My Lords, it is a great privilege to follow the noble Lord, Lord Blunkett, who has brought to bear his own experience on this issue. I would like very briefly to speak in favour of all these amendments. In essence, there are five main proposals before the House, some with variance. They are as follows: first, leave it as it is and rely on the discretion of the prosecutor; secondly, have authorisation in all cases either by the secret services or by the Competition and Markets Authority, or any of the authorities, and, in due course, review by the Investigatory Powers Commissioner; thirdly, pre-authorisation either by a judge or by the Investigatory Powers Commissioner or a Secretary of State; fourthly, pre-authorisation, except in an emergency, by the same people; and, fifthly, real-time notification.
I agree with the noble Lord, Lord Blunkett, about the comment made last week by the noble Lord, Lord Cormack—who spoke very wisely, as he often does, in saying that we should attempt to find the best solution. The difficulty is knowing how to do that without evidence as to the pros and cons. None of this is easy and getting it wrong will be very damaging to all concerned. Perhaps I may illustrate that by taking one of the alternatives and saying what it would be helpful to know. I shall take the example of real-time notification.
The first question I would like answered is: if the authorities can tell the Investigatory Powers Commissioner within seven days, why is it not possible in most cases to notify in advance? It would certainly be far safer to do that. Secondly, if this course is adopted, will each change have to be notified? Thirdly—this is the most serious question—what will happen if the Investigatory Powers Commissioner says that the authority should not have been granted? Will the authorisation cease immediately; and if it did not, what would the consequences be under the Human Rights Act, for example, for those affected? Presumably, any disallowance or contrary views by the IPC would not be retrospective. Fourthly, would not the report at the end of the year identifying that authority should not have been granted be more damaging than trying to stop that mistake in the first place by pre-authorisation?
Should this real-time notification apply to everyone? Like the noble Lord, Lord Naseby, and many others who have spoken, I have the greatest admiration for the security and secret services. But is the same true of the Competition and Markets Authority and the Food Standards Agency? We have to be careful of what can happen on people’s coat-tails.
Finally, I really do think it would be useful to have the views of the Investigatory Powers Commissioner himself on this idea. He has to operate it; does he think it practicable, and what is to happen?
I could, drawing on my own experience, try to give some more details in respect of these matters, but I fear that in doing so I might be at risk of transgressing, as would other noble Lords, by inadvertently saying something very sensitive. That is why in our previous sitting, in the debate on the second group of amendments, I suggested finding a means of ensuring that there is
evidence before the House to enable it to understand the deficiencies in the present law which need to be corrected, and to scrutinise the proposals for reform and try to ensure that the proposals, if necessary as amended, will work well for the future. My general experience has been, in relation to both the police and the security services, that they are rightly reticent about putting matters into the public domain. But it is often possible to put sufficient into the public domain without damage to security and methods of operation. However, you cannot do that unless you know enough about the issues and the evidence.
It is also my experience that subjecting issues of this kind to independent scrutiny and not relying on conclusions that are put forward is in the overwhelming interest of the security services, the police and the other bodies. That is because these are difficult issues of judgment that need to be scrutinised externally and independently and then addressed so that the risk of future errors is minimised and confidence maintained. That is why I would hope that means can be found to enable the House to carry out the constitutional function I have outlined. I have suggested referring either the Bill or specific issues to a Select Committee, under Standing Order 8.118, which can take evidence in private and publish a report, or—an alternative as suggested by my noble friend Lord Anderson of Ipswich —to seek a report from an individual. I would hope that the report would enable us to do our constitutional duty, find the right answer and be able to reassure everyone that we had, on this extraordinarily difficult issue, made a decision where the safeguards were right and that was practicable. I have written to the Minister and discussed this with her. I very much hope that a way forward can be found.
