My Lords, I will briefly set out why I do not think this is a particularly helpful Amendment, which I am sure the noble Baroness is not entirely surprised to hear. Despite what she said, I am not sure the amendment is entirely intended to be helpful.

This is an area in which there is a balance to strike. The noble Baroness is quite right that the Illegal Migration Act shifted the balance—a little—in favour of the Home Secretary; the balance had drifted too far in the other direction. I strongly support the need for some limits and constraint on the ability of the Home Secretary to use detention powers, but if you are not careful, those who try to frustrate the system inappropriately—people who have no right to be here—will use the rules to frustrate an attempt legitimately to remove them from the country.

I saw many cases of people who had no right to be in the United Kingdom, and who had failed on a number of occasions to stay here through the legal processes, using this as another tool. If you have strict, bright-line rules, the danger is that people game and frustrate the system. The Home Secretary does not want to detain more people than is absolutely necessary; there is a very significant cost in doing so. As she well knows, the Home Office does not have an unlimited budget, but it is necessary to have these powers.

Certainly, the powers that were in place before the provision the noble Baroness, Lady Jones, is trying to repeal needed strengthening. As I said, this moves things in the direction of the Home Secretary, but as with all the Home Secretary’s powers, she has to exercise them in a reasonable and lawful manner, and all the decisions she takes are challengeable by judicial review.

The Illegal Migration Act still refers to whether the detention is “reasonably necessary”. It still has that test, so the Home Secretary has to exercise that judgment. If somebody feels that the Home Secretary has got that judgment wrong, it is still open to them to challenge it. However, I agree with the noble Baroness, Lady Jones, that the balance has shifted in favour of the Home Secretary.

I come back to what I said in the earlier group: there is a balance to strike here. Much of the debate so far is coming from one particular angle. I do not criticise the noble Baroness for doing it, but the other side of the argument needs to be put, so the House can hear a more balanced argument. We need a firm system which allows people to come to and stay in the United Kingdom if they are following our rules or have a legitimate asylum claim; equally importantly, where they do not, they should not be able to use rules and regulations that are there to protect people, in order to frustrate the legitimate exercise of that power.

To all those who want an asylum system, or one that allows people to come here legitimately, I urge them to be careful what they wish for, because we are getting to the point where the public are losing patience. Ministers are ultimately accountable both to the House of Commons and to the House of Lords, but if the public do not feel that Ministers are accountable, or if they feel that they do not have the powers to deliver a system the public want to see, public belief and confidence in the system will disappear, and that would be very dangerous. Those who want a more liberal system would rue the day that that happened.

Therefore, having that balance is necessary. The changes made in the Illegal Migration Act to the powers on detention moved in the right direction. The fact that the Government, despite doing a pretty wholesale removal of the powers in that Act, have not removed this one suggests that Ministers think that shift in the balance was sensible. I therefore hope that it remains in place. Regretfully, if the noble Baroness presses her amendment to a vote, I will not be able to support it. I hope she understands why, and I suspect it will not be a surprise to her to learn that I am unable to support it.
