However, the duty imposed upon the court by this section applies whether or not an objection is raised to a particular question.
27 This is a clear indication, if any be needed, that Parliament understood that courts would not generally be under an obligation to reject a question to which no objection was taken and did not intend generally that other obligations imposed upon a trial judge in relation to the admission or reception of evidence would apply except where an objection is taken to the evidence. Section 275A can be compared with s 41 of the Evidence Act, which does not apply to criminal proceedings, that permits a court to disallow an improper question but does not purport to impose a duty on a court to do so irrespective of whether objection is taken to the question.
28 With respect, we find the argument contained in paragraph 20 in the judgment of Dhanhoa set out above compelling in rejecting the notion that, generally speaking, a trial judge should take upon himself or herself the role of determining the admissibility or reception of evidence to which no objection is taken by a lawyer representing an accused person. There may be provisions that unambiguously impose such an obligation on a court by the wording of the section, for example s 275A, or by reason of its subject matter; for example provisions concerned with the exclusion of evidence in the public interest such as s 130. But we do not believe that s 137 falls into either of those categories and therefore, imposes an obligation on a trial judge to reject evidence of his or her own motion where no objection is taken and the accused is legally represented. There may be exceptional situations where a trial judge is compelled to intervene in order to prevent a miscarriage of justice, but there is in our opinion no provision of the Evidence Act that requires such intervention.
29 So far as s 137 is concerned, we do not understand how a trial judge could reliably undertake the balancing exercise that the section requires between the probative value of the evidence and the danger of unfair prejudice without a complete understanding of both the Crown and defence cases and the arguments to be addressed to the jury by the parties. Yet the section is engaged when the Crown first introduces the evidence that is later impugned in this Court. This difficulty is alone sufficient to lead us to the conclusion that s 137 cannot operate to oblige a judge to reject evidence that may later be seen in the context of the whole of the trial to have resulted in a miscarriage of justice.
30 Strictly speaking it was unnecessary for the Court in Steve to determine the issues raised by construing s 137 as it did. However, nothing we have written is to be taken as suggesting that the decision was in any way erroneous in finding that the trial miscarried by the reception of the evidence in the circumstances of that particular case. Nor does it necessary follow that a miscarriage of justice would not have been found had r 4 been applied. However, we respectfully disagree with the finding that the miscarriage of justice arose from the failure of the trial judge of his own motion to reject evidence to which no objection had been taken by the solicitor for the defence.
Did a miscarriage arise in the present case?
31 The present appeal can be determined on the basis that r 4 applies and, therefore, the onus is upon the appellant to show to the Court how, in the absence of objection from an apparently competent defence counsel, the admission of the evidence as to what happened on 16 July or the making of the ADVO led to a miscarriage of justice.
32 It should be noted that the defence put forward by the appellant was not without some difficulties for defence counsel. According to the appellant it was the complainant who brought the knife to the park and threatened him with it. Yet it was the complainant who ended up with a not insignificant stab wound to the shoulder as well as some other minor injuries. Rather than complain to the police about the complainant's behaviour, the appellant took the children to Canberra. The common experience of the jury might, at least to a prima facie view, lead them to believe that the person who produces a knife is not likely to be the person who is injured by it. Particularly, where as here, the appellant was saying that the complainant in effect managed to wound herself. The evidence of the treating surgeon was that it was unlikely to have been self-inflicted.
33 The appellant stated that the Crown case depended upon the evidence of the complainant and that the jury were directed that they needed to be satisfied of the complainant's evidence beyond reasonable doubt. However, there was some support for the complainant's account in the evidence of the persons who came upon the scene and the complainant's statement to them that her husband had stabbed her. This was evidence admissible under s 66 of the Evidence Act as hearsay evidence and was available to the jury as evidence of the truth of what the complainant asserted. In our opinion the jury would clearly have recognised the probative value of that evidence, even though there was no direction to this effect given by the trial judge. There was also a Triple 0 call made by the complainant shortly after the incident that the Crown sought to use to support the truthfulness of her account. This material would not have made defence counsel's task any easier in seeking to raise with the jury the reasonable possibility that the complainant produced the knife and wounded herself.
34 The submission on behalf of the appellant is that the combined evidence of the incident occurring on 16 July and the making of the ADVO presented the jury with evidence of a court order restraining the appellant from violent conduct toward the complainant. The argument is that this evidence "negated the impact of the evidence of good character" led by the appellant and it supported the complainant's account of the incident of 2 August by suggesting that the appellant had "a propensity to behave in a violent or threatening manner to the complainant".
35 The submission was made that the evidence of the incident on 16 July and the making of the ADVO was irrelevant to any issue before the jury especially in light of the fact that the appellant had pleaded guilty to the offences in relation to his abduction of the children. It was further submitted that the evidence of what occurred on 16 July was "akin to evidence of uncharged criminal conduct" and hence gave rise to the concerns expressed by members of the High Court in HML v The Queen [2008] HCA 16; 82 ALJR 723. It was argued that the ADVO gave "explicit support to the uncharged conduct and the account of the complainant".
36 In our opinion the evidence of what occurred on 16 July and the making of the ADVO was clearly relevant to what occurred thereafter including the incident on 2 August. It was an example of background or context evidence that explained why the parties did what they did and said what they did both before and on the 2 August. It set the scene for the incident that gave rise to the charges. For example, the evidence explained why the appellant could not have direct contact with the complainant or the children and the arrangements that had to be made for his access to the children through the complainant's parents.
37 It is the type of evidence that was recognised at common law in a series of cases including O'Leary v The King (1946) 73 CLR 566; Wilson v The Queen (1970) 123 CLR 334 and Harriman v The Queen (1989) 167 CLR 590. Such evidence has been admitted as evidence either of the relationship between the accused and some other person or of a connected series of events such that what occurred at one particular point in time in that relationship or in that series of events was relevant to a determination of what occurred at another point in time when the offence was committed. This type of evidence continues to be admissible under the Evidence Act: R v Quach [2002] NSWCCA 519.
38 The kind of evidence considered in HML, that is evidence of allegations of uncharged sexual activity between the complainant and the accused, is derived from this type of evidence but has its own peculiarities such that it has been treated with considerable circumspection by the courts. This is because its potential to prejudice the accused is extremely high and because of the difficulty in circumscribing the use to be made of the evidence to avoid it being used improperly as propensity evidence when it is not tendered for that purpose. It is the grave potential for prejudice arising from that kind of evidence that has resulted in special rules being adopted by some members of the High Court for the introduction and use of that evidence. For example it appears now to be the law that, if that type of evidence is to be used by the jury for tendency reasoning, it must be proved beyond reasonable doubt; see DJV v R [2008] NSWCCA 272. There has been no suggestion that any other type of propensity evidence has to be proved to that standard.
39 However the category of evidence into which the events of 16 July and the making of the ADVO fall has never been considered as propensity evidence even though it is admitted to explain the conduct giving rise to the criminal charges by reference to conduct on another occasion. Nor has it ever been seen to carry with it the type of prejudice that has accompanied the introduction of uncharged sexual activity in child sexual assault cases. In the present case, unlike evidence of the type considered in HML, there can be no concern that the jury could reasonably have used the evidence for propensity reasoning. The Crown in opening described it as "background". It was never elevated to anything more than that either in addresses or in the summing up.
40 However, the incident on 16 July was also clearly relevant to the major issue before the jury: who of the appellant or the complainant might have brought a knife to a meeting between them in the context of the ongoing matrimonial disharmony? If the jury accepted the complainant's account of the incident on 16 July, the statement attributed to the appellant about men feeling like killing their wives and children was obviously of significance in this regard. The only prejudicial aspect of the evidence was that it was probative of the prosecution case that the appellant produced the knife. It was evidence as to the appellant's state of mind arising from his marital problems at a time relatively proximate to the incident the subject of the trial.
41 Had the appellant's wife been found stabbed to death and the question of who was responsible had been the issue before a jury, it would clearly be relevant that a short time before the killing the appellant was expressing the thought that her conduct was capable of provoking a man to kill his wife and family. So too in the present trial it was relevant in the determination of the prosecution allegation that the appellant stabbed the complainant even though ultimately the jury found that he did not intend to inflict grievous bodily harm. But, although relevant, it was not propensity evidence. It was simply evidence of the appellant's reaction to his marital problems that were continuing up until the time of the incident giving rise to the charges.
42 In this regard we do not believe that the making of the ADVO order impermissibly or unfairly bolstered the credibility of the complainant's account of the incident on 16 July, especially when the jury was made aware that the appellant had consented to the order "without making any admissions". That phrase was used a number of times during the course of the trial. In opening the Crown said:
