The noble and learned Baroness makes a very strong case and I give her my full support.
My name is on Amendments 80 and 91 in this group. Amendment 91 is concerned with victims of human trafficking, but both fall at the hurdle of retrospection, as has been explained by the other signatories, in
particular, my noble friend Lord Carlile, and by the noble Baronesses, Lady Chakrabarti and Lady Hamwee. I have the luxury of being able to add virtually nothing to the arguments already made.
I think the best description of the case against retrospection is in my noble and learned friend Lord Hope’s explanation of Amendment 39, which
“seeks to give effect to the principle that, unless for good reason, legislation should operate prospectively and not retrospectively”.
What is the conceivable good reason? What are the very exceptional circumstances that the Constitution Committee suggested might excuse retrospection?
The noble Baroness, Lady Hamwee, suggested that the Minister might try to say that stopping the boats is so exceptional as to justify retrospection. But there are a lot of other ways of dealing with that; for example, the safe passage visa argued for at Amendment 130. The Minister might say that that it is the cost of housing those who have come across the channel or in the back of a lorry and have been apprehended. But the costs of detaining and deporting those declared inadmissible under this Bill will be much higher.
That is the point the Refugee Council made in its impact assessment and estimate of the costs. It estimated a cost of £9 billion over the first three years. The Minister says that he does not recognise those numbers. That is not a sufficient argument. He needs to tell us what is wrong with those numbers and what his numbers are. It is not good enough just to sit there and say, “Well, I’m not going to engage in this debate because I don’t recognise the numbers”. I think retrospection is fundamentally unacceptable.
A few years ago, when I was driving up Headington Hill in Oxford, I forgot that, eccentrically, the set speed limit there is 20 miles per hour. I was required to present myself in Milton Keynes four months later for a speed awareness course, because I had been travelling at 27 miles per hour. Eccentrically, because I am a very eccentric person, I failed to ask my wife to see whether I could have a personal course. Nevertheless, I would have been very taken aback if, when I got to Milton Keynes—it was extremely hard to find the place and I was driving rather fast trying to find it—I had been told on arrival, “Actually, we have changed the penalty and we are going to export you to Rwanda”. I would have objected, and I object to retrospection.
