George v Rockett

The High Court of Australia considered the appeal in *George v Rockett*. The case concerned a prosecution for the unlawful possession of a prohibited substance, specifically cannabis, under the *Misuse of Drugs Act 1981* (SA). The appellant, George, was found to be in possession of cannabis, and the central dispute revolved around whether he had knowledge of its presence.

The primary legal issue before the High Court was whether the prosecution was required to prove that the appellant had actual knowledge of the presence of the prohibited substance, or whether constructive knowledge or a lack of reasonable belief to the contrary was sufficient. This question arose in the context of the statutory offence, which did not explicitly define the mental element required for possession.

The Court held that the offence of possession under the *Misuse of Drugs Act 1981* (SA) required proof of knowledge of the existence of the prohibited substance. However, this knowledge could be established by inference from the surrounding circumstances. The Court rejected the argument that the prosecution needed to prove actual knowledge, finding that it was sufficient to prove that the accused knew of the existence of the substance or was wilfully blind to its existence. The principle applied was that possession requires a physical control coupled with an intention to exercise that control, and this intention is predicated on knowledge of what is being controlled.

The appeal was dismissed, with the High Court upholding the conviction.
