My Lords, it is always a pleasure to follow the noble Baroness, Lady Jones of Moulsecoomb, although I cannot accept her diagnosis
of this being an attack on democracy. I shall make just three short points, because we do not want this to go on all day.
First, noble Lords who have brought forward these amendments have not adduced any evidence as to why they are needed. The core procedures for the handling of treaties have served this country well. The Ponsonby rule, which the noble Lord, Lord Purvis of Tweed, reminded us of again today, is now enshrined in CRaG. As I said, no practical issues have been put forward for these amendments being needed. The Government have responded to the desire, as expressed by both Houses of Parliament, for more information and more involvement in the processes of scrutiny of trade treaties, most recently in the latest Ministerial Written Statement. I think that I am the only noble Lord speaking here today who has not seen a copy of that Statement but I am sure that it is splendid.
My second point is on the royal prerogative and prerogative power. I agree with my noble friend Lord Lansley that, despite Amendment 6 saying that it does not seek to override or diminish prerogative power, its effect is that, in practical terms, it does so—in particular, in relation to the approval of the negotiating objectives, which is not part of our current processes—and could easily restrict the prerogative power available to government. That is why I think that the Constitution Committee of your Lordships’ House did not recommend that we go down that route.
My third point is on parliamentary accountability. Both amendments in this group are predicated on a view that parliamentary accountability requires legislation to make it effective. That is plainly not in accord with our parliamentary history. It is also, I submit, a dangerous route to go down. The strength of the UK’s parliamentary system is its capacity to evolve constantly, as we have seen in relation to free trade agreements with the way in which the Government have been open to involving Parliament increasingly and in different ways, including through engagement with committees.
If we wrote too much into legislation, that could work against the flexibility that is the hallmark of our system and has served us well, in particular over the last couple of years. I believe that that could end up being Parliament’s loss at the end of the day. The noble and learned Lord, Lord Goldsmith, referred to the constructive partnership that has been emerging between his committee on treaties and the Government, and the practical ways in which the work of his excellent committee is being helped to be effective. I have to say to noble Lords that the more you codify, the more it is less likely that constructive partnership becomes the hallmark of an ongoing approach. Noble Lords really cannot have it both ways.
