djjc,
Your LA do appear to be somewhat cavalier in their approach to the regs.
As your appeal on the 1st July was presumably a multiple appeal (more than one appealant) then the parent who postponed their appeal should have told either it went ahead as agreed on the 1st July with them not present (a tad naughty) or their appeal became a separate appeal all together. Postponing you not getting the result of your appeal is unacceptable. Whilst it is not illegal to dow hat they have done it is not fair and I would say gives a problem in that the panel members have to remember what happened and was said over a week previous.
In terms of the handling of the late applications, I think that there are a number of points. Firstly the LA have not followed their stated policy, which is "Late applications will not be dealt with until all of the on time applications have been dealt with, even if your child has special circumstances or has a sibling at the school." That is absolutely clear. I suspect that most people would not differentiate between "special circumstances" and "exceptional circumstances" so that should not change any decision.
So we are left with this statement that the Ombudsman had previously ruled that late applications in exceptional circumstances must be admitted, even if not part of the published admission criteria. One of my LAs says in their application book "Exceptionally where in the Council's view there is a genuine reason for the late application, for example exceptional medical reasons preventing an earlier application, late removel into the area due to a recent house move, a late application may be treated as on-time, where it is practical to do so. Whilst I can't find any Ombudsman decisions to back that up I would strongly suspect there are.
Personally as a panel member I would not have accepted your quoted example as the parent presumably had from September 1st till the closing date to process the application but did not, the car crash just happened at an unfortunate or convenient time depedning on how you look at it.
However the key point to me is that my LA has spelt it out in the application document and your LA is doing it because they know about it but have not indicated that is what will happen. I suspect that the Ombudsman would see that as maladminstration as they are not carrying out their agreed procedure.
