court of Criminal Appeal of Queensland. The appellant, Miller, had been convicted of a number of offences, including unlawful use of a motor vehicle and dangerous operation of a motor vehicle causing death. The central dispute concerned the admissibility of evidence obtained from the appellant's mobile phone, which had been seized by police.

The High Court was required to determine whether the evidence obtained from the appellant's mobile phone was admissible, notwithstanding that the search of the phone was conducted without a warrant and arguably without sufficient lawful justification at the time of seizure. Specifically, the Court had to consider the application of the exclusionary rule and the principles governing the admission of improperly or illegally obtained evidence in criminal proceedings.

The Court reasoned that the admission of evidence obtained in contravention of a person's rights, even if illegally obtained, is not automatically prohibited. Instead, the court must exercise a discretion to admit such evidence. This discretion involves a balancing exercise, weighing the probative value of the evidence against the degree of culpability of the law enforcement officers in obtaining it, and considering the potential prejudice to the accused. In this instance, the High Court found that the trial judge had erred in admitting the evidence without adequately considering the relevant discretionary factors, particularly the impact on the fairness of the trial.

Consequently, the High Court allowed the appeal, quashed the conviction, and remitted the matter to the Court of Criminal Appeal of Queensland for a retrial.
