It really depends *how* drunk.
Too drunk to make an informed choice on whether to have sex or not? Then yes, that could be considered rape as you would have seen the girl was unaware of what was going on and so couldn't possibly have said yes.
This is a shady area of the law though, because it is difficult to prove what state of mind someone was in when they were drunk, especially if there are no witnesses..
So best avoid these situations all together, anyone that is drunk should be put in a taxi home with taxi fare, their keys, and hangover tablets in their pocket
Yes I would say.
