I'm just looking at the wording in proposed section 12, which does refer to circumstances amounting to gross negligence.
As I understand the policy, the policy of the government has always been that an operator should have recourse against any party who would intentionally cause damage to an installation.
The point about gross negligence would be that the principle of the bill is that liability of an operator is exclusive and absolute, and that therefore the issue of negligence of other parties does not arise at all in terms of proof of damage. Causation in terms of nuclear accidents can be very complicated to prove, so the principle is that it is absolute and exclusive.
