Assault & violencePublic order & justice offences

Citation: R v Jeffrey John Mason [2009] NSWDC 364
Court: District Court of New South Wales
Date: 3 November 2009
Judge(s): Berman SC DCJ


Background

The offender, a 34-year-old man with a long history of paranoid schizophrenia, pleaded guilty in the Local Court to aggravated break, enter and commit a serious indictable offence. The serious indictable offence was an assault occasioning actual bodily harm upon his neighbour. The circumstance of aggravation charged was that the offender maliciously inflicted actual bodily harm, though the court noted other aggravating features were also present.

On 1 January 2009, in the early hours of the morning, the offender cut through a screen door and entered his neighbour's flat armed with a metal pole. He struck the sleeping victim multiple times, causing serious lacerations to the wrist, elbow, upper arm and head, with tendons visible through some wounds.

In the lead-up to the attack, the offender had deceived his community mental health crisis team by telling them he was coping well and experiencing no fits of rage. As a result, his antipsychotic injections were discontinued. His condition deteriorated and, driven by paranoid beliefs about the victim, he carried out the assault. A psychiatrist, Dr Westmore, concluded that the offender's mental illness was the prime factor behind the attack.


  • What sentence was appropriate for aggravated break, enter and commit a serious indictable offence, taking into account the offender's mental illness and guilty plea?
  • Whether the objective seriousness of the offence was above or below the midpoint for its category, given the available standard non-parole period as a guidepost?
  • Whether special circumstances existed justifying a non-parole period shorter than the statutory default ratio, so as to extend the period of parole supervision?
  • What weight should be given to general deterrence versus personal deterrence where an offender's mental illness substantially explains the offending?

Decision

Berman SC DCJ found the objective gravity of the offence was significantly above the midpoint for offences of this type. The assault took place in the victim's home while he was asleep and vulnerable, the harm was serious, and the offender was armed. The court also noted that circumstances of aggravation beyond those formally charged by the Crown were present, including the offender's knowledge that the victim was home and his use of a weapon.

Notwithstanding the objective seriousness, the court reduced the weight given to general deterrence because of the offender's diagnosed mental illness. The court accepted that personal deterrence retained some relevance: the offender needed to understand the consequences of future serious offending. The 25 per cent discount for the utilitarian value of the guilty plea entered in the Local Court was applied.

The court found special circumstances, departing from the standard ratio between the non-parole period and the head sentence. The principal reason was the offender's need for an extended period of supervised parole to support compliance with his medication and treatment regime, and to assist his rehabilitation from drug use. The court expressly recommended to the Parole Board that conditions of parole address compliance with prescribed medication and treatment.

The court also noted the offender's limited criminal history, which contained no prior violence, and observed that this supported a view that compliance with treatment would reduce the risk of future violent offending.


Orders Made

  • The offender was sentenced to imprisonment with a non-parole period of two years and a head sentence of four years, commencing 10 March 2009.
  • The non-parole period was set to expire on 9 March 2011, on which date the offender became eligible for release to parole.

Key Takeaways

  • Where an offender's mental illness is the prime causative factor in serious offending, a sentencing court may reduce the weight accorded to general deterrence, though personal deterrence is not rendered irrelevant.
  • Special circumstances justifying an extended parole period can be established where the offender requires prolonged supervision to ensure compliance with mental health treatment and to address drug use that contributes to the risk of relapse and reoffending.
  • A standard non-parole period does not apply directly where a guilty plea has been entered, but it continues to serve as a sentencing guidepost under the relevant statutory framework.
  • Objective seriousness above the midpoint was established here by the combination of factors including the victim's vulnerability while sleeping, the domestic setting, the use of an armed weapon, and the severity of the injuries inflicted.
  • The District Court's sentencing approach reflected that the criminal justice system has an interest in structuring sentences to encourage mentally ill offenders to engage with prescribed treatment, as a means of protecting the community from future violent offending.
