The act doesn't set out an appeal mechanism or anything like that. It prescribes a limit on the authorities of the parliamentary budget officer to obtain information. It is ultimately a question between the department that has been asked to give the information and the parliamentary budget officer as to whether or not the information being requested falls under the information that is not to be provided from the two categories I mentioned: personal information and cabinet confidences.
On the other body of information I was talking about, the parliamentary budget officer can receive it but simply isn't in a position to disclose it unless the disclosure is necessary for the discharge of the mandate. He is just meant to treat it in a confidential manner.
Ultimately, it's going to be a discussion between those two parties. If there's disagreement, if the parliamentary budget officer wanted to insist on receiving the information, because it is a law it could go through lawyers or to the Federal Court, to get the interpretation of a judge.
