R v Tran & Tran

In the case of *R v Tran & Tran*, the Court of Criminal Appeal of South Australia considered an appeal by two accused, Minh Tuan Tran (D1) and Ngoc Thai Tran (D2), against their convictions for an aggravated assault. The prosecution alleged that the appellants damaged the victim's vehicle and then physically attacked him, causing serious injuries. D1 presented no evidence, while D2 gave evidence suggesting the victim was the aggressor and that his actions were in self-defence.

The central legal issue before the court was whether the trial judge's directions to the jury concerning the burden of proof and the competing versions of events were adequate. Specifically, the court had to determine if the judge's framing of the case around "the [P] scenario" and "the [D2] scenario," and his comments about which scenario the jury might be "satisfied" occurred, had the effect of improperly shifting the onus of proof from the prosecution to the defence.

The Court of Criminal Appeal found that the trial judge's directions were fundamentally flawed. By referring to the competing accounts as distinct "scenarios" and suggesting that different considerations might apply to being "satisfied" of one scenario over another, the judge risked confusing the jury about the prosecution's sole burden to prove guilt beyond reasonable doubt. The court held that it was impossible to be satisfied that the jury understood this crucial principle, especially given the prominence of these directions within the summing up. Consequently, the court allowed the appeals, quashed the convictions, and ordered a retrial.
