Subramaniam v The Queen

The High Court of Australia heard an appeal from the New South Wales Court of Criminal Appeal concerning charges of perverting the course of justice against the appellant. The dispute arose from the appellant making a statutory declaration falsely identifying herself as the driver of a vehicle that had run a red light, with the intention of perverting the course of justice. The appellant was subsequently charged with making a false statutory declaration and giving false evidence. The core of the appeal concerned whether a "special hearing" conducted under the *Mental Health (Criminal Procedure) Act 1990* (NSW) should have been stayed, and whether the hearing was conducted in compliance with the Act.

The legal issues before the High Court included whether the trial judge erred in refusing to grant a stay of proceedings, considering the appellant's mental unfitness to stand trial. The court also had to determine if the special hearing was conducted in accordance with the procedural requirements of the *Mental Health (Criminal Procedure) Act 1990* (NSW), particularly regarding the adequacy of the trial judge's directions to the jury concerning the appellant's absence from giving evidence and the handling of certain recorded and oral evidence. A further issue was whether the prosecution had a duty to present more detailed evidence regarding the appellant's mental health to the jury.

The High Court allowed the appeal, quashing the appellant's conviction and ordering a new trial. The Court found that the trial judge had failed to comply with section 21(4) of the *Mental Health (Criminal Procedure) Act 1990* (NSW), which mandates that a judge must be satisfied that the accused is capable of understanding the proceedings and is capable of communicating with their legal representative. The Court held that the evidence before the trial judge was insufficient to establish these matters, particularly given the appellant's diagnosed mental health issues. The Court also noted that the trial judge's directions to the jury regarding the appellant's unfitness to be tried and the handling of evidence were inadequate.
