In 20 seconds, I would say this. For both the reasons for referral and the review panel report, there should be a duty to publish. The standards should be that the council “shall make public the reviewing member’s written reasons for referral”, and, in a separate clause, make public the review panel report “to the same extent as the council would be obligated to disclose them in order for them to form part of the certified tribunal record in the event of judicial review proceedings”.
The point is that we can get these things. We just have to go to court. Why hold them back and force citizens to pay money to see things they can get through a judicial process? Whatever the standards are that you can maybe hold back some of the stuff—for reasons of anonymity, privacy or whatever—would still apply, but whatever you'd have to give up, were there JR, you'd have to give up proactively.
