Diab v The King

In the matter of Diab v The King, the High Court of Australia considered the appeal of the applicant, Diab, against his conviction for discharging a firearm in a manner that was reckless as to the safety of police officers. Diab had discharged a firearm at night shortly after the arrival of an unmarked police vehicle. The legal issues before the Court were whether the prosecutor's argument, unsupported by evidence, could be redressed by a direction from the trial judge, and whether the verdicts were unreasonable or unsupported by the evidence. The Court also considered whether it was open to the jury to conclude that Diab had heard and understood the police identification.

The Court held that the trial judge's direction to the jury was insufficient to redress the unsupported argument advanced by the prosecutor. The argument that Diab had fired three shots was inconsistent with the evidence presented, and the prejudice caused by this argument could not be sufficiently dispelled by the judge's direction. The Court found that the verdicts were unreasonable or unsupported by the evidence, as the jury's conclusion that Diab had fired three shots was not consistent with the direct evidence. The Court also held that it was open to the jury to conclude that Diab had heard and understood the police identification, based on the circumstances of the case.

As a result of the Court's decision, Diab's convictions for discharging a firearm being reckless as to the safety of police officers were quashed. However, he was convicted on the alternative charge of discharging a weapon at a vehicle, in contravention of s 131A(1) of the Firearms Act 1996. The Court's decision highlights the importance of ensuring that arguments presented to the jury are supported by evidence, and that any unsupported arguments are sufficiently redressed by the trial judge's directions. It also underscores the need for careful consideration of the circumstances of each case, in determining whether it was open to the jury to draw certain inferences.
