29It will be apparent from the portions that I have related from the sentencing judge's remarks that there are a number of errors. The sentencing judge concluded that each offence was of similar seriousness and gave no indication of the impact of the matters on the Form 1 on the sentence for the relevant offences.
30The respondent accepted that his Honour had not dealt with those matters but submitted that the argument was technical and was "precisely the sort of reasoning which the introduction of s 53A of the Crimes (Sentencing Procedure) Act 1999 was intended to overcome, that is, overly technical grounds of appeal which even if established would not affect the overall sentence."
31Section 53A was introduced to ameliorate the difficulties that had emerged with the obligations required of a sentencing judge by reason of the High Court's decision in Pearce v R [1998] HCA 57; (1998) 194 CLR 610. The section is in the following terms:
"(1)A court may, in sentencing an offender for more than one offence, impose an aggregate sentence of imprisonment with respect to all or any 2 or more of those offences instead of imposing a separate sentence of imprisonment for each.
(2)A court that imposes an aggregate sentence of imprisonment under this section on an offender must indicate to the offender, and make a record of, the following:
(a)the fact that an aggregate sentence is being imposed,
(b)the sentence that would have been imposed for each offence (after taking into account such matters as are relevant under Part 3 of any other provision of this Act) had separate sentences been imposed instead of an aggregate sentence.
(3)Subsection (2) does not limit any requirement that a court has, apart from that subsection, to record the reasons for its decisions.
(4)The term, and any non-parole period, set under this Division in relation to an aggregate sentence of imprisonment is not revoked or varied by a later sentence of imprisonment that the same or some other court subsequently imposes in relation to another offence.
(5)An aggregate sentence of imprisonment is not invalidated by a failure to comply with this section."
32Section 53A(1) allows a court to impose an aggregate sentence instead of a separate sentence of imprisonment for each count. However, s 53A(2) requires the sentencing judge to indicate to the offender the sentence that would have been imposed for each offence had separate sentences been imposed instead of an aggregate sentence. A sentencing judge is accordingly required to give consideration to the criminality involved in each offence and, where appropriate, have regard to any matters on a Form 1 when defining the sentence that would have been imposed for an individual offence. Subsection 5 will save from invalidity any aggregate sentence that has been imposed in circumstances where the sentencing judge has failed to comply with s 53A(2)(b) or any other requirement of the section.
33It follows that in the present case, although his Honour should have considered and recorded the sentence to be imposed for each individual offence, the failure to do so does not invalidate the sentence.
34The Crown submitted that the sentencing judge was also in error when he said that the respondent was "a drug addict engaging in unplanned break and enters" and that his Honour should rather have found that the offences were planned. The foundation for this submission was the fact that the respondent was wearing gloves during the commission of the offences and had chosen property at Randwick because it had no security cameras. It was further submitted that the agreed facts disclosed that it was common ground that the offences were planned and that his Honour should have indicated to the parties that he had proposed to depart from this agreed fact.
35Counsel for the respondent submitted that the fact that the respondent carried gloves and examined premises before he broke into them is not inconsistent with the finding that the offences were unplanned. To my mind, this submission should be accepted. Although it is clear that the respondent had set about robbing premises to obtain goods that he could turn into cash, the extent of his planning was confined to an intention to carry out a robbery on premises that he found to be suitable. He had not otherwise set about planning the robbery of any particular premises, nor had he organised himself accordingly. To my mind, his Honour was not wrong to describe the offences as he did.
36At the heart of the sentencing of the respondent is his mental illness. There is no doubt that he is suffering from schizophrenia. The Crown submitted that the extent to which the respondent's schizophrenia mitigated the offences was limited because there was evidence before his Honour that the illness was triggered by the respondent's consumption of drugs and alcohol.
37It is clear from the reports tendered at the sentence hearing that the respondent has psychotic episodes when he ceases to take his mediation or resorts to the consumption of alcohol or prohibited drugs. However, in my opinion, the evidence does not determinatively show that the respondent's substance abuse "triggered" his illness. The respondent was diagnosed with schizophrenia in 2004. Although the respondent indicated to both Mr Rowe and Dr Nielssen that he believed that his illness was triggered by his use of methylamphetamine, the respondent gave a history of drug use in which he claimed to have first used that drug in 2007, three years after his diagnosis. Neither Mr Rowe, nor Dr Nielssen express an opinion about what may have "triggered" the respondent's schizophrenia.
38The principles relevant to the sentencing of a person who is suffering from mental illness or intellectual handicap have been considered in many cases. I endeavoured to summarise them in Director of Public Prosecutions (Cth) v De La Rosa [2010] NSWCCA 194, (2010) 79 NSWLR 1 at [177] - [178], where I said:
"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 see, eg, R v Engert (1995) 84 A Cnm R 67, R v Tsianas [1996] 1 VR 398 at 400, R v Fahda [1999] NSWCCA 267 at [40] - [48], Launtsen v R [2000] WASCA 203, (2000) 114 A Cnm R 333 at [43] - [51], R v Harb [2001] NSWCCA 249 at [35] - [45], R v Israil [2002] NSWCCA 255, R v Hemsley [2004] NSWCCA 228 at [33] - [36], R v Verdins [2007] VSCA 102 at [32] Courtney vR [2007] NSWCCA 195 at [14]-[18], and R v Henry [2007] NSWCCA 90 at [28] 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 R v Henry [1999] NSWCCA 111, 46 NSWLR 346 at [254], Miller v R [1999] WASCA 66 at [23], RvJiminez [1999] WASCA 7 at [23], [25], Tsiaras at 400, Launtsen at [51], Israil at [23], R v Pearson [2004] NSWCCA 129 at [43], Henry [2007] NSWCCA 90 at [28].
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 Engert at 71, R v Wright (1997) 93 A Cnm R 48 at 50 - 51, Israil at [22], Pearson at [42], Henry at [28].
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 Tsians at 400, Jimmez at [25], Israil at [26], Henry at [28].
It may reduce or eliminate the significance of specific deterrence Courtney at [14], Tsiaras at 400, Israil at [25], JW at [192].
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 Israil at [24], Henry at [28] 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 R v Lawrence (2005) NSWCCA 91 per Spigelman CJ at [23] - [24].
I should stress that the mental health problems of an offender need not amount to a serious psychiatric illness before they will be relevant to the sentencing process. The circumstances may indicate that when an offender has a mental disorder of modest severity it may nevertheless be appropriate to moderate the need for general or specific deterrence: R v Skura [2004] VSCA 53; R v Verdins [2007] VSCA 102; (2007) 16 VR 269 at [5]."
39For the reason that the respondent suffered from serious and long standing mental illness, in particular chronic schizophrenia, it was open to his Honour to fashion the sentence by giving general and specific deterrence less weight than in the usual case. It was also appropriate for his Honour to emphasis the need for rehabilitation. Accordingly, in so far as Ground 4 asserts his Honour's approach to this issue was in error, it must be rejected.
40The question that arises is whether, in the result, the non-parole period that his Honour imposed was manifestly inadequate, requiring the intervention of this Court (Ground 5).
41The Crown does not submit that the total term of the respondent's sentence was manifestly inadequate. The argument was directed to the non-parole period. It was submitted that his Honour, in his brief remarks on sentence, did not make plain whether he had had regard to all of the matters relevant to the offences, correctly identified the criminality involved and had regard to any matters of aggravation when identifying the non-parole period which he imposed. It was submitted that by imposing a non-parole period of 18 months with a head sentence of 7 years, a ratio of 21.42% (compared with the statutory ratio of 75%), his Honour had given excessive weight to the respondent's mental illness and his need for rehabilitation.
42The Crown emphasised that for the offence committed in 2007 the respondent was sentenced to a head sentence of 4 years. Shortly after the sentence had expired the respondent had offended again. The Crown submitted that, by his conduct, the respondent had disavowed any intention to rehabilitate himself and that, accordingly, the need for rehabilitation did not justify a finding of special circumstances.
43It was submitted that in light of the number of offences, the matters on the Form 1, the respondent's criminal history, the maximum penalty for the offences and the weight properly given to the respondent's mental illness the non-parole period should have been greater.
44The sentencing of the respondent was difficult. But for his history of significant mental illness, his record and the seriousness of the offences which he committed would have required a sentence with a non-parole period significantly greater than was imposed by his Honour. Offences which are committed by intruding into a person's home with the intention of taking their property are serious and demand significant punishment. This is recognised by the fact that the legislature has imposed a maximum penalty of 14 years imprisonment for the various offences that the respondent committed.
45The difficulty in relation to the respondent is that after he was sentenced for the offences in 2007 and later released to parole he was able to re-establish himself in the community without offending. Notwithstanding his mental illness, he did not offend again until after his parole period had expired and he regressed into consuming prohibited drugs. This suggests that if he is able to obtain effective treatment and responds appropriately to it, there is a real chance that he can be rehabilitated and become a law abiding member of the community. He is a man of 32 years of age and, as described by his Honour, has a physical capacity which would enable him to obtain employment suitable to his level of intellectual and emotional functioning. By imposing a relatively short non-parole period, but a lengthy period on parole, his Honour ensured that the respondent would receive the benefit of supervision while on parole together with the prospect that, if he offended during that time, he would be returned to prison. It seems that that possibility had operated as an effective disincentive for him to offend after he was sentenced in 2007. It is reasonable to assume that this will again be the case in relation to the sentence which his Honour imposed.
46His Honour recognised the need for the respondent to receive effective and appropriate psychiatric treatment. So much is obvious. His Honour concluded that this treatment could best be provided in the community, the facilities within the prison system being less suitable. I am not persuaded that this finding was inappropriate. It influenced his Honour's decision to provide a relatively short non-parole period. There was no error in his Honour reaching this conclusion.
47Notwithstanding the seriousness of the offences that the respondent committed I am satisfied that the approach that his Honour took was, in all the circumstances, available. Although a longer period of fulltime custody would not have been inappropriate, I am not persuaded that the sentence imposed was manifestly inadequate requiring the intervention of this Court.
48Although the respondent filed an application for leave to appeal no submission was made to support it. It was filed only to protect the respondent in relation to the head sentence if the Crown appeal was upheld.
