HT v The Queen

The High Court of Australia considered an appeal by HT against a decision of the Court of Criminal Appeal of New South Wales. The dispute arose from a Crown appeal against a sentence imposed on HT, where the sentencing court was statutorily required to take into account assistance HT had provided to law enforcement authorities. Crucially, evidence of this assistance was kept confidential from HT and their legal representatives during the sentencing proceedings due to its highly sensitive criminal intelligence nature.

The central legal issues before the High Court were whether HT had been denied procedural fairness, whether the Court of Criminal Appeal possessed the power to deny HT access to the confidential evidence, and whether the Court of Criminal Appeal should have declined to exercise its discretion to re-sentence HT. These issues revolved around the tension between the principles of open justice and procedural fairness on the one hand, and the protection of confidential information and public interest immunity on the other.

The High Court reasoned that the denial of access to the evidence of assistance, which was a critical factor in sentencing, fundamentally undermined procedural fairness. While acknowledging the importance of protecting sensitive information, the Court held that the Court of Criminal Appeal had erred in denying HT access to the evidence. The Court found that the Court of Criminal Appeal should not have exercised its discretion to re-sentence HT in the absence of proper disclosure and an opportunity for HT to respond to the confidential material. Consequently, the High Court allowed the appeal, setting aside the orders of the Court of Criminal Appeal and ordering that the Crown appeal be dismissed. The Court also made orders suppressing the contents of Exhibit C to protect the administration of justice and the safety of individuals.
