Before the noble Earl sits down, I would like to pick up the point that was made to him at lunch. He will be aware that when the Scottish Parliament was established, a great deal of store was set by the form of the committee system, which it was hoped would be independent and would provide the kind of scrutiny that a second Chamber would afford. I do not think it is challengeable that the committee system has unfortunately become very political, to the extent that it is very difficult for Members on the committee to strike the kind of independence that we sometimes see in Select Committees in the other place and here. A consequence is that an effort to introduce a principle of “holding to account” has not been maintained in the way that it was in the beginning. If that continues, it makes the case for a second revising opportunity—I do not describe it as a Chamber—overwhelming.

I shall speak briefly to the amendment proposed by the noble and learned Lord, Lord Mackay of Clashfern. I do not do so because I once enjoyed the privilege of being one of his deputes when he was Lord Advocate for Scotland—as did the noble and learned Lords, Lord Hope and Lord Cullen, both of whom are in their places this evening. I do so without detracting in any way from the amendment in the name of my noble and learned friend Lord Wallace of Tankerness. What attracts me to the amendment proposed by the noble and learned Lord, Lord Mackay, is its simplicity and practicality. It is easily understood, and coming, as it were, from a Scottish source, it pays due regard to economy. For those reasons it is well worthy of consideration. Its simplicity makes it easily capable of being understood not just by those who will have responsibilities under it, but by members of the public.

It is for those reasons that I am, with due deference, rather doubtful about the amendment tabled by the noble Lord, Lord Wigley. The problem with it is that, apart from the reference to the Supreme Court turning into some kind of court of arbitration, and I know of no process or procedure that would allow for that—

It is a question of judgment. The mechanism that the noble Lord suggests may achieve the objectives that he sets out, but it will almost certainly encourage delay, and perhaps even more controversy. What is required here is very quick resolution, in an uncontroversial way, of issues that lie at the very heart of the economies, perhaps, of the United Kingdom—and those of Scotland, Wales and Northern Ireland. It seems to me that the noble and learned Lord, Lord Mackay, has pretty well hit the target.

The noble and learned Lord’s intervention is most helpful. Of course, the language of proposed subsection (17), in Amendment 318AA,

“refer any question to the Supreme Court”,

supports the view that the use of the Supreme Court in such circumstances would be, to put it mildly, doubtful.

My difficulty with the proposal of the noble Lord, Lord Wigley, is that it is bound to encourage delay. His amendment says:

“The Panel may call witnesses or take legal advice”.

If witnesses are called they may have to be cross-examined, and if there is to be cross-examination there may have to be representation by counsel, or something of that kind. It is not difficult to imagine what is proposed in the amendment turning into something of a full-blown hearing, rather like, for example, industrial tribunals.

Under suggested subsection (15)(a), regard must be had to whether something,

“is reasonable, in all the circumstances”.

As soon as the concept of reasonableness appears in a statute, it opens up the possibility of judicial review. Even if it were not to be granted, none the less an application for judicial review could obviously, and unfortunately, delay the outcome of a decision that might be of considerable economic as well as political importance. For those reasons, however well intentioned the noble Lord’s proposal is, I do not think it stands any proper comparison with that of the noble and learned Lord, Lord Mackay. I therefore urge the Government to give serious consideration to that, for the reasons the noble and learned Lord set out, which I have tried to follow.
