The point that my hon. Friend the Member for Brent North and I have been making is that post 1981 it has been clearly established that the precautionary principle, agreed at Rio, should apply, and it is missing here. It is the reversal of the burden of proof that will be missing if we stick to the 1981 Act. It is important to reflect in the Bill the extent to which the precautionary principle has been accepted.
