I say, in passing, that although it is a long time since the Criminal Justice Act 2003 was passed, the hon. Lady, with her experience, will appreciate that careful preparations with the appropriate training are needed for the introduction of such important powers.
I rise not to give the hon. Lady examples but to repeat what I said earlier: I do not have any examples to give. I cannot foresee any circumstances in which the certificate would not be issued when both limbs of the test are satisfied. I say again that there may be unforeseen circumstances, which I cannot predict, that may require some discretion by the DPP, but fundamentally it is a point of principle. In the end, it is for the DPP to make that decision and we leave it to him, as it is at present, to use his discretion to make that judgment. I see no circumstances in which that would happen, but we have to leave it open to the DPP.
