The Queen v XZ

The case of The Queen v XZ involved a criminal trial where the primary issue was the admissibility of tendency evidence in relation to sexual offences against children. The case was heard in the Supreme Court of Victoria. The defendant argued that the evidence presented had a reasonable possibility of being the result of collusion, concoction, or contamination, and therefore lacked the probative value required for it to be admitted. The court was tasked with determining whether the evidence could be considered reliable and whether there was a reasonable possibility of collusion or concoction that would render it inadmissible.

The legal issues before the court were centered around the admissibility of tendency evidence under the Uniform Evidence Act, specifically whether there was a reasonable possibility of collusion, concoction, or contamination that would undermine the probative value of the evidence. The court had to assess the relationship between the witnesses, the opportunity for contamination, and the motive for concoction. The Crown argued that the evidence only raised a suspicion of collusion and did not meet the threshold for exclusion. The defence contended that the evidence demonstrated a reasonable possibility of collusion or concoction, making it unreliable.

In its reasoning, the court examined the evidence presented, including the Incident Reports, police interviews, and pre-recorded evidence. The court found that while there was some discussion among the witnesses, there was no real possibility of collusion or concoction. The substance of the allegations varied among the witnesses, and there was no motive to concoct stories. The court concluded that the evidence did not fall into the category of inadmissible evidence due to a real possibility of contamination. The court determined that the evidence, while not without some discussion, was sufficiently distinct and varied among the witnesses to be considered reliable.

The court granted leave to recall some witnesses to further clarify certain aspects of the evidence. Ultimately, the court found that there was not a reasonable possibility of collusion or concoction that would render the evidence inadmissible. The court admitted the balance of the evidence, finding it had the necessary probative value to be considered in the trial. The court's final orders included the admission of the contested evidence, subject to the court's findings on the probative value and potential contamination.
