"Having found what you did with M's vagina and the findings that you made there, does that help you decide whether it is more likely that the anal fissures were caused by constipation or by sexual contact of some sort?"
"Yes, the genital findings as well as the history given by M and the video interviewing lead me to think that they are ... it is significant finding of sexual abuse rather than constipation."
"... you can have constipation by a child not reported to any carers and subsequently forgotten by the child of being of any relevance and this is the problem in this case. If you have more injuries or changes to the anus it supports penetration. Two simple fissures by themselves could be the result of constipation alone, reported or unreported, and then that is again still consistent with the allegation made by the child of intercrural intercourse taking place."
"Members of the jury, Dr Kugan and Dr Rouse were the medical experts and they were clear on one thing. In their view sexual abuse had taken place."
"What does this medical evidence mean, if you accept it? It means that M had been involved, does it not, in sexual activity?"
"You will consider that but how do you account for the medical evidence? If you accept that then M's account as to what happened is given strong support. The medical evidence is repeated sexual interference. Do you reject that, too?"
"... has M made up a pack of lies and falsely accused an innocent young man? Might she have done? If so acquit Colin. Have the doctors got it wrong? Might they have found a series of innocent causes which have come together coincidentally or by chance to support her account or might someone else have interfered with her?"
"Both Dr Kugan and Dr Rouse were satisfied that M had been sexually interfered with. ... Both doctors agreed that the anal injuries, the two fissures, were caused by penile penetration. But both also agreed that the sexual activity described by M was, in fact, intercrural intercourse, rather than sexual intercourse as we all understand it."
"It may be that, save in relation to counts 1 and 2, you will have little difficulty in deciding what happened to M; but that is a matter for you. The real issue may be: who did these things to her, the repeated sexual interference over a period, as described by the medical experts? Was it Colin, when babysitting, as M insists; or, if these things happened, might they have been done by someone else?"
"Could it, realistically, have only been Colin, if you accept the evidence of the doctors?"
"7. Opinion The examination of M occurred in 1997. Although this is only 12 years ago considerably more information is available now to guide interpretation of genital findings than was available in 1997. The RCP [Royal College of Paediatricians and Child Health] published guidance in 1997... This was withdrawn several years ago. Revised guidance was published in April 2008 and this was based on an extensive evidence based review of the published literature. It clarifies that many findings previously considered diagnostic or suggestive of sexual abuse are non-specific (they occur equally often in children carefully screened for non-abuse)."
"The physical findings which Dr Kugan described, and upon which both she and Dr Rouse relied in coming to their opinion, are not diagnostic of sexual abuse. I would regard them within the range seen in non-abused children. I would therefore regard them as normal or non specific (no more common in abused than non abused girls)."
"Could it realistically have only been Colin if you accept the evidence of the doctors?"
"A substantial miscarriage of justice will actually occur if fresh, admissible and apparently credible evidence is admitted which the jury convicting a defendant had no opportunity to consider but which might have led it acting reasonably to reach a different verdict if it had had the opportunity to consider it."
