I think the 2009 resolution came right on the heels of the peace agreement. I think it would be normal for the Human Rights Council to welcome the peace accord. In later resolutions, however, in later sessions of the Human Rights Council, it would be normal for the council to look at the progress that has been made towards observation of human rights in Sri Lanka and progress towards peace and reconciliation. In fact, the council found that wanting, so that was reflected in the resolution.
