My Lords, Amendments 76, 77, 78 and 79, in the name of the noble Baroness, Lady Ludford, enable us to discuss the state threats prevention and investigation measures. As she outlined, Amendment 76 seeks to set a 14-hour limit on the time that someone subject to such a measure has to remain in their residence. Amendment 77 would require the Secretary of State to receive confirmation from the police that prosecution is not realistic, rather than requiring only consultation before a measure is imposed, as outlined in Clause 44(1). These are simple but important amendments, as the noble Baroness, Lady Ludford, outlined, and the Government need to respond to them logically, particularly as they are recommended by the JCHR. In Committee last time, we all referred to the importance of the JCHR recommendations that come before us. It is particularly important that questions such as these are asked because, although we accept that STPIMs are a useful tool to have available, they impose intrusive restrictions on an individual, outside the criminal justice process, as civil measures.

In view of Amendment 76, if there is no time limit, what is acceptable? Are 20 or 21 hours acceptable? As the noble Baroness, Lady Ludford, pointed out, these are essentially curfews on an individual. Although they may be justified—no one is questioning the fact that sometimes they may be necessary—some thought from the Government about what we actually mean by the imposition of time limits or curfews on an individual, and how that might be arrived at, is important. Secondly, should we not always seek to prosecute, as Amendment 77 seeks to do? The police confirming that it is not possible is a real protection, while not compromising national security; again, that is the aim of all of us.

On the more general question of STPIMS, legal aid will be available to individuals but, if they are to challenge effectively, will individuals subject to such an order be fully aware of the reasons why it has been imposed and able to challenge the imposition of such measures? Who will oversee the use of these powers? Can the Minister reassure us that, in making such a decision on application by the Secretary of State, the courts will be given all the information that they need to properly inform their decision, and that they will not be used arbitrarily, out of frustration that a criminal prosecution cannot be pursued? That was a really important point from the noble Baroness, Lady Ludford: this is not a substitute for prosecution but something to be used where, for whatever reason, it is simply not available. But we need some reassurance that criminal prosecution will always be pursued as the first option.

We accept that there is a potential need for such measures, but, given their civil nature and the very real impacts on the liberties of individuals, even if necessary for national security reasons, they demand of us the need to be ever more vigilant when it comes to freedoms and human rights within a democracy. Like the noble Baroness, Lady Ludford, I look forward to the Minister’s response.
