My Lords, in my heart of hearts, I take a harder position than the noble Lords, Lord Williamson and Lord Hurd. I will support their amendment because no amendment on the Order Paper delivers exactly what I want. Referendums should only and always be advisory. The idea of a mandatory referendum is fundamentally destructive to the principles of parliamentary democracy. The noble Lord, Lord Hannay, said that what we have here is a palliative; I would rather have a cure.
First, I would cite the noble Baroness, Lady Thatcher, in support of what I have just said. It was a great pleasure to hear the noble Lord, Lord Hurd, tonight. He and I both experienced how rash it was to disagree with the noble Baroness, Lady Thatcher, so I wish to agree with the view that she expressed in the debate in 1975 on the Referendum Bill that the referendum should only be advisory and that if it were mandatory it would be destructive of parliamentary sovereignty.
An additional argument concerns timing. An advisory referendum, and possibly even a mandatory referendum, would not be quite so objectionable if it preceded the negotiation of the change in the EU texts to which the Government had agreed.
I was very much against the idea of a referendum on the euro in 1994—I do not remember that my opinion was sounded; quite rightly, it was not—but that was not quite as bad as what is foreseen in the Bill. If we were now to decide that we wished to join the euro, that would be followed by a negotiation with our partners that are now in the euro and might or might not result in our joining the euro. The Bill states that at the end of the process in Brussels—when the Government have extracted concessions from others around the table and a consensus has been found, the decision has been brought back and is acceptable to the Government and to Parliament—a referendum should decide whether we renege on what we have done.
The concept of interlocuteurs valables is quite important. When an ambassador is received by the state to which he is accredited, he presents his credentials. When the Foreign Secretary or his side-kick start a negotiation in Brussels, it is accepted that they speak for their Government. It then follows that if they do a deal, their Government will not renege on it. So when in the end a deal a struck—if one is struck—all participants are pledged to deliver it.
I was shocked when the French referendum on the constitutional treaty did not lead to resignations in the French Government. The people who negotiated the text which the French decided to reject should immediately have resigned. However, there may be a difference between a presidential and a parliamentary system of government; a president can stand away from an issue and blame the Government. You cannot do that here. If in a referendum on some arcane issue—which, on the basis of the Bill, might be decided on a very low turnout and a very low majority—we decided that we were going to renege on the deal that had been done and the text that had been initialled in Brussels, I would hope that the Ministers who had initialled the text and those who had negotiated for them would resign. They would have to.
Whether a referendum is mandatory or advisory depends in part on when it is. Here we have the worst case; under this Bill, all referendums will be after the negotiations. They are all linked to treaty changes and to a process that has taken place in Brussels; the outcome is brought back and the decision is taken on whether it should go to a referendum. If the referendum finds against the Government, it should lead to the resignation of the responsible Ministers. In honour, they would have to do that.
The noble Lord, Lord Hannay, earlier quoted tellingly from Jean-Claude Piris’s memorandum to the Commons European Scrutiny Committee about good faith. He spoke about the implications of adding new hurdles to the simplified treaty revision procedure. There is a bigger issue of good faith here. We are going to send our negotiators to negotiate and, when they have completed the job, they will carry on and there will be no change unless the country votes for it. I would much prefer an amendment that makes it purely advisory—a Thatcher amendment. There is no Thatcher amendment on the Order Paper now. I therefore support the amendment proposed by the noble Lords, Lord Hurd and Lord Williamson.
It is a huge delight to find myself in agreement with what the noble Lord, Lord Stoddart, said about Amendment 6; he is completely correct. As to what he said about Amendment 5, the two go together. It is a technical point and I do not think that there is a difference. Amendment 5 is a necessary consequence of Amendment 6, but the noble Lord, Lord Williamson, will correct me if I am wrong.
Amendment 5 would establish an advisory referendum in all cases and not only in the case where there was the 40 per cent threshold. The distinction made by the noble Lord, Lord Stoddart, was quite intelligible and clear. Amendment 6 would establish the advisory nature of the referendum when the turnout was below 40 per cent. The noble Lord, Lord Kerr, will be glad to hear, because he supported Amendment 5 without quite understanding it, that it would establish an advisory referendum in all cases.
I have no more to say except to share the hope of the noble Lord, Lord Hurd, that the Minister, if he grumbles at all, will do so in the most mild and polite form.
