Kazacos v The Queen

Kazacos v The Queen concerned an appeal to the High Court of Australia following a conviction for conspiracy to import a prohibited substance. The appellant, Kazacos, was convicted in the Supreme Court of Victoria of conspiring with others to import heroin into Australia. The conviction was upheld by the Full Court of the Supreme Court of Victoria, and Kazacos then appealed to the High Court.

The central legal issue before the High Court was whether the trial judge had erred in law by admitting evidence of certain conversations between the appellant and a co-conspirator, which had been obtained by means of an unlawful search. Specifically, the court had to determine whether this evidence, obtained in contravention of the appellant's rights, should have been excluded under the principles governing the admission of illegally or improperly obtained evidence.

Gaudron and McHugh JJ, in their joint judgment, considered the admissibility of evidence obtained in breach of a person's rights. They affirmed the principle that while courts have a discretion to exclude improperly or illegally obtained evidence, this discretion is not absolute. The judges reasoned that the admission of such evidence is permissible where its probative value outweighs any prejudice it might cause to the accused. In this instance, they found that the evidence in question was highly relevant to establishing the conspiracy and that its admission did not occasion a miscarriage of justice.

The appeal was dismissed.
