The character, antecedents, age, means and physical or mental condition of the offender [163]
- The offender was born in Australia on 12 December 1993. His parents had migrated to Australia from Bangladesh that year. [164] He was 22 years of age at the time of the attack on Mr Greenhalgh and is now 25. In about 2001, the offender's parents purchased a home in Minto. His father left the family in 2008 and the offender and his only sibling, a sister who is six years his senior, were cared for by their mother. [165] The offender's sister moved out of the Minto premises with her husband in January 2014. From that time until her death from cancer, the offender's mother was his principal carer. The offender appears to have some ongoing relationship with his sister and brother-in-law.
- Between 2006 and 2011 the offender attended Hurlstone Agricultural High School, a selective secondary school. [166] In his Higher School Certificate in 2011 he achieved an Australian Tertiary Admission Rank of approximately 96. In 2012 he commenced studying a Bachelor of Pharmacy Degree at the University of Sydney. [167] The level of his academic performance is reflected in the fact that he was awarded a number of credits and high distinctions. [168] The offender is, to say the least, a highly intelligent man.
- In the course of submissions, counsel for the offender made reference to the principles applicable to the sentencing of youthful offenders. [169] In my view, those principles have no application in the present case. The offender was not a youth at the time of his attack on Mr Greenhalgh. On the contrary, he was a mature and intelligent 22 year old. Even it were the case that youth was a relevant factor, its weight would be diminished given the nature of the offending. [170]
- The offender appeared before the Campbelltown Local Court in 2013 in respect of charges of larceny and destroying or damaging property, such property being Australian flags which were on display at a residence in his local area. The charges were dealt with pursuant to s 32 of the Mental Health (Forensic Provisions) Act 1990 (NSW). Whilst the offender is to be regarded as a person of prior good character, that factor is of reduced significance in a case such as the present. [171]
- The offender's history of mental illness includes his admission to Campbelltown Hospital in April 2013 with a provisional diagnosis of OCD, and a differential diagnosis of prodromal psychotic illness. [172] At the time of his discharge, some 10 weeks later, the confirmed diagnosis was one of OCD.
- As I have noted, differing opinions were expressed by the experts called in the trial as to the offender's mental state at the time of his offending. Dr Adams and Dr Reznik concluded that the offender was suffering from schizophrenia. Professor Greenberg's opinion was that the offender was suffering from OCD. In her affidavit tendered by the Crown, Dr Spencer expressed the opinion that the offender currently suffers from schizophrenia for which he is being medicated in custody. [173]
- It was the Crown's position that it was not necessary for me to reach an affirmative conclusion as to the nature of the offender's present mental illness and I did not understand counsel for the offender to cavil with that proposition. On any view of it, the offender suffers from some form of mental illness, be it schizophrenia or OCD. The question is how that impacts upon sentence generally, and the question of general deterrence in particular.
- The Crown submitted that in circumstances where there was no causal connection between the offender's mental illness and his offending, any moderation of general deterrence should not be great. The Crown further submitted that the evidence established that the offender's conditions of custody were not rendered any more onerous on account of his mental illness. In this regard, the Crown pointed to the affidavit of Dr Spencer [174] which, it was submitted, established that the offender was being treated satisfactorily. The Crown submitted that in all of these circumstances, general deterrence remained an important consideration.
- Whilst accepting that there was no causal connection between the offender's mental illness and his offending, counsel for the offender submitted that mental illness remained a relevant consideration on sentence in terms of general deterrence. Counsel took particular issue with the proposition advanced by the Crown that the offender's conditions of custody were not rendered more onerous as a consequence of his illness. He submitted that the fact that the offender had a mental illness which required treatment at all necessarily rendered his conditions of custody more onerous than might otherwise be the case.
- On any view of the evidence, the offender suffers from some form of mental illness. In Director of Public Prosecutions v De La Rosa [175] McClellan CJ at CL set out the following principles regarding the relevance of mental illness on sentence: [176]
177 Where an offender is suffering from a mental illness, intellectual handicap or other mental problems the courts have developed principles to be applied when sentencing. … They can be summarised in the following manner:
● Where the state of a person's mental health contributes to the commission of the offence in a material way, the offender's moral culpability may be reduced. Consequently the need to denounce the crime may be reduced with a reduction in the sentence.
● It may also have the consequence that an offender is an inappropriate vehicle for general deterrence resulting in a reduction in the sentence which would otherwise have been imposed.
● It may mean that a custodial sentence may weigh more heavily on the person. Because the sentence will be more onerous for that person the length of the prison term or the conditions under which it is served may be reduced.
● It may reduce or eliminate the significance of specific deterrence.
● Conversely, it may be that because of a person's mental illness, they present more of a danger to the community. In those circumstances, considerations of specific deterrence may result in an increased sentence. Where a person has been diagnosed with an Antisocial Personality Disorder there may be a particular need to give consideration to the protection of the public.
- The offender's mental illness was not, in any way, causally connected to his offending. That said, I am unable to accept the submission of the Crown that the fact that the offender's current mental health is being satisfactorily treated in custody leads to a conclusion that his custodial conditions are not rendered more onerous than might otherwise be the case. The fact that the offender has a mental illness at all must have some effect upon his conditions of custody and I have taken that into account. However, given the nature of the offending in the present case, general deterrence remains relevant and is not significantly moderated by mental health considerations.
