Standing Order 111(2), Mr. Chairman...and if you refer to Marleau and Montpetit, page 877, just before the topic of subject matter, studies, as I quoted:
A committee has no power to revoke an appointment or nomination and may only report that they have examined the appointee or nominee and give their judgement as to whether the candidate has the qualifications and competence to perform the duties of the post....
That is what we have to report back on. It's very clear in the Standing Orders.
