Thank you very much.
I want to go back to what Mr. Turnbull said. Some good questions have been raised, and that's necessary for debating purposes.
We've discussed at length the number of cases the Commissioner has handled under the present legislative framework. I've questioned the parliamentary secretary, the minister and the deputy minister on the subject. We can agree that amending the act could increase the number of cases and expand the case law, for example, which raises the matter of expertise.
To my mind, expertise has to be acquired at both the Commissioner's office and the tribunal. I think this is a something of a side issue. We're interested in knowing what expertise has been built at the Commissioner's office.
How many of the Commissioner's decisions have been challenged in Federal Court, and how many of those were invalidated?
