Not all cases have constitutional questions that go right to the top. So there actually can be repercussions for the rest of Canada. Moreover, a lot of people all over the country interpret the Constitution one way or another. We do a lot of interpretations here in Quebec. Chief Justice Fournier talks about doctrinal texts that are mostly written by people in universities. Those interpretations do not necessarily get to the rest of Canada. Of course, there may be bilingual people elsewhere in the country who read them. That said, some constitutional interpretations rendered in Quebec, either in judgments or in doctrinal texts, certainly do not make their way all across Canada.
