My Lords, I am tempted to say: “Follow that!” The noble Lord has given us something that is not just elegant and eloquent but very firmly researched. To avoid the risk of being accused of being repetitive or even repetitious, I propose to adopt the contribution not only of the noble Lord, Lord Young, but that of the noble Lord, Lord Cormack, both of which point very firmly in favour of this amendment.
I took some time—but not as much as the noble Lord, Lord Young—to look at the dictionary and examine what the word “practicable” is said to mean. There are a series of alternatives: realistic, feasible, possible. The point about them, however, and the point about practicable, is that these are all subjective. The consequence, as was hinted at just a moment ago by the noble Lord, Lord Young, is that there is a discretion which is virtually unfettered. The potential problem for Governments, of course, would be that a failure would be subject to the possibility of judicial review. Very few Governments would want to be put to the embarrassment of being taken to the High Court to explain their failure to do something which, as the noble Lord, Lord Young, has just pointed out, is routinely a matter of administration.
The point is this: the amendment does not destroy that discretion but limits it so that Governments cannot use it for their own interests. We have had several examples of that, both at Second Reading and again today. It cannot possibly be wrong to allow the Government discretion but to ensure that they do not abuse it.
