R v Cahill (No. 3)

The case involved the third trial of a defendant, Cahill, who was accused of murder. The matter came before the High Court, which had to consider various pretrial rulings regarding the admissibility of evidence in the case. The court was tasked with determining the correct application of Section 65 of the Evidence Act 1995, which addresses the admissibility of evidence obtained in contravention of the law. The rulings made by the lower courts on these issues were under scrutiny.

The primary legal issue before the court was whether the lower courts had correctly applied Section 65 of the Evidence Act 1995 in their determinations about the admissibility of evidence in Cahill's trial. Specifically, the court had to consider whether the evidence obtained through certain investigative procedures should be excluded because it was obtained in a manner that contravened the law. The focus was on whether the lower courts had correctly balanced the prejudicial effect of the evidence against its probative value, and whether they had adequately considered the principles of justice and fairness in their rulings.

The court found that the lower courts had not correctly applied the provisions of Section 65 of the Evidence Act 1995. They held that the lower courts had failed to sufficiently weigh the prejudicial effect of the evidence against its probative value and had not adequately considered the principles of justice and fairness. The court emphasised that when making rulings on the admissibility of evidence obtained in contravention of the law, it is essential to strike a balance between the need to prevent the use of evidence obtained in an unlawful manner and the risk of unfairly prejudicing the accused. The court concluded that the lower courts had erred in their approach and that the evidence should have been admitted, given the circumstances of the case. The High Court made orders to this effect, directing the lower courts to reconsider the admissibility of the evidence in light of their ruling.
