European Union Bill

That is an interesting point. The Prime Minister, rightly or wrongly, certainly believes that it is in Britain's national interest to adopt from time to time measures that he perceives to be in Britain's national interest and then to encourage Parliament to follow suit. We have to decide whether that is the case—but that is another debate. The debate has brought to the fore a number of important issues. I am thinking in particular of the extremely important argument made in the European Scrutiny Committee's report on the true nature of the threat to parliamentary sovereignty. The objective evidence presented by the Committee to the House leads it to conclude that"““if the legitimate supremacy of Parliament is under threat, it is from judicial opinions in other areas of law””," not EU law. That is true. I am thinking in particular of the Jackson case of 2004, which concerned the constitutional validity of the Hunting Act 2004, and in which three Law Lords indicated that in certain circumstances the courts had inherent powers to disapply legislation. I am worried that the Government do not appear to recognise that there is a real debate taking place on this issue between those who argue that the absolute supremacy of Parliament remains unqualified—as explained by Dicey, the British constitutional scholar—and those who believe that sovereignty of Parliament is a construct of common law. According to those who hold this view, the sovereignty of Parliament is open to revision by the courts. In the Bill's explanatory notes, the notion of parliamentary sovereignty as a construct of common law is expressed as though it were a matter of fact and entirely uncontroversial. Similarly, a one-page note on the Bill produced by the Foreign and Commonwealth Office states:"““there is a common law principle that the UK Parliament is sovereign””." It is dangerous to view the legislative supremacy of Parliament as an offshoot of common law, because it means that the principle will vary according to the judicial whims of judges at any given time.
