I agree with the addition.
I have just one question. When we are talking about individuals, does it mean the witnesses appearing before the committee, or can it be any individual present at the meeting?
The educator in me wants to stress the point that, in French, we have to correct (a), (b), (c) and (d).
I see that it is actually a list of conditions. I am just afraid that there could be another condition. I would like to see a fifth point. Certainly, the committee is free to decide to hold a meeting in camera should that fifth situation arise. It is at the committee's discretion, of course. It can be anyone or any combination of members present.
I dread lists that are too defined, because one can never think of everything that might come up.
