REGINA v William Harold MATHESON [2006] NSWSC 332

REGINA v William Harold MATHESON [2006] NSWSC 332

The murder was premeditated, planned, brutal and cruel, placing it above the middle range of objective seriousness for murder. The offender's psychiatric condition had little causative effect on the killing and only minor ameliorating effect, although it remained relevant to risk, treatment and supervision. His youth, prior good character, mental disorder, protective custody conditions and need for lifelong medication justified a significant reduction from what otherwise would have been imposed and constituted special circumstances, resulting in a non-parole period of eighteen years and a total sentence of twenty-seven years.

Criminal Sentence for Murder / Sentencing After Jury Verdict of Guilty

Legal Issues

  1. 1 ["What sentence should be imposed for the offender's murder of Lyndsay Van Blanken." 'Whether the murder was above the middle range of objective seriousness for murder.' "What effect, if any, the offender's psychiatric condition should have on sentence."
