Mr. Chair, in response to that point of order, I will just observe that what is appropriate is if you think something is out of order then inform the witness that in your judgment, it's not necessary for them...that if they choose not to respond, it's up to their discretion.
I'll mention further that the witness has a very impressive record of having dealt with issues that require discretion. The witness is better qualified than anybody in this room to determine whether or not a question that one of us asks has the effect of putting him in a position of being unable to answer without violating his mandate.
I think that is the appropriate course of action. Actually not allowing the witness to answer and not allowing me to ask would be an inappropriate use of discretion.
