Couldn't happen to a nicer bloke. I think he is going to use "I was very drunk at the time" as a defence. This might work on Scotland.
I've just done Jury Service in England (Liverpool to be more exact).
The case I was on, was a sexual offence.
The judge made it clear.
All three of these things had to be true to convict.
1) We had to be 100% clear that what she said happened actually happened.
2) We had to be 100% clear that there was no consent. Consent being sober enough to know that you are giving consent as opposed to being to pissed say no.
3) That the defendant could not reasonably believe that consent had been given. Being too drunk to know whether consent has been given was no defense, because drunk people unreasonably believe all sorts of shit. And ignoring that she was drunk and therefore would struggle to give consent or say no clearly because he was too drunk to take any notice wasn't a defense.
He was acquitted because the prosecution failed to prove one or more of the three.
Mind you while we were there, a nine week trial about 2 gangland killings finished, so I was glad mine was only 3 days.
