Cumberland v The Queen

In *Cumberland v The Queen*, the appellant, Cumberland, was convicted of murder and appealed to the Supreme Court of New South Wales. The central dispute concerned the admissibility of evidence obtained through a covert police operation, specifically recordings made by a listening device planted in the appellant's car.

The primary legal issue before the Court was whether the evidence obtained by the listening device was admissible, notwithstanding the fact that the police had not obtained a warrant for its use. This raised questions about the scope of the common law power to admit evidence obtained in contravention of statutory provisions, and the principles governing the exercise of judicial discretion to exclude such evidence.

Bell J considered the relevant provisions of the *Listening Devices Act 1984* (NSW) and the common law principles governing the admissibility of illegally or improperly obtained evidence. His Honour noted that while the Act prohibited the use of listening devices without a warrant, it did not automatically render evidence obtained in contravention of its provisions inadmissible. Instead, the court retained a discretion to admit such evidence if its probative value outweighed any prejudice it might cause. In this instance, Bell J found that the evidence was highly probative of the appellant's guilt and that its prejudicial effect did not warrant its exclusion.

The appeal was dismissed, and the conviction was affirmed.
