Basis of liability for murder - relevant intent
24It is uncontroversial that the offender's plea of guilty to murder carries with it an acknowledgment that she caused the death of the deceased. In the present case, the offender's version of the events surrounding the death of the deceased is neither accepted by the Crown nor on one view consistent with the expert medical evidence. The precise cause of death is therefore not known and cannot be ascertained. That necessarily confounds any proper analysis aimed at determining beyond reasonable doubt the question of whether or not the offender committed an act or acts with the intention of killing the deceased, or did so only with an intention to cause grievous bodily harm, or was recklessly indifferent to the life of the deceased.
25The question as to whether there is a "sliding scale of seriousness" according to whether a murder offence was committed with an intent to kill or cause grievous bodily harm, or with reckless indifference appears to be unsettled. In Apps v R [2006] NSWCCA 290, Simpson J said [at 49]:
"[49] Certainly, in a case of murder, the state of mind in which the offence is committed is a relevant consideration going to objective seriousness. As is well known, murder may be established by proof of an act causing death committed when the act is accompanied by any one of three states of mind: in descending levels of seriousness they are: intention to kill, an intention to cause grievous bodily harm, or reckless indifference. I have no doubt that an intention to kill as distinct from either of the two alternatives, is a consideration tending to greater objective seriousness rather than the lesser. So much is obvious..."
26However, in Tran, Hoai Vinh v R [2011] NSWCCA 116, after an analysis of a number of authorities on the issue (including Apps), Hidden J said at [39].
"[39] What emerges from these cases is what one would expect. Whether a killing was premeditated or, in any event, whether it was accompanied by an intention to kill are important questions in an assessment of where a murder lies in the range of objective gravity, but of themselves are not necessarily determinative. Invariably, there will be other circumstances in the particular case bearing on that assessment. In Versluys [2008] NSWCCA 76 at [36], McClellan CJ at CL said:
'When assessing the objective seriousness of any offence the court is required to identify the relevant facts and form an intuitive judgment based upon the experience of the courts in sentencing for the particular offence. This is true of murder as it is of any other offence... .'
Of course, the assessment of the objective gravity of an offence is an important aspect of any sentencing exercise, and one which requires careful consideration. For obvious reasons, this is particularly so when sentencing for offences for which a standard non-parole period is prescribed."
27Johnson J agreed with Hidden J but added a further observation at [44]-[45]:
"[44] Although it will generally be the case that an intention to cause grievous bodily harm is less culpable to a greater or lesser degree than an intention to kill in a case of murder, that is not always so and there may be circumstances where an intention to inflict grievous bodily harm could reflect similar criminality to other cases involving an intention to kill: R v Nelson (NSWCCA 25 June 1996, unreported); R v Hillsley [2006] NSWCCA 312; 164 A Cnm R 252 at 258 [16].
[45] These statements have been made in decisions of the Court of Criminal Appeal which predate the standard non-parole systems (R v Nelson) and which postdate that system (R v Hillsley). The statements are pertinent to the determination of objective seriousness of a crime of murder under the standard non-parole period system and, in my view, should be kept in mind in conjunction with the authorities and principles referred to in the judgment of Hidden J."
28Since first frankly revealing her involvement in this matter, the offender has consistently maintained that her act causing the deceased's injury was "an accident". Indeed, the only account of the act causing death is that given by her. It was contended by the Crown that the offender's acts committed towards the deceased were more extreme than she admitted. It is agreed that the deceased sustained a lethal injury at the hands of the offender. The Crown submitted that the evidence concerning the number and direction of impacts apparently sustained by the deceased is at odds with "a little nudge" and a fall. It also submitted that I was entitled to find that the impacts described by Dr Middleton were occasioned during an assault upon the deceased by the offender, which resulted in a life-threatening state of health.
29The Crown contended that the number and intensity of the impacts inflicted upon a small and defenceless six-year-old child provided powerful evidence of an intent to cause really serious injury. Coupled with other evidence, that was sufficient to establish an intention to kill. The Crown raised the following matters in that context:
The offender's attitude towards the deceased
30On 3 July 2010, the offender bit the deceased. The deceased was aged 15 months at the time. On 1 May 2006, the offender pleaded guilty to assault occasioning actual bodily harm and was subsequently released on a s 9 bond for a period of 12 months.
31The deceased's physical resemblance to the offender's former partner apparently annoyed her and triggered physical and verbal abuse towards the deceased. A few weeks prior to the deceased's death, the offender wanted her father to take the deceased because she predicted that she would kill her. According to the Crown, this statement informs how the offender felt towards the deceased and more importantly what she would do to her.
32The offender has been recorded saying that after the deceased went "funny", she put her into the shower, and then into bed. She did not call an ambulance or make any effort to obtain medical assistance, thereby demonstrating a high level of disregard for the deceased. The Crown contends that the offender's treatment of the deceased's body after death is further evidence of enmity towards her.
The offender's intention to relocate the deceased
33The offender was at one time intending to send the deceased to live with her father in Canberra. The Crown contends that this suggests that there was an insurmountable problem between the offender and the deceased, and that the offender's ability to cope with the deceased had reached an irreversible level. The offender's proposal was effectively to send her six-year-old daughter to live interstate with a man who she had barely seen or spoken to for 15 years and who the offender claims had abused her as a child.
The offender's concealment of the deceased
34The deceased only attended school for four days, and had little contact with people other than the offender. She was kept in the apartment because she was regularly exhibiting signs of injury or abuse, and the offender could not risk those injuries being observed by others, particularly given the offender's previous dealings with DoCS and her opinion of its "interference". The offender was unconcerned about the deceased's attendance and development at school, pre-school, or day care, and did not attempt to include her in normal day-to-day activities such as playing in the park or visiting the shops.
Injuries sustained by the deceased prior to death
35There is considerable evidence that the deceased sustained many severe injuries during her life apart from those that ultimately caused her death. Such evidence is only relevant if I were satisfied beyond reasonable doubt that the offender caused them. The Crown contended that it would be relevant in a number of ways, primarily in order to support the proposition of the offender's enmity towards the deceased.
36Dr Orde's evidence identified ten separate sites of injury to the surface of bones that occurred in the weeks and months prior to the deceased's death. These injuries included sharp-edged teeth fractures, injuries to the maxilla, a severe blunt force injury to the lower left side of jaw bone, a severe blunt force late healing injury to the right parietal bone above the right ear, healing fractures of the lower margins of the nasal bones caused by significant force, late healing injuries to both clavicles and a healing fracture of the upper right humerus occasioned by traction or twisting two to four weeks prior to death. None of these injuries would appear to have been the subject of medical intervention.
37The Crown contended that the history of injuries to the deceased demonstrated an escalation in their seriousness, particularly in the last 18 months of her life and that at least some of them, such as the bony injuries, amounted to grievous bodily harm. The Crown contended that even if I were not satisfied that the offender caused them, I could still be satisfied that she was the primary caregiver at the time the deceased sustained the injuries but that she did not obtain medical assistance for her. These matters are said to be relevant to the offender's state of mind at the time of the act causing death.
38The evidence indicates that both the offender and Mr Smith had the care of the deceased at all relevant times. Even if Robert Smith had caused the injuries, it would have been apparent to the offender. Unless I can be satisfied that the offender was directly responsible for these injuries, the evidence cannot be used against her except in terms of her failure to summon medical care.
39The offender emphasised the following matters. Dr Orde could not determine the cause of death. The only evidence of injury that is capable of revealing a cause of death is Dr Middleton's evidence of "more than one blow" to the deceased's head.
40It is apparent that the offender did not call for medical help when she saw the severity of the deceased's injury, despite the deceased not dying for some hours. It is on this basis that the offender says she acted with reckless indifference to the deceased's life.
41It is acknowledged in the agreed facts that the offender had difficulty coping with parenting, and that she was at times bad-tempered towards the deceased. Her father's evidence that the offender said she would hurt or kill the deceased is derived from his conversation with her that took place more than a month before the deceased died and in the context that he telephoned the offender possibly an hour or two after their first conversation, by which time the offender had "calmed down".
42The offender contended that her participation in the disposal of the deceased's body and her lies to the police and the media were not evidence of "enmity" towards the deceased, but rather evidence of her continuing desire to avoid detection and the likely removal of her children.
43The offender submitted that there was no evidence to establish anything other than that she had a reckless indifference to the deceased's life.
44I do not consider that it is possible to find beyond reasonable doubt that the offender inflicted the earlier identified non-lethal injuries upon the deceased. The collocation of events and circumstances identified by the Crown undoubtedly raises a high level of suspicion that the offender was either directly involved or indirectly complicit in the infliction of the injuries. Suspicion alone is not however a proper basis to make findings adverse to the offender.
45On the contrary, I do find beyond reasonable doubt that the offender at least recklessly failed to take any appropriate steps to deliver or secure prompt or appropriate care and attention to the deceased after she sustained her ultimately fatal injuries. Such a finding is available beyond reasonable doubt upon the basis that the offender committed the act that eventually caused death, that she was aware that the deceased had sustained a life threatening condition, that she realised that death would probably occur if medical attention was not sought but that she proceeded to take that risk nothwithstanding.
46I pause to observe that there is no expert or other medical evidence or opinion offered to enable me to determine the time of death of the deceased. It is not therefore possible for me to make any findings beyond reasonable doubt about the nature or extent of the offender's opportunity, in the period between her infliction of the injuries that caused the death and when it occurred, to obtain medical assistance for the deceased or correspondingly about whether that would have altered the outcome. For example, according to a version of what occurred given by the offender, the deceased went like jelly and was defecating during the unsuccessful attempts to revive her. One might be prepared to conclude from those matters that the deceased had already died before, or at least by the time, she was taken to the shower. It will be apparent, however, that such a conclusion cannot be reached without evidence and certainly not beyond reasonable doubt. The only findings available upon the time of death are that the deceased died at some time before the offender observed her the following morning and that no medical assistance was sought before that occurred.
47Logically anterior to a finding that the offender acted with reckless indifference to human life, and necessarily in this case more difficult, is the question of whether or not the offender also either intended to kill the deceased or committed the act or acts that killed her with the intention of inflicting serious injury. Written submissions provided to me by Ms Manuell SC for the offender specifically concede that the deceased "sustained a severe head injury at the hands of the offender and that [she] died as a result". The offender's concession, however, is relevantly neutral in this context.
48On the one hand the offender's version of events, that she gave the deceased "a little nudge" with her foot and that she struck her head on the bottom of the bed, cannot be accommodated by or within the expert evidence that the deceased sustained a series of blows of sufficient force to cause her teeth to become chipped or fractured. I reject the suggestion that those injuries could have been caused by striking her head on the bed as suggested by the offender. I am satisfied beyond reasonable doubt that they were not. On the other hand, the expert opinions concerning the posited force and direction of the blows or impacts that caused the deceased's observable injuries do not circumscribe or explain precisely what happened to her in fact. There is therefore an evidentiary gap between the offender's concession that she committed the act that killed the deceased and a satisfactory understanding of just how that occurred. Any finding beyond reasonable doubt that the offender committed the act that killed the deceased with the intention of doing so or of causing her really serious injury must therefore accommodate that gap.
49It was in these circumstances that Ms Manuell's submissions quite understandably directed attention to the extent of the use that could be made of Dr Middleton's prognostications concerning what happened to the deceased and specifically to the issue of how many blows might have been inflicted upon her. It is necessary to consider them.
50Dr Middleton gave evidence of his opinion as to the number of blows said to have been sustained by the deceased. He was first qualified in respect of this matter in April 2011. Since then he has provided four reports and had a conference with the DPP on 22 June 2012. Dr Middleton agreed that in each of his reports he gave the opinion that the deceased sustained "more than one blow". In the notes of the conference on 22 June 2011, Dr Middleton is noted as saying, "If limited to one side, there would not have been bilateral injuries to the teeth, so a number of collisions to the jaw occurred". The words "a number of collisions" are not, on their face, inconsistent with Dr Middleton's earlier, repeated opinion that there was "more than one blow".
51In his oral evidence, Dr Middleton said, "The absolute minimum would have to be three [blows] and I would be hesitant to go that low. I would say more like four or five absolute minimum." In cross-examination he was asked, "In fact, in your reports, when you were carefully considering the material over a period of more than two years, the only conclusion you could safely draw was that there had been more than one blow; isn't that right?" He replied, "That's correct."
52Dr Middleton's evidence that there were possibly three but more likely a minimum of four or five blows sustained by the deceased is clearly more adverse to the offender than simply "more than one blow." He agreed that he had not previously described the blows in that way. It must be presumed that the Crown did not know Dr Middleton was going to give this evidence, since notice of it was not given to the offender. It was submitted in these circumstances that Dr Middleton's evidence of three, four, five or more blows had the hallmarks of recent invention and should not be accepted.
53Additionally, a fundamental difficulty with Dr Middleton's evidence as to the number of blows sustained by the deceased is that it is evidence of biomechanics. Dr Middleton is not a biomechanic and had no expertise in the area, both matters with which he agreed. He also agreed that there were no papers or research that he could rely upon to support a more exact estimate of the number of blows. Dr Middleton's attempt to quantify the number of blows the deceased sustained is clearly a matter that is outside his expertise. The purported, and spurious, proffering of "expert" evidence in the field of biomechanics was discussed in Wood v R [2012] NSWCCA 21 at [466] - [477].
54Moreover, in Makita (Australia) Pty Ltd v Sprowles [2001] NSWCA 305; (2001) 52 NSWLR 705 at [85], Heydon JA said:
"In short, if evidence tendered as expert opinion evidence is to be admissible, it must be agreed or demonstrated that there is a field of 'specialised knowledge'; there must be an identified aspect of that field in which the witness demonstrates that by reason of specified training, study or experience, the witness has become an expert; the opinion proffered must be 'wholly or substantially based on the witness's expert knowledge'; so far as the opinion is based on facts 'observed' by the expert, they must be identified and admissibly proved by the expert, and so far as the opinion is based on 'assumed' or 'accepted' facts, they must be identified and proved in some other way; it must be established that the facts on which the opinion is based form a proper foundation for it; and the opinion of an expert requires demonstration or examination of the scientific or other intellectual basis of the conclusions reached: that is, the expert's evidence must explain how the field of 'specialised knowledge' in which the witness is expert by reason of 'training, study or experience', and on which the opinion is 'wholly or substantially based', applies to the facts assumed or observed so as to produce the opinion propounded. If all these matters are not made explicit, it is not possible to be sure whether the opinion is based wholly or substantially on the expert's specialised knowledge. If the court cannot be sure of that, the evidence is strictly speaking not admissible, and, so far as it is admissible, of diminished weight. And an attempt to make the basis of the opinion explicit may reveal that it is not based on specialised expert knowledge, but, to use Gleeson CJ's characterisation of the evidence in HG v R (1999) 197 CLR 414, on 'a combination of speculation, inference, personal and second-hand views as to the credibility of the complainant, and a process of reasoning which went well beyond the field of expertise' (at [41])."
55The only evidence Dr Middleton could properly give within his area of expertise was that the positioning of the fractures to the deceased's teeth established that different directional forces from more than one blow caused them. He was unable legitimately to say more than that. Significantly as well, Dr Middleton was not able to rule out that the deceased's teeth could have been damaged in the period between death and burial. His opinion as to the timing of the fractures was ultimately predicated on soil staining of the teeth, not the date of death. It is not in issue that there was a period of some two to three days between death and burial, and that during this period there was rough handling of the body.
56Associate Professor Richard Widmer, who is a paediatric dental specialist rather than a forensic odontologist, gave unchallenged evidence that the dental damage evident on the teeth of the deceased, as depicted in the post mortem photographs, was strongly suggestive of traumatic dental damage. He offered the opinion that it would appear to have happened around the time of the death of the deceased.
57I am unable to find beyond reasonable doubt that the offender relevantly formed an intention to kill the deceased. There is no direct evidence to support such a finding. Such inferences as are available from the evidence are weak or ambiguous. For example, there is evidence of physical abuse of the deceased over an extended period before her death but unrelated to it. Putting aside the fundamental problem with that evidence, that it cannot be established that the offender committed the acts that caused the injuries concerned, the assumed conduct was non-lethal and correspondingly uninstructive upon the question of the offender's intent with respect to the offence of murder. The injuries to the deceased cannot in my opinion be confidently arranged in an order suggesting a chronological increase in severity. Indeed, the particular mechanisms by which they were inflicted are in every case necessarily mired in doubt.
58The mechanism of the death of the deceased is also unknown beyond general and hypothetical terms. My rejection of the offender's version of what happened does not automatically operate to elevate some otherwise available competing hypothesis about it to the requisite level of satisfaction. Indeed, even accepting for the purposes of the analysis that the deceased died as the result of a series of blows to her jaw sufficient to cause the observed damage to her teeth, such an acceptance produces no more than a reasonable suspicion that she was struck in that way in order to cause injury of some sort. It is insufficient, except with the illegitimate benefit of hindsight, with which to reason to a finding beyond reasonable doubt that the injuries were inflicted with an intention to cause death. A significant countervailing inference arises from the fact, which I find on the balance of probabilities, that the offender sought, albeit unsuccessfully, to revive the deceased in the immediate period following the infliction of the ultimately fatal injuries.
59Nor does the apparently fraught physical and emotional relationship between the offender and the deceased reliably inform this inquiry. The Crown has emphasised, for example, that the offender has admitted that she was intending to send the deceased to live with her father. As extraordinary as that proposal may on one view appear to have been, it is not altogether inconsistent with the offender acknowledging that the deceased would be better off if she were moved. It does not come close in my view to assisting a determination of the offender's intentions at some later stage. The same applies to the offender's attempts to conceal the deceased's injuries from childcare professionals employed by the relevant department.
60On the contrary, I am satisfied beyond reasonable doubt that the offender intended to inflict grievous bodily harm upon the deceased when she committed the act that caused her death. I am satisfied that the offender caused such harm, by reason of the combination of the offender's concession that the deceased sustained a severe head injury at her hands, and the evidence of damage to the deceased's teeth referred to by Dr Middleton and Dr Orde. I have formed that view upon the basis that the force required to cause the injuries described by these doctors was only consistent with an intention to cause really serious injury. I am confirmed in arriving at that finding by the fact that more than one blow was administered to the deceased. An attack upon a six-year-old child with that amount of force is wholly inconsistent with the existence of an intention to cause less than really serious injury. I am satisfied on the balance of probabilities that no more than two blows were inflicted.
