Kalbasi v Western Australia

The High Court of Australia considered an appeal by Mr Kalbasi against a conviction for attempting to possess a prohibited drug with intent to sell or supply. The dispute arose from the trial judge's directions to the jury, which erroneously assumed that proof of possession of a substitute substance would suffice to prove the appellant's intention to sell or supply. This assumption stemmed from a misinterpretation of section 11 of the Misuse of Drugs Act 1981 (WA), leading to a situation where the crucial element of intent was effectively removed from the jury's consideration.

The central legal issue before the High Court was whether a substantial miscarriage of justice had occurred, thereby precluding the application of the statutory proviso (s 30(4) of the Criminal Appeals Act). This involved determining if the erroneous direction regarding the intention to sell or supply, coupled with the jury's focus solely on the appellant's possession of the substitute substance, deprived the appellant of a fair chance of acquittal. The Court was required to assess whether the trial had, in substance, proceeded on the basis of a different offence than that for which the appellant was indicted.

The Court reasoned that a substantial miscarriage of justice occurs when an accused is not truly tried for the offence for which they were indicted. In this case, the trial judge's direction, based on a mistaken understanding of the law and an incorrect concession by counsel, removed the element of intent to sell or supply from the jury's purview. This meant the jury was not tasked with determining guilt for the charged offence, but rather for a lesser offence. Despite the strong circumstantial evidence presented by the prosecution, the Court concluded that it was open for a jury, properly directed, to reach a contrary conclusion regarding the appellant's guilt. Therefore, the erroneous direction constituted a fundamental error and a serious departure from the requirements of a fair trial.

Consequently, the High Court allowed the appeal, quashed the conviction, set aside the sentence, and ordered a new trial.
