Viro v The Queen [1978] HCA 9

Viro v The Queen [1978] HCA 9

The High Court is no longer bound by Privy Council decisions. The jury should have been directed to consider the effect of drug intoxication (heroin) on the formation of intent for murder. Failure to give this direction was a miscarriage of justice requiring a new trial. If self-defence is raised and fails only because excessive force was used, the proper verdict is manslaughter, following Reg. v. Howe.

Ratio Decidendi
