"[...] what is alleged here is that Mr Assange 'deliberately consummated sexual intercourse with her by improperly exploiting that she, due to sleep, was in a helpless state'"
"It is clear that the allegation is that he had sexual intercourse with her when she was not in a position to consent and so he could not have had any reasonable belief that she did."
Here's the allegation in English:
"4. Rape
On 17 August 2010, in the home of the injured party [SW] in Enkoping, Assange deliberately consummated sexual intercourse with her by improperly exploiting that she, due to sleep was in a helpless state.
It is an aggravating circumstance that Assange who was aware that it was the expressed wish of the injured party and a prerequisite of sexual intercourse that a condom be used, still consummated unprotected sexual intercourse with her. The sexual act was designed to violate the injured party’s sexual integrity."
