I would just make one additional point. I was involved in the new substances notification regulations on organisms that are essentially biotechnology products. In the context of that process I tried very hard, as a concerned member of the public, to find out what the protocols were on claiming confidentiality for biotechnology products, which, as you are probably aware, are a huge concern of the public. How biotech products are dealt with is a very hot topic right now in politics.
The response I was given was that despite the fact that there are guidelines around how the department and notifiers shall deal with confidential information, the de facto operating policy of the department was to treat all of the information as confidential unless they received written consent.
I asked three different people and received three different answers. That seemed to be the consensus in the end, but from my perspective there's obviously some confusion, which is part of the reason why we feel the test to be met in order to claim confidentiality should be part of the legislative language and not just part of the guidance.
