Okay. Very good.
I was saying, to the extent that the accused wanted to raise intoxication as a way of showing that they lacked one of the elements of the events. Then, if it was what the law calls a specific intent defence, that would be fine. So, if you were charged with murder because of intoxication and you didn't have the capacity to form a sufficient degree of intent, then it could reduce it to manslaughter, which is a general intent defence. However, when it came to general intent defences, because of section 33.1, you would be foreclosed from arguing that you lacked the intent necessary for the offence or that you had committed the offence involuntarily.
It was a fairly short process, and the focus of the prosecution would simply be whether the Crown could make out the offence, and that defence was not available...nowadays.
