Terrorism Prevention and Investigation Measures Bill

My Lords, we have to bear in mind that as the Bill now stands, the initiator of this procedure is the Secretary of State with responsibility for national security. The Secretary of State has available to him or her all the information that the state can provide, including on a secrecy basis, on these matters. When a court is deciding something, the balance of probabilities is a suitable standard because it is not expected to believe one thing or the other; it is to accept the balance of the evidence one way or the other. Requiring the Secretary of State to believe is a higher standard than the balance of probabilities. I cannot believe that the Secretary of State would be entitled, on a mere balance of probabilities, to come to the belief that this is what happened. Of course, Secretaries of State might be rather special, and they might be able to come to a faith and belief without much in the way of evidence. However, that is taken care of by the language in the Bill as it stands, that the belief must be reasonable. So it is not only belief but a reasonable belief. In other words, the Secretary of State must have available to him or her information as a result of which he or she comes to be convinced that the person has engaged in the activities that the noble Lord kindly laid out for us. I agree that it is an extremely serious matter but the language in the Bill is suitable to a situation in which a decision has to be made, not by someone who has to review the evidence as an impartial judge but by someone who comes to the evidence with the executive responsibility to take the necessary action. In my view, this requirement that the Secretary of State should reasonably believe that the person in question has been involved in these activities, is a stronger and more reliable basis for going forward than a mere balance of probabilities. It is difficult to see how one could be convinced on the balance of probabilities alone.
