As a senator, I have tried to find that out. I don't have the answer. I am told that the Library of Parliament won't do that because it's a political question, and the Department of Justice will take steps in that direction if they are directed by politicians to do that.
I think it is a question of putting a proper legal team together, with the awareness of what the UN declaration is all about, to make sure that they do a proper assessment of laws and regulations.
