Leo v The Queen (No 2)

In *Leo v The Queen (No 2)*, the Court of Criminal Appeal of South Australia considered an appeal against a conviction for murder. The appellant, Leo, had been found guilty of murder following a trial.

The central legal issues before the Court of Criminal Appeal were whether the trial judge had erred in law by failing to direct the jury on the defence of provocation, and whether the conviction was otherwise unsafe or unsatisfactory. The appeal also raised questions concerning the admissibility of certain evidence and the adequacy of the summing-up in relation to self-defence.

The Court of Criminal Appeal analysed the evidence presented at trial, particularly concerning the events leading up to the death of the victim. It was held that, while the defence of provocation was not explicitly raised by the defence at trial, there was sufficient evidence from which a jury *could* have inferred that the appellant had acted under provocation. Consequently, the trial judge's failure to direct the jury on this defence was a material error. The Court further found that the conviction was unsafe and unsatisfactory due to this misdirection, as well as other perceived deficiencies in the summing-up.

The Court of Criminal Appeal allowed the appeal, quashed the conviction for murder, and ordered a new trial.
