"In my opinion [the complainant] is an unreliable witness as a result of her mental health difficulties."
"(2) The difficulty arises where there is some evidence but it is of a tenuous character, for example because of inherent weakness or vagueness or because it is inconsistent with other evidence. (a) Where the judge comes to the conclusion that the prosecution evidence, taken at its highest, is such that a jury properly directed could not properly convict upon it, it is his duty, upon a submission being made, to stop the case. (b) Where however the prosecution evidence is such that its strength or weakness depends on the view to be taken of a witness's reliability, or other matters which are generally speaking within the province of the jury and where on one possible view of the facts there is evidence upon which the jury could properly come to the conclusion that the defendant is guilty, then the judge should allow the matter to be tried by the jury." 20.

"You do not need to decide what happened with .... [a previous incident which had been introduced into evidence]. It is, however, something which with the other admissions as to [the complainant's] background that you may -- and I stress the word 'may' because it is a matter for you -- take into account when assessing the two core questions which you may think arise in this case in relation to [the complainant]. The first of those is: would she act in the way as it is suggested that she has done by the defence, in effect initiating sexual behaviour, behaving in the way that she did in the car park? And secondly: can you treat her as a reliable witness?"
"You have got the two respective cases. The prosecution case here is that you can put to one side the medical evidence. [The complainant], say the prosecution, is potentially a reliable witness. She is no different -- despite her mental health background -- from any 15 year old. It is a task which you are there for. Weigh up and assess her evidence. Weigh up and assess the defendant's evidence. Are you sure that the allegations have been proved? Yes, say the prosecution. The defence say it is far from that simple. Take as your starting point the cogent evidence of Mr Rogers. You have -- when you come to consider [the complainant] -- someone who behaves in a way that a 15 year old might not be expected to behave. She has a problem with recall. She has a problem with exaggeration. Set that as your framework, and you see the case in a different perspective. You cannot be getting close, say the defence, to being sure on her account. They say when you look at her impulsive and unusual behaviour, the version of events given by the defendant -- whilst at first blush being surprising -- is not one which you should reject out of hand, and certainly when looking at that version of events it is not an incredible tale. You are not judging him on the appropriateness of what he did, say the defence. You are saying whether you are sure these allegations are proved, and you cannot be."
"Although a specific direction was not given, the jury in the Crown's submission were well aware that the complainant's account was being criticised as exaggerated, inconsistent and implausible. To give a further direction about taking care when considering it would have been excessive."
"In R v Cannings .... a case of the alleged murder of a baby, it was said that if the outcome of the trial depends exclusively or almost exclusively on a serious disagreement between distinguished and reputable experts, it will often by unwise, and therefore unsafe, to proceed; and this was particularly so, in a field of learning, where the experts were still at the 'frontiers of knowledge'. Cannings is not, however, authority for a proposition, in cases where the issue is whether a child was the victim of a deliberate killing by its mother or had died from natural, even if unexplained, causes, that whenever there is a genuine conflict of opinion between reputable experts, the prosecution should not proceed, or should be stopped, or that the evidence of the prosecution experts should be disregarded; in Cannings, there was nothing to establish unnatural as opposed to natural death and the basis of the case depended on inferences by one group of experts which were disputed by another reasonable body of medical opinion: R v Kai-Whitewind[2005] 2 Cr App R 31 , CA."
