This comprehensive second edition offers an authoritative account of Scotland's constitutional arrangements, thoroughly updated to reflect the seismic shifts in UK constitutional law since the 2014 independence referendum. The book charts the Scotland Act 2016, which gave effect to the cross-party Smith Commission agreement reached following the referendum, alongside the far-reaching consequences of the 2016 EU referendum - a vote whose unexpected outcome did much to reignite the debate over Scotland's constitutional future.
Central to this edition is an in-depth analysis of the Supreme Court jurisprudence which has helped clarify the limits – some of them unexpected - to the Scottish Parliament's legislative competence, including the pivotal question of its inability to legislate for a second independence referendum without the sanction of the UK Parliament. Following the UK's withdrawal from the EU, the standalone European dimension chapter from the first edition has been removed, sharpening the book's focus on the two dimensions that now define Scotland's constitutional framework: the Scottish dimension, which remains the principal focus throughout, and the UK dimension, treated in its traditional place following the Scottish material.
Reflecting the author's commitment to currency and accuracy, publication of this edition was deliberately held back to allow full account to be taken of the outcome of the Scottish Parliament election in May 2026, with the text stating the position as at 1 June 2026. The result is an essential, up-to-the-minute reference for scholars, practitioners, students, and anyone seeking to understand the evolving legal and political architecture of devolved Scotland within the United Kingdom.
