Mixed messages in bottles: the European Union, devolution, and the future of the constitution

摘要

An unprecedented eleven-member UK Supreme Court decided R (Miller) v Secretary of State for Exiting the European Union on 24 January 2017. The Government’s argument, that it could start the process of withdrawing from the EU using a prerogative power instead of an Act of Parliament, was comprehensively defeated by an 8:3 majority. However, the Government also secured a unanimous verdict that it did not need the consent from the devolved legislatures in Scotland, Wales, and Northern Ireland before invoking Article 50 of the TEU. I explore the judicial argumentation in light of Philip Bobbitt’s six modalities of constitutional argument, five of which feature, and one of which ought to have featured, in this seminal case.
