'Professor Goldsworthy's thoughts on sovereignty are always challenging and important, often combative, and rarely easy to dismiss. It is extremely useful for those interested in the area to have his views in one volume … There is a great deal to be admired in Parliamentary Sovereignty … [which] is another important contribution by … Goldsworthy to a topic which is returning to the front line of constitutional debate … [He] is deservedly one of the most well known of those representing a coherent, historical and democracy-based argument for parliamentary sovereignty in its classical form. His new book is an important contribution to an important contemporary debate. It presents a real and continuing challenge to the idea that common law constitutionalism is the new orthodoxy, and for that both supporters and opponents should be grateful.' C. J. S. Knight, Law Quarterly Review
