We have to keep in mind that the present topic requires a reformulation of your question:

For which areas of international law can scientific and technological assessment be relevant?

For the most of them, but I will only name some areas where science and technology are very important for a correct legal assessment:

1. International environmental law;

2. International IPR protection

3. Global antitrust law

4. International trade laws and standard setting.

The innovation of today can set the standard of tomorrow and it is important to be able to cope up with tomorrow in the field of trade and competition. The scientific research also establishes what can be considered to be sustainable technology, what is dangerous for human/animal health etc

It would be helpful to have a definition of innovation. What do you mean by innovation? Do you rely on the legal definition used in the field of the IPR? Do you mean some new knowledge that can be used in order to manufacture a new or improved product? We discuss even process innovation today. Your question is too wide, it must be narrowed down a bit.

Thanks for your answer, in this moment i try to focus to discussion.
