From hazy memory in at least one of cases the victim / complainant had willingly gone to bed with him but then went to sleep and woke up to find him assaulting her. I don't know much about Swedish law but in the UK I imagine that would be hard to prove in a court, as are most rape cases depressingly.
Though there may be hope:
Cricketer guilty of raping sleeping woman
Slightly different case but still. What an absolute horrible cunt btw.
