My Lords, I am pleased to be able—I use that term advisedly—to respond to the issues raised in the context of these amendments. Given the scope of the contributions, I will perhaps begin by touching on one or two points that have been made by noble Lords in the debate.
The noble Lord, Lord Foulkes, referred to the content of the joint report and quoted, among other things, the phrase,
“the Agreement should also establish”.
The noble and learned Lord, Lord Wallace of Tankerness, did likewise, and referred to the passage about the bestowal of rights that will come with the conclusion of the withdrawal agreement. The noble Lord, Lord Haskel, referred to Michel Barnier’s recent draft—quite accurately, if I may say so. The noble Baroness, Lady Ludford, pointed out that the European Parliament will have to agree to the terms of any withdrawal agreement. That is self-evident.
In other words, these matters are prospective. Why are they prospective? I do not want to be overly technical, and I do not believe that I will be, but we begin with the duality principle of our law. That means that we enter into international obligations at the level of international law and they have no direct impact on our domestic law. For example, the withdrawal agreement will be an international treaty entered into by the Executive. We then implement or bring the rights and obligations of that international treaty into domestic law by way of domestic legislation of this Parliament. That is the duality principle: you have international law and you have domestic law, and you can only have the domestic law once you have the international treaty, because it is from the international treaty rights and obligations that you allow the domestic
rights and obligations to be brought into our domestic law. What we have at the present time is a joint report from December of last year. We acknowledge that.
