R v Grills

The case of R v Grills involved an appeal to the High Court of Australia from a decision of the Supreme Court of New South Wales. The appeal concerned the conviction of a prisoner for an unnatural offence upon a boy. The central dispute revolved around the admissibility and proper direction to the jury regarding evidence of a conversation that occurred between the arresting constable, the boy, and the prisoner before the prisoner's arrest. In this conversation, the boy accused the prisoner of the offence, and the prisoner asserted his innocence.

The legal issues before the High Court were whether the evidence of the statements made in the prisoner's presence, and subsequently denied by him, was properly admitted, and whether the trial judge's summing-up to the jury constituted a sufficient direction regarding this evidence. Specifically, the question arose whether the jury should have been explicitly directed that statements made in the prisoner's presence, which he denied, were not evidence of his guilt.

A majority of the High Court, comprising Griffith C.J., Barton J., and O'Connor J., held that the evidence of the statements made in the prisoner's presence was properly admitted. They reasoned that while such statements are not independent evidence of guilt if denied, they can be relevant to the accused's conduct. The majority concluded that, in the specific circumstances of this case, the trial judge's direction to the jury, which focused on the conflict between the boy's sworn evidence and the prisoner's denial and left the ultimate belief to the jury, was sufficient. Griffith C.J. articulated a principle that a caution to the jury is only necessary if the circumstances suggest a danger that the jury might treat the statement as independent evidence of the facts alleged; otherwise, such a caution is unnecessary. Isaacs J. dissented.

The High Court allowed the appeal, setting aside the decision of the Supreme Court of New South Wales and restoring the prisoner's conviction. The Supreme Court had previously quashed the conviction on the ground that the jury should have been more explicitly directed regarding the statements made in the prisoner's presence and denied by him.
