My Lords, perhaps I can assist my noble friend with some comments. Self-evidently, I was a Minister in the Labour Governments of 1997 to 2010, and the power to make these regulations came into play originally when I was in government. But self-evidently, nothing happened between 2010 and the regulations being brought forward now.
I am not party, as the noble Lord, Lord Davies of Gower, is not, to what happened in those years because for nine of them I was in opposition and, for five of them, I was not in Parliament. But I can potentially help my noble friend by saying that it was initially planned to extend the PACE powers to Northern Ireland in 2013, alongside the same processes being undertaken in England and Wales. I am advised that limited resources and/or competing priorities meant that that was not implemented. There was also the additional factor of the closure of the Belfast criminal financial investigations office between 2017 and 2022, which made it difficult to pursue those regulations until now. Questions of why those decisions on resources or legislative capacity were made and why the office was closed are beyond my capacity, but those are the facts of the assessment that has been made. That is what I have been advised.
My noble friend also asked what changes these powers make. The regulations give officers a number of powers that they do not already have. Immigration criminal investigations in Northern Ireland will now benefit from a number of provisions of PACE, notably: Section 19 in relation to powers of seizure in relation to evidence of non-immigration offences; Section 8, relating to warrants; Sections 9 and Schedule 1, which give access to excluded or special procedural material; Section 20, giving extension of seizure powers to include information on computers; Section 46A on power of arrest for failure to answer bail; and Sections 18 and 32 on simplified powers of seizure and search.
