My Lords, I, too, strongly support this amendment. If I have a quarrel with it, it is that I do not think it goes far enough. If I have read the amendment correctly, it focuses simply on the provisions of the Bill when it becomes an Act. The focus on the quality and quantity of co-operation that does or does not exist should go beyond just what this Bill is seeking to achieve; its scope should include all the provisions and measures that have led to the devolved constitution we now have.
For a similar reason I wonder why this amendment seeks just a single report on the level of co-operation that is being achieved. That co-operation is such an important continuing ingredient of a successful devolved constitution that it should not simply be subject to a single one-off review and report.
The perspective that I bring to this precedes the wisdom that the Smith commission added in this area and goes back to the Calman commission, of which I was a member. Noble Lords may remember that the longest chapter in the Calman commission report turned out be chapter four. We came up with 25 recommendations under just that chapter, which concerned strengthening co-operation. The evidence that we took on the need for co-operation was compelling. The evidence from other countries with stable and successful devolved constitutions was especially compelling. It was quite clear from that evidence that the ability of different Governments and Parliaments to co-operate and work together in a constructive and structured manner is an absolutely fundamental ingredient of a resilient, flexible and successful devolved constitution. There was nothing ambiguous about the evidence that we took.
We also took evidence on the extent to which people in Scotland and interests in Scotland expected there to be constructive co-operation between the Governments and Parliaments of the United Kingdom and Scotland. They expected it to be a norm, not an exception. However, the depressing conclusion that we came to when we reported was that apart from a few bright spots, good, constructive co-operation between the United Kingdom and Scotland was an exception, not a norm. Therefore, I very much support the direction of travel of this amendment. However, as I said, I would go very much further and widen its scope to include all the measures that comprise the devolved constitution, and I would make it a continuing or regular discipline rather than a one-off one.
