Regina v Dalton

In Regina v Dalton, the accused was charged with incitement to murder after he was induced to speak to an undercover police officer. The central issue before the court was whether the officer's actions in encouraging the accused to commit the offence constituted a breach of the law, and if so, whether the conversation between the accused and the officer should be deemed inadmissible due to the officer's involvement. The court was also required to consider the discretionary considerations under the Law Enforcement (Controlled Operations) Act 1997 in relation to the admissibility of the evidence.

The court considered the nature of the controlled operation and the officer's conduct in relation to the incitement. It was determined that the officer's actions did not constitute an offence, as they were necessary to prevent the commission of a serious crime. However, the court found that the conversation between the accused and the officer was inadmissible as evidence due to the officer's involvement in encouraging the commission of the offence. The court applied the discretionary considerations under the Act, taking into account the nature and seriousness of the offence, the manner in which the evidence was obtained, and the potential impact on the fairness of the trial.

The court concluded that the admission of the evidence would undermine the fairness of the trial, and thus, it was in the interests of justice to exclude the conversation between the accused and the officer. The accused's appeal against conviction was dismissed, but the conviction was quashed and a retrial was ordered due to the exclusion of the evidence. The court emphasised the importance of maintaining the integrity of the criminal justice system and the need to ensure that evidence obtained through improper means does not prejudice the accused's right to a fair trial.
