At the trial, the accused admitted the criminality of the killing. A plea of guilty of manslaughter was formally proffered. The case for the accused was simply that the killing was accidental in the sense that he had not intended to discharge the sawn-off rifle which he had loaded and with which, with the safety catch off and his finger on the trigger, he was threatening Taylor in the course of robbing him. On the basis that the killing was accidental, counsel for the defence invited the jury to convict the accused of manslaughter but to acquit him of murder. As to this main issue, the learned judge said: "It has been pressed on you by Mr. Isaacs that you will find a verdict of manslaughter. To kill a person while doing an unlawful act even if one kills him by inadvertence or by accident, is manslaughter. To present a loaded firearm, point a loaded rifle at the back of a person and if it goes off by accident when you have the loaded firearm at the back of the other person, is manslaughter. Mr. Isaacs has pressed on you that the whole of the evidence here will lead you to that conclusion." This direction may have been too favourable to the accused if the "unlawful act" referred to were armed robbery and if it were to be found that the accused killed Taylor while committing a crime punishable under s. 98 of the Crimes Act or if the act causing the death was done during, or immediately after, an act of the accused obviously dangerous to human life; but these particular problems I put on one side for the present, for my immediate aim is simply to ascertain what was the real issue at the trial, as a step towards determining what direction to the jury was necessary to enable them to perform their task. The part of the direction which I have quoted makes it quite clear that there never was an issue whether Taylor had died by an act of the accused; the primary issue was whether the accused had killed Taylor accidentally and, of course, to establish its case of murder the onus was upon the Crown to prove something more than accidental homicide. This the Crown sought to do by inviting the jury to find that Taylor died by an act of the accused done (1) with intent to kill or inflict grievous bodily harm; or (2) with reckless indifference to human life; or (3) during, or immediately after, the commission by the accused of an act obviously dangerous to human life; or (4) during, or immediately after, the commission by the accused of a crime constituted by s. 98 of the Crimes Act. Had there been any issue between the Crown and the accused as to whether Taylor died by an act of the accused, it would probably have been necessary for the learned trial judge to have assisted the jury with some particular direction about what could in all the circumstances be regarded as the act of the accused causing Taylor's death but, as matters stood when his Honour came to charge the jury, it was not, in my opinion, incumbent upon him to do so with any greater particularity than was necessary to apply s. 18 of the Crimes Act in the circumstances of the case. This, I think, was done and I would say that I do not accept the contention of counsel for the applicant that the act causing Taylor's death ought, for the purposes of s. 18 (1) of the Crimes Act, to have been regarded as the mere pressing of the trigger to discharge the rifle. In these circumstances, I think it was not necessary for the trial judge to tell the jury - as it was contended he should have said - that, if merely pressing the trigger were the particular act of the accused which they found was the cause of Taylor's death, then the evidence might well cause them to doubt whether that very act was done either with intent to kill or inflict grievous bodily harm or with reckless indifference to human life. Indeed, I would have regarded such a direction as involving a misdirection. The jury were, of course, told that, before the applicant could be convicted of murder, the Crown had to prove beyond reasonable doubt that the act of the accused causing the death of Taylor was done with intent to kill or inflict grievous bodily harm or with reckless indifference to human life or during, or after, the doing of an act obviously dangerous to human life or a crime punishable under s. 98 of the Crimes Act, and the attention of the jury was directed to the applicant's case that the killing was accidental.
