What is so bad about it? Aside from the fact that it undermines a unified code of law that is Western, it means that political legislation will have to be passed to institute a new and exclusive Sharia. And Sharia is not a body of civil rules in Islam: it is the legal doctrine run by a Religion Organization. Thereby, the legislation would have to "cut the child in half" so that Sharia Law [not "rule"] is no longer a complete authority of itself. You would then propose two legal systems not one. And the Canadians made well have made a horrible choice to allow the cult camel into the tent by a leg or tail or indeed...a head.
