Rigby v Mulhall

In the case of Rigby v Mulhall, the appellant sought to appeal a decision made in the Local Court, which had dismissed his challenge to the admissibility of evidence obtained during a search of his vehicle. The search, conducted under section 120C of the Police Administration Act 1978 (NT), was predicated on the police having reasonable grounds to suspect the presence of a dangerous drug. However, the search yielded a prohibited weapon rather than a drug, leading to a challenge regarding the legality of the search. The appellant contended that the police did not have sufficient grounds to reasonably suspect the presence of a dangerous drug, and thus the search was unlawful.

The legal issues before the court centred on the interpretation and application of section 120C of the Police Administration Act 1978 (NT). The primary question was whether the information upon which the police based their suspicion was adequate to meet the threshold of "reasonable suspicion". The court was also required to determine if the evidence obtained from the search, which was a prohibited weapon, could be admitted in court given the alleged unlawfulness of the search.

The court examined the threshold of "reasonable suspicion" and found that the information relied upon by the police did not objectively support a suspicion that a dangerous drug was present. The court held that the police's suspicion was not based on sufficient grounds to justify the search under section 120C. As a result, the search was deemed unlawful, and the evidence obtained as a consequence of the search was inadmissible. The court did not find any error of law in the Local Court's decision but affirmed that the evidence obtained from the unlawful search was indeed unlawful. Consequently, the appeal was dismissed.

In light of the findings, the court did not make any further orders beyond dismissing the appeal. The decision underscores the necessity for police to have objectively sufficient grounds to reasonably suspect the presence of a dangerous drug to justify a search without a warrant under section 120C of the Police Administration Act 1978 (NT).
