Investigatory Powers Bill

I will make just one very brief point. These amendments on modifications relate to an area where the system could—and I use the word “could”, not “will” or “would”—be abused, in the sense of a significant modification being made to a warrant perhaps not having to go through the kind of process one would have to go through with the initial warrant. I hope the Minister might respond in a rather wider context than the specifics of the amendments and set out why the Government believe, as far as the Bill is concerned, that the modification process cannot be used to achieve a major change in a warrant without having to go through the proper procedures of getting judicial authorisation. To some extent, I think that what lies at the heart of this issue on modifications is wanting an assurance, which can be given really only by spelling out the process that would prevent the system being abused in this way.
