XZ v The Queen

The matter before the court was an appeal against a decision to allow evidence of the appellant’s willingness to provide information to the Australian Federal Police about persons involved in drug trafficking. The appellant sought to appeal the decision of a single judge of the Federal Court of Australia who had refused to quash an order for the publication of certain evidence. The appellant argued that such publication would put their life at risk, particularly given the nature of the evidence which tended to identify them as a person willing to assist law enforcement agencies.

The legal issues before the court were whether the single judge had erred in law by not quashing the order for the publication of evidence that tended to identify the appellant as a person willing to provide information to the Australian Federal Police about persons involved in drug trafficking. The court needed to determine whether such evidence was relevant and whether it was necessary to publish the evidence to ensure the administration of justice. The appellant argued that the evidence was irrelevant and that its publication would put their life at risk, which outweighed the need to publish the evidence for the administration of justice.

The court found that the single judge had erred in law in not quashing the order for the publication of evidence. The court held that the evidence was not relevant and that the appellant had demonstrated a real risk to their life if the evidence was published. The court found that the risk to the appellant’s life was such that it outweighed the need to publish the evidence to ensure the administration of justice. The court also found that the appellant had made out a real risk to their life, which was sufficient to warrant the quashing of the order for the publication of evidence. The court granted the application for leave to appeal, allowed the appeal, and forbade the publication of evidence identifying or tending to identify the appellant as being prepared to assist the Australian Federal Police by providing information concerning any person involved in drug trafficking, as well as the identity of any such person.
