We, the undersigned, Thomas M. Franck, Becker Professor, School of Law, Director, Center for International Studies, New York University, Rosalyn Higgins, Q.C., Professor, London School of Economics, member of the Human Rights Commission, Alain Pellet, Professor of Public Law at the University of Paris X - Nanterre and at the Paris Institut d'Études politiques, member of the International Law Commission of the United Nations, Malcolm N. Shaw, Professor, Faculty of Law, University of Leicester, and Christian Tomuschat, Professor, Institut für Völkerrecht, Bonn University, President of the International Law Commission of the United Nations, having been consulted by the Committee to examine matters relating to the accession of Québec to sovereignty on various legal questions relating to the territorial integrity of Quebec in the event of the attainment of sovereignty, do hereby render the following opinion:
Question No. 1
If Quebec were to attain independence, the borders of a sovereign Quebec would be its present boundaries and would include the territories attributed to Quebec by the federal legislation of 1898 and 1912, unless otherwise agreed to by the province before independence, or as between the two States thereafter.
Question No. 2
If Quebec were to attain independence, the principle of legal continuity (absence of a vacuum juris) would allow the territorial integrity of Quebec, guaranteed both by Canadian constitutional law and public international law, to be asserted over any claims aimed at dismembering the territory of Quebec, whether they stem from:
the Natives of Quebec, who enjoy all the rights belonging to minorities, in addition to those recognized in indigenous peoples by present-day international law, but without giving rise to the right to secede;
the anglophone minority for whom the protection provided by international law has no territorial effect; or
persons residing in certain border regions of Quebec, who, as such, enjoy no particular protection under international law. These conclusions are reinforced by the applicability of the principle of the succession to the existing territorial limits at the time of independence.
