As I said, I'm not involved in such matters, so I'm not aware of any particular letter. I can tell you that section 38 of the Canada Evidence Act creates the duty on all participants to give notice when certain conditions are met, as I've indicated in my opening remarks. So if they believe that sensitive or potentially injurious information would be revealed during the course of a proceeding, then they would bring that notice to the Attorney General of Canada and that would have to be addressed.
