They weren't negotiating then. As I remember, the document came from the Department of National Defence for comment. The obvious people who would comment in a substantive way would be the human rights division and the legal affairs division, the legal bureau. It was sent to the area I worked in called START--the stabilization and reconstruction task force--which was just kind of getting up and running at that point.
On April 14th, 2010. See this statement in context.
