The right hon. and learned Member for Beaconsfield (Mr Grieve), my right hon. Friend the Member for Holborn and St Pancras (Frank Dobson), the right hon. Member for Haltemprice and Howden (Mr Davis) and now the hon. Member for Brighton, Pavilion (Caroline Lucas) have all argued, from slightly different standpoints, that the ideal situation is to have some sort of judicial process. I do not think anybody could argue against that from a democratic and human rights perspective. In cases in which there is the possibility of a prosecution or other judicial process to bring about the type of outcome that we desire, that is clearly the preferred option.
As I see it, the choice is between the measures in the Bill—temporary exclusion orders with a managed return—or a form of judicial process that might be even worse than that. Perhaps the Home Secretary will correct me if I am wrong, but in almost every case I can envisage that would be affected by this process, the information that will determine the trigger of a temporary exclusion order would be based on intelligence—she is not shaking her head in disagreement, so I will assume assent on that point. If that is the case, any form of judicial process to verify or authorise that process would inevitably involve wholly or partly closed proceedings. It would be impossible to give evidence from intelligence in open court for all the reasons that we have repeatedly debated. Although that is the ideal situation, given the presumption that in most, if not all, of these cases the evidence will be intelligence based, it will be difficult to rely solely on a court proceeding, no matter how it was constructed or held, other than on the basis that it would be either closed, or at very least semi-closed.
