Perhaps I can speak to your examples that focus on new products and new substances.
First, let me suggest that it may be that the committee will decide it would be appropriate to ask us to come back and provide more detailed advice on how we implement the new substances regime.
The new substances regime is fundamentally precautionary. The new substances regime says that you cannot introduce a new substance until it has been assessed. In the regulations, it prescribes the information that you have to provide to us in order to enable us to make an assessment of whether there's a risk. It's not quite reverse onus in the sense that it doesn't say that you have to prove; it says that we decide what information we think we need to make that judgment. We don't have to go and get it. If you want to use the substance, you have to give us that information. Then we make the assessment.
