I am obliged to noble Lords for their contributions. We consider that this instrument is necessary to make sure that the SIAC procedure rules are consistent with the primary legislation, as has been acknowledged. SIAC does of course perform an essential function in dealing with appeals without compromising national security.
On the point made by the noble Lord, Lord Marks, and followed up by the noble Lord, Lord Beecham, there have indeed been about 14 cases before SIAC in the past year. There is only one party on bail from SIAC at present, pending a determination by the commission, so the use of these powers is extremely limited and I am not aware of any indication that that will increase in the foreseeable future.
On the point raised by my noble friend Lord Hodgson, I am not aware of the current position on re-interview by special advocates, but I will determine what the current procedural position is and write to him on that and place a copy of the letter in the Library. On the point about the condition of centres where persons are held pending determinations by the commission, I am not in a position to comment upon any adverse management issues at present, but I will inquire of the appropriate department as to what current work, if any, is ongoing with regard to that issue. Again, I will write to the noble Lord and place a copy of that letter in the Library.
