My Lords, my Amendment 318A is in this group. As your Lordships know, I am a lawyer, but I have already got limited support from the noble Lord, Lord Wigley, who has repeatedly explained that he does not suffer from this disadvantage—I will do my best to take him along with me.
As I have indicated, I was first introduced to this matter in a discussion with a very distinguished SNP Member in the other place, when we were travelling together from the north. I mentioned to him that I had had no briefing of any sort from the Scottish Government. The next day I got a message from the Scottish Government to say that the Lord Advocate and Mr Russell, the Minister, were very willing to speak to me. I was able to speak to the Lord Advocate that afternoon and to Mr Russell in the early afternoon that Wednesday. I was very emphatically assured by Mr Russell that the Scottish Government were keen to reach an agreement. I am quite satisfied that there is no indication in the attitude of the Scottish Government that this is an attempt to further their ultimate political aim, and that they are seeking to solve this matter in a way that accords with the dignity of the Scottish Government. I said that I did not want to do or say anything that would impede agreement, and I now hope to show how agreement can be reached.
Before I explain the amendment, I will say a word or two about the law that lies behind it—I will take Scotland as an example, as the other Administrations have similar provisions. The devolution settlement in the Scotland Act is subject to EU law. That considerably restricts what the Scottish Administration can do at present, but when Brexit comes along that limitation will disappear. Included in those limitations are the legislative powers of Brussels to legislate in the United Kingdom. From one point of view, it is wise to analyse these powers in this way: a power that can be made effective within a single area of legislative competence in the United Kingdom should go straight to that level—in other words, to the devolved Administration. That is, if the power does not require more than one of our legislative areas in order to be effective, it should go straight to the devolved Administration.
But there are EU powers which can only be effective when they cover more than one of our legislative areas. The one that is of most relevance in this connection is that which provides for the single market. As your Lordships know, and as the Scottish Government certainly know, the single market is quite an important feature of the present negotiations. Part of that single market is the single market in the United Kingdom. It is 100% obvious that, if you are going to legislate for the single market in the United Kingdom, it is legislation that affects all of the countries within the United Kingdom and the legislatures that support them. Therefore, it is absolutely plain that the ultimate power to settle the single market provisions lies with the United Kingdom Parliament.
But—and this is an important consideration—it is extremely wise to proceed by agreement where it is at all possible. A good deal of agreement has already been reached. As I said, I was assured by Mr Russell when I first spoke to him—and again when he later saw my amendment, which he welcomed subject to qualifications such as the noble Lord, Lord Wigley, will propose—that the Scottish Government are very anxious to reach agreement.
