As you'll know from reading the text of the bill, it talks about an identified oil tanker and it provides a test for when exemptions can be granted, which is predominantly to address problems with community or industry resupply. There is the broader test of the public interest, which we included in there just because, first, it mirrors what appears in other legislation, but second, it's impossible to predict situations where we might need to use the exemptions. We wanted to provide enough flexibility to deal with an unanticipated situation.
As I say, however, traditionally these exemption provisions are interpreted quite narrowly. Certainly the legal advice that we usually provide to ministers and officials is to stick very closely to the test.
