Jeffers v R

In *Jeffers v R*, the High Court of Australia considered an appeal by the applicant, Jeffers, against his conviction for murder. The central dispute concerned the admissibility of certain evidence obtained during police investigations.

The High Court was required to determine whether the trial judge had erred in admitting evidence that was obtained in circumstances where the applicant had been subjected to oppressive and unfair treatment by police. Specifically, the court had to consider the application of the principle that evidence obtained unfairly or oppressively should be excluded, even if it is relevant and otherwise admissible.

The Court held that the evidence in question had been obtained in circumstances that were oppressive and unfair, and therefore should have been excluded from the trial. The judges applied the principle that the court has a discretion to exclude evidence if its prejudicial effect outweighs its probative value, and that this discretion extends to evidence obtained unfairly or oppressively. In this instance, the oppressive conduct of the police in obtaining the evidence was found to be so significant that it rendered the evidence inadmissible.

The High Court allowed the appeal, quashed the conviction, and ordered a new trial.
