I would not be prepared to say that only South Africa and Canada have that exclusion in their legislation. I would have to verify that and do a bit more of a comparative analysis for you, which I can provide.
More to the point is probably the jurisdictions in Canada. At the federal level, we are one of the few jurisdictions, if not the only one, that has cabinet confidence as an exclusion under the legislation--i.e., there's no right of review from the commissioner's office, which really goes against the fundamental tenet of access to information where we want to have an independent oversight mechanism.
