I've just been reading the Standing Orders with respect to the study of a point here, and I draw your attention to this. It says, with respect to the study of an appointee or nominee:
The committee, if it should call an appointee or nominee to appear pursuant to section (1) of this Standing Order, shall examine the qualifications and competence of the appointee or nominee to perform the duties of the post to which he or she has been appointed or nominated.
And that's it. We're not here to ask him about his interpretation of legislation that is before the House.
