Matters sought to be relied upon as incriminating conduct
The prosecution submits that the above conduct is capable of being regarded by the jury as conduct amounting to an implied admission by the accused in seeking to avoid detection and apprehension that the accused had committed a serious violent criminal offence against Shari Grey for which he knew he had no lawful defence or excuse.
conduct means the telling of a lie by the accused or any other act or omission of the accused, which occurs after the event or events alleged to constitute an offence charged;
incriminating conduct means conduct that amounts to an implied admission by the accused -
a) of having committed an offence charged or an element of an offence charged; or
b) which negates a defence to an offence charged;
offence charged includes any alternative offence
The prosecution must not rely on evidence of conduct as evidence of incriminating conduct unless -
(b) the trial judge determines that, on the basis of the evidence as a whole, the evidence of conduct is reasonably capable of being viewed by the jury as evidence of incriminating conduct.
(1) If the prosecution relies on evidence of conduct as evidence of incriminating conduct, the trial judge must direct the jury that -
a) The jury may treat the evidence as evidence that the accused believed that he or she had committed the offence charged or an element of the offence charged, or that he or she had negated a defence to the offence charged, only if it concludes that -
the conduct occurred; and
the only reasonable explanation of the conduct is that the accused held that belief; and
b) even if the jury concludes that the accused believed that he or she had committed the offence charged, it must still decide, on the basis of the evidence as a whole, whether the prosecution has proved the guilt of the accused beyond reasonable doubt.
illuminate the task of the trial judge in making the determination under s 24(1)(b). Thus, in determining whether the evidence 'is reasonably capable of being viewed by the jury as evidence of incriminating conduct', the judge is deciding whether it would be reasonably open to the jury to conclude that:
The question in any case whether a jury should draw a particular inference is of course essentially a question of fact for the jury and not for the judge. It is not my task to determine whether the jury should draw the inference contended for by the prosecution. Rather at this stage my task is to determine whether the jury acting rationally could conclude that the only reasonable inference from the post-offence conduct indulged in by the accused is that contended for by the prosecution. (See R v Cengiz).
Thus where the prosecution seeks to rely on post offence conduct, the test for myself as the trial judge is whether the jury could rationally conclude that the only reasonable inference to be drawn from that conduct is that contended for by the prosecution, namely, an awareness that she had murdered her daughter-in-law and was not acting in self-defence; see R v Ciantar; the Jury Directions Act 2013 s 25(1)(a)(ii)
Further, the test which I must consider is not whether standing alone the only reasonable inference to be drawn from that conduct is that the accused acted as she did, because of a belief that she had murdered Selina Lin without justification. Rather it is plain that that question must be considered in the context of all the evidence in the case, and the background circumstances to it. (R v Ciantar; Jury Directions Act 2013 s 24(1)(b). [6]
Accordingly, in the present case, in determining the admissibility of the evidence relating to the siege, the judge was required to determine whether the jury could rationally conclude that the only reasonable inference to be drawn from the applicant's conduct in relation to that siege was that contended for by the prosecution, namely, that he knew that when he stabbed Stevens he had intended to kill him or cause him really serious injury, and that he did not believe that he acted in lawful self-defence in doing so.[8]
In our view the argument cannot be sustained. For even allowing that a possible explanation of the applicant's post-offence conduct was that he was conscious that he had committed one or more of the lesser offences, as opposed to the offence charged, it does not follow that the post-offence conduct could not be left to the jury as something which was capable of supporting an inference that the applicant was conscious that he had committed 'the offence charged'.
We accept that there may be some circumstances in which post-offence conduct is equally consistent with two or more possible offences or is otherwise intractably neutral. Where that is so, it may not be open, even on the totality of the evidence, to draw the inference that the accused had a consciousness of guilt of some particular conduct at the time that he told lies or performed some act which the prosecution relies upon as constituting post-offence conduct. But where such lies or conduct are considered in the context of all of the evidence it is not to be assumed that it will usually be so. Indeed, in the scheme of things, it is not likely to be so in many cases. And, to the extent that Heyes implies the contrary, in our view it should not be followed.[11]
It is clear from the statutory provisions that the decision of a trial judge pursuant to s 20(1)(b) does not concern the admissibility of evidence but rather the manner in which evidence may be used. That is, the judge must determine whether the evidence is reasonably capable of being viewed by the jury as evidence of an implied admission by the accused of having committed an offence charged, an element of an offence charged or negating a defence to an offence charged. That determination must be based on the whole of the evidence. It involves no determination of whether the jury would so view the evidence, only whether the jury could do so. In accordance with the mandatory s 21(1)(a) direction, the jury must be directed that the evidence of conduct may only be treated as evidence of incriminating conduct if the jury concludes that the only reasonable explanation of the conduct is that the accused believed that s/he committed an offence or an element of an offence charged or negated a defence to an offence charged.
Under s 20(1)(b), the judge has a gate-keeper role. The central issue is the capacity of the evidence to found a process of reasoning. The judicial determination that the evidence has the relevant capacity is a necessary pre-condition to the later determination by the jury whether or not to adopt that reasoning, subject to the mandatory direction in s 21(1)(a). Section 20(1)(b) is a broad filter as to whether the evidence is fit for the jury's consideration as an implied admission of guilt. Section 21(1)(a) constrains the jury in how that consideration is performed.
The combination of these provisions indicates that the JDA contemplates that post-offence conduct evidence may be presented to the jury as evidence of incriminating conduct of the offence charged that ultimately may not be able to be treated as such by the jury because there are other reasonable explanations for that conduct. In other words, evidence of conduct explicable by more than one reasonable argument will, usually, pass through the gateway in s 20(1)(b).[14]
24 Having set out a passage from Scriven, the Court stated:
Thus the s 20(1)(b) question is not whether the only reasonable explanation for the conduct is that the accused believed he or she had committed the offence charged, but, rather, is another explanation one which the jury could accept or reject as reasonably possible. If so, the evidence must pass through the gateway. It is then for the jury to determine whether, on the evidence as a whole and bringing its collective life experience, wisdom and common sense, it accepts or rejects the reasonable possibility of the non-incriminating or alternative explanation.[15]
25 Describing s 20(1)(b) of the JDA as a 'broad filter', the Court observed:
Neither the Zhuang nor Scriven formulation of the s 20(1)(b) determination should be read to suggest that the judge is to determine on the evidence or lack of it whether the jury should reject the non-incriminating explanation. As we have stated, given the relationship between the s 20(1)(b) judicial determination and the s 21(1)(a) mandatory jury direction, the JDA contemplates that conduct evidence will be presented to the jury as evidence of incriminating conduct of the offence charged but ultimately not treated as such by that jury. Where the conduct is capable of reasonable explanation either as a belief in manslaughter or a belief in murder, the question must be left to the jury, save for the unusual case, not this case, where the conduct is equally consistent with both explanations and there is no other evidence that bears upon the issue.[16]
The way it's framed in Lynn is, is the alternate explanation the one consistent with innocence, or inconsistent with incriminating conduct reasoning, does that arise on the evidence firstly, secondly, is it capable of rejection, capable of acceptance, if it's just in that sort of neutral category, well the gateways are passed, but if Your Honour identifies the jury would not be in a position to reject that innocence explanation, then the gateways are not passed.
