My Lords, I too believe that the Government have made the right choice in going to 75 in one go, as my noble and learned friend Lord Etherton put it. We have to bear in mind that what is being suggested is a maximum; I think my noble and learned friend Lord Brown was making that point in passing in what he was saying a moment or two ago.
I am not sure that the examples that my noble and learned friend Lord Etherton gave of people going on until 70 is a very sound guide as to how people will behave if the age is raised to 75, for the very particular reason that a factor that someone has to bear in mind in choosing the age of retirement is whether he has served long enough to earn the full judicial pension. In my day, you had to serve for 15 years; now, you have to serve for 20. For those who have gone on to the Bench in their early 50s, the age of 70 does not give them long enough. When they reach the time when they have achieved that, they may well take the decision to go then, rather than going on for the extra few years, because they have actually earned their full pension. So we are, to a degree, in an area of speculation. We are having to consider human behaviour and how people will behave in view of the two choices of age that we are being given.
We are also contemplating human behaviour in the problem of diversity. I pay tribute to what my noble and learned friend Lord Etherton was saying about the need to increase diversity at all levels on the Bench. I had the responsibility for a while, as Deputy President of the Supreme Court, of being on a commission considering applicants for the position of justice. One of the issues that concerned us at the time was the lack of diversity in the applicants coming before us—a point that I think has been hinted at by my noble and learned friend Lord Brown of Eaton-under-Heywood. Again, we are trying to speculate about human behaviour. There is an immense amount to be said for the diversity element, but I do not think one can be sure that choosing 75 instead of 72 is going to be as damaging as has been suggested.
As for the in-one-go point, I think my noble and learned friend Lord Etherton was referring to me when he mentioned someone who said at Second Reading that the opportunity to legislate on this issue comes quite seldom. I would be concerned, if we were to settle on 72 this time, as to when one would ever get back to the age of 75. As it happens, the Bill has enormous importance behind it because of the need to deal with pensions, which is a pressing issue. It has been possible to bring in the retirement age element and other parts of the Bill because the Bill is already there and the issue fits quite neatly with its broad aim and subject matter. How soon could we be sure that we could ever get back to this issue? For that reason too, the in-one-go point has a lot to commend it.
There is even more to be said for the points made by my noble and learned friends and the point that we are dealing here with an element of speculation, since we are setting a maximum age, not a compulsory one, and it will have the benefits that have been referred to. I believe the Government have made absolutely the right choice here.
