I wouldn't presume to agree whether or not it's appropriate for you to have that discussion. All I will say is that this is the process that protects the requester across the board, that the Information Commissioner serves as a court of not even last resort, but a way by which requesters can have the discretion that's exercised by officers in a supplying department, to have those judgments examined by an outside officer, and an officer of Parliament.
