My Lords, I shall speak to Amendment 11, a wide-ranging amendment, and make some general comments arising from it. I am particularly concerned about the relationship between leaving the single market—going it alone—and international law, because in various permutations there are a number of aspects that impact on a whole range of things here in this country and more widely, as quite a number of speakers have already pointed out this afternoon.
In particular, I would like to know how the Government would react to an international commitment, hitherto embedded in EU law but also part of international law, which they disliked. As we know from wider political debate over recent weeks, adherence to the rule of law is important—to Parliament, to the public and to the Government. On the other hand, one of the curious consequences of exercising sovereignty in its rawest form is that you are able to overrule the rule of law, whatever you might have signed up to previously.
Clearly, international law has a different impact at home and abroad, but the old, clear line of demarcation between home and abroad, and the relationship between the role of Parliament and the exercise of the prerogative
is, I believe, mere fancy, as has been mentioned by a number of speakers. Decisions taken abroad, outside the jurisdiction, may not be directly enforceable in the courts at home, but they define a Government’s standing and credibility and, if implemented, can have a far greater impact on the UK than much domestic legislation.
For all this, I believe that the Committee is fully entitled to a cogent, understandable and comprehensive description of the Government’s approach to these matters, and that it should be given from the Dispatch Box to ensure the whole story—a kind of Pepper v Hart process. How this question is answered may very well determine how my votes are cast if and when amendments to the Bill are pressed: and I dare say that the same may be true for others.
