I have a better sense of the mechanics. In some cases it may be that a government department is saying that they are not going to release something. The commissioner looks at it and says that it falls under the appropriate categories in there, so there is cause under the act for them not to release that information; but because it would be in the public interest, the commissioner makes a recommendation in the Newfoundland model to say that this should be released. Then, if the government wanted to challenge that, they would have 10 days to go to court to say that it doesn't really fall under the criteria of the public interest override, and they want to maintain a right under other provisions of the act to not release it.
