My Lords, I listened very carefully to the noble Lord, Lord Paddick, and his explanation of his amendments, but I was not at all convinced. If we believe that there is a need for the Bill, which I do, but have reservations about some of the issues around encryption, we have to ensure that the relevant agencies have some tools in their kit box. One of those tools has to be the ability to interfere with or look at the specific equipment. What the noble Lord is trying to do is to restrict the availability of that power to such an extent that it would effectively become almost useless. It would simply be available if you have one named individual. Therefore surely it is right that a significantly broader power should be available to engage here.
The question that the Minister who is going to respond needs to answer is this: how will the test of proportionality be applied in such cases? Presumably it is not proportionate to have such a broad sweep contained within the authorisation that it is inappropriate and overly onerous. The mechanism is therefore this: how is it determined that this is a proportionate and proper use of the power, and can we and the public be reassured that the mechanisms exist to ensure that that proportionality is adhered to?
