As you will be aware, the offences in this trial are alleged to have occurred in 1990 and 1992 but you heard that [PN] did not go to police until 2005 which was up to 15 years after the first offences were alleged to have taken place. I need to give you some directions about the way in which you can use that evidence of delay. In giving you these directions, I am not suggesting that the law regards complainants in sexual cases as an unreliable class of witnesses, it does not. You are only allowed to use this evidence for a very limited purpose as a matter to be taken into account when assessing [PN's] credibility.
You may take [PN's] delay in complaining into account when assessing his credibility. If you find that that delay is inconsistent with the account of the events he has given in court, it is for you to determine whether the delay in complaint points to inconsistency by [PN]. If you would have expected a complainant in [PN's] alleged circumstances to complain about such an offence more promptly or earlier, you may find that his delay in complaining was inconsistent with the truth of his account. But in determining whether the evidence shows inconsistency, it is important that you understand that there may be good reason why a victim of sexual assault may delay or hesitate about complaining about it. These may lead you to find there is no inconsistency.
For example, the fact that he is a child. The fact that he was, he said "scared" of the accused man. The fact that his mother was still in a relationship with [the accused] up until December 2004. Those are the sorts of matters that you look at in determining whether or not it was reasonable or unreasonable for [PN] not to make a complaint to police until he did. If you find that you would have expected someone in his position to complain early, you can take that into account in determining whether that is inconsistent with the truth of what [PN] has to say, however in determining that as I said, you should take into account whether or not there were good reasons why he made those complaints until that time.
A second direction I need to give you about the delay relates to the complainant, that is [PN's] memory. Again, I am not suggesting, and it would be wrong to suggest that people who makes complaints of sexual offence are less reliable that other witnesses. These directions are solely necessary because of the delay in complaining about the offence. And one consequence of the delay is its possible effect on the reliability of [PN's] memory. And [counsel] for the accused man has spoken to you at some length about this. You will easily understand that the passage of time may affect any witness' memory. While in some cases people simply forget things, in other cases their memory may become distorted. That is, they may claim to remember things that did not really happen.
Experience has shown that human recollection is frequently erroneous and liable to distortion in this way and that the likelihood of error increases with delay. The risk is enhanced if the complainant is young at the time of the alleged offending. Recollection of events occurring in childhood is often distorted or mistaken. It is therefore important that you carefully consider not only whether [PN's] evidence is honest in the sense that he believes it to be true, but also whether it is in fact true. Whilst you use your common sense and experience in assessing the effect of the delay upon [PN's] memory, you must also consider the possibility that he honestly believes what he is saying but he is mistaken due to the distortion of his memory.
It is a matter that you take into account and it is a matter entirely for you. You do not have to find that his memory is distorted because these events occurred long ago and he was young at the time but you need to bear that in mind and look at that question in determining his evidence and determining whether you are satisfied beyond reasonable doubt of the accused man.
