No. The government is not and should not be allowed to hold back information from you unless they can find something in the act saying that this is why, for certain policy reasons, you can't have it. If they don't have that, they have to give it to you. That's what the commissioner's role should properly be: to say that you're entitled to it, so give the man his documents.
