Kometer v The State of Western Australia

In this case, the appellant, Kometer, appealed against his conviction for criminal offences, contending that the trial had miscarried due to the admission of inadmissible hearsay and opinion evidence. The decision was handed down by the Supreme Court of Western Australia. The respondent, the State of Western Australia, defended the trial's integrity and argued that the appellant's failure to object to the evidence was a rational forensic decision.

The court had to determine whether the trial was fundamentally flawed due to the alleged inadmissible evidence and whether the trial judge could have reasonably concluded that the failure to object was a strategic decision. The court examined the nature and impact of the evidence in question, considering whether it was so prejudicial that it rendered the trial unfair. Additionally, the court assessed the appellant's reasons for not objecting to the evidence, including the potential impact on the trial's outcome and the legal advice received.

The court found that while some of the evidence was indeed inadmissible, it did not reach the threshold of prejudice that would render the trial unfair. The court held that the appellant's failure to object could be seen as a rational strategic decision, considering the potential consequences of an objection. The appeal was dismissed as the court was satisfied that the trial was conducted fairly and that the appellant's rights were not prejudiced. The court emphasised the importance of strategic decisions in the context of trial proceedings and the discretion of the trial judge in managing the flow of evidence.
