Mr. Holder raises an important question. On the parliamentary practice and procedure with regard to obtaining documents or witnesses answering a question, if they can give a reasoned explanation as to why it is improper for them to do it, you won't get the documents if you accept the reason or explanation as to why they can't answer the question.
We won't know whether what we've asked for is sensitive unless they raise a concern. Our request does not mandate them to get it. If they can give an explanation to the committee that it's commercially sensitive and they would prefer not to release it, the committee can accept that. That's the practice.
