Quach v The Queen

The case of *Quach v The Queen* concerned an appeal to the High Court of Australia by the applicant, Quach, against his conviction for murder. The dispute centred on the admissibility of certain evidence during his trial.

The High Court was required to determine whether the trial judge had erred in admitting evidence that the applicant had remained silent when questioned by police after being cautioned. Specifically, the court had to consider the application of the common law rule against adverse inferences being drawn from an accused's silence, and whether this rule had been abrogated or modified by statute.

The High Court held that the common law rule prohibiting adverse inferences from an accused's silence upon caution remained in force. Their Honours reasoned that the statutory provisions relied upon by the Crown did not expressly or by necessary implication displace this fundamental common law protection. The court emphasised that the right to remain silent is a cornerstone of the criminal justice system, and any departure from this principle must be clearly and unequivocally mandated by Parliament.

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