Kroni v The Queen

The Supreme Court of South Australia, constituted by Kourakis CJ, Doyle and Livesey JJ, heard an appeal by the appellant, Mr. Kroni, against his conviction for trafficking in a controlled drug. The appellant did not dispute possession of 27.1 grams of cocaine but denied any intention to sell it. Due to a statutory presumption of sale under the Controlled Substances Act 1984 (SA), the onus was on the appellant to prove, on the balance of probabilities, that his possession was not for the purpose of sale, making the appellant's intent the sole issue at trial. The appellant also sought permission to appeal against his sentence of four years' imprisonment with a non-parole period of 20 months.

The legal issues before the court included whether the trial judge erred in her directions regarding the permissible and impermissible use of evidence of discreditable conduct, whether she provided adequate reasons for finding the appellant failed to displace the statutory presumption of sale, and whether she misdirected herself concerning the credibility of the appellant's domestic partner and the appellant himself, potentially leading to a miscarriage of justice. The court also considered the application of the proviso in criminal appeals, which allows an appeal to be dismissed if, despite an error, there has been no substantial miscarriage of justice.

The court reasoned that evidence of discreditable conduct, such as the significant amount of cash, multiple mobile phones, and a heat sealing machine found in the appellant's possession and at his home, was admissible as circumstantial evidence probative of involvement in a drug trading enterprise. This evidence, in conjunction with the possession of cocaine, could support an inference of intent to sell, as recognised by established authorities. The court found that any failure by the trial judge to extend directions regarding the cash to other evidence of discreditable conduct did not affect her assessment of the evidence or her conclusion of guilt. The court was satisfied that the appellant did not lose any chance of a fair acquittal and therefore applied the proviso to dismiss the appeal against conviction. The appeal against sentence was also dismissed.
