Assange v Swedish Prosecution Authority [20111 EWHC 2849 (Admin) (02 November 2011)
Paragraph 86:
"..The allegation is clear and covers the alternatives; it not an allegation that the condom came off accidentally or was damaged accidentally. It would plainly be open to a jury to hold that, if AA had made clear that she would only consent to sexual intercourse if Mr Assange used a condom, then there would be no consent if, without her consent, he did not use a condom, or removed or tore the condom without her consent. His conduct in having sexual intercourse without a condom in circumstances where she had made clear she would only have sexual intercourse if he used a condom would therefore amount to an offence under the Sexual Offences Act 2003, whatever the position may have been prior to that Act."
I'm not competent at all on the subject but it doesn't seem to me the quote you present imply the comment you previously made
The UK Judge in his first extradition trial said he would be guilty of rape or sexual assault in the UK.
It seems to me that what he is saying here is that the allegation could be a sexual offense, thus it's one of his arguments to allow extradition to swede in order to permit further investigation on this plausible and relevant allegation.
If he did the same act(s) in the UK that he did in the Sweden, he would be guilty of a UK offence. It seems pretty clear to me.
"His conduct in having sexual intercourse without a condom in circumstances where she had made clear she would only have sexual intercourse if he used a condom would therefore amount to an offence under the Sexual Offences Act 2003, whatever the position may have been prior to that Act"
If he did the same acts in the UK that the prosecutor alleges that he did in Sweden. In no way is that conduct proven. In fact, it is not even demonstrated that the women in question have alleged he acted that way - at least one of them have stated she is refusing to sign the statements.
Also, the crusader for freedom has fled to a regime that is demonstrably un-free.
