Chair, this is the second time this has happened, so I'm going to read from Marleau and Montpetit, on page 863, chapter 20 on committees. It says:
Particular attention has been paid to the questioning of public servants. The obligation of a witness to answer all questions put by the committee must be balanced against the role that public servants play in providing confidential advice to their Ministers. The role of the public servant has traditionally been viewed in relation to the implementation and administration of government policy, rather than the determination of what that policy should be. Consequently, public servants have been excused from commenting on the policy decisions made by the government. In addition, committees will ordinarily accept the reasons that a public servant gives for declining to answer a specific question or series of questions which involve the giving of a legal opinion, or which may be perceived as a conflict with the witness’ responsibility to the Minister, or which is outside of their own area of responsibility or which might affect business transactions.
Again, through you, Chair, we need to stay on focus. We cannot ask the witnesses about areas that are confidential.
