NSW Commissioner of Police v Cottle & Anor

The New South Wales Commissioner of Police appealed to the High Court of Australia against a decision of the Court of Appeal of the Supreme Court of New South Wales. The appeal concerned the validity of a search warrant issued under the *Crimes Act 1900* (NSW) and the admissibility of evidence obtained pursuant to that warrant. The central dispute revolved around whether the police officer who applied for the warrant had reasonable grounds to believe that the premises to be searched were being used for the commission of a serious indictable offence.

The High Court was required to determine whether the Court of Appeal erred in finding that the police officer lacked reasonable grounds for the belief required to obtain the search warrant. Specifically, the court had to consider the nature and sufficiency of the information presented to the issuing officer to satisfy the statutory threshold for authorising a search. This involved an examination of the evidential basis for the officer's belief concerning the alleged commission of a serious indictable offence.

The High Court held that the Court of Appeal had erred in its assessment of the reasonableness of the police officer's belief. The majority reasoned that the information before the issuing officer, when viewed objectively, provided a sufficient basis for a reasonable belief that the premises were being used for the commission of a serious indictable offence, namely the supply of prohibited drugs. The court emphasised that the standard for reasonable grounds does not require proof beyond reasonable doubt, but rather a reasonable suspicion or belief based on credible information. The Court of Appeal had applied an overly stringent test, effectively requiring a higher degree of certainty than the legislation mandated.

Consequently, the High Court allowed the appeal, set aside the orders of the Court of Appeal, and reinstated the original decision of the primary judge, which had admitted the evidence obtained under the search warrant.
