The only comment I would make, Mr. Chairman, is that subsection 15(1) is a discretionary exemption. In the course of an investigation by our investigators, we would clearly challenge the rationale that was applied in selecting subsection 15(1). We can share that rationale if we accept that it has been applied correctly, and if it was not applied correctly we would first pursue the disclosure of that section. Quite often that occurs because we have challenged the rationale. Then it could be a legal opinion that we are in fact challenging within a department.
So I think it's important to note that subsection 15(1) is discretionary. It's not absolute. A lot of discourse in the context of the investigations takes place, such as “Why did you put this?” and “Why did you invoke that?” and “Can we see the rationale?” and “Can we see the legal opinion?”, or “Well, maybe you've gone too far here.” That kind of exchange takes place at the investigative level. Ultimately, it ends up on my desk by way of a report.
