I read the TLERA news sheet and it seemed pretty reasonable to me.

It also said that the nursery was opened before planning permission was granted.

Opened without planning permission and in breach of a restrictive covenant. Does that suggest any type of pattern?

If I read correctly the application to the Lands Tribunal is to allow a nursery with 12 places not the current 24. Why not seek permission for 24 places if that is a perfectly reasonable use of the property?
