Mr. Esau is exactly right, and he says it better than I do. There is subsection 13(1), which would have dealt with information provided in confidence to Canada by another government, but that's not the section that was used here. That's the only section I would have thought might be used. For instance, if Afghanistan had said yes, they torture over there in Afghanistan, then perhaps Canada would have an obligation not to divulge that. However, a section of the act other than subsection 15(1) would then have had to be used.
The Department of Foreign Affairs and International Trade clearly does not believe this is information received as a diplomatic confidence. That's not the section of the act they relied on.
