Stanley v. Director of Public Prosecutions (NSW)

Stanley v. Director of Public Prosecutions (NSW) is a significant Australian legal case concerning the admissibility of evidence obtained through illegal or improper means. Specifically, it addresses the application of judicial discretion to exclude such evidence, even if it is relevant, in criminal proceedings.

The case primarily revolves around Section 138 of the Evidence Act 1995 (NSW), which allows a court to refuse to admit evidence if the way in which it was obtained was unlawful or improper, and the desirability of admitting the evidence is outweighed by the undesirability of admitting evidence that has been obtained in that way.

Key factors considered by the court in exercising this discretion include:

• The seriousness of the impropriety or contravention: How egregious was the conduct by law enforcement in obtaining the evidence?
• The seriousness of the offence: The more serious the alleged offence, the greater the public interest in having the matter determined on its merits.
• Whether the impropriety or contravention was deliberate or reckless: Evidence obtained intentionally through unlawful means is viewed more unfavourably than evidence obtained through unintentional error.
• The ease with which the law could have been complied with: Was it easily possible for law enforcement to have followed correct procedures?
• The existence of any alternative means of obtaining the evidence: Did the police have other lawful avenues to obtain the same evidence?
• The impact on the accused: The potential impact on the fairness of the trial and the integrity of the judicial system.

The Stanley case emphasizes that the discretion to exclude illegally or improperly obtained evidence is not to be exercised lightly. Courts must carefully balance the public interest in the conviction of offenders with the need to ensure that law enforcement operates within the bounds of the law and that the integrity of the judicial process is maintained. The case serves as an important precedent for determining the admissibility of evidence obtained in questionable circumstances in New South Wales and provides guidance applicable to similar legislation in other Australian jurisdictions.
