Parliamentary Voting System and Constituencies Bill

My Lords, I had not intended to speak on this because, as the noble Lord, Lord Williamson, said, it appeared on the face of it that this was not about thresholds precisely, but a different issue. But the noble Lord, Lord Elystan-Morgan, has demonstrated the connection between the amendment moved by the noble Baroness and the issue of thresholds. Because I spoke last week, I certainly will not go over the arguments, but I want to comment on two points made by my noble friend Lord Strathclyde in reply to that debate. He argued that if you have a threshold relating to turnout, that just encourages people to abstain. He repeated the argument several times, saying that people will think that all they need to do is to abstain and the referendum will be rejected, but my noble friend Lord Lawson pointed out that that is not necessarily how it would go. It might well go in the other direction. He pointed out that, for example, there would be people who were against change but who believed that the threshold will be met and therefore will have an added inducement to vote. That is one category of people who would have an inducement to vote. Secondly, there could be a group of people who are in favour but know that if they do not vote, they may lose the issue. So it can work in several ways. I made the point that in 1979, when we did have a threshold, the turnout then was 63 per cent—very high, even though there was a threshold—and that when the subsequent referendum was held without a threshold, the turnout was actually lower at 60 per cent. So in the particular case of the referendums in Scotland, when we did have thresholds, the turnout was higher. The noble Lord may say that that was an outcome threshold not a turnout threshold—and that is true—but I would argue that the effects of the threshold there are also ambiguous. If the noble Lord thinks that an outcome threshold that is something like the Cunningham amendment, with 40 per cent of the electorate required to vote yes, would encourage a high turnout, why do we not have that kind of threshold rather than a turnout threshold? The argument that a threshold encourages abstention is not very persuasive. The second point made by the noble Lord in reply to the noble and learned Lord, Lord Falconer, was that the Labour Government had been elected by only 21.6 per cent in 2005. If that did for them and the noble and learned Lord was happy with that, why was he not happy with 21.5 per cent in a referendum? A referendum is different from a general election. In a general election, Members of Parliament are up for election and may be up for re-election; a constitutional change is likely to be permanent and difficult to reverse. Secondly, even with 21.6 per cent in 2005, the turnout threshold put forward in the amendments would have been met anyway. There is obviously a difference between 21.6 per cent when at least three parties, and possibly four or five, are standing, and 21.6 per cent in relation to a yes/no proposition. Neither of the arguments the noble Lord puts forward against thresholds is persuasive. I do not know whether or not we will have to vote on this but, on the point made by the noble Lord, Lord Elystan-Morgan, to the noble Lord, Lord Roberts, that we did not have thresholds in previous referenda, although we did have one in relation to the Scottish referendum, one cannot think of a country in Europe that does not have a qualified majority provision for changes in the constitution. I shall be interested in what my noble friend says in reply to these points.
