Thank you for the question. I'll ask Clark to answer part of it.
On the first part of your question, dealing with the legislation, citizenship law is exceptionally complicated. And it's probably one of the rare areas of public law in which decisions made by legislators decades ago, parliaments ago, generations ago, still have some sort of carriage. It's not an area that we see at all in the immigration world. We don't deal with the 1952 Immigration Act; it's just not part of our environment. Yet with citizenship, because citizenship can be passed on generation upon generation, those parliamentary decisions that were made in 1946 and 1976 have carriage.
So we do have to be conscious of that. That is just a bit of the context around your question. I'll ask Clark to reply to the second part.
