I thank the noble Lord, Lord Beecham, for moving the amendment, which I say at the outset we are not in a position to accept. However, let me give an indication as to why sunset clauses are not necessarily appropriate here. Apart from anything else, I am trying to get my head around the idea of a sunset clause for litigation which could go over a period of time and it is difficult to think that you might have to sunset something. A case might start under a particular form of procedure and, if the sunset clause was effective, that procedure could be reverted in midstream.
There are also other considerations because this goes beyond what is proposed for the closed material proceedings we have been discussing. In relation to the case of Norwich Pharmacal, one of the primary concerns we are seeking to address is how we provide reassurance to those who give us important intelligence information so that we can protect information shared with us in confidence. A time-limited protection would undermine any reassurance we were able to give.
