The answer to your question depends on what the next step would be after the public agency's response.
Ministerial responsibility does, after all, rest with the minister. It is the minister who is accountable for their department's actions. Unless an access to information system is adopted that is parallel to government activities, as we have just discussed, the responsibility lies with the minister. They are accountable for the documents that must be disclosed.
The reason I am talking about the next step is that, if there is then an independent, adjudicative process, which makes binding decisions, I think this would provide a balance of protections, which would in turn enable us to achieve our objective as regards access to information.
