The equality of the provinces would be adversely affected. Clearly, it means special constitutional status for Quebec - a situation unacceptable in federalist Quebec and in other parts of Canada. The debilitation of the province would continue. They would omit to say that they didn't want it in the first place.
Equality calls upon the provincial premiers and the feds to drop the idea completely.
With respect to the Supreme Court, Quebec as a distinct society wishes to ensure that it is adequately represented on the Court, which is the ultimate arbiter. We might point out that this is typical of Quebec Liberal Party attitude. Daniel Johnson, then the PLQ leader, was afraid to call himself Canadian. Once it is passed, this resolution will have an impact on how legislation is passed in the House of Commons. It's remarkable how much one could get through that clause if the courts say, well, yes, in some circumstances, it can override certain dispositions of the Charter of Rights.
