In this case, Mr Worsnop says that he believed that [TH] consented to the sexual penetration_._ He said she consented to having oral sex with him after he offered it to her. You will need to make an assessment of this evidence in order to determine whether the prosecution has proved this fourth element; that is, that the accused was aware that the complainant was not, or might not be, consenting.
You must consider any evidence concerning Mr Worsnop's belief about [TH's] consent, and determine whether the accused actually held it. Remember that the accused does not have to prove this. The law says that the accused's belief in consent does not need to be reasonable, but in deciding whether or not Mr Worsnop in fact held that belief, you must consider whether his alleged belief that [TH] was consenting was reasonable in all the circumstances.
That reasonableness, or unreasonableness, of Mr Worsnop's alleged belief, is no more than a guide to help you decide whether or not the accused had that belief.
However, in considering whether the belief was reasonable in all the circumstances, the law says you must have regard to whether the accused took any steps to find out whether the complainant was consenting and, if so, the nature of those steps.
If you are satisfied that [TH] was not consenting because you found that she submitted because of force, then in considering whether the belief in consent was reasonable, you must have regard to whether or not Mr Worsnop was aware that she had submitted because of force.
However, you should not focus on only one factor and ignore the rest. You must consider all the evidence, including anything said or done in the circumstances.
Evidence of Mr Worsnop's belief in consent must be taken into account by you when determining whether the prosecution has proved beyond reasonable doubt that the accused was aware that the complainant was not, or might not be, consenting. Even if you find that the accused did have such a belief, you will still need to decide whether the prosecution has proved this fourth element. You might find that the accused believed the complainant was consenting, but still be satisfied, beyond reasonable doubt, that the accused was aware of the possibility that the complainant was not consenting. In that case the fourth element would be met.[1]
