I see general deterrence to be of less importance in this case than it might be in another case because, as he was suffering from depression at the time when he committed the offence, the offender is not an appropriate medium for making an example to others.
31 It was not suggested that either of the third or fourth principles identified in Hemsley (supra) was relevant to the present case. However it was submitted that his Honour had erred in not giving effect to the first of the principles identified in Hemsley (supra). In that context reference was made to the following passage in the sentencing judge's remarks:
However, I do not have any doubt that, when he started his car's engine, he intended to commit suicide and to take his son with him and that, notwithstanding that he was suffering from depression, he knew what he was doing and what would be the consequences of what he was doing . (emphasis added)
32 It was thus contended that it was clear that his Honour had not concluded, as he should have, that the applicant's moral culpability was moderated because of his mental illness.
33 However, there was also other evidence upon this issue which the sentencing judge was bound to consider. First, there was the entire course of conduct upon which the applicant had embarked on the day of the incident which included the lengthy drive which he had undertaken with his son to the forest. It was a course of conduct which had lasted for many hours and involved a number of quite deliberate acts on the part of the applicant. Moreover, in the discharge summary following the applicant's release from Bloomfield Hospital, it was observed that:
No psychotic thinking, no hallucinations or delusions. No evidence of cognitive deficit and oriented for memory. Judgement and insight present i.e. feels rejected by wife. Says feels alone and dejected, feels guilty and upset. He assured that he will not do this again as it will destroy him more. Diagnosis was Adjustment Disorder with depressed mood and deliberate self harm behaviour and differential diagnoses was depression first onset, situation specific. The treatment plan was a short stay in hospital and to commence anti depressants.
34 It is also convenient, in considering the applicant's state of mind on the day of the offence to refer to some other parts of the affidavit to which I earlier referred:
In or about the start of November 2005 I received a very personal email from [my wife] in relation to the breakdown of our relationship. I recall receiving the email on the Friday afternoon, after I got home from work. Reading the email was extremely difficult for me. I understood that our relationship was over, and it seemed to me that this letter was just unnecessary.
The email also showed that it had been forwarded to my elder sister G. and her husband. There was also a version in Spanish, which I assumed was intended for my parents to read as they are Spanish. Reading the email, I felt it was defamatory and extremely one-sided. It alleged abuse by me against [my wife].
When [my wife] left, I found so did most of my fiends. All that I had left was my immediate family and I was distraught in the knowledge that they had received a copy of this email correspondence, I felt it would have a big impact on our relationship and what they thought of me.
After having read the letter, and in the knowledge that my whole family had also received it, I lapsed into a state of complete depression. I admit to having feelings at that time like I wanted to end my life because I felt like my family were my last support, and now they wouldn't want to have anything to do with me either. I felt totally isolated.
I felt more positive on the Saturday. In accordance with the arrangement I had with [my wife] [she] dropped A around to me the next day, which was the Sunday. A. was tired, and so I put him down for a sleep. While he was asleep I cooked a meal for him, and when he woke up, he ate a big meal.
That Sunday was also my sister C's birthday, so after A. woke up and after he had had something to eat, we went and purchased a present for C. and I had decided that we would then take it to her. We went home briefly and A. had a bottle of milk, and we then drove to my parent's home where my mother had said previously that my sister would be that day. I was surprised however to see that my older sister's car was also parked in the driveway.
For some reason, this affected me greatly, and I developed an impression - which I now realise was all wrong - that my family had gotten together without me to discuss the letter [my wife] had sent them and my failed relationship. It just seemed to me that it was strange my mother hadn't called me to let me know of any get together.
I went inside with A. and stayed for a while, but had strong feelings that I was all alone the whole time. I felt that my father was not making eye contact with me. I had feelings that I had lost my family. I had already lost my circle of friends, and now I was going to lose my family.
I had an intense resurgence of the feelings I had had on the Friday to end my life, but now they seemed a lot stronger. I truly thought I had no one.
I now realise that I was really not thinking clearly at all. My feelings of depression and sadness about my relationship were affecting my judgment and making me irrational. As it turned out, my parents had not even read the letter received from [my wife], but I didn't know this at the time.
35 In any event, as senior counsel for the applicant candidly recognised, Dr Nielssen's opinion had to be evaluated in the light of the fact that the applicant had pleaded guilty to the offence, which meant that the applicant himself recognised that he had committed the prohibited act "maliciously".
36 In R v Engert (1995) 84 A Crim R 67, Gleeson CJ, with the concurrence of the other members of the court, said:
Persons suffering from mental disorders frequently come into collision with the criminal justice system. Sentencing such persons commonly confronts judicial officers with the need to make a sensitive discretionary decision. Sentencing is essentially a discretionary exercise requiring consideration of the extremely variable facts and circumstances of individual cases and the application of those facts and circumstances to the principles laid down by statute or established by the common law. The principles to be applied in sentencing are in turn developed by reference to the purposes of criminal punishment.
…
A moment's consideration will show that the interplay of the considerations relevant to sentencing may be complex and on occasion even intricate. In a given case, facts which point in one direction in relation to one of the considerations to be taken into account may point in a different direction in relation to some other consideration. For example, in the case of a particular offender, an aspect of the case which might mean that deterrence of others is of lesser importance, might, at the same time, mean that the protection of society is of greater importance. That was the particular problem being examined by the court in the case of Veen (No 2). Again, in a particular case, a feature which lessens what might otherwise be the importance of general deterrence, might, at the same time increase the importance of deterrence of the offender.
