I think chapter 28, as it is worded, literally prevents that precautionary principle. This is a major issue in the negotiations between Canada and the European Union. The Europeans want to keep the precautionary principle. They believe that it is fundamental to protect the health of their people and the environment. They believe it is under threat, and the regulatory cooperation chapter bolsters their sense of vulnerability.
