Of course the outcome matters. If the conviction stands, he raped a woman; if it's quashed, he had consensual sex with woman who seemingly regretted it the following day (we've all been there). Slight difference.
I know what you're saying but strictly speaking not quite correct. If it stands, yes, he remains a convicted rapist. If it is quashed then all that means is that there is enough doubt not to be convicted. That said, the new evidence might actually prove it was consensual although I'm not sure what that could be.
His behaviour that night was disgusting but, if it is proved consensual, then it applies to all three.
It doesn't say it in the report but on the tv news, the comment was made that for the CCRC to refer it to appeal, they have to have strong grounds that the conviction will be quashed.
We'll just have to wait.
