His evidence ie his testimony gave no factors in which she indicated consent, no testimony of enthusiastic participation.
Not enthusiastic participation, no, but participation, yes.
Unless you think it's okay to have sex on a woman who is not participating.
Do we know she was not participating? His testimony says otherwise ('how could I make her? it was her mouth, she was the one doing it'), and the mechanics of the situation also make this very likely.
As I have already said, you can argue that sexual ethics requires something beyond simple agreement, requiring a more positive joyful enthusiasm, enjoyment, and maybe other things perhaps, but the law's bar is set a bit lower, simply requiring consent, agreement.
And I know my opinion is not a legal opinion. Neither is yours when you raise a query with what the defence lawyer is saying or arguing. Or otherwise considering the facts and making a judgment in your own mind as to whether you think there is beyond reasonable doubt of X Y or Z. Which I am assuming you have done rather than just base your beliefs entirely on the statement that the lawyer at the end made, that this case should get a guilty verdict.
