O'Sullivan,R. v

O'Sullivan,R. v

The trial judge fundamentally misdirected the jury by presenting self-defence as the appellant's primary defence and relegating accident (lack of intent) to a secondary position, thereby depriving the appellant of a fair trial. This misdirection rendered the conviction unsafe and required it to be quashed. The evidence supported a conviction under section 20, and the court exercised its power to substitute that conviction.
