R v Stephen (No. 5)

The case before the court involved a defendant charged with manslaughter, where the primary issue was whether the jury should be given a specific direction on the application of the "second leg" of the self-defence principle. The defendant sought a Prasad direction to assist the jury in understanding the complexities involved in the evaluation of self-defence in the context of the particular circumstances of the case. The High Court of Australia was tasked with determining whether such a direction was appropriate under the circumstances presented.

The court was required to decide whether the judge should provide an additional direction to the jury concerning the "second leg" of the self-defence principle. This principle involves the evaluation of whether the defendant's response was reasonable in the circumstances. The defendant argued that the jury required a detailed explanation due to the complexity of the legal issues involved. The prosecution contended that the existing directions were sufficient and that the matter should be left to the evaluative judgment of the jury.

In reaching its decision, the court considered the principles of self-defence and the role of the jury in assessing such matters. The court concluded that while the "second leg" of self-defence involved a complex evaluation, it was ultimately an evaluative judgment for the jury to make. The court held that the trial judge had already provided adequate directions to the jury on the matter, and that further explanation would not necessarily aid in the jury's understanding. Therefore, the court rejected the application for a Prasad direction.
