Thank you, Madam Chair.
The calendar as circulated lists the witnesses I have been able to confirm. The calendar was circulated to members.
The witnesses who have declined the invitation have been omitted. Basically, members can make the deduction: the people who aren't on the calendar have all declined. That's where I am with that.
The ones who haven't been confirmed are still on the calendar, but there is no “confirmed” shown beside the name. That's the only difference.
