Hibble v B

In the matter of Hibble v B, the respondent, a 13-year-old child, challenged the admissibility of a DNA sample obtained from him during a police investigation. The sample was voluntarily provided but the retention and processing of the sample did not comply with the relevant statutory provisions. The matter was heard in the Supreme Court of Victoria. The central issue before the court was whether the DNA sample, obtained from the respondent without proper authorisation, should be excluded from evidence under the discretionary powers available to the court. Specifically, the court needed to consider whether the breach of the Forensic Procedures Act 2000 was serious enough to warrant exclusion of the evidence.

The court examined the provisions of the Forensic Procedures Act 2000, which requires that a DNA sample can only be taken from a person if certain conditions are met, including an agreement with the Commissioner of Police regarding the period for retaining the sample. In this case, the sample was taken without such an agreement and there was no delegated authority to take the sample. The court needed to weigh the gravity of the contravention against the public interest in obtaining and using the evidence. The court held that the breach was serious and the gravity of the contravention was significant enough to warrant the exclusion of the DNA evidence. The court found that the breach was not trivial and had a substantial impact on the integrity of the investigation.

The Supreme Court of Victoria exercised its discretion to exclude the DNA evidence, given the breach of statutory provisions and the absence of a proper agreement with the Commissioner of Police. The court determined that the exclusion of the evidence was necessary to uphold the integrity of the judicial process and to ensure that the rights of the respondent were protected. The court's decision was based on a careful assessment of the statutory framework and the specific circumstances of the case, leading to the exclusion of the DNA evidence from the trial.
