THE QUEEN
Pleas of the Crown (1803), vol. I, p. 224.] The suddenly formed intention to kill or cause grievous bodily harm in circumstances like those in the present case is only malice aforethought by implication of law, and the circumstances of the illegal attack rebut that implica tion, SO that it is not malice aforethought at all to form that inten- tion under these circumstances. Before the middle of the last century malice aforethought did not necessarily mean intention to kill see Russell on Crime, 10th ed. (1950), vol. 1, p. 568. He referred to Mead and Belt's Case 4 Forster's Case 5.] The respondent relies upon the passage in Cross and Jones, An Intro- duction to Criminal Law, 3rd ed. (1953) art. 124, p. 247: see also Dicey's Law of the Constitution, 8th ed. (1915), Appendix 4, pp. 492 494. The law is accurately, and for the present purposes, completely stated by Lowe J. in his sixth proposition; alternatively, if there is a self-defence occasion, and particularly a violent and felonious attack, and the accused acts beyond the necessity of the occasion, the offence is manslaughter, not murder, unless he was not acting in good faith for his own defence. [He referred to Halsbury's Laws of England, 3rd ed., vol. 10, par. 1382, p. 721.] The test of reason- ableness is a subjective one, not an objective one. [He referred to R. v. Duffy 6; Re Manning 7; R. v. Fisher 8; Russell on Crime, 10th ed. (1950), vol. I. pp. 564, 565, 572 Archbold's Criminal Pleading, Evidence &Practice, 33rd ed. (1954), par. 1647, p. 940 articles by Dr. Glanville Williams and Dr. J. Ll. J. Edwards, (1954) Criminal Law Review, pp. 740-742, 898 Holmes v. Director of Public Prosecutions 9, and R. v. Cole 10.] In all cases of justifiable homicide there must be a reasonable and honest belief by the accused in the necessity of the killing otherwise it would be what Lowe J. described as "malice under colour of necessity". An unreasonable verdict may be set aside by the Full Court on appeal: Criminal Law Consolidation Act 1935-1956 (S.A.), S. 353 (i). The test is: would a jury, if properly directed, have inevitably come to the same conclusion: see R. v. Sheehan 11; Stirland v. Director of Public Prosecutions 12; and Reg. v. Dunbar 13.
