The European Union Act 2011 (EUA) is an unprecedented constitutional experiment. This post will outline the two main innovations of the Act: (1) the section 18 ‘sovereignty’ clause; and (2) the scheme of ‘referendum locks’ introduced in sections 2, 3 and 6. Three key questions raised by the EUA for UK constitutional lawyers will then be identified, and some tentative responses to these questions sketched. The post draws on an article written in collaboration with my colleague Michael Dougan, which is to be published in the February 2012 edition of the European Law Review.
