This intends to shore up, if I can use that term, the government's assurances as to an exemption. We can imagine a scenario in which an exemption is made and a supertanker has been allowed through. This amendment would put a time limit on the exemption, so that there couldn't be a rolling.... Yes, it is shipped by ship, but if it's done in private, in secret, you can just start exempting ships. Again, this is not to cause discomfort for the current government, but one could imagine a moratorium that you could poke a hole through just by exempting a bunch of ships.
It would also, following the exemption, require a public review of the exemption, so that there would be a review of why it was done and if it met the test, rather than having to go through any legal proceeding where the concern often is that advice to a minister can be deemed non-admissible in court. If someone comes forward and gives advice to a transport minister in future and says, “We're exempting the following ships”, we no longer have access to information over that advice that was given. It is very difficult, as has been proven many times, as the chair would know, to pull any of that evidence forward in a court of law because it is deemed a privilege of Parliament.
