Glass v Tasmania

The Supreme Court of Tasmania, Court of Criminal Appeal, heard an appeal by the appellant, Glass, against his conviction and sentence. The dispute concerned allegations of criminal conduct, and the appeal was brought on the grounds of a miscarriage of justice.

The central legal issues before the Court were whether the trial judge had failed to adequately direct the jury on the potential unreliability of certain evidence, and whether the judge had erred by not providing sufficient directions regarding the permissible use of evidence relating to the appellant's uncharged criminal and discreditable conduct. Specifically, the Court considered whether the jury had been properly cautioned against engaging in impermissible propensity or tendency reasoning.

The Court found that the trial judge's directions to the jury were insufficient, constituting a miscarriage of justice. The failure to provide adequate warnings about the potential unreliability of key evidence, and the lack of clear guidance on how evidence of uncharged conduct could and could not be used, meant that the jury may have been led to make impermissible inferences about the appellant's character and propensity to commit the offences charged. This amounted to a failure to ensure a fair trial.

Consequently, the Court allowed the appeal, quashed the appellant's conviction and sentence, and ordered that the appellant be retried on the indictment, with the decision to proceed with a retrial resting with the Director of Public Prosecutions.
