I am afraid not, as I really must proceed.
None of these judge-made principles had any basis in the EU treaties, and the principle of the primacy of EU law is a judicial creation recently codified, and no more than that. However, because we have accepted judgments of the European Court under section 3 of the European Communities Act 1972, which we are going to repeal, we are saddled with this, and that is one of the things we are going to unshackle.
Interpretation is done in the European Court by what is known as the purposive approach. In fact, as has been well said, there are many different purposes that can be in conflict with one another, and the methods of interpretation applied are anything but satisfactory. I therefore say to those who want to advocate the European Court, whether in the transitional period or in general, “Beware of what you wish for,” because the European Court can create havoc in relation to our trading arrangements.
