R v Heffernan; R v Stephens

Appeals were brought before the Court of Appeal of Victoria by two defendants, Heffernan and Stephens, following their convictions for murder after a jury trial. The central dispute on appeal concerned the adequacy of the trial judge's directions to the jury regarding the defence of self-defence, which Heffernan had raised. Stephens, who claimed to have acted in aid of Heffernan, argued he was entitled to rely on Heffernan's defence. Stephens also raised a separate ground of appeal concerning the judge's directions on the significance of an out-of-court inconsistent statement made by a prosecution witness.

The legal issues before the court were whether the trial judge erred in his directions on self-defence, specifically concerning the concept of reasonable proportionality, and whether his subsequent redirection on this defence introduced a risk of miscarriage of justice. Additionally, the court considered whether Stephens' appeal was prejudiced by the judge's failure to adequately direct the jury on the significance of a prior inconsistent statement made by a prosecution witness, Ms Shamroze-Hanson.

The Court of Appeal, in dismissing the appeals, held that the jury had been correctly directed on self-defence at the outset. The court found no real risk that the jury misunderstood the requirement of "reasonably proportionate" force when the judge used the term "proportionate," viewing it as a shorthand reference to the earlier, comprehensive direction. Regarding the inconsistent statement, the court acknowledged that while it would have been preferable for the judge to have drawn the jury's attention to the inconsistency and its relevance, the circumstances of the trial meant this omission did not constitute an error of law or render the verdict unsafe. The jury would have been aware of the challenge to Ms Shamroze-Hanson's credibility and reliability, particularly given the emphasis during cross-examination and final addresses, and the judge had cautioned the jury to scrutinise the evidence of witnesses who had consumed alcohol and drugs.
