This article argues that parliamentary sovereignty’s assimilation of constituent power—the ultimate power in a legal order to create and posit a constitution—has stultified the development of British constitutional law. The result is a deeply ideological, as distinct from oft-heralded pragmatic, constitutional structure that is incapable of confronting the systemic challenges the United Kingdom currently faces. By conceptualizing a more antagonistic relation between the Crown in Parliament and “the people” by questioning the democratic credentials of the former, this article contends that the UK constitutional order can be reinvigorated. [---]
