My Lords, I hope I will be allowed a moment when referring to my Motion B1 and Amendment 22R on page 5 of the Marshalled List to pay a very short tribute to the staff of the Public Bill Office. I was treated very kindly by a very tolerant member of staff there when I was being completely dysfunctional late last night and early this morning. They have been put under enormous pressure, and I think we should appreciate that. It may have felt to them like bullying, I am afraid.

I do not know why we have been forced to consider these amendments today, or indeed before the Summer Recess. The very earliest this Bill could ever be used would be after the Supreme Court decision in October, or whenever that is given; we do not know the exact date. Indeed, that may not be the end of the litigation in any event. I do not understand why we were not left to consider this in the sittings in September. I hope we will not be put in this position again.

I now turn to my Motion. This is where I express my genuine gratitude to the Government—to the Minister and others, including the Chief Whip—because they have made, in my view, a correct and noble concession to the objections that this House voted for in an amendment I moved on retrospectivity, pointing out as I did at the time that retrospectivity, though not a “never”, is frowned on in our law.

My Motion on page 5 of the Marshalled List—which I will not test the opinion of the House on tonight—mitigates the rigour of the exception that has been created in the Government’s amendments. They say they have abandoned retrospectivity, to put it crudely, but they have retained a regulatory power to abandon retrospectivity. I am not going to force the issue tonight, but I ask the Government to reflect on the constitutionality of that approach, because it makes me feel decidedly uncomfortable. I do not want to dilute my thanks for the acceptance in principle of what I moved a few days ago.
