Justice and Security Bill [HL]

My Lords, the noble and learned Lord, Lord Mackay of Clashfern, has made that point twice. Does he recognise that although, as he said at the outset, there have been procedures in which material has been seen, but not by one party, those are not procedures in which that material is then replied upon by the judge to determine the rights and wrongs applicable to that party? This is in order to exclude that material and not to allow it in. Is that not the novelty of this procedure?
