That's literally rape. He tried to say (in England) that it wasn't rape, and that was rejected by the court. https://www.bailii.org/ew/cases/EWHC/Admin/2011/2849.html

He tried to claim that this wasn't rape in both Sweden and England (the dual criminality element which is required for extradition) and that was rejected by the court.

He was accused of having sex with someone who was asleep and therefore couldn't consent (and the lack of protection showed he was explicitly going against what he knew she wanted). This is rape in the UK and Sweden.

The first prosecutor decided to shelve the case. One of the victim's lawyers asked for this decision to be reviewed. A more senior prosecutor resumed the case.

This was before the alleged victims' lawyer asked the prosecutor to review the decision. Anyway, Assange has been sought in Sweden since 2010 for rape under mitigating circumstances, which carries a maximum sentence of four years and statute of limitations of ten years.

Sweden has a comparatively broad legal definition of rape.

My memory of accusations are they they sure meet my personal definition of rape. We may only disagree on the terminology; I trust we don't disagree that what is alleged should be a crime.
