The question of penetration and the medical evidence
42The complainant's evidence was that the appellant's penis was inserted "fully" into her vagina in both of the incidents the subject of the charges on indictment.
43In her interview with police she said in relation to the first incident:
Q: OK. And then what's happened after he's taken your pants off?
A: Um, he injected his penis into my vagina.
Q: OK. And do you know if his penis went fully into your vagina or ...
A: Ah, yep.
Q: ... just a little bit or something different?
A: Ah, fully .
Q: Fully. OK. And do you remember how that made you feel?
A: Um, uncomfortable, it was really uncomfortable and ...
(emphasis added)
44In cross-examination she confirmed (when addressing the first incident) that by the appellant's penis being "fully" in her vagina she meant that the whole of his penis was inside her vagina:
Q: Do you say, do you, that [the appellant] put his penis in your vagina on this occasion?
A: Yes, [he] put his penis into my vagina.
Q: Do you have an actual recollection of that?
A: Yes.
Q: You say that he put his penis fully into you. Is that right?
A: Yes.
Q: You understand what fully means? That means his whole penis in your vagina . Is that what you meant?
A: Yes.
(emphasis added)
45She went on to say she thought the appellant's penis was soft when it was inside her vagina during the first incident. She described his penis (when pressed in cross-examination) as white and hairy. She said he did not use lubrication:
Q: Can you recall whether the person you say assaulted you used any sort of lubrication?
A: No.
Q: You can't recall or they did not?
A: They did not.
46In relation to the second incident she said that the appellant's penis was "fully" inside her and that it was hard:
Q: OK. So when you said that he had his penis inside your vagina, was it in fully or a little bit or something else ?
A: Ah, yeah, it was in, it was in fully .
Q: OK. And can you tell me how you know that it was in fully ?
A: Um, because, like, the, like, head bit of the penis was, like, all the way in my vagina ...
...
Q: ...the second incident we spoke about at Jacaranda Drive ... when he had his penis inside your vagina ...
A: Yeah.
Q: ... was it, do you remember if it was hard or soft or something else?
A: Ah, it was hard.
Q: It was hard.
A: Yep.
(emphasis added)
47She said that lubrication was not used during the second incident and that she did not cry out despite the discomfort or pain she felt on both occasions. She gave the following evidence (in relation to the first incident):
Q: ...Did you make any noise when you were being assaulted?
A: No.
Q: You can remember not making any noise?
A: Yes.
Q: You didn't cry out at all?
A: I didn't know what was happening, so -
Q: That's not what I asked you. You didn't cry out did you?
A: No.
Q: Did you experience any pain?
A: Yes.
Q: What sort of pain?
A: I felt quite uncomfortable and scared and my vagina was actually hurting.
48She was asked the following questions by the trial judge and then cross-examining counsel:
Q: Can you describe in more detail the pain that you say you experienced?
A: It hurt when he put his penis into my vagina.
Q: This is his soft penis is it?
A: Yes.
Q: Please go on.
A: The pressure that my vagina would have been small and his penis would have been quite bigger, that it physically hurt on the inside of my vagina.
Q: I see. You say, "Would have been", do you actually remember experiencing or feeling anything? Anything different at that time?
A: I felt pain inside my vagina.
Q: So you did feel something different in your body? You say, "You didn't understand", but you did feel something in your body is that right?
A: Yes.
49The complainant did not remember experiencing any pain on urinating or any bleeding or discharge from her vagina as a result of the penetrative assaults. Her mother did not notice any blood on the complainant's underwear. She confirmed that the complainant did not complain about pain in her vagina to anyone when she was aged three to seven.
50The Crown adduced medical evidence from Dr Leonie Kirkwood, a visiting medical officer specialising in sexual assault at Tamworth Base Hospital. She examined the complainant on 2 September 2008 and made the following findings:
...Genital examination was normal. The hymen was thick and folded, which is normal in that age group. Forensic swabs and smears were not taken because of the long duration of time since the assaults. Based wholly or substantially on the above knowledge, I am of the opinion that the normal genital examination does not preclude the assaults as described to me having taken place.
51She gave the following evidence in re-examination of her approach to an examination following a complaint of sexual assault:
When I examine the female genitalia I look at the external genitalia initially, which is when we look at the mons, which is the mound at the top of the genitalia, the labia minora, which are - the labia majora, which are the lips on the outside. We look at the labia minora which are the lips on the inside. We look at the area called the posterior fourchette, which is the area where the lips join together at the back, closer to the anus. We then also look at the hymen. So that in instances of penetration, penetration may only be of the labia minora or the labia majora. Penetration does not necessarily mean full penetration of the vagina.
52She based her opinion on the time that had elapsed since the assaults and that in 70-80 per cent of cases where sexual assault involving the genital area is alleged the examination is normal. She accepted in cross-examination that the examination was also consistent with no sexual assault having occurred.
53Under cross-examination, Dr Kirkwood was asked about the effect of full penile penetration of the vagina of a 3 year old and 7 year old. She gave the following evidence:
Q: Dr Kirkwood please assume that a 3 year old female has an adult male penis inserted in her fully? Please work on that assumption? Would it be reasonable to expect the tissue of the female to be rapidly stretched beyond its elastic limits?
A: Yes.
Q: And would that produce broken blood vessels most likely?
A: Yes.
Q: Would it be most likely to cause a tear of the hymen?
A: Yes.
Q: Would it be most likely to cause obvious bleeding?
A: Yes.
Q: Is it possible in those circumstances that surgical repair would be needed?
A: That's beyond my area of expertise.
Q: Are the outcomes that I've described likely to be similar in relation to the 7 year old child in circumstances of a fully penetrated adult male penis?
A: Yes.
Q: Is a circumstance of repeated penetration, that is over a period of time of up to, if I can ask you, 13 times, is that likely to have more of a deleterious effect upon the female vagina than not?
A: Yes.
54In re-examination Dr Kirkwood confirmed that the expected damage to a child's vagina to which she referred in the above extract was based on the assumption of full penetration:
Q: Right. So there can be penetration of the female genitalia, including the insertion of a penis, which may not even get to the opening of the vagina, is that correct?
A: That is correct.
Q: So it is a matter of what perception or what is meant by full penetration as to whether it actually reaches into the vagina or is penetrating those other areas making up the genitalia, is that right? ... Is that fair to say, it is a matter of what one means when someone says full penetration?
A: That's correct.
...
Q: Right. Your definition that you work on is full penetration is penetrating through all of the organs there, is that correct?
A: That's correct.
Q: OK. So on that basis and on that understanding is when you spoke of what damage may occur to a young child, is that right, from full penetration?
A: That's correct.
55In cross-examination she agreed that while the structure of the vagina is complex, thus not permitting the allocation of simple measurements of its length or width, the vagina of a child of 3 years and/or 7 years of age would not have the capacity to comfortably accommodate the erect penis of a young male adult.
