Not true. I'll take the time to llok up the case at some point but I'll give you the details.
Young man and woman get drunk. Very drunk. They have sex. The next day she acts like nothing happened and eventually the guy brings it up - she didn't even know she had had sex (she claimed). She pressed charges.
The woman's proof that she had never given consent, even though she could not remember the event even happening, was this: "I'm not that kind of person".
He was convicted based solely on her word about whether she would have given consent.
Like I said I will look for the reference when I get a chance.
