10.3 Sudden or extraordinary emergency
(1) A person is not criminally responsible for an offence if he or she carries out the conduct constituting the offence in response to circumstances of sudden or extraordinary emergency.

10.4 Self-defence
(1) A person is not criminally responsible for an offence if he or she carries out the conduct constituting the offence in self-defence.

85 In any consideration of these provisions, a number of features stand out. Firstly, there is a deal of similarity or repetition in form and phraseology. Secondly there are clear differences between some of the provisions even when similar topics are being dealt with. Normal canons of construction lead prima facie to similar expressions being given similar meaning and different expressions being given correspondingly different operation.
86 Secondly, the topics being dealt with in the statutory provisions have been the subject of a deal of consideration by the courts for centuries. Those responsible for the drafting and passing of the provisions can be expected to have been aware of the issues with which the courts dealt. As the decisions to which the Chief Justice refers make clear, those issues include whether belief or conduct is to judged by objective or subjective tests and, if the latter, whether the characteristics and perceptions of a particular accused should be taken into account. Although in the area of provocation, rather than duress, emergency or self-defence, Stingel v R (1990) 171 CLR 312 and Masciantonio v R (1994-95) 183 CLR 58, are other cases where such distinctions have been the subject of significant consideration.
87 Thirdly, the references in s10.2(2), "he or she reasonably believes", in s10.3(2) "the person carrying out the conduct reasonably believes" and in s10.4(2) "he or she believes" make it clear that at least in the paragraphs wherein those words appear the actual belief of the person mentioned is what is being referred to, not the belief of some other actual or notional e.g. reasonable, person.
88 Fourthly, the presence of the word "reasonably" before "believes" in s10.2(2) and s10.3(2), particularly when contrasted with the absence of that word in s10.4, impose an additional requirement of, or qualification to, the belief of which ss10.2 and 10.3 speak. The person concerned must not only believe but must reasonably believe. The term "reasonably" introduces an element of the objective into the belief. It is not sufficient for the purposes of those provisions that the person unreasonably believes.
89 Fifthly, there is a clear difference in wording between s10.2 and s10.3 on the one hand and s10.4 on the other in that the latter section expressly refers to circumstances "as he or she perceives them to be" whereas there are no such words in the earlier provisions.
90 Sixthly, it would have been very simple for either s10.2 or s10.4 to have been drafted so as to echo the form of the other. One cannot avoid the conclusion that the differences were deliberate.
91 Given these factors, as a simple matter of statutory construction, it is impossible to conclude that when s10.2. and s10.3 refer to "reasonably believes", they contemplate that a judgment as to the reasonableness of belief will take into account an accused's perception of the circumstances, as distinct from those that objectively exist. To hold to the contrary would involve reading into s10.2 and s10.3 words similar to those at the end of the passage I have quoted from s10.4 and obviously deliberately omitted from the earlier sections.
92 In so concluding, I do not ignore the fact that the personal characteristics of a person, whether congenital or resulting from life's experiences, are calculated to influence the formation of any beliefs as to the matters referred to in paragraphs (a) to (c) of s10.2 nor the argument that, once account is taken of the influence of those personal characteristics in the formation of any belief, one may reach a conclusion that the person "reasonably believes".
93 However, given the nature of the matters referred to in the paragraphs mentioned, it does not seem to me possible to differentiate in any satisfactory way, and certainly not in a way susceptible of definition for a jury, between an accused's perception of those matters on the one hand and the process of the formation of belief on the other. Taking the view that, as a matter of construction, an accused's perception of the circumstances, as distinct from those that objectively exist are not to be taken into account, it must follow that such personal characteristics as may influence the formation of beliefs are also irrelevant. The test of the reasonableness of belief under s10.2(2) and 10.3(2) is thus entirely objective.
94 I turn to the issue of whether the summing-up of Judge Ainslie-Wallace, before whom the proceedings which led to this appeal were conducted, adequately reflected the terms of s10(2). The Chief Justice has quoted the relevant parts of that summing-up and I agree with his Honour that the directions given left no avenue for risk that the jury might have adopted a test of what a reasonable person, rather than the Appellant, believed. I agree also with his Honour that it was not necessary for her Honour to direct the jury that it was required to have regard to the personal characteristics of the Appellant and to assess the circumstances as he perceived them to be.
95 I agree with the Chief Justice that the appeal against conviction should be dismissed. For the reasons his Honour gives I agree also with the orders he proposes for the disposition of the appeal against sentence.
