Criminal law – Assisting offender. The Supreme Court allowed the appellant's appeal against conviction for murder, in circumstances where the appellant had allegedly assisted or encouraged another person to commit a murder. The court held that the principle regarding encouragement and assistance expressed in the case of Chan Wing-Siu v R (see[1984] 3 All ER 877) had been wrong. It invited written submissions as to whether to quash the appellant's conviction and order a re-trial, or to quash the conviction and substitute a conviction for manslaughter.
