The appeal
36 The Crown prosecutor in this Court, who did not appear before Sperling J, submitted that the overall sentence of twenty-six years imprisonment is manifestly inadequate. While he argued that a life sentence would have been appropriate, he recognised the element of double jeopardy in Crown appeals and did not urge us to take that course if the appeal were allowed. He also argued that, in structuring the sentences, his Honour failed to determine the sentence appropriate for each of the three offences and then to consider questions of concurrence, accumulation and totality, in accordance with the principles enunciated in Pearce v The Queen (1998) 194 CLR 610 at 623-4. The proper application of those principles, it was said, would have led to a partial accumulation of the sentences so as to produce a significantly longer overall sentence.
37 Finally, as I have said, the Crown prosecutor challenged a number of his Honour's findings of fact. It is convenient to deal with that aspect of the appeal first. I do so bearing in mind the familiar principles governing appellate review of the findings of fact of a primary judge. Those principles were restated, with reference to authority, by Greg James J in Reg v Khouzame [2000] NSWCCA 505 at pars 33-47.
38 The Crown's position in the sentence proceedings had been that Mrs Park was killed first and that the children were then killed because they had witnessed their mother's death. It was argued that, whatever might have been the respondent's emotional state when he killed his wife, he killed the children "in a calculated and cool headed state of mind." His Honour accepted that Mrs Park was probably killed first, but he thought it "reasonably possible that the children were then killed out of some misguided notion, arising in the emotional aftermath of her death, that it would be inhumane for the children to be left alive without their mother." His Honour went on to say that he was not satisfied beyond reasonable doubt that the respondent killed the children otherwise than "in a state of emotional turmoil."
39 The Crown prosecutor before us submitted that his Honour's observation that the killing of the children could have been motivated by a desire to spare them life without their mother was "totally speculative and unsupported by any evidence." However, I do not understand his Honour to have made any positive finding to that effect. Read in context, it is clear that his Honour was saying no more than that the evidence admitted of possible scenarios other than that for which the Crown contended. What mattered for the purpose of sentence was that his Honour was not satisfied that the children were killed in cold blood.
40 Allied to this is his Honour's finding that he was not satisfied that the respondent killed his wife and children in order to avoid his potential liability for child support. The Crown prosecutor before us argued that that was the true motive, describing it as "an almost overwhelming inference" from the evidence. No doubt, as his Honour did find, the respondent's anger engendered by the communication from the Child Support Agency played a role in the killings. Indeed, that he killed his family to avoid any liability to support the children is a reasonable hypothesis. However, it cannot be said that the evidence compelled such a conclusion beyond reasonable doubt, any more than that could be said of a conclusion that the children were killed in cold blood.
41 As to the manner in which the killings were carried out, his Honour noted the forensic pathologist's opinion that the deceased had been suffocated and continued:
… I could not be satisfied beyond reasonable doubt that each of the deceased was not rendered unconscious in some other way before bags were placed over the head. Accordingly, I make no finding that the offences are aggravated by the deceased having died uncomfortable deaths or having been in fear before death.
42 The Crown prosecutor in this Court challenged that view of the facts, relying on the evidence not only that there were bags over the head of the three deceased but also that they were bound with rope. Again, an inference that the deceased were killed in more distressing circumstances is available but such a finding beyond a reasonable doubt was not inevitable. Generally, as his Honour observed, the paucity of evidence of what occurred at the Eastwood flat on that fateful night militated against positive findings adverse to the respondent.
43 There were other matters established by the evidence to which, the Crown prosecutor submitted, his Honour failed to attribute due significance as aggravating features. These were the disposal of the bodies of the deceased, the false story that they had moved to Brisbane, and the sale of the furniture from the flat at Eastwood and plundering of their bank accounts.
44 As to the disposal of the bodies, his Honour contrasted the present case with Reg v Leonard (CCA, unreported, 7.12.98), in which the offender had dismembered the body of one of his victims and kept the body parts in a refrigerator for some months before dumping them in a creek. The sentencing judge in that case had seen this behaviour as evidence of the offender's contempt for the victim and his lack of remorse for his crime. In the present case, his Honour noted that the bodies were not mutilated or interfered with and were disposed of shortly after the killings. His Honour saw their disposal, together with the false story about the deceased's whereabouts, as being motivated by the respondent's desire to avoid detection. While observing that the respondent could be "criticised for this course of conduct", his Honour did not see it as amounting to "a significant consideration in aggravation of the offences." That is a conclusion which was fairly open.
45 His Honour saw the sale of the furniture and the withdrawal of the money from the bank accounts as a continuation of the respondent's established pattern of behaviour as an habitual gambler. I earlier referred to the evidence that the proceeds of the sale of the furniture were lost by gambling. About this aspect of the evidence his Honour said:
This history demonstrates a callous attitude on the part of the prisoner towards his family. It does not seem to me, however, to add anything of significance by way of aggravation to the objective seriousness of the crimes. They speak for themselves.
