Libke v The Queen [2007] HCA 30 | Case summary

What happened

Justin Patrick Libke, then 39, met an 18-year-old complainant of Asian appearance while both were exercising dogs in a Brisbane park. On their second encounter on a park bench he touched her legs, placed his hand inside her shorts and digitally penetrated her vagina. She did not say "no", did not move her hands from her sides, and on one view turned to face him and opened her legs slightly. Days later he telephoned her at home, ascertained she was alone, attended with a condom, and engaged in penile-vaginal intercourse (count 2), digital penetration and masturbation in her presence (count 3), further attempted intercourse (count 4) and an act accepted by the jury as exposure to an indecent act (count 5). The complainant described pain during penetration and said she told him it hurt; Libke denied anal penetration and said he lost his erection and penetration was only slight. The complainant's evidence-in-chief was given almost entirely by two video-recorded interviews tendered under s 93A of the Evidence Act 1977 (Q). She was cross-examined at length and agreed she had not disclosed her special education, had sexual urges, had invited Libke over knowing sexual activity would occur, and had opened her legs to facilitate digital penetration. Libke gave evidence that she "seemed fine" in regard to her mental health, spoke normally apart from a lisp and accent, conversed about her parents' origins, invited him to bring protection, and appeared confident. He placed her number in his phone under her name to conceal it from his de facto partner.

At trial before Griffin DCJ the prosecutor cross-examined Libke over 44 pages of transcript. The cross-examination was punctuated by comments such as "I'm not buying it", "that doesn't tell us much, does it?", "your evidence is just a tissue of lies", "hopeless asking a question", and suggestions that Libke was inventing explanations about parking his car down the road, talking about moisturiser for a rash, and changing the subject from movies. Questions were at times compound, argumentative, rested on unproved assumptions, cut off answers, and characterised Libke's conduct as dishonest or cunning. Defence counsel made no objection and sought no redirection. The jury convicted Libke of rape on the park count, and returned alternative verdicts of unlawful carnal knowledge of an intellectually impaired person (twice) and exposure of such a person to an indecent act. He was sentenced to eight years' imprisonment. The Court of Appeal (Williams JA and Mullins J, Chesterman J dissenting on the rape count) dismissed the conviction appeal but reduced the sentence to five years, holding that while some prosecutorial comments were gratuitous the cross-examination as a whole did not render the trial unfair and the directions were adequate. On further appeal to the High Court the majority (Gleeson CJ, Hayne and Heydon JJ) held that although the prosecutor's conduct was inappropriate and the trial judge should have intervened, no miscarriage of justice occurred and the directions sufficiently addressed the real issues. Kirby and Callinan JJ would have allowed the appeal, ordered a retrial and quashed the convictions on the basis that the repeated sarcastic commentary, combined with judicial silence, denied procedural fairness and constituted a significant irregularity that could not be cured by the proviso.

Why the court decided this way

The majority reasoned that while the prosecutor's injection of personal opinion ("I'm not buying it", "hopeless asking a question") and use of sarcastic, harassing and compound questions breached long-settled standards restated in Whitehorn v The Queen (1983) 152 CLR 657, the critical statutory question under s 668E(1) of the Criminal Code (Q) was whether a miscarriage of justice had actually occurred. Hayne J emphasised that a criminal trial remains adversarial; counsel may test credibility vigorously where it is in issue, and the absence of objection by experienced defence counsel was relevant though not decisive. The appellant had been able to give his account that the complainant "seemed fine", was confident and had invited the acts. The jury's mixed verdicts demonstrated they had evaluated the evidence count by count rather than being swept by hostility. The comments, though regrettable, did not invite impermissible reasoning or prevent the jury from focusing on whether guilt was proved beyond reasonable doubt. An early judicial reminder to counsel of the need to observe orderly rules would have been desirable but its absence did not, on assessment of the whole record, produce unfairness.

On the directions, the court held that "cognitive capacity to give consent" under s 348(1) is a distinct inquiry from the s 229F definition of intellectual impairment. Expert evidence established the latter, yet the complainant had demonstrated understanding of sexual intercourse, contraception and the invitation to "fool around". The trial judge correctly directed that impairment does not automatically negate capacity and left the live issue as whether she had given free and voluntary consent. No further elaboration was required because the real issues were narrow and no Shepherd direction on circumstantial evidence was necessary. For the s 216(4) defence the majority accepted Gleeson CJ's observation that most beliefs are undisturbed assumptions rather than reasoned conclusions. Libke's evidence that she "seemed fine" was capable of raising the defence on the balance of probabilities; the judge left that exact statutory question to the jury after defining intellectual impairment and reminding them of the onus. Trial counsel's failure to seek further directions reinforced that the summing-up was sufficient in the circumstances. Because no miscarriage arose the appeal was dismissed.

The dissenting judges viewed the same conduct as so repetitive and permeating that it infected the trial atmosphere. They considered the prosecutor's alignment with the Crown case, taunting tone and failure to allow complete answers deprived Libke of a fair trial according to law. Judicial non-intervention compounded the problem. Even though the evidence could support conviction, the significant denial of procedural fairness meant the proviso could not be applied; a retrial was required to vindicate proper standards.

Before and after state of the law

Before Libke the law on prosecutorial conduct was settled by Whitehorn v The Queen, which required prosecutors to act with fairness and detachment, laying before the jury credible evidence relevant to the alleged crime without notions of "winning or losing". Dawson J had emphasised that the Crown's function is to assist in the attainment of justice. Trial judges were expected to hold the balance without entering the arena (Ratten v The Queen). The proviso to s 668E(1) had been authoritatively construed in Weiss v The Queen as requiring the appellate court to make its own independent assessment of the admissible evidence and to be affirmatively satisfied that no substantial miscarriage had occurred; predictions about what a jury would have done were eschewed. Mraz v The Queen made clear that once an irregularity is shown the Crown bears the burden of negativing any real possibility that justice has miscarried. Directions on mistake of fact (s 24) and statutory defences required the real issues to be identified (Alford v Magee). The definition of intellectually impaired person in s 229F and the defence in s 216(4) had received little appellate elaboration.

After Libke the law is reinforced that inappropriate prosecutorial commentary during cross-examination, while deplored, will not automatically produce a miscarriage if the jury is not distracted from its proper task and the accused can still advance his case. Timely judicial intervention is expected but its absence is not fatal if, on the whole record, fairness is preserved. The distinction between cognitive capacity (s 348(1)) and the broader s 229F definition is confirmed; directions need only be tailored to the real issues thrown up by the evidence rather than abstractly reciting every statutory element. Belief under s 216(4) can rest on assumptions and does not require the accused to prove he turned his mind to a "real question" of impairment. The case illustrates that the Weiss assessment must focus on whether the appellate court can be satisfied no substantial miscarriage occurred, making due allowance for natural limitations on appellate review. The burden remains on the Crown once irregularity is established. The decision has not altered the statutory text but has clarified its practical operation in the context of robust cross-examination of an accused whose credit is central.

Key passages with plain-English translation

Gleeson CJ at [3]: "Most of the beliefs that form the basis of our dealings with other people are more in the nature of undisturbed assumptions than conclusions based on a process of reasoning."
Plain-English translation: Everyday beliefs about whether someone is normal are usually just gut feelings that nothing seems wrong, not careful logical deductions. Therefore Libke only needed to say she "seemed fine" to put the s 216(4) defence before the jury; the judge did not have to give complicated extra instructions.

Hayne J at [82]: "The comments the trial prosecutor made, in the course of cross-examining the appellant, departed from the rules that ensure the orderly conduct of a trial. But that observation does not answer the critical question presented by the appeal provision of the Criminal Code, which is said to be engaged. That question is whether there was a 'miscarriage of justice'."
Plain-English translation: Yes, the prosecutor broke the rules by giving his own opinions, but the legal test is not whether the prosecutor behaved badly; it is whether that bad behaviour actually stopped Libke from getting a fair trial under the statute. The court decided it did not.

Hayne J at [71]: "Would these repeated expressions of alignment with the prosecution case have distracted the jury from their task of assessing whether the evidence that was led at trial established the appellant's guilt beyond reasonable doubt? Would other aspects of the cross-examination have caused or contributed to that consequence? Both those questions should be answered 'no'."
Plain-English translation: Even though the prosecutor kept saying he did not believe Libke, the jury still focused on the evidence and decided count by count. The mixed verdicts prove they were not swept away by the prosecutor's attitude.

Kirby and Callinan JJ at [52]: "We are unable to accept that the 'very egregiousness of the conduct generated safeguards against the dangers inherent in it' or that the conduct of the prosecutor 'was such as to attract sympathy to the accused'. It is at least as likely that the jury... inferred that they reflected a justified hostility to the appellant which they were bound to share."
Plain-English translation: The dissenters rejected the idea that the prosecutor's rudeness was so obvious it would make the jury feel sorry for Libke. They thought the jury probably took their cue from the judge's silence and decided Libke was guilty because the prosecutor (a public official) clearly hated him.

Hayne J at [93]: "The trial judge told the jury that if they were to find that the complainant suffered from 'some intellectual deficit, that does not necessarily mean that that deficit will deprive the complainant of the cognitive capacity to give or withhold consent'. It follows from what has been said earlier in these reasons that this direction was correct."
Plain-English translation: Being intellectually impaired does not automatically mean a person cannot consent to sex. The judge was right to tell the jury to look at whether she actually agreed freely, not just at her IQ score.

What fact patterns trigger this precedent

This precedent is triggered where an accused is tried for sexual offences against a person who meets the s 229F definition of intellectually impaired person, the accused gives evidence that the complainant "seemed fine", "was confident" or appeared normal in conversation and demeanour, and the prosecution case relies substantially on the complainant's s 93A video-recorded evidence together with the accused's own testimony. It applies when the prosecutor, during cross-examination of the accused, makes repeated sarcastic comments, expresses personal disbelief ("I'm not buying it"), characterises the evidence as lies, uses compound or argumentative questions, cuts off answers, or rests questions on unproved assumptions, and the trial judge does not intervene. The case is engaged on appeal where the accused argues miscarriage of justice under s 668E(1) on the basis of unfair cross-examination and/or inadequate directions on cognitive capacity (s 348(1)), the distinction from intellectual impairment (s 229F), or the s 216(4) defence of reasonable belief. It is particularly relevant where the jury returns mixed verdicts, trial counsel makes no objection or request for redirection, and the appellate court must apply Weiss to determine whether it can be affirmatively satisfied that the irregularity could not reasonably have influenced the result. The precedent operates in any jurisdiction applying the Queensland Criminal Code where credit is central and the accused's belief about the complainant's capacity rests on assumption rather than explicit inquiry. It does not apply where the cross-examination remains within ordinary vigorous bounds or the judge gives a clear early warning in the jury's absence.

How later courts have treated it

The judgment itself shows how the High Court treated the authorities it cited. Whitehorn v The Queen was applied to restate the prosecutor's duty to act fairly without personal alignment (Hayne J at [54]-[56]; Kirby and Callinan JJ at [30]-[32]). The court followed rather than distinguished Whitehorn, using it to measure the prosecutor's comments against settled standards while emphasising that breach does not automatically equal miscarriage. Weiss v The Queen was applied at length (Hayne J at [92]-[101]; Kirby and Callinan JJ at [70]-[80]) to reject any test based on "inevitable conviction" or hypothetical jury predictions; the majority used Weiss to perform its own assessment of the record and conclude no substantial miscarriage had occurred, while the minority used the same case to hold that significant denial of procedural fairness prevented affirmative satisfaction that no miscarriage had occurred. Mraz v The Queen was cited for the proposition that once irregularity is shown the Crown must satisfy the appellate court there is no real possibility justice has miscarried (Kirby and Callinan JJ at [75]). The Court of Appeal decision in R v Libke [2006] QCA 242 was affirmed on the conviction appeal (Hayne J at [25]) with the High Court endorsing Mullins J's assessment that the matter was one of degree and that the appellant had been able to handle the cross-examination. Heydon J's separate remarks on the rules of evidence (offensive questioning, comments, compound questions, cutting off answers, argumentative questions) were presented as orthodox and drawn from earlier common-law authorities such as Mechanical and General Inventions Co Ltd v Austin and R v Baldwin; the court treated those rules as breached but not ultimately productive of unfairness on the whole record. No member of the court overruled any prior authority; the split illustrates that application of the proviso and assessment of "degree" in prosecutorial misconduct remain fact-sensitive.

Still-open questions

Several questions remain unresolved after this decision. First, the precise threshold at which repeated prosecutorial comments shift from "regrettable" to productive of a miscarriage, particularly where the trial judge remains silent, is left as a matter of degree; the 3:2 split demonstrates that reasonable minds can differ on whether the jury would take judicial non-intervention as endorsement of hostility. Second, the extent to which an appellate court may rely on mixed jury verdicts as evidence that the jury was not distracted remains open; the majority treated the verdicts as powerful, yet the minority viewed them as equally consistent with prejudice. Third, the circumstances in which further elaboration of the s 216(4) defence is required, beyond simply leaving the statutory question where the accused says the complainant "seemed fine", are not exhaustively stated; Gleeson CJ's observation about undisturbed assumptions is powerful but its application where the complainant exhibits more obvious signs of impairment is untested in the reasons. Fourth, the interaction between s 21 of the Evidence Act 1977 (Q) (improper questions) and the trial judge's common-law duty to intervene is acknowledged but the judgment does not prescribe when intervention must occur in the presence of the jury versus in its absence. Fifth, the weight to be given to defence counsel's failure to object or seek redirection is confirmed as relevant but not decisive; the limits of that relevance where the cross-examination is "wild, uncontrolled and offensive" (Heydon J at [118]) are not finally settled. Finally, whether a s 216(4) belief must be "subjective" in any technical sense or can always rest on absence of contrary indication remains open for cases where the evidence is more equivocal than Libke's. These open questions mean that trial judges and prosecutors must still exercise fine judgment in real time, and appellate courts will continue to examine the whole record rather than apply bright-line rules.

GLEESON CJ. I have had the advantage of reading, in draft form, the reasons for judgment of Hayne J. I agree, for the reasons given by Hayne J, that the appeal should be dismissed. I would add two brief observations.
First, the argument that the conduct of the prosecutor during his cross-examination of the appellant resulted in an unfair trial, and a miscarriage of justice, involved a question of degree. As Mullins J pointed out in the Court of Appeal, the cross-examination of the appellant extended over 44 pages of transcript. In the course of that cross-examination, counsel made certain inappropriate comments. It is difficult for an appellate court, relying only on the written record, to assess the impact of undisciplined conduct by counsel. It is also difficult, away from the atmosphere of the trial, to measure the significance of the absence of intervention by the trial judge or by opposing counsel. Those difficulties are to be taken into account by way of caution in approaching any attempt to minimise the complaints made on behalf of the appellant. Even so, having read the whole of the evidence of the appellant, I would not interfere with the Court of Appeal's conclusions that the conduct of the prosecutor did not make the trial unfair.
Secondly, I agree that, in the circumstances of this case, in order to raise for the jury's consideration the defence provided by s 216(4) of the Criminal Code (Q), it was not necessary for the appellant to go beyond saying that the complainant "seemed fine". The appellant did not have to show that he thought there was a real question about the complainant's intellectual capacity, and arrived at an answer to that question. Most of the beliefs that form the basis of our dealings with other people are more in the nature of undisturbed assumptions than conclusions based on a process of reasoning. It was for the members of the jury to decide, in the light of all the material before them, including their assessment of the appellant, and their observation of the complainant, whether the appellant's evidence that the complainant "seemed fine" established a belief by the appellant that the complainant was not intellectually impaired, and whether that belief was on reasonable grounds. The case was left to the jury on the basis that it was open to decide those issues favourably to the appellant on the basis of that limited evidence. It was not necessary, and it would probably not have been to the appellant's advantage, for the trial judge to give more elaborate directions on the point. It is not surprising that trial counsel did not seek further directions.

Mr Justin Libke (the appellant) was found guilty by a jury, and convicted, after a trial in the District Court of Queensland (Griffin DCJ) on one count of rape, two counts of unlawful carnal knowledge of an intellectually impaired person, one count of unlawful exposure of an intellectually impaired person to an indecent act, and of unlawful and indecent dealing with an intellectually impaired person. The verdicts on counts 2, 3 and 4 were lesser and alternate verdicts. The indictment alleged three counts of rape, one count of indecent dealing with an intellectually impaired person, and one count of sodomy of an intellectually impaired person.
The complainant was 18 years old at the time of the events with which the Court is concerned. She is intellectually impaired. There was little or no contest about that at trial. Issue was joined, however, on the degree of impairment, and the extent to which impairment was apparent in her appearance, demeanour, speech and conduct generally.
The appellant was 39 years old. He met the complainant at a park where they exercised their dogs. After they introduced themselves, the appellant asked the complainant how old she was. She told him that she was 18. The appellant described her as being of Asian appearance, and speaking with an "Asian-type accent", with a lisp. She seemed "fine", he was later to say in evidence, "in regards to her mental health".
They met again at the park about two weeks later. The complainant told the appellant that her mother had been born in Malaysia and that her father was from England. The complainant neither said nor implied that she was in any way intellectually impaired. Nor did she mention that she had undertaken a special education course, or that she was unable to live unsupported.
It was common ground that, on their second meeting at the park, when they were seated on a bench, the appellant touched the complainant's legs, put his hand in her shorts and his finger in her vagina. She agreed that she did not say "no". That was the subject of count one. The complainant accepted in cross-examination that when the appellant asked her in the park, "Do you want to fool around a little?", she said "Yes", but that she did not know what that meant. In a videotaped record of interview, the complainant was asked "What if somebody came along?" She responded that that was what the appellant was checking for, adding:

"… I asked him at first like what he was doing and I kind of . . . I refused to let him do it. He goes, 'Why?' and I didn't answer him at first because I don't know why [indistinct]. I just didn't answer him because I [indistinct] know him. I don't know why [indistinct], yeah."

The complainant was asked where her hands were when the appellant was touching her and she said they were by her side. She confirmed during cross-examination that she did not tell the appellant to stop or take his hands away. But when it was put to her that she responded or acted, as the appellant was touching her, as though she liked what the appellant was doing, she said "No".
As to the circumstances surrounding this, the first charge, of digital rape, there was a dispute as to the implied invitation said to have been offered by the complainant to the appellant. Williams JA in the Court of Appeal took the view that the appellant's evidence departed from the matters put in cross-examination of the complainant. His Honour said[2]:

"Counsel for the appellant in addressing this Court placed great emphasis on a passage in the cross-examination of the complainant as to her conduct immediately after the appellant touched her on the vagina with his finger; the critical questions and answers are as follows:

'And when he did that, put his fingers down your trousers to touch your vagina, you turned to face him, didn't you? - Yes.

And you did that to allow him to touch your vagina more easily. Do you understand? You were doing that to enable him to touch you on the vagina. You tell me if you don't understand? - I understand.

What I am suggesting is you turned your legs towards him and opened them slightly so it would make it easier for him to get his fingers to your vagina. That's what happened? - Yes.'

That passage in the evidence was emphasised by defence counsel in his address, and was also referred to in the summing up. It clearly was of critical importance to the jury's deliberations. It is significant that at that point in cross-examination counsel was apparently putting to the complainant the defence case; after the appellant touched her vagina she parted her legs to give him easier access. Though the complainant said that she understood what was being put to her, it was still a question for the jury as to the reliability of her responses to what was being put to her, and what weight, if any, should be attached to the adoption of what was put to her when considered in the light of all the evidence given at trial.

That passage in the evidence of the complainant was the focus of attention during addresses and summing up also because in his evidence the appellant told a different story. His evidence was not that after he initially touched the complainant's vagina she opened her legs to make access easier, a scenario which might suggest cognitive consent on her part. Rather his evidence was to the following effect. Whilst they were sitting on the park bench and he was rubbing her legs, she 'swung her legs towards' the appellant, and when she did so 'I seen her pussy'. According to the appellant's evidence-in-chief: 'I just seen it, and then I just put my finger [in] her vagina.' Nothing of the sort had been put to the complainant in cross-examination, and she had not been asked any questions about the nature of the underwear she had on at the time. Under cross-examination by the Crown prosecutor the appellant said that the complainant's underwear was 'loose'; she had loose shorts and loose underwear. On that account the complainant either deliberately or accidentally displayed her vagina to the appellant and he immediately inserted his finger.

Given the complainant's intellectual capacity and her obvious difficulty in understanding a number of things put to her in evidence, and given the propositions put to her in cross-examination which she apparently adopted, and given that those matters were not then confirmed by the appellant in his evidence but he gave a contrary version which was not put to the complainant, the jury may well have considered that the complainant's apparent adoption of the proposition that she opened her legs to give easier access to her vagina was deserving of little, or no, weight. As already noted it was for the jury in all the circumstances of the case to determine the significance to be attached to the adoption of the proposition put to her."

We observe at this stage that, although we would not ourselves attach to the departure between the matters put and not put on behalf of the appellant, and the evidence that he subsequently gave, the same significance as his Honour did, we do agree that it was for the jury to evaluate the complainant's evidence as a whole on the issue of her actually consenting, or appearing to do so.
All of the events the subject of the other charges occurred on the one occasion. We adopt the summary of it given by Mullins J in the Court of Appeal. Her Honour said[3]:

"A couple of days later on 9 October 2002 the appellant telephoned the complainant at home and asked her if she wanted him to come over and she said that she did. The complainant let the appellant into the house. There was no one else at home. The appellant told the complainant that he could not stay for long. He asked her 'Do you want to have sex?' and the appellant gave evidence that the complainant responded affirmatively, but the complainant said that she did not say anything. The appellant asked her again whether she was 18 years old and she said she was. They went into the lounge room. The appellant undressed. The complainant then undressed. The complainant closed the blinds. The appellant gave evidence that at the park the complainant had told him when he came over to bring protection. In cross-examination the complainant said that she did not say anything like that. The complainant said that when the appellant was undressed she asked him if he had a condom and that he said 'Yes'. The appellant had brought a condom with him and he put it on.

The complainant stated in her record of interview that they lay down on the lounge room floor and the appellant got on top of her and '… he kissed me and then he started, um, putting his penis in me' and described what happened:

'And do you think it went in - into your - into your body very far? -- Yeah, it went pretty far because it started hurting.

Did it? -- Yeah. And then he took - and I told him in the middle of it, and then when I told him, he took it out, and then, um, after that he, um - before I told him it hurt it, like, um - no, when - after I told him it hurt, he said that he needed a wank, and then - that's when he first went in with his fingers and then he had something on this - um, on the condom as well.'

This sexual intercourse was the subject of count 2.

The complainant described seeing the appellant have 'a wank'. This was the subject of count 3. The complainant said that the appellant tried to put his penis back in her vagina again, but '… he didn't put it too far in because I told him it hurt'. The complainant said that the appellant then turned her around so that she was on her knees and '… then he, um, stuck his penis in my arse after that, yeah, but it didn't hurt because he didn't stick it far' and that she 'didn't feel it'. This was the subject of count 5. In cross-examination the complainant agreed with the suggestion that when she was on her knees, the appellant was moving his penis in the area of her vagina. The complainant also agreed in cross-examination that they both then lay beside each other on the floor, the appellant felt her vagina with his finger and that he tried again to have intercourse with her. This was the subject of count 4.

In cross-examination the complainant accepted that at the committal hearing she had agreed that she was attracted to the appellant in a sexual way and she agreed that she had said at the committal that the whole reason that she had wanted the appellant to come over to her house was because she knew that there would be sexual activity and that she had sexual feelings, urges and desires.

The appellant said in evidence-in-chief that when they lay down on the lounge room floor, he lay on top of the complainant, but could not keep an erection. He said that he tried to stimulate himself whilst sitting up a bit and that they changed positions in that the complainant got on her knees and he attempted to insert his penis into her vagina from behind her. He said he was unsuccessful in doing that and denied putting his penis into the complainant's anus. The appellant said that they lay on the carpet again and that his penis entered the complainant's vagina 'a little way'.

Both the complainant and the appellant got dressed and the complainant let the appellant out. The complainant stated that before the appellant left, he told her 'not to tell anybody at all'. The appellant stated that he did not make any such statement to the complainant."

Almost the entirety of the complainant's evidence-in-chief consisted of video tapes of interviews of her made and tendered pursuant to s 93A of the Evidence Act 1977 (Q) (the "Evidence Act"). That section relevantly provides as follows:

"93A Statement made before proceeding by child or intellectually impaired person

(1) In any proceeding where direct oral evidence of a fact would be admissible, any statement tending to establish that fact, contained in a document, shall, subject to this part, be admissible as evidence of that fact if -

(a) the maker of the statement was a child or an intellectually impaired person at the time of making the statement and had personal knowledge of the matters dealt with by the statement; and

(b) the maker of the statement is available to give evidence in the proceeding.

(2) If a statement mentioned in subsection (1) (the main statement) is admissible, a related statement is also admissible as evidence if the maker of the related statement is available to give evidence in the proceeding.

(a) made by someone to the maker of the main statement, in response to which the main statement was made; and

(b) contained in the document containing the main statement.

(3) Where the statement of a person is admitted as evidence in any proceeding pursuant to subsection (1) or (2), the party tendering the statement shall, if required to do so by any other party to the proceeding, call as a witness the person whose statement is so admitted and the person who recorded the statement."

No point was sought to be taken by the complainant with respect to the conduct of the interviews, and the repetitive nature of some of the questions asked, in consequence of which the complainant may have been given the opportunity of rehearsing her evidence, and causing it to be reinforced in the minds of the jury as they watched and listened to the video tape.
The complainant was cross-examined at some length about her conversations with the appellant:

"You never told Justin what school you attended? -- No, I didn't.

You never told him what your results were at school? -- No, we didn't talk much about anything.

Alright. Well, I have to ask you these questions? -- Yeah, I know.

You didn't tell him that you were doing a special educational course, did you? -- No, I didn't.

You didn't tell him what subjects you were doing? -- No.

You didn't tell him that you had any difficulties or disabilities, did you? -- No, I didn't.

You could fully understand - apart from those words you said you didn't know what playing around meant, you could fully understand everything else he was saying to you? -- Yes.

And you responded to what he was saying to you? You answered . . . ? -- Yes.

. . . his questions or had a conversation with him? -- Yes.

Was there anything else you remember him saying that you didn't understand? -- No, I don't.

You didn't tell him, for instance, that you'd only done unpaid work experience? -- No.

You didn't, or he didn't get you to count any money or anything like that? -- No.

He didn't go shopping with you at any stage, did he? -- No.

You didn't tell him you couldn't work a cash register or anything like that? -- No.

You never told him that you have trouble travelling on a bus or train by yourself? -- No.

And you had no difficulty in understanding - apart from that mucking around, the playing around - you didn't understand that - you had no difficulty in understanding what he was talking about? -- What do you mean?

Well, you were able to converse with him? -- Converse - what do you mean converse?

Talk, talk back and forwards? -- Yeah, we were just -

… you had no difficulty in understanding what he was saying apart from that playing around, whatever you said, alright? -- Yeah.

And did he appear to have any difficulty in understanding what you were saying? -- I don't think so."

The complainant agreed that she had opened her legs slightly to make it easier for the appellant to insert his fingers into her vagina when they met in the park for the second time. She also agreed that she had given evidence at the committal hearing that the whole reason that she wanted the appellant to come over to her house was because she knew that there would be sexual activity, and that she did have sexual urges and desires.

The appellant gave evidence at the trial. He was subjected to a scornful cross-examination punctuated by interruptions of answers and comments, but not, regrettably, objection by counsel or intervention by the trial judge.
To understand how the cross-examination may have affected the outcome of the trial, a deal of it needs to be set out:

"Well, you have heard her say you parked your car down the road? -- Yeah.

Did you tell her you parked your car down the road? -- No, she said when she was closing the blinds - she goes, 'Where's your car?'

This was when you and she were in the heat of passion, was it? -- No.

She asked where your car was? -- No, no, when she was closing the blinds, the . . .

Well, this is when you were undressing . . . ? -- Yes, yeah.

. . . in the course of your passions. She asked where your car was? -- Yeah, no, when she was closing the blinds she looked out the window and she says, 'Where's the car?', and I said, 'It's down the road.'

Why didn't you say it was just next door? -- I just said, 'It's down the road.' I didn't - it wasn't - it wasn't an issue.

Yes, it is. I put it to you your car was in fact parked down the road because you wanted to keep as discreet as you could your presence at her house? -- Well, I was parked next door."

The prosecutor questioned the appellant about his motives for telephoning the complainant from outside her house on the day of his visit to it:

"But she answered the phone the second time, didn't she? -- Yeah.

If you had been ringing to see whether she was the only occupant there that would have been a fair indication she was the only one home, wouldn't it? -- No, the music was up loud.

Oh, yes. Look, I've heard all of that. I'm trying to convey to you I'm not buying it. I suggest you rang the second time just to check the coast and just see if, perhaps, you know, one of the other family might have been there and answered the phone? -- No, not at all. Not at all."

On the topic of the first encounter in the park, the cross-examination included the following:

"How long were you with her on that occasion? -- On the first time down the park?

Yeah? -- Oh, maybe - how long was I talking to her or how long was I in the park? I can't . . .

I asked you how long you were with her? -- On the first occasion? I never - well, it could have been half an hour.

Well, you're the person who's the historian. How long was it? -- I don't know if …

. . . you just celebrated your 39th birthday, the first day of it. As a grownup man, you're telling us it was half an hour? -- Half an hour. I don't know. I don't know exactly how long it is. So I can't say - it could have been around half an hour.

I didn't ask you how . . . ? -- No, I can't say then it was half an hour. I can't establish exact time.

Not the exact time if you're saying it was about half an hour, that means it may have been 25, it might have been 35 minutes? -- It could have been.

At least, anyway, in the vicinity of half an hour, right? -- It could have been.

We can only stand upon you for this, you see. I don't recollect she was asked how long you were together? -- Pardon?

Sorry, that may be a comment. I apologise for that. On your adult assessment, you were together for about half an hour? -- Yeah."

The prosecutor interrupted the appellant when he was trying to respond to further questions about the complainant's and the appellant's first meeting:

"Describe and tell to the jury what the circumstances were of your first encounter face-to-face with this young woman? -- We were in the park and I . . .

That doesn't tell us much, does it? -- I'm not quite sure what you're trying to say.

I'm not trying to say a thing. I'm trying to get you to say something? -- I know."

The prosecutor resumed asking questions about that occasion:

"She talked to you first, did she? -- I can't remember. I can't remember if I introduced myself to her first or she introduced herself to me first.

'Introduced', that means giving names, does it? -- No, just saying 'Hello'. I can't remember if I introduced myself to her and she introduced herself to me.

Look, I'm giving you every opportunity? -- Honestly, I can't remember.

I'll shift to another topic whenever you're prepared to finish it. Is that what you're prepared to tell us, you don't know how the two of you first became acquainted? -- I thought - the way we became acquainted was in the park.

When you first became of her - aware of her existence as a human being within the Brisbane area? -- I just don't understand what - what - I honestly. Sorry, your Honour, I just - if you could explain. I'm not quite sure if I'm explaining myself right, or anything like that. But I don't know if I started the conversation first or she started it or I approached her or she approached me. I just can't remember that, I'm sorry.

Now, that's the appearance. The accent. How long did it take you to appreciate she had an Asian accent? -- I worked with Asians at that stage, so it didn't bother me if she had an Asian accent or not.

It doesn't bother anybody in this courtroom either, but how long did it take you to appreciate that she had as well as an appearance but also an Asian accent? -- How long did it take me to realise it?

First couple of minutes? -- I can't recall. I really can't recall or . . .

During? -- I'll be saying something which I - I don't know that I thought of at the time.

We want honesty at all times, of course. So, during the course of that half hour, you don't know what stage, but well and truly within the half hour, you appreciated not only did she have an Asian appearance but she had an Asian accent; is that right? Is that right? -- Well, you're putting the question to me and . . .

I am? -- I'm not quite sure of - of what the - what you're . . .

HIS HONOUR: Don't, Mr Libke, worry at all about where [the prosecutor] is going, if he is going anywhere with the question. Just answer the questions to the best of your ability. -- Can you put the question to me again please?

[THE PROSECUTOR]: Yes. During the course of around about half an hour interlude with her on that first occasion, you say very very shortly after seeing her, meeting with her, you realise she was of Asian appearance? -- Yes.

During the course of that around about half an hour, how long did it take you to realise she had an Asian accent? -- I don't know if I - I don't know if it took - I don't know what time it took, sorry, I don't know.

No, don't talk about knowing. I asked you did it ever appear to you or occur to you she was retarded? -- No.

You have used the word 'no'. I'm trying to concentrate on the 'appear' to you to be? -- Appeared to me.

Anyway, as you say, she was very competent. You said the word two or three times she was very competent. What did you mean by that? -- She seemed confident.

I didn't get the right word. Was it competent or confident? What word did you use? C-O-N-F-I-D-E-N-T; was that the word? -- Confident.

Was that the word you used? -- Confident as in confident.

She was very confident. Well, what gave you the impression she was so confident? -- Because she - she -well, I'm just trying to think. She's just a confident person.

I see? -- Because she approached me, she chats and . . .

Did she run off at the mouth? -- Run off at the mouth?

As you saw her on the video did she run off the mouth? -- How do you mean?

As per the video that you saw did she run off the mouth like that when she was chitchatting with you? -- No.

No? Her conversation was very chitchat and controlled, was it? -- Yes.

Nothing unusual about it? -- Apart from her accent.

Apart from the accent? -- Which I asked her about later on and she said - and . . .

Apart from the accent was there anything unusual about her chitchat? -- I don't know what to say …

Could you just answer was there anything unusual about her conversation, manner of speaking? -- It was, she had a bit of an accent.

The accent was the only thing that . . . ? -- Well, I'd been working with Chinese and they had a thick accent.

Yes. Did she have a thick Chinese accent, did she? -- It was similar to the people who were running the Cisco's Cantina at that time. I'm not saying the same but it was similar.

Did you have any trouble understanding this girl? -- Some things, yeah.

So you weren't able to sort of zero in on what her address was? -- Yeah, I remember that.

I put it to you of course that none of this happened, but anyway I'm just trying to analyse your version of it? -- Well, none of what happened?

She turned - I put it to you your evidence is just a tissue of lies. That's what I'm putting to you, and I'm trying to work out just what it is that you're trying to tell us. She turned towards you? -- Mmm.

I put it to you in short that you took advantage of this girl, you importuned her, knowing full well she was disabled, that's what I put to you? -- No sir.

Now, you told her how you quit your job? -- I told her how I quit it.

Now we've heard with great rhapsody this morning about how and why you quit your job, but did you tell her that you quit it because you weren't being paid enough? -- Oh, that was one of the reasons. (emphasis added)

You heard her asked, 'What stuff were you talking about?' She answered, 'I don't know, just talking about movies, or something, and so was he' and then something indistinct, 'he wasn't interested anymore'? -- I can't remember talking about movies and DVDs.

You're good changing the subject of the girl when you're talking with her in the park? -- Changing . . .

Changing the subject. In other words, away from movies, that sort of thing, changing the subject to something else? -- No.

The appellant put the complainant's telephone number into his mobile telephone under the first three letters of her name. He was cross-examined about his "dishonesty" in doing so:

"Your counsel opened the case to the jury by saying you were trying to cut off any inquiry your wife - your de facto might have made about it? -- Yeah.

Is that why you did that? -- Yeah, that's another reason too.

Well, another piece of cunning, deception if your de facto happened to have a look at your phone? -- Oh, yeah, I guess so, I . . .

How long had you and the de facto been together for? -- Oh, about three years.

About three years. Did your de facto situation with her occur to you as you were ringing from the freeway, or on the morning that you went to - with a condom in your pocket? -- Did it occur to me?

Alternatively, I put it to you that, in any event, you knew and had every reason and, in fact, did know, that she was of much less than normal intellect? -- I didn't know she was intellectually impaired.

In other words, I put it to you that you knew that she was an intellectually impaired person? -- How do I know she is an intellectually impaired person?

HIS HONOUR: No. I don't think I said to you before, Mr Libke, you can't ask questions. It's [counsel's] role … You're simply there to answer them.

[THE PROSECUTOR]: I put it to you you had every reason to believe, to understand, to apprehend, to comprehend, to realise that she was an intellectually impaired person? -- No.

I put it to you, further, you had every reason to understand, to believe, in fact, you did believe and you knew that and had every reason to know she was an intellectually impaired person when you had those dealings with her in the house? -- No.

And the bottom line … is that you knew that girl was the victim of intellectual impairment? -- I didn't know that.

And there was not the slightest indication to you that she was intellectually impaired; is that what you're saying, by word, thought, gesture? -- Intellectually impaired, no.

I'll go through it again. By way of her words, there was nothing to indicate to you she was intellectually impaired? -- I got the impression she had a lisp, or something like that.

We've heard about that one? -- Well, that's the truth."

The appellant was cross-examined on the basis that his evidence of talking to the complainant about moisturiser was an invention:

"Why would you have to be telling her, asking her about the rash on her leg and talking about moisturiser to her? -- I just suggested that it might need some moisturiser.

See, I put to you that's just another one of these inventions of yours to try to cover every nook and cranny of the case against you. In other words, the rash on the legs, moisturiser, advice, therefore, that gives you a basis, you know, for explaining about how we came to be talking about legs? -- No. No, I didn't even think of it like that. I was just telling her - I don't know, that she had dried legs."

The prosecutor was wrong to characterize the appellant's evidence about the moisturiser as an invention in light of the complainant's evidence to the same effect.
The prosecutor then put what he described as a "general proposition" to the appellant. This exchange occurred:

"In other words - anyway, I'm putting to you wherever you see a situation there that's a problem you will thrash around to try to make up some explanation for it, whether it's a van, whether it's next door, whether it's rashes, whether it's moisturiser, whatever. Whatever. Do you want to comment? -- No, you're commenting to me.

After the appellant was found guilty by the jury, as described at the outset of these reasons, the trial judge convicted him and sentenced him to eight years' imprisonment.

The appellant unsuccessfully appealed against his convictions to the Court of Appeal of Queensland (Williams JA and Mullins J, Chesterman J dissenting on the conviction for rape). The sentence was unanimously reduced to five years' imprisonment.
Before the Court of Appeal, the appellant did not present a specific ground of appeal relating to the conduct of the prosecutor. However, as his grounds of appeal were prepared without access to the record, he reserved his right to amend the grounds. Whether on this basis, or as relevant to other grounds of appeal, there is no doubt that, on the hearing of the appeal, the appellant complained "that he was not fairly treated by the prosecutor when he was cross-examined"[4]. An extensive portion of the reasons of Mullins J addressed that complaint.
Her Honour records the prosecution submission that "in the context of the whole of the evidence given at the trial, the approach of the prosecutor did not cause the appellant to be unfairly treated"[5]. She also records the reliance of the prosecution, on the appeal, upon the "minimal intervention by the trial judge as indicative of how the cross-examination of the prosecutor was perceived at the trial". Her Honour observed that "the credit of the appellant was clearly in issue at the trial" and that "a vigorous cross-examination of the appellant was to be expected". Whilst deprecating "gratuitous comments" she stated that it was "a question of degree whether the number and content of such comments have prejudiced a fair trial". She concluded that the appellant had been "able to handle the cross-examination" and she was influenced by the lack of objection from the appellant's trial counsel[6].
The complaint about the prosecutor's conduct was described as involving few successful points and these were judged insufficient to warrant the intervention of an appellate court. Other members of the Court of Appeal, in their reasons, did not deal separately with this issue. By inference they concurred in Mullins J's analysis and conclusions on this point. In our view, and with respect to their Honours, this amounted to error.

The appellant argued in this Court that a miscarriage of justice occurred by reason of the prosecutor's cross-examination of him, and commentary during it.
The principles governing the conduct of a prosecutor are well settled. They were restated by Deane J in Whitehorn v The Queen[7]:

"Prosecuting counsel in a criminal trial represents the State. The accused, the court and the community are entitled to expect that, in performing his function of presenting the case against an accused, he will act with fairness and detachment and always with the objectives of establishing the whole truth in accordance with the procedures and standards which the law requires to be observed and of helping to ensure that the accused's trial is a fair one. The consequence of a failure to observe the standards of fairness to be expected of the Crown may be insignificant in the context of an overall trial. Where that is so, departure from those standards, however regrettable, will not warrant the interference of an appellate court with a conviction. On occasion however, the consequences of such a failure may so affect or permeate a trial as to warrant the conclusion that the accused has actually been denied his fundamental right to a fair trial. As a general proposition, that will, of itself, mean that there has been a serious miscarriage of justice with the consequence that any conviction of the accused should be quashed and, where appropriate, a new trial ordered."

"No doubt all of these observations are merely aspects of the general obligation which is imposed upon a Crown Prosecutor to act fairly in the discharge of the function which he performs in a criminal trial. That function is ultimately to assist in the attainment of justice between the Crown and the accused. In this respect the Crown Prosecutor may have added responsibilities in comparison with other counsel but it does not mean that his is a detached or disinterested role in the trial process."

The role of prosecuting counsel is not to be passive. He or she may be robust, and be expected and required to conduct the prosecution conscientiously and firmly. Because a criminal trial is an adversarial proceeding, there is at least the same expectation of defence counsel. The obligation of counsel extends to the making of timely objections to impermissible or unacceptable questions and conduct. But it is also the duty of the trial judge to make appropriate interventions if questions of those kinds, capable of jeopardizing a fair trial, are asked. The duty of the trial judge is the highest duty of all. It is a transcendent duty to ensure a fair trial.
Section 21 of the Evidence Act, which provides as follows, does not suggest that a trial judge, even in an adversarial system, may not or should not intervene:

(1) The court may disallow a question put to a witness in cross-examination or inform a witness a question need not be answered, if the court considers the question is an improper question.

(2) In deciding whether a question is an improper question, the court must take into account -

(a) any mental, intellectual or physical impairment the witness has or appears to have; and

(b) any other matter about the witness the court considers relevant, including, for example, age, education, level of understanding, cultural background or relationship to any party to the proceeding.

(3) Subsection (2) does not limit the matters the court may take into account in deciding whether a question is an improper question.

improper question means a question that uses inappropriate language or is misleading, confusing, annoying, harassing, intimidating, offensive, oppressive or repetitive."

In this case we are unable to conclude that the appellant did have a fair trial. Whether a cross-examination and commentary during it were excessive will usually be a question of degree. It would not be appropriate to require a standard of perfection or to impose undue weight on the occasional accidental slips and mistakes that can occur in the heat of a trial. Further, it is true that the appellant's credit was in issue and a rigorous cross-examination was therefore to be expected. However, it was seriously objectionable for a counsel to say, during an address to the jury, that he or she "did not buy" something said by a party in evidence, or that "we've heard about that one". It is not acceptable for counsel to make that comment, that is, to express a personal opinion about a party's, or indeed any witness', evidence during cross-examination as the prosecutor did here. It was equally inappropriate for counsel to comment after the appellant had made a responsive answer "whenever you're prepared to finish it". In the same category are these comments: "That doesn't tell us much, does it?"; "I'm just trying to analyse your version of it" and, "hopeless" in commentary upon an answer. These are but a few examples of the inappropriateness of the cross-examination. Here, the sarcastic and repeated commentary as a whole went too far. The appellant's counsel's failure generally to object, regrettable as that may have been, provided no antidote to the infection of the trial that the prosecutor's questions and comments caused. The circumstances called for the trial judge to intervene.
In his reasons Heydon J too has demonstrated the entirely unsatisfactory nature of the conduct of the trial of the appellant involved in the approach taken both by the prosecutor[9] and the trial judge[10] during cross-examination. In effect, they complement our own. Merely to offer judicial disapprobation to discourage[11] unsatisfactory prosecutorial conduct of this kind in the future can be of no solace to an accused the subject of it.
We are unable to accept that the "very egregiousness of the conduct generated safeguards against the dangers inherent in it" or that the conduct of the prosecutor "was such as to attract sympathy to the accused"[12]. It is at least as likely that the jury, considering the way the prosecutor as a public official, and the judge as the controller of the trial acted, took their cue from the improper questions and comments, and apparent judicial acquiescence in them respectively, and inferred that they reflected a justified hostility to the appellant which they were bound to share. Clearly their verdict is more consistent with that reaction than with any sympathy.

Every member of the Court accepts at least that the prosecutor's comments were inappropriate and should not have been made[13], and that in making them he aligned himself personally with the prosecution case. Nor does any judge question that, even though the proceedings were adversarial, the trial judge could have intervened to check the persistently inappropriate commentary of the prosecutor.
Weiss v The Queen[14] does not stand in the way of allowing the appeal; indeed to the contrary. The principal issue in Weiss was whether the intermediate appellate court was right to apply the proviso in an appeal against conviction on the grounds of the wrongful reception of irrelevant prejudicial evidence. The appeal by the accused to this Court was upheld, essentially because the Court of Appeal had allowed itself to be deflected by the formulation of a question whether the test to be applied was whether the jury in whose charge the appellant had been put would inevitably have convicted him, or whether any notional reasonable jury would have done so, instead of applying the statutory language of the proviso. As always, the remarks of this Court in its reasons have to be read and understood in the context of the precise issue presented for its decision there.
In Weiss, after reviewing the history of the statutory demise of the Exchequer rule in criminal cases and pointing out that in consequence, an appellate court was not obliged in all cases in which irregularities had occurred to uphold an appeal, the Court said this[15]:

"Likewise, no single universally applicable criterion can be formulated which identifies cases in which it would be proper for an appellate court not to dismiss the appeal, even though persuaded that the evidence properly admitted at trial proved, beyond reasonable doubt, the accused's guilt. What can be said, however, is that there may be cases where it would be proper to allow the appeal and order a new trial, even though the appellate court was persuaded to the requisite degree of the appellant's guilt. Cases where there has been a significant denial of procedural fairness at trial may provide examples of cases of that kind."

The foregoing statement must be read with the several others[16] made in this Court which emphasise that, once it is shown, as it has been to all members of this Court, that irregularities disadvantageous to the appellant occurred at his trial, it is for the prosecution to satisfy the appellate court that such irregularities have caused no substantial miscarriage of justice. This is clear from the oft cited passage of Fullagar J in Mraz v The Queen[17]:

"It is very well established that the proviso to s 6(1) does not mean that a convicted person, on an appeal under the Act, must show that he ought not to have been convicted of anything. It ought to be read, and it has in fact always been read, in the light of the long tradition of the English criminal law that every accused person is entitled to a trial in which the relevant law is correctly explained to the jury and the rules of procedure and evidence are strictly followed. If there is any failure in any of these respects, and the appellant may thereby have lost a chance which was fairly open to him of being acquitted, there is, in the eye of the law, a miscarriage of justice. Justice has miscarried in such cases, because the appellant has not had what the law says that he shall have, and justice is justice according to law. It is for the Crown to make it clear that there is no real possibility that justice has miscarried."

As it is put in Stokes v The Queen[18], an appellate court should only apply the proviso if the irregularity "could not reasonably be supposed to have influenced the result". If this cannot be ruled out, it may be impossible for a court to be satisfied that a substantial miscarriage of justice has not occurred. What occurred here could not justify the negative supposition required to deny the appellant a retrial. In our view this is so even if the irregularities were confined to the prosecutor's comments and did not extend, as we believe, to the questions that we have identified.
Not only will there be cases in which it is proper to allow the appeal and order a new trial, even though the appellate court may be persuaded on the admissible evidence to the requisite degree of the appellant's guilt, but also, as much more often will be the case, even after a careful examination of the record for itself, it will simply be impossible for that court to assess the impact of the irregularities on the fairness of the trial. Ultimately, an appellate court may only apply the proviso if it is affirmatively satisfied that no substantial miscarriage of justice to the accused has occurred[19]. A significant denial of procedural fairness will not, of course, be the only occasion for allowing an appeal. The reasoning of the Court in Weiss does not suggest otherwise.
What occurred in the present case plainly involved an interference with the fairness of the trial, whether it should be characterized as procedurally or otherwise irregular. Because of the repetition of the conduct, and the trial judge's abstention from reproof and checking of it, it can only be described as significant. At one end of the scale, the relevant conduct can be seen to have posed a real risk of a wrongful conviction. At the other end, it is difficult to see how it could have done otherwise than to prejudice the jury against the appellant.
Justice is to be administered according to law. Justice, in strict terms, miscarries whenever there is a departure from proper process. Not every such departure will necessarily produce a substantial miscarriage of justice When however there is a departure from what the law requires, an appellate court, although it does not act upon a presumption that the departure has necessarily produced a substantial miscarriage of justice, proceeds upon the basis that, the accused having been denied a trial according to law, he or she may well have been the subject of such a miscarriage.

As we are of the opinion that the entry of a verdict of acquittal by this Court is not justified, and that there should be an order for a retrial, it is necessary to consider the other grounds of appeal which raise questions as to the directions appropriate to the offences of which the appellant was convicted and which will be required to be given at a retrial.
Two of the other grounds of appeal involve consideration of the complainant's intellectual capacity. The case for the prosecution at trial was put on the basis that the complainant lacked the cognitive capacity to give consent to sexual intercourse or other sexual activity, and that the appellant must have known that the complainant was intellectually impaired. It was also argued by the prosecution that it had discharged the onus of negativing the defence of honest and reasonable mistake (as to the complainant's capacity to consent) under s 24 of the Criminal Code (Q). That section provides:

(1) A person who does or omits to do an act under an honest and reasonable, but mistaken, belief in the existence of any state of things is not criminally responsible for the act or omission to any greater extent than if the real state of things had been such as the person believed to exist.

(2) The operation of this rule may be excluded by the express or implied provisions of the law relating to the subject."

In a trial such as the present, the prosecution has to prove beyond reasonable doubt the happening of the events giving rise to the alleged criminal conduct. In that respect, the onus rests on the prosecution throughout. It obliges the prosecution to prove all relevant acts and omissions beyond reasonable doubt. At the trial, properly, the prosecutor did not contest that this was so. The onus, in relation to belief of intellectual impairment or not, however, lies squarely upon an accused. This is no doubt because of the need for special protection of intellectually impaired persons. The Criminal Code nonetheless does not treat consensual sexual activity with such a person as an offence of absolute liability: an accused will be entitled to an acquittal if he can prove a negative, a matter notoriously more difficult to prove than a positive; that he believed on reasonable grounds that the complainant was not intellectually impaired.
Section 229F of the Criminal Code defines an intellectually impaired person in this way:

A person is an intellectually impaired person if the person has a disability -

(a) that is attributable to an intellectual, psychiatric, cognitive or neurological impairment or a combination of these; and

(i) a substantial reduction of the person's capacity for communication, social interaction or learning; and

Section 208(4) of the Criminal Code refers to the belief of an accused person. It provides as follows:

"(4) It is a defence to a charge of an offence defined in subsection (1)(c) or (d) to prove -

(a) that the accused person believed on reasonable grounds that the person was not an intellectually impaired person; or

(b) that the act that was the offence did not, in the circumstances, constitute sexual exploitation of the intellectually impaired person."

The trial judge here defined intellectual impairment for the jury. It would have been better, however, if he had sought to relate each of the necessary components of the definition directly to the evidence in the case so as to emphasize to the jury that the appellant's defence, the onus lying upon him, could succeed if they were satisfied on the balance of probabilities that the appellant believed that the complainant was not intellectually impaired. In this regard the jury's attention would need to be drawn to the apparently normal conversations that the appellant had had with the complainant, that is to say her not substantially reduced capacity for communication, her mature appearance, her ability to interact with him, and the absence, so far as he was aware, of her need for support, and in particular his evidence in cross-examination about these matters that we have set out.
There are varying degrees of belief just as there are varying degrees of consciousness, cognition, awareness, sophistication, experience, maturity, gullibility and naivety. A person may understand some matters very well and others barely at all. In general, people are entitled to believe what they have no reason to suppose to be otherwise or what it would not occur to them to question. The presence or absence of a belief may be a matter of inference. In Jiminez v The Queen[23] the majority judgment of this Court pointed out that the absence of a warning that a person was too fatigued to drive and might fall asleep, laid a foundation for an honest and reasonable belief that it was safe for an accused driver to continue driving[24]. Here the appellant's evidence was that he thought the complainant to be fine. He denied that he had reason "to believe, to understand, to apprehend, to comprehend, to realize that [the complainant] was an intellectually impaired person". She conversed with him about her interests and invited him to her house. She was physically mature. She spoke normally except for a slight accent and lisp. On the appellant's version she invited sexual overtures. This evidence did lay a foundation for a submission and directions of the explicit kind to which we have referred, as to a belief of the appellant that the complainant was not intellectually impaired. Having regard to the failure of the appellant's counsel to seek any redirections at trial, we do not consider that it is necessary for us to decide whether an appeal would be allowed on a challenge to the trial judge's directions on this issue. However, on any retrial, depending upon how the evidence falls out, directions should be given which give effect to what we have said.

We would therefore allow the appeal; set aside order 1 of the orders of the Court of Appeal; order that the convictions of the appellant entered by the District Court of Queensland be quashed; and order a retrial of the offences of which the appellant was convicted.
HAYNE J. The appellant was indicted in the District Court of Queensland on three counts of rape, one count of indecent dealing with an intellectually impaired person, and one count of sodomy of an intellectually impaired person. The same person was alleged to be the victim of all the offences charged. The first count of rape was alleged to arise out of an incident that had occurred in a park where the complainant and the appellant had each been walking a dog; the other counts concerned events occurring some days later at the complainant's home.
The appellant pleaded not guilty. There was no substantial dispute at trial that the complainant was an intellectually impaired person. There was no substantial dispute that, on the occasion which was the subject of the first charge, the appellant had digitally penetrated the vagina of the complainant. There was no substantial dispute that some days later the complainant had invited the appellant to her home and that they had had sexual intercourse there. The appellant denied any anal penetration. The principal live issues at trial were issues about consent, and whether the appellant reasonably believed the complainant was not intellectually impaired.
At trial, the appellant was convicted of the first count of rape (the digital penetration that took place in the park). He was acquitted of the other two counts of rape, the count of sodomy and the count alleging indecent dealing, but the jury returned verdicts of guilty to three alternative, lesser, offences: two offences of unlawful carnal knowledge with an intellectually impaired person, and an offence of exposing such a person to an indecent act.
The appellant appealed to the Court of Appeal of the Supreme Court of Queensland against his convictions, and against the sentences imposed by the trial judge. His appeal against conviction was dismissed; his appeal against sentence was allowed[25]. By special leave, he has appealed to this Court against the dismissal of his appeal against conviction.
The appellant's complaints in this Court focused chiefly upon two matters. Although not expressed this way in the notice of appeal, it is convenient to describe his principal contentions in the terms of the relevant appeal provision of the Criminal Code (Q) (s 668E). First, he alleged that there was "on any ground whatsoever ... a miscarriage of justice"[26] because the prosecutor's cross‑examination of the appellant at trial was such as to make his trial unfair. Secondly, he alleged that there was a "wrong decision of [a] question of law"[27] because insufficient and incorrect directions were given to the jury. In addition to these two submissions, to which most attention was directed in oral argument, the appellant submitted that there was "on any ground whatsoever ... a miscarriage of justice" because the conviction was unsafe and unsatisfactory. None of the matters raised by the appellant provides a sufficient basis for disturbing the order of the Court of Appeal dismissing the appeal against conviction. The appeal to this Court should be dismissed.

A criminal trial in Australia is an accusatorial[28] and adversarial[29] process. In that process, prosecuting counsel has a role that is bounded by long‑established duties and responsibilities[30]. Those duties and responsibilities are summarised when it is said that "[t]he duty of prosecuting counsel is not to obtain a conviction at all costs but to act as a minister of justice"[31]. In the Supreme Court of Canada, Rand J described[32] the role of the prosecutor as being:

"not to obtain a conviction, it is to lay before a jury what the Crown considers to be credible evidence relevant to what is alleged to be a crime. Counsel have a duty to see that all available legal proof of the facts is presented: it should be done firmly and pressed to its legitimate strength but it must also be done fairly. The role of prosecutor excludes any notion of winning or losing; his function is a matter of public duty than which in civil life there can be none charged with greater personal responsibility. It is to be efficiently performed with an ingrained sense of the dignity, the seriousness and the justness of judicial proceedings." (emphasis added)

A central, even the central, element in that role is "ensuring that the Crown case is presented with fairness to the accused"[33].

The prosecution case is to be presented in the context of an adversarial process in which each side "is free to decide the ground on which it or he will contest the issue, the evidence which it or he will call, and what questions whether in chief or in cross‑examination shall be asked"[34]. But again, there are boundaries to that process. The choices that have been described are to be made "subject to the rules of evidence, fairness and admissibility"[35]. As Dawson J said in Whitehorn v The Queen[36]:

"A trial does not involve the pursuit of truth by any means. The adversary system is the means adopted and the judge's role in that system is to hold the balance between the contending parties without himself taking part in their disputations." (emphasis added)

It is not for the judge to attempt to remedy the deficiencies of a party's case. As was pointed out in Whitehorn[37], and earlier in Richardson v The Queen[38], the judge will frequently lack the knowledge and the information that would be necessary to making a decision about whether and how any deficiency would be remedied. But it is for the judge to "hold the balance between the contending parties". It is for the judge to ensure that the trial is conducted fairly.

Unfairness may take many forms. Often what is unfair will constitute a departure from the ordinary rules that ensure the orderly conduct of a trial. Those rules encompass not only the rules of evidence but also such diverse matters as when and how counsel may address the judge and the jury. This is not to say that every departure from those rules is to be branded as causing unfairness. But, because the rules of orderly procedure are designed to safeguard the fairness of the proceedings, what is unfair will often be a departure from those rules.
In the present case, the appellant's complaint of unfairness focused upon what happened when the trial prosecutor was cross‑examining him. He submitted that the cross‑examination "was designed unfairly to undermine the appellant's credibility and included improper questions, in the sense that many questions were confusing, harassing, oppressive and repetitive" (emphasis added). He further submitted that the trial prosecutor "expressed or implied personal opinions and made impermissible comment". The text of the relevant passages from the trial transcript appears in the reasons of Kirby and Callinan JJ and it is unnecessary to repeat it here.
The sting in the first of the propositions advanced by the appellant lies in the word "unfairly". There is no doubt that the trial prosecutor set out to undermine the appellant's credibility, but it was an essential part of the prosecutor's function to test the credibility of the account which the appellant gave. Was that done unfairly?
It is important to notice that no objection was made at trial to the questions that the trial prosecutor put to the appellant. In particular, it was not said that any question, or series of questions, was confusing or oppressive. None was said to be harassing or repetitive. Failure to object to the questions at trial does not bar the appellant from complaining, on appeal, that the trial was unfair. Not least is that so because it must be recognised that counsel for an accused person may well hesitate before objecting to a line of questioning put in cross‑examination of the accused, lest it appear to the jury that counsel feels a need to protect the witness. But responsibility for deciding whether objection should be taken to the way in which a question is put to a witness, or to the conduct of opposing counsel, is a responsibility that rests primarily with counsel, not with the judge. And where, as here, the cross‑examination was interrupted by an adjournment, it is open to counsel for an accused to make any necessary protest in the absence of the jury and without further interruption of the cross‑examination. But no such objection or protest was made in this case.

The appellant made three complaints about the directions that the trial judge gave the jury. First, he submitted that there was a failure to give adequate directions "on the question of consent as it related to cognitive capacity and intellectual impairment". Secondly, he submitted that the jury should have been told that "if the appellant honestly and reasonably believed that the complainant's capacity for communication, social interaction or learning was not substantially reduced, or, if he reasonably and honestly believed that the complainant was not a person needing support, he was entitled to be acquitted". The third complaint was related to the second, and was that flow charts given to the jury as part of the trial judge's directions "were inadequate in that they did not include a reference to an honest and reasonable but mistaken belief or to any defences available". Each of these arguments requires consideration of the central provisions of the Criminal Code that were engaged in this matter. Each of them also requires the proper identification of "the real issue or issues in the case"[41].
At first sight, identifying those issues in this case seems difficult. The indictment charged five counts. There were several statutory alternative offences that had to be considered. Several provisions of the Criminal Code were directly or indirectly engaged in the matter. But by the time the trial judge came to direct the jury, the real issues to be considered by the jury were more confined than might have been the case.
As was said at the start of these reasons, there was no substantial dispute about whether the complainant was an intellectually impaired person. There were some significant factual disputes, including whether, as the charge of sodomy alleged, there had been an incident of anal penetration. There were some differences about what exactly had happened at the time of the digital penetration in the park. There was a dispute about whether the complainant had suggested to the appellant that he "bring protection" when he came to her home. But apart from these particular factual disputes, the issues that had to be considered by the jury related chiefly to whether the complainant consented to the particular acts in question, what the appellant knew or believed about her consent, and what the appellant knew or believed about her intellectual impairment.
Three statutory concepts were engaged: the Code's definition[42] of "consent", in connection with the offence of rape, as "consent freely and voluntarily given by a person with the cognitive capacity to give the consent", the Code's general provision[43] about mistake of fact, and the provision[44] that it is a defence to a charge of certain offences of sexual misconduct towards an intellectually impaired person that the accused "believed on reasonable grounds that the person was not an intellectually impaired person".

"It is a defence to a charge of an offence defined in this section to prove -

(a) that the accused person believed on reasonable grounds that the person was not an intellectually impaired person; or

(b) that the doing of the act or the making of the omission which, in either case, constitutes the offence did not in the circumstances constitute sexual exploitation of the intellectually impaired person."

It was not disputed that the burden of proving a defence under this section was on the defendant, and it was not disputed that the standard of proof of the defence was the balance of probabilities.

At his trial, the appellant submitted, among other things, that he established a defence to all of the offences under s 216 that the jury was called on to consider. He submitted that he had established a defence by showing that he had believed at the time, on reasonable grounds, that the complainant was not an intellectually impaired person.
The appellant did not give evidence that he had actively turned his mind to any question about the intellectual capacity of the complainant at any time before or during the events that gave rise to the charges. It would have been forensically difficult for the appellant if he had given evidence that he had thought about the question. Evidence of that kind could only provoke the further questions: Why? What was it about the complainant that made you think about this subject? Be this as it may, the highest point to which the appellant's evidence rose on this topic was when, in answer to a question from the trial judge, ("Now, tell me more about her. How did she appear to you? How was she talking to you?") the appellant said "Fine. She was friendly, confident. She - she seemed fine. She was attractive. I just - we just were talking." Although the trial judge sought to have the appellant expand upon what he meant by the word "fine", the most that the appellant said was "She seems fine, she seems okay."
The appellant contended that the trial judge should have instructed the jury to consider the appellant's belief by reference to the two separate elements of the definition of "intellectually impaired person". That is, the appellant submitted that the trial judge should have directed the jury to consider whether the appellant had either a belief that the complainant's capacity for communication, social interaction or learning was not substantially reduced, or a belief that the complainant was not a person needing support. There may be cases where such a direction would be appropriate. This was not one of them. The evidence which the appellant had given on this topic did not provide a basis for the jury to consider questions refined to the degree suggested. All that he had said was that she seemed "fine". The issue thus presented was sufficiently identified by asking whether the defendant had established to the requisite standard that he believed her not to be an intellectually impaired person.
Nor was it necessary to direct the jury, as the appellant submitted, that the question was one of "subjective" as opposed to "objective" belief. Even if it is possible to draw such a distinction, attempting to do so in this case would have introduced needless confusion. The statutory inquiry was about the appellant's belief. The trial judge made plain to the jury that this was the question to consider.

There were many respects in which the cross-examination of the appellant was in breach of ethical duties flowing from the position of the cross-examiner as counsel for the prosecution, and in breach of other ethical duties. For present purposes, what is important is that those breaches were also breaches of rules established by the law of evidence. While breaches of these evidentiary rules do not often result in appeals being allowed, while there are relatively few reported cases about them, and while writers have given less attention to them than to more fashionable or interesting subjects, there is no doubt that they exist and no doubt that they are well settled.
They are rules which necessarily developed over time once it came to be established that oral evidence should be elicited, not by means of witnesses delivering statements, and not through questioning by the court, but by means of answers given to a succession of particular questions put, usually by an advocate, and often in leading form. A cross-examiner is entitled to ask quite confined questions, and to insist, at the peril of matters being taken further in a re-examination which is outside the cross-examiner's control, not only that there be an answer fully responding to each question, but also that there be no more than an answer. By these means a cross-examiner is entitled to seek to cut down the effect of answers given in chief, to elicit additional evidence favourable to the cross-examiner's client, and to attack the credit of the witness, while ensuring that the hand of the party calling the witness is not mended by the witness thrusting on the cross-examiner in non-responsive answers evidence which that witness may have failed to give in chief. To this end a cross-examiner is given considerable power to limit the witness's answers and to control the witness in many other ways.
"Cross-examination is a powerful and valuable weapon for the purpose of testing the veracity of a witness and the accuracy and completeness of his story. It is entrusted to the hands of counsel in the confidence that it will be used with discretion; and with due regard to the assistance to be rendered by it to the Court, not forgetting at the same time the burden that is imposed upon the witness."[55] Hence the powers given to cross-examiners are given on conditions, and among the relevant conditions are those which underlie the rules of evidence contravened in this case.

The most striking characteristic of the cross-examination in this case was its wild, uncontrolled and offensive character.
A prosecutor must "conduct himself with restraint and with due regard to the rights and dignity of accused persons. A cross-examination must naturally be as full and effective as possible, but it is unbecoming in a legal representative - especially in a prosecutor - to subject a witness, and particularly an accused person who is a witness, to a harassing and badgering cross-examination."[56] One reason why there is a rule prohibiting this type of questioning was put thus by Wigmore[57]:

"An intimidating manner in putting questions may so coerce or disconcert the witness that his answers do not represent his actual knowledge on the subject. So also questions which in form or subject cause embarrassment, shame or anger in the witness may unfairly lead him to such demeanor and utterance that the impression produced by his statements does not do justice to his real testimonial value." (emphasis in original)

Another was advanced by Lord Langdale MR when he deprecated "the confusion occasioned by cross-examination, as it is too often conducted", for it tended to "give rise to important errors and omissions"[58]. Yet another was suggested by an American judge: "a mind rudely assailed, naturally shuts itself against its assailant, and reluctantly communicates the truths that it possesses."[59]

In this case the questioning was conducted "without restraint and without the courtesy and consideration which a witness is entitled to expect in a Court of law", and, as a result, it was "indefensible"[60]. The cross-examination was improper because it was "calculated to humiliate, belittle and break the witness"[61]. Its tone "was often sarcastic, personally abusive and derisive"[62]. It resorted to remarks "in the nature of a taunt"[63]. It amounted to "bullying, intimidation, personal vilification or insult", none of which is permissible[64].
The cross-examination not only offended these common law rules. Many of the questions were annoying, harassing, intimidating, offensive or oppressive, contrary to s 21 of the Evidence Act 1977 (Q)[65].

The cross-examination also contravened the rules of evidence in that many things said by the cross-examiner were not questions at all. To adopt the language of the Ontario Court of Appeal, counsel for the prosecution infringed the rules of evidence when he "regularly injected his personal views and editorial comments into the questions he was asking"[66]. One vice of comments made in the course of questioning is that although they may be potentially damaging in the jury's eyes, they are not questions, and thus the witness has no opportunity of dealing with the sting in the comments. Another vice is that the jury may regard counsel as a person of special knowledge and status and therefore pay particular regard to the comments - particularly where it is counsel for the prosecution who chooses "to throw the weight of his office" into the case[67]. The time for comments, at least legitimate ones - for disparaging comments based on evidence or the lack of it can be legitimate - is the time of final address[68]. "Statements of counsel's personal opinion have no place in a cross-examination."[69] The role of prosecution counsel in the administration of justice should not be "personalized"[70]. Their own beliefs should not be "injected" into the case[71]. Thus in R v Hardy[72] junior counsel (the future Gibbs J) for one of the accused asked a witness who had attended certain allegedly seditious meetings: "Then you were never at any of those meetings but in the character of a spy?" The future Lord Ellenborough CJ, appearing for the prosecution, objected to this line of questioning. Eyre LCJ said to defence counsel:

"[Y]our questions ought not to be accompanied with those sort of comments: they are the proper subjects of observation when the defence is made. The business of a cross-examination is to ask to all sorts of acts, to probe a witness as closely as you can; but it is not the object of a cross-examination, to introduce that kind of periphrasis as you have just done."

After junior counsel for the accused sent for leading counsel (the future Lord Erskine LC), and the point was debated further, Eyre LCJ upheld the objection[73]:

"I think it is so clear that the questions that are put are not to be loaded with all of the observations that arise upon all the previous parts of the case, they tend so to distract the attention of every body, they load us in point of time so much, and that that is not the time for observation upon the character and situation of a witness is so apparent, that as a rule of evidence it ought never to be departed from ...".

Comments are particularly objectionable when they are sarcastic or insulting. They are even more objectionable when they are statements indicating the personal belief of prosecution counsel in the credibility or guilt of the accused: that is not something to be said in address, and a fortiori is not something to be said during questioning.

Partly by reason of the interspersing of both comments and questions between the accused's answers, and partly by reason of other defects in the form of the questions, some "questions" asked during this cross-examination were not single questions, but were compound questions. "A compound question simultaneously poses more than one inquiry and calls for more than one answer. Such a question presents two problems. First, the question may be ambiguous because of its multiple facets and complexity. Second, any answer may be confusing because of uncertainty as to which part of the compound question the witness intended to address."[74] But compound questions have additional vices. It is unfair to force a witness into the position of having to choose which questions in a compound question to answer and in which order. Cross-examiners are entitled, if they can, to frame questions so as to seek a particular answer - either "Yes" or "No". Even though the answers desired by the cross-examiner to a compound question may be all affirmative or all negative, the witness may wish to answer to some affirmatively and some negatively. To place witnesses in the position of having to reformulate a compound question and answer its component parts bit by bit is unfair to them in the sense that it prevents them from doing justice to themselves. Some "questions" asked in this case contained at least four questions within them.

On occasion during his cross-examination the accused's answers were cut off either by a comment or by some further question even though it was clear that there was more which the accused wished to say. "Evidence should ordinarily be given without interruption by counsel."[75] The cutting off of an answer by a further question, though always to be avoided as far as possible, can happen innocently when a questioner is pursuing a witness vigorously and the witness pauses in such a fashion as to suggest that the answer is complete; it can happen legitimately if a witness's answer is non-responsive. But very few of the interruptions here can be explained away on these bases. They were usually interruptions of responsive answers, often by offensive observations. The rule against the cutting off of a witness's answer follows from the encouragement which the law gives to short, precise and single questions. It is not fair to ask a question which is disparaging of or otherwise damaging to a witness and to cut off an answer which the cross-examiner does not like. The right of a cross-examiner to control a witness does not entail a power to prevent the witness from giving any evidence other than that which favours the cross-examiner's client.

The cross-examiner on occasion alleged that the accused was inventing evidence when in fact the proposition supposedly invented corresponded with evidence given by the complainant in the prosecution case. The cross-examiner also put implicitly unfounded assertions that the accused was being evasive. And the cross-examiner, in putting a question about the accused's dishonesty, wrapped up in it an assumption that there had been an earlier and different piece of dishonesty.
A question put in chief which assumes a fact in controversy is leading and objectionable, "because it affords the willing witness a suggestion of a fact which he might otherwise not have stated to the same effect."[76] While leading questions in the cross-examination of non-favourable witnesses are not intrinsically objectionable, "[w]itnesses should not be cross-examined on the assumption that they have testified to facts regarding which they have given no testimony. Such questions have a tendency to irritate, confuse and mislead the witness, the parties and their counsel, the jury and the presiding judge, and they embarrass the administration of justice."[77] This is because a leading question put in cross-examination which assumes a fact in controversy, or assumes that the witness has in chief or earlier in cross-examination given particular evidence which has not been given, "may by implication put into the mouth of an unwilling witness, a statement which he never intended to make, and thus incorrectly attribute to him testimony which is not his."[78] A further vice in this type of questioning is: "An affirmative and a negative answer may be almost equally damaging, and a perfectly honest witness may give a bad impression because he cannot answer directly, but has to enter on an explanation."[79] Questions of this character are misleading and confusing, within the meaning of both the statutory and common law rules.

Another vice in the questioning in this case stemmed from the fact that some of the questions and observations of counsel for the prosecution did not seek to elicit factual information, but rather provided merely an invitation to argument[80]. Examples include: "That doesn't tell us much, does it?", "Look, I'm giving you every opportunity?", "I'll shift to another topic whenever you're prepared to finish it", and "We want honesty at all times, of course". In form these remarks seemed apt to trigger a debate about how much the accused's hearers had been told, whether he was being given every opportunity, whether he had finished a topic, and whether he was being honest. The vice in a particular type of argumentative cross-examination was described thus by the English Court of Appeal:[81]

"One so often hears questions put to witnesses by counsel which are really of the nature of an invitation to an argument. You have, for instance, such questions as this: 'I suggest to you that ...' or 'Is your evidence to be taken as suggesting that ...?' If the witness were a prudent person he would say, with the highest degree of politeness: 'What you suggest is no business of mine. I am not here to make any suggestions at all. I am here only to answer relevant questions. What the conclusions to be drawn from my answers are is not for me, and as for suggestions, I venture to leave those to others.' An answer of that kind, no doubt, requires a good deal of sense and self-restraint and experience, and the mischief of it is, if made, it might very well prejudice the witness with the jury, because the jury, not being aware of the consequences to which such questions might lead, might easily come to the conclusion (and it might be true) that the witness had something to conceal. It is right to remember in all such cases that the witness in the box is an amateur and the counsel who is asking questions is, as a rule, a professional conductor of argument, and it is not right that the wits of the one should be pitted against the wits of the other in the field of suggestion and controversy. What is wanted from the witness is answers to questions of fact."

Like several other of the rules discussed above, the rule against argumentative questioning rests on the need not to mislead or confuse witnesses.

It is not unique in the law of evidence to find that the more closely the rules for admissibility are complied with, the greater the utility of the testimony from the point of view of the party eliciting it. It is certainly the case in this field. The rules permit a steady, methodical destruction of the case advanced by the party calling the witness, and compliance with them prevents undue sympathy for the witness developing. It is perfectly possible to conduct a rigorous, testing, thorough, aggressive and determined cross-examination while preserving the most scrupulous courtesy and calmness. From the point of view of cross-examiners, it is much more efficient to comply with the rules than not to do so.

It was open to counsel for the accused to object to the questions criticised above, but there was no objection. He could well have judged that it was prudent not to do so. However, the permissibility of questioning of the type criticised in this case does not depend solely on whether there are objections from counsel representing the party calling the witness. "The failure of counsel to object does not ... give Crown counsel carte blanche ..."[82]. Trial judges have a responsibility independently of objections to prevent this type of questioning being employed[83]. "If counsel begin to misbehave [the trial judge] must at once exert his authority to require the observance of accepted standards of conduct."[84] Here the trial judge occasionally intervened to control the witness's answers, but never to control counsel's questions.

While the breaches of exclusionary rules discussed above were capable of placing the accused in an unfair position, taken as a whole the breaches generated neither unfairness nor a miscarriage of justice. That is so partly because, despite interruptions, the accused was able to get his version of events across. It is so partly because at least the questions (as distinct from the comments) were not irrelevant and hence did not influence the jury towards an illogical approach to the issues. It is so partly because the uncontrolled ineptness of the questioning was such as to attract sympathy to the accused. Evidently designed to disparage and humiliate the accused, the questioning is likely to have rehabilitated him in the jury's eyes as he struggled with success towards advancing an account of the events to which the questioning related. The very egregiousness of the conduct generated safeguards against the dangers inherent in it. "[T]he adoption of an unfair conduct in cross-examination has often an effect repugnant to the interests which it professes to promote."[85] Here the overly aggressive and unfair approach of the cross-examiner was one which was likely to have generated sympathy in the jury for the accused. Even if it did not, the accused showed himself capable of pointing out the defects of the cross-examination in a dignified way, and overcoming them.
The disapproval of the conduct of this trial to be found in all the judgments of this Court may discourage and prevent its repetition. But it is not the function of the Court to seek to discourage and prevent repetition by allowing an appeal unless there has been a miscarriage of justice. Despite that fact, dismissal of the appeal is not to be taken as complaisance in the conduct examined.

Wigmore, Evidence in Trials at Common Law, Chadbourn ed (1970), vol 3, at 171 [780]. The rule does not forbid questions being put to experts on assumed facts, controversial though the assumption may be: there is here no question of trapping or misleading the witness, because the witness is not invited to accept the truth of the assumption. Nor does the rule forbid counsel putting suggestions to witnesses that propositions are true which counsel is not in a position to support by calling evidence, so long as counsel believes in good faith and on a reasonable basis that the proposition is correct: Fox v General Medical Council [1960] 1 WLR 1017 at 1023; [1960] 3 All ER 225 at 230 per Lords Radcliffe, Tucker and Cohen; R v Lyttle (2004) 180 CCC (3d) 476 at 489-493 [47]-[66]; Ebanks v The Queen [2006] 1 WLR 1827 at 1839-1844 [26]-[31]. ↑
