R v O'Brien; Williams; McManus [2012] NSWSC 1503

The offenders are equally responsible for manslaughter by unlawful and dangerous act and attempted robbery, having carefully planned to rob the victim, resulting in death during execution of the offence. While none fired the fatal shot or contemplated a weapon's presence, the robbery and potential for harm were within their intention. Sentences imposed reflect parity, seriousness of offending, mitigating personal circumstances, remorse, special circumstances, and a 15% utilitarian discount for guilty pleas.
