If I could add to this briefly, it's worth noting that the FOI statutes of 16 other jurisdictions grant an independent administrative appeal body the power to order record release. This includes Mexico, India, New Zealand, Scotland, and the United Kingdom.
Some critics say we don't need to amend the law because all we need to do is better enforce the ATI law we have now. That is not correct, because the great paradox, and a sort of catch-22, is that the law cannot be run effectively unless it is first amended to put enforcement powers into the law.
