1. The defendant in this case runs three defences. Provocation and diminished responsibility have been highlighted expressly by the parties in their opening addresses to the jury. But in his evidence, the defendant has said that he did not intend to kill the deceased, that the killing was a mistake. I therefore intend to leave to the jury also manslaughter by an unlawful act.

1996, No. HC 404 ------------------------ H E A D N O T E ------------------------ Criminal law ( Homicide ( Diminished responsibility ( disease of the mind ( extreme emotional arousal in a defendant who, before the killing, was not suffering from abnormality of mind (- psychiatric evidence that extreme arousal was a disease of the mind ( whether, however, the evidence could in law justify a verdict of manslaughter on grounds of diminished responsibility ( relationship to defence of provocation. A defendant charged with murder put forward the defences of provocation and diminished responsibility, saying he killed the deceased when in extreme rage. Before the incident he suffered no abnormality of mind, whether induced by disease or otherwise. Psychiatric evidence called on his behalf was that at the time of the killing he suffered a transient abnormality of the mind which substantially impaired his mental responsibility for his action. The disease of the mind was said to be a "state of extreme emotional arousal characterised by the emotions of extreme rage and panic." Held: 1. The ipse dixit of a psychiatrist was not in itself conclusive of the issue whether there was sufficient evidence to be left to the jury that a condition was a disease of the mind within the meaning of section 3 of the Homicide Ordinance. 2. Section 3 was concerned with exceptional and abnormal underlying causes peculiar to an individual, and not with the reaction of an ordinary person to an abnormal situation. 3. The condition described by the psychiatrist was not a disease of the mind contemplated by the section. To extend the section to cover the condition described by the psychiatrist would serve to allow in through the back door the evidence of psychiatrists upon straightforward issues which, within the boundaries of the defence of provocation, were well within the competence of juries to decide. 4. Accordingly, there was shown no foundation for the defence of diminished responsibility, and the issue would be withdrawn from the jury, leaving it to consider the defence of provocation. 1996, No.HC 404 IN THE HIGH COURT OF HONG KONG COURT OF FIRST INSTANCE (CRIMINAL JURISDICTION) ---------------
--------------- Coram : The Honourable Mr Justice Stock in Court Dates of Trial : 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 and 25 July 1997 Date of Ruling : 23 July 1997 ----------------- R U L I N G ----------------- The Issue 1. The defendant in this case runs three defences. Provocation and diminished responsibility have been highlighted expressly by the parties in their opening addresses to the jury. But in his evidence, the defendant has said that he did not intend to kill the deceased, that the killing was a mistake. I therefore intend to leave to the jury also manslaughter by an unlawful act. 2. The question which now arises is whether a foundation has been shown upon the evidence that the accused was suffering from a state of mind which was abnormal, and if so, that such abnormality was due to one of the specified causes, in this case disease of the mind. In other words, is that which the doctor has said such as amounts to evidence upon which if accepted, a jury could be justified in returning a verdict of manslaughter based on diminished responsibility. If so, I must leave that issue to the jury, and my own view as to the perversity or otherwise of such a verdict would be irrelevant. 3. The issue is one which I have raised of my own motion. I have been troubled to ensure that the parameters of the section are not abused; and troubled by considerations of how in the circumstances which have arisen in this case, I would direct the jury about the ambit of the term "disease" in section 3 of the Homicide Ordinance. 4. In the light of the contentions which have been put forward by the medical evidence, if in fact the directions which I were to give to the jury were to make clear that the condition described by Professor Wong was not within the contemplation of the section, what then, one is bound to ask, is the point of leaving the decision to them? It would mean that counsel, especially counsel for the defence, would be seen to address the jury, perhaps at length in respect of a defence which the trial judge was then going to say, either in terms or by clear implication, was no defence at all on the facts. 5. The third alternative was simply to leave the matter to the jury on two contending accounts by the psychiatrists alone, one that was saying that the condition was a disease of the mind, the other saying it was not, and asking the jury to sort that out on their own without guiding them as to the meaning of disease. This course did not, nor does it, appeal to me for if it is clear that the condition described is not one which falls within the section, then it is a matter which must be tackled and not left in the air. 6. Furthermore, if the correct conclusion is that the condition in question is not one contemplated by the section, then it is better that it be made rather than that there should build up some habit of running such defences in every case where provocation is put forward as a defence. 7. So I raised with counsel two issues. Was there sufficient evidence to warrant leaving the defence of diminished responsibility to the jury, and if so, what was it suggested I should say about the meaning to be attributed to the word "disease"? 8. I yesterday invited counsel to address me on these points and they have done so this morning. The background, put very broadly, is this. Factual Background 9. The defendant has said that the killing was a combination of frustrating and infuriating behaviour by the deceased. I shall not rehearse the facts or allegations in full. But suffice it to say for present purposes he was a married man separated from his wife, but had been conducting a clandestine relationship with the deceased for some months, a relationship which he was most anxious to keep from his family and from the villagers in the village where he lived. She was an addictive gambler. He says that he had been a gambler, but he had decided to turn over a new leaf and had been urging her, to no avail, to do the same. She wanted to marry him and move in with him but this he was not disposed to do, at least until their debts were sorted out. 10. On the fatal night in question, she came to his home in the village and there developed a row. They argued about a number of matters including her gambling and her failure to obtain employment. And she began to shout and abuse him and accuse him of selfishness. She was shouting and he was very angry. He says he grabbed her by the neck because he wanted to stop her from shouting and he was terrified that the neighbours would hear. The row continued. He discovered she had been to Macau and he thought that she had spent the $50,000 which she had so recently borrowed to pay off some debts. And he put his hands around her neck again. 11. He said in evidence that he had never been so angry before in his life. He let go of her neck. She threatened to reveal to others his affair with her, as well as to reveal a secret which was very dear to him and that he had revealed to nobody else and that he was most anxious that no one, especially his parents, would know about, namely, his wife's former status as a divorcee. 12. He said in evidence, "I was in extreme rage. I did not know what to do. I gripped her neck trying to stop her from shouting. I do not know why I continued to grip her neck. The main purpose was to stop her from shouting further." After the killing he sat for an hour, not knowing what to do. He called no help because, he says, he feared being locked up. In other words, he feared being found out. He also says that he did not intend to kill her. The Psychiatrist's Evidence 13. I now turn to the evidence of the psychiatrist. There was much of it and I certainly do not intend to go through it all. I hope that it is not unfair to summarise its effect in this way. 14. The defendant was, before the incident, normal in the sense that he suffered from no abnormality of mind nor any disease of the mind. He suffered from no personality defect, no paranoia, no psychosis, no brain damage, no chronic alcoholism, no form of depression, clinical or otherwise. Nor was there any such illness after the event although Professor Wong did say that there were probably two or three hours after the killing in which the state of extreme arousal, to which I shall shortly come, continued. He assumes, as he had to, that the account given to him by the defendant was true. What happened, he said, was that the two of them found themselves in an occasion of mutual accusation and provocation. 15. In his first written report at paragraph 37, he says that the deceased again had stated her wish to move into Mr Leung's village home. This was an absolute taboo for Mr Leung. The deceased responded to Mr Leung's refusal by more complaints and accusations. The anger between them escalated very quickly. Mr Leung grasped the deceased's neck and asked her if she had been gambling again. In turn the deceased, in the anger of the moment, resorted to using very simple but highly effective and destructive strategy to hurt Mr Leung, screaming loudly in the middle of a very quiet village night. The preceding quarrel and struggle, aggravated now by the deceased's screaming, quickly stirred up a state of extreme panic and rage in Mr Leung. The state of extreme panic and rage led to transient but very severe abnormality of the mind. Under this transient but very severe abnormality of the mind, Mr Leung used the only effective means he had at his disposal to quiet the deceased; he used his two hands which were already positioned over the deceased's neck to stop her from screaming. "The very deplorable thing was that he went beyond stopping her from screaming; he lost control of himself and killed her." 16. And at paragraph 38 which is in concluding paragraph, he says:
by which, no doubt, Professor Wong had in mind the same terms couched in section 3 of the Homicide Ordinance in Hong Kong. 17. There is in that report no express reference to disease of the mind. The absence of such express reference continued until the production of the Professor's report dated 10 July 1997 on the very eve or at the very of beginning of trial, and at a stage after there had been canvassed questions of the admissibility of his evidence. 18. He then said in that report that:
He explained in his oral evidence, with the aid of literature, that at extremes of hyper-arousal, people become disorganised and lose the ability to control themselves. 19. Thus far, I am bound to confess that it was difficult to see any distinction between what had been said and the defence of provocation. Provocation is conduct which would cause in any reasonable person and actually causes in an accused sudden and temporary loss of self-control, making him so subject to passion that he is not the master of his mind. But I return to the evidence. 20. In his oral evidence, Professor Wong went on to say that the abnormality of mind was manifested by extreme emotional rage and panic. He was not talking about ordinary rage and panic, he was talking about something more extreme, much more extreme. It was something so powerful as to overcome normal emotional rationality, for example, such as not to harm loved ones. The threat to reveal a secret was a special factor here. It augmented, as I understand the intent of his evidence, the degree of panic. 21. The extreme arousal, he said, was a transient, severe abnormality which the usual psychiatric classification system did not define as a disease because that classification, or those systems of classifications, tend to deal with the longer lasting states. The fact, however, that there was no classified name for this disease did not alter the nature of the creature. The state of extreme arousal, he said, was a psychiatric disorder and it actually persisted after the killing, until and including the time dismemberment occurred. 22. He thought it lasted after the killing when the defendant was cutting up the body but it did not last while the defendant stole the deceased's money later that day, nor presumably in the subsequent four days, nor when he cut off her legs 24 hours or so after the killing. The Professor thought that it lasted for two or three hours. It's root was in the limbic system and he described how that system can be stimulated by emotions to the condition in which the defendant found himself. 23. I pause to comment that the real question, so it seems to me, is not whether the brain or the limbic brain is stimulated by emotions but whether it is stimulated by disease. 24. Be that as it may, the Professor went on to say that the events which the defendant described led to rage and panic, which in turn led to this transient abnormality of the limbic system. That was the disease. The propensity to come into this state of mind is inherent in the human mind. Underneath human behaviour were physical explanations, and under such behaviour lay the function of the brain. There was a neurological explanation for the state of hyper-arousal. 25. He then spoke of this defendant having no prior propensity to violence, such people needing particularly high stimulus to break that non-violent mode. He concluded in-chief by saying that in his opinion the abnormality was induced by a disease which was extreme arousal, a recognised psychiatric state. 26. I pressed the matter in questions which I put to the Professor, for it appeared to me that this was nothing more than a defence of provocation, and if the Professor was saying that all losses of self-control due to provocation constituted diminished responsibility, it begged the question as to whether that as a matter of law could be right. Could the section ever have contemplated this development? Was I being asked to stretch the section to new levels never intended? 27. The answer to my question was in effect, indeed, in terms, "yes". The exchange between the Professor and myself went as follows:
In other words, what he was saying was that the loss of self-control in that situation equated to a disease of the mind and diminished responsibility. 28. Now, Dr Lui gave evidence for the prosecution. I do not intend to deal with that evidence in any detail for the real question I have to address is the effect, not of his evidence, but the effect and parameters of Professor Wong's evidence. It suffices to say that Dr Lui disagreed with Professor Wong, and the disagreement could not have been more stark. He interpreted Professor Wong's evidence as suggesting that anger or extreme anger was a disease of the mind. It was, said Dr Lui, no such thing and he had never heard such a suggestion, save where anger was induced by recognised disease such as paranoid schizophrenia. 29. What Professor Wong had been addressing, as far as Dr Lui was concerned was, limbic system included, the normal functioning of human beings and he asserted that arousal and such like emotions were part and parcel of normal human emotions. Intense emotions were within the nature of man and were not per se diseases. The defendant suffered, as far as he was concerned, no disease of the mind, whether at or before the killing. The Law 30. I turn now to the law. Section 3 of the Homicide Ordinance provides as follows:
It then goes on to provide, subject to the question of the onus of proof, that a person who but for the section would be liable to be convicted of murder shall be liable instead to be convicted of manslaughter. 31. A number of matters, it seems to me, are clear. It is not sufficient to show that the defendant suffered at the material time from an abnormality of the mind. It is vital that it should be shown that that abnormality was induced by disease or by one of the other causes specified by the section. That list of causes is exclusive. It must be shown that the abnormality was caused by a condition of arrested or retarded development of mind or inherent causes or induced by disease or injury. 32. That list in itself provides the flavour of and the rationale for the section. The thinking behind the section was one directed at moral responsibility for the act of a defendant. As it is put in Smith v. Hogan, Criminal Law, 7th Edition, page 213:
33. The section, in my judgment, is directed primarily if not exclusively at an understanding and sympathy for those who are vulnerable through inherent or diseased causes peculiar to themselves, even if the disease happens to manifest itself temporarily or spasmodically, but the section is not designed to cover the normal person behaving abnormally through drink, or through jealousy, or frustration, or anger. Such conduct may be covered by other defences such as provocation, but not, in my judgment, by this defence of diminished responsibility. 34. I comment in passing that Mr Forrest, for the prosecution, in addressing me today, pointed out that the defence does apply for the benefit of an alcoholic. That may be so in certain cases, but the law, as I understand it, is that an abnormality of mind induced by alcohol is not of itself an abnormality induced by disease. (See Gittens, [1984] QB 698.) Although if the imbibing of drink has reached the stage that the accused's brain has been damaged so that there is gross impairment of judgment and emotional responses, or the accused's use of alcohol is involuntary because he can no longer resist the impulse to drink, the defence of diminished responsibility is available. (See Halsbury's Laws, paragraph 440, and the notes thereto.) 35. Now, it does not appear to me to be sufficient in order to leave a matter of this kind to the jury for the court to rely without more on the ipse dixit of the psychiatrist that a condition is or is not a disease of the mind. It is, in my judgment, for the court to determine whether there is evidence that there is a condition which is a disease of the mind, as that term is comprehended by the legislation, and that approach cannot be altered merely by the psychiatrist saying that the condition has its origins in the brain, or in that part of the brain that controls emotions and reactions to those emotions. That much might be said of the effect of drink or passion, or of any human reaction to any external influence. 36. In R. v. Kemp, [1957] QB, 399, Devlin J, as he then was, said at page 406:
37. The effect, so it seems to me, of Professor Wong's evidence is this: he is saying that the defendant, a normal person without a predisposition to violence, but without any psychiatric illness or personality disorder, was so aroused by passion that he lost his self-control suddenly and temporarily; that this extreme state of passion and arousal constituted or was manifested by a disease of the mind which has no name. 38. He referred me to texts which describes stimuli to the brain, which stimuli can produce rage; this in the context of a full discourse on the functioning of the limbic brain. The text to which he refers gives examples of such stimuli: electric stimulation, head injury and a tumour. Those examples, it seems to me, far from supporting the suggestion that the defendant's reactions were diseased, as that term is contemplated by the section, highlighted precisely that which section 3 is designed to protect and that which it is not. 39. It is concerned with stimuli such as tumours and head injuries; in other words, exceptional and abnormal underlying causes peculiar to an individual and not with the reaction of a normal man to an abnormal situation. In the case of Porter (1936) 55 CLR 182, Dixon J, as he then was, directed a jury as follows (page 188):
40. And in the case of Carter [1959] VR 105, reference was made to an address by Dixon CJ, as he had by then become, and Sholl J summarised the salient passages thus, at page 108:
41. It seems to me that what the Professor is saying in this case is no more than that the defendant was suffering at the material time from intense passion, and that his brain in that condition caused him to behave as people in states of intense passion will behave, and he seeks then to describe that condition as a disease or a manifestation of a disease which he is prepared to call a state of extreme emotional arousal. 42. Although it is urged upon me that what he is saying is that there was here a state of extreme passion and not just passion, the reality is that what is being described is that condition of an ordinary man contemplated by the defence of provocation; in other words, a sudden and temporary loss of self-control which any reasonable person would suffer or may suffer, having been provoked by words or actions, thus making him so subject to passion that he is not the master of his mind. 43. It has nothing really to do with this defendant at all in the sense that there is or was nothing peculiar to him that produced that condition. It is inherent in all of us. It is a condition of intense passion which Dixon CJ suggested, and I most respectfully agree, is not a condition which is contemplated by this section or sections with essentially the same wording as a disease of the mind. Indeed, Mr McLanachan this morning conceded, as I think he was bound to do, that it was not being suggested that the condition in this case amounted to anything more than would justify a finding of manslaughter by provocation. In any event, if there is something beyond that, I pause to make this remark : that if a reasonable man would not have reacted as did the defendant, and provocation therefore does not run, how can it then be a defence of diminished responsibility for the defendant to say, "But I lost my control to a degree greater than the reasonable man", unless he says that he did so because of some pre-existing disease or disability? 44. What Mr McLanachan says is that there is no reason in logic why the two defences of provocation and diminished responsibility, predicated on the same factual basis, should not run together, which I suppose to mean, if he is right, that they can always now be run together. 45. I do not agree. If it is right to say that the very use of the phrases in the section are such as are intended "to exclude drunkenness, conditions of intense passion and other transient conditions attributable to the nature of man", then it seems to me that it is right in this case to exclude the state of extreme arousal from the grasp of the section, for what we are talking about in this case is an allegation of loss of control because of intense anger or passion, and to say that the section embraces that condition or can embrace that condition as a disease of the mind is to extend the arena in which that section was placed, to cover conduct by normal people in situations for which the section and its rationale was never intended. 46. Insofar as it might be said that there ought surely to be some recognition by the law of a lesser culpability for those who are in a state of extreme arousal by reason of things said and done, and who in such circumstances lose their self-control, the answer is that there is such recognition and it lies in the defence of provocation. The professor's arguments, with respect, add nothing to that defence. 47. To extend section 3 of the Ordinance to cover the same ground is not only to distort the section, but it is also unnecessary and can serve only to confuse. It would also serve to allow in through the back door the evidence of psychiatrists upon straightforward issues which, within the boundaries of the defence of provocation, are well within the competence of juries to decide. 48. Accordingly, in my judgment, the section does not cover and cannot cover the condition which the Professor has described, and in my judgment therefore there is shown no foundation in this case for the defence of diminished responsibility. 49. I have given some thought to the proper approach to take, namely, whether to withdraw the issue from the jury and tell them that they are not to consider it, or whether to tell them, in the course of summing-up, merely that the state of extreme arousal is not, in law, a disease of the mind. To withdraw at this stage this defence after it has been canvassed for so long before the jury carries with it a tactical danger; tactical, I mean, in terms of the interests of the defendant. It might be thought that there was a danger that by doing so the impact will somehow undermine the efficacy of the defence generally, and of the defence of provocation in particular. 50. Mr McLanachan prefers me to take the bull by the horns and withdraw the matter, which is not to say, of course, that he accepts the merits of my decision on the law. I think he is right, with respect, for it otherwise places him in an impossible position as far as concerns his speech to the jury, and merely delays such impact as my view of the law which I am bound at some stage to convey will have when ultimately I do express it. 51. I shall use an appropriate formula to press home to the jury that my decision is not one which attacks the evidence of the Professor on the merits, but which addresses the question whether his evidence amounts to or can amount to diminished responsibility within the law as the law is framed, and I shall emphasise how important it is that they should recognise the fact that the defence of provocation stands fully before them and is entirely unaffected by my ruling.
