The federal Liberals tabled a bill on Friday meant to eliminate "self-induced extreme intoxication" as a legal defence for violent crimes. The move is in response to a Supreme Court ruling last month that found a previous change to the Criminal Code preventing the defence from being used was unconstitutional. This time, the Liberals are amending the code so a person could be held responsible for violence committed in a state of extreme intoxication, if they ended up in that state through their own criminal negligence.
