Yes, Mr. Chair.
I do not think it's unparliamentary to suggest to a witness that she or he is deliberately avoiding answering the question, because I think that was clearly obvious, I suppose. Maybe stating the obvious is a bit much in some cases, but it's certainly not unparliamentary to do so when you ask one question and you get another answer. You can point that out.
I think that the decorum has been maintained. The fact of the matter is that we did have a witness who was stonewalling—it's just an adjective that is well known and understood—and I don't think there's anything wrong with pointing that out to a witness. I don't believe the point of order is, in fact, valid.
