8 According to Art. 50(2) TEU, the withdrawal agreement shall be concluded ‘on behalf of the Union by the Council, acting by a qualified majority, after obtaining the consent of the European Parliament’.

11 See, most famously, Supreme Court of Canada 20 August 1998, 2 S.C.R. Reference re Secession of Quebec, p. 217 at p. 220 (holding that right of each participant in federation to initiate constitutional change implies duty on other participants to ‘engage in discussions to address any legitimate initiative’ on secession).

13 See Art. 4(2) TEU. On a comparative note, in the United States, the secession of states from the union is generally considered contrary to the US Constitution, while the (un)constitutionality of forming new states within existing states seems less clear. See, on secession of states, US Supreme Court 12 April 1869, 74 U.S., Texas v White, p. 700 at p. 725 (‘The Constitution, in all its provisions, looks to an indestructible Union, composed of indestructible states’). The Alaskan Supreme Court has even gone so far as to consider on this basis that states are precluded from holding a referendum on secession. See Supreme Court of Alaska 17 November 2006, 147 P. 3d, Kohlhaas v Alaska, p. 714. On the partitioning of existing states, see US Constitution, Art. IV, Sec. 3. The proper construction of this provision appears to elude consensus, see Kesavan, V. and Paulsen, M. Stokes, ‘Is West Virginia Unconstitutional?’, 90 California Law Review (2002) p. 291CrossRefGoogle Scholar, at p. 332 ff.
