Perhaps I could read to you some of the rules having to do with the appearance of public servants. If you'd like that, I could.
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.
As a public servant--he is a public servant still in another department--he is confined to answering in this way.
