It is right that it is part of the construction of the legislation that created NSICOP that members must acquire a top secret security clearance. They become people permanently pledged to secrecy under the Security of Information Act. They have to deliver an oath of loyalty. They give up parliamentary privilege. That's been challenged legally, but I don't think the challenge, to be honest, is very sensible. That's the way NSICOP works. That is also the way that counterpart bodies in the Five Eyes work.
In regard, just very briefly, to Dr. Leuprecht's statement, NSICOP does not report alone to the executive. Of course, NSICOP publishes its reports and provides them. They are tabled in Parliament. NSICOP reports to Parliament, and that's an important function. We can talk about the ways in which the executive controls some aspects of protecting information in the unredacted versions of NSICOP reports, but that is perhaps a discussion for another day.
