The consent of the governed is a value that is basic to our understanding of a free and democratic society. Yet democracy in any real sense of the word cannot exist without the rule of law. It is the law that creates the framework within which the "sovereign will" is to be ascertained and implemented. To be accorded legitimacy, democratic institutions must rest, ultimately, on a legal foundation. That is, they must allow for the participation of, and accountability to, the people, through public institutions created under the Constitution. Equally, however, a system of government cannot survive through adherence to the law alone. A political system must also possess legitimacy, and in our political culture, that requires an interaction between the rule of law and the democratic principle. The system must be capable of reflecting the aspirations of the people.
The argument that the Constitution may be legitimately circumvented by resort to a majority vote in a province-wide referendum is superficially persuasive, in large measure because it seems to appeal to some of the same principles that underlie the legitimacy of the Constitution itself, namely, democracy and self-government. In short, it is suggested that as the notion of popular sovereignty underlies the legitimacy of our existing constitutional arrangements, so the same popular sovereignty that originally led to the present Constitution must (it is argued) also permit "the people" in their exercise of popular sovereignty to secede by majority vote alone. However, closer analysis reveals that this argument is unsound, because it misunderstands the meaning of popular sovereignty and the essence of a constitutional democracy.
Canadians have never accepted that ours is a system of simple majority rule. ...By requiring broad support in the form of an "enhanced majority" to achieve constitutional change, the Constitution ensures that minority interests must be addressed before proposed changes which would affect them may be enacted.
Accordingly, the secession of Quebec from Canada cannot be accomplished by the National Assembly, the legislature or government of Quebec unilaterally, that is to say, without principled negotiations, and be considered a lawful act. Any attempt to effect the secession of a province from Canada must be undertaken pursuant to the Constitution of Canada, or else violate the Canadian legal order.
Quebec could not, despite a clear referendum result, purport to invoke a right of self-determination to dictate the terms of a proposed secession to the other parties to the federation. The democratic vote, by however strong a majority, would have no legal effect on its own and could not push aside the principles of federalism and the rule of law, the rights of individuals and minorities, or the operation of democracy in the other provinces or in Canada as a whole. Democratic rights under the Constitution cannot be divorced from constitutional obligations. Nor, however, can the reverse proposition be accepted. The continued existence and operation of the Canadian constitutional order could not be indifferent to a clear expression of a clear majority of Quebecers that they no longer wish to remain in Canada. The other provinces and the federal government would have no basis to deny the right of the government of Quebec to pursue secession, should a clear majority of the people of Quebec choose that goal, so long as in doing so, Quebec respects the rights of others. The negotiations that followed such a vote would address the potential act of secession as well as its possible terms should in fact secession proceed.
The obligations we have identified are binding obligations under the Constitution of Canada. However, it will be for the political actors to determine what constitutes "a clear majority on a clear question" in the circumstances under which a future referendum vote may be taken. Equally, in the event of demonstrated majority support for Quebec secession, the content and process of the negotiations will be for the political actors to settle.
We have also considered whether a positive legal entitlement to secession exists under international law in the factual circumstances contemplated by Question 1, i.e., a clear democratic expression of support on a clear question for Quebec secession. Some of those who supported an affirmative answer to this question did so on the basis of the recognized right to self-determination that belongs to all "peoples". Although much of the Quebec population certainly shares many of the characteristics of a people, it is not necessary to decide the "people" issue because, whatever may be the correct determination of this issue in the context of Quebec, a right to secession only arises under the principle of self-determination of peoples at international law where "a people" is governed as part of a colonial empire; where "a people" is subject to alien subjugation, domination or exploitation; and possibly where "a people" is denied any meaningful exercise of its right to self-determination within the state of which it forms a part. In other circumstances, peoples are expected to achieve self-determination within the framework of their existing state. A state whose government represents the whole of the people or peoples resident within its territory, on a basis of equality and without discrimination, and respects the principles of self-determination in its internal arrangements, is entitled to maintain its territorial integrity under international law and to have that territorial integrity recognized by other states. Quebec does not meet the threshold of a colonial people or an oppressed people, nor can it be suggested that Quebecers have been denied meaningful access to government to pursue their political, economic, cultural and social development. In the circumstances, the National Assembly, the legislature or the government of Quebec do not enjoy a right at international law to effect the secession of Quebec from Canada unilaterally.

Although there is no right, under the Constitution or at international law, to unilateral secession, that is secession without negotiation on the basis just discussed, this does not rule out the possibility of an unconstitutional declaration of secession leading to a de facto secession. The ultimate success of such a secession would be dependent on recognition by the international community, which is likely to consider the legality and legitimacy of secession having regard to, amongst other facts, the conduct of Quebec and Canada, in determining whether to grant or withhold recognition. Such recognition, even if granted, would not, however, provide any retroactive justification for the act of secession, either under the Constitution of Canada or at international law.
