On a point of order, this is not to question.... Well, it is to question something you've just done, but it's not to question the integrity of what you've done. I just want to find this out for clarification and future reference, because I have a feeling that the issue of relevance may come up again; I'm just saying.
As chair, are you actually allowed to call people on relevance, or do you have to wait for one of the members of the committee, on a point of order, to raise the issue of relevance? This is just so that we know that it gets done in the right manner in future.
