My Lords, this area of the definition of liberty is, and always has been, extremely difficult. The Strasbourg court has wrestled with it. It is absolutely vital from the legal point of view—I understand the distinction that has been made and I will mention that again—that this definition should be in accord with the convention; otherwise, we will have trouble maintaining this in the face of challenge. It is difficult to say that the Government’s definition is not in accordance with the convention. It seems clear that it is so. Therefore, all the decisions taken here and in Strasbourg in respect of it are available to help in the formulation of guidance.
If a different definition is taken which does not expressly subscribe to the convention, there is certainly room to try to squash definitions or applications which are in line with this definition as amended by the noble Baroness. It is perfectly open to use the legal definition in the main, in accordance with the convention, and then to help people as best we can to understand what it is all about by giving guidance, which is not authoritative in the same way as judicial decisions. There is quite a lot of scope for trying to do that with guidance which will be in accordance with what the practitioners have asked for. I should say that I am an honorary vice-president of the Carers Trust, but that does not affect what I have to say about it. I can see the need to help people in the actual work they have to do; this is a legal definition, and not all legal definitions are absolutely self-apparent to people who are not lawyers. But the guidance provided for can help in that respect, and there is a serious risk that, if we do not do something of that kind, the result will be litigation which could affect the viability of this clause in the future.
