My Lords, I think that there has been some discussion about this. The situation is that the EU is in charge of the treaty. Therefore, if we are not out of the treaty, we remain members as a result of the treaty of the European Union. However, the treaty by itself was not the whole story, because we had to pass an Act of Parliament to make the treaty work in the United Kingdom. If, as has happened, the EU has extended the date so far as the treaty is concerned, in order to make our law conform with the way the treaty works, the statutory instrument is required. Otherwise, there would be a discontinuity between the treaty on the one hand and the initial law on the other.
