Thank you, Madam Chair.
To the reference you made earlier, the change had to be made because, as you know, one of the witnesses has to undergo medical treatment, so it wasn't a matter of horse-trading. We were just trying to show some compassion for one of our public servants.
As far as not naming witnesses goes, it has been customary for us to do so, so in keeping with convention, I feel, as we did with different studies, we should continue to identify, just to ensure that no substitutions are made where it could be important to have the actual person we were asking for.
