No, the provisions are not required for the reasons that the noble Lord has suggested but because we believe they are necessary for the current institutions and in the light of the NAO report, which was written before these new providers came on to the scene. The department has no right of access to the providers. This affects the extent to which it can investigate currently rather than in future.
I turn to my noble and learned friend. I am not sure that I can usefully add to what I said earlier. I would not of course challenge for a moment what he said about practice in the judiciary. My understanding is that it is not usual practice within powers of entry provision for the magistrate to sign a certification document, and we are still unaware of any examples of this. The relevant clause in the Bill, as I think I said a moment ago, sets out the considerations that magistrates would have to take into account when making their judicial decision to grant a warrant, and we have full confidence that this constitutes a sufficient safeguard to ensure that a warrant will be granted only where necessary. For that reason, we are not persuaded that his amendment, in saying that it would have to be signed, constitutes an extra safeguard to ensure that a warrant would be granted only where necessary. I hope that, against that background, my noble and learned friend will feel that he does not have to press his amendment.
