I just read this elsewhere, perhaps it has a bearing on the discussion. Please don't attack me.....I have my own views, not expressed here.
"Admissibility of this or that piece of evidence is a tricky, complex subject in English Law at the best of times, but never more so than in cases of historical abuse and adult rape. A few of us knew, for instance, that the woman who brought this charge had a documented history of hotel encounters spookily identical to the format (à trois) and ‘come-on’ wording of sexual events that got Evans and his friend into trouble. Further, she had done the same thing two days before and two days after the Evans encounter.
That doesn’t prove Evans thought he had consent in this case. But without collusion, two other men came forward to say she had tried the exact same modus operandum to threaten them. It was, therefore, more than enough to cast a shadow of doubt; and in English Law, a shadow of doubt cannot be left".
