The original question, unless I've misunderstood, is whether parents who've put down more than one choice
could be disadvantaged ......
does anyone know of an actual case where guidlines weren't followed and child A ended up with a place because of this and child B didn't but when it came to appeal although the authority were in the wrong child B still missed out because there was not enough room and child A gets to keep its place regardless.
...or alternatively this has happened and child A has its place given to child B be because their needs were equal and they followed correct procedure.
It is unlikely that child A would have its place taken away if it's the authority's fault. The authority would have to rescind the place very swiftly (within days).

I've not come across your first example in practice. I believe that an appeal panel would do everything possible to remedy any maladministration - my only proviso is that there might come a point where the total number of children is beyond the school's capacity to cope, and the appeal panel would then be required to take that into account.
If the headteacher were to turn up as a witness at such an appeal, and in answer to a question were to state "We could cope with all these children," it would strengthen the parents' case!
