R v MacDonald

The appellant, Damian Harley MacDonald, appealed against his conviction of murder by the High Court at Nelson. MacDonald was convicted following a jury trial, which included his testimony that he believed the deceased, Mr Winter, was an assailant. The appeal hinged on whether the trial judge failed to provide a tripartite direction to the jury regarding MacDonald's evidence. The tripartite direction, approved by the Court of Appeal of New Zealand in R v McI, instructs the jury to acquit if they accept the accused's evidence on key issues, consider acquitting if there is a reasonable possibility the accused's evidence might be true, and examine all evidence to decide if the accused's guilt is established beyond reasonable doubt if they reject the accused's evidence. MacDonald's counsel argued that the omission of the tripartite direction was a significant error, as it did not account for the possibility of rejecting MacDonald's account without accepting the Crown's case. In contrast, the Crown contended that the trial judge's directions adequately conveyed the standard of proof and the jury's consideration of the evidence. The Court of Appeal held that the absence of a tripartite direction did not lead to a miscarriage of justice, as the trial judge's directions were comprehensive and tied to the evidence presented. The Court found that a general tripartite direction would have been inappropriate and potentially confusing in this case, particularly regarding the defence of self-defence and the issue of intoxication. The appeal was dismissed, and MacDonald's conviction of murder was upheld.
