Those authorities would be defined in other pieces of legislation that identify who has the responsibility in the event of an emergency. What this legislation says is that if a victim is to come forward with a claim for damages, that this is one of the heads of damage that would be compensable. So if the victim were able to say, “Yes, I undertook a cleanup because I was ordered to by a competent authority”, that is what the victim would have to show to the court or to the tribunal, and then it would be compensated.
