You're requiring that it be a 30-day waiting period, I think, to ensure that the department isn't appealing. In most cases we've heard, even under the current system, rarely do these things go to court, so I think you're going to find that the Information Commissioner, in most cases, is the one who is publishing the order and making the determinations and findings. However, in a rare case, it's not going to be published right away, and a court will make the law.
