Dave,
I really have no inclination to enter into a debate about this issue which is wholly unimportant to me anyway.
I merely mentioned it in passing. My "understanding" was gained from a conversation that I had with somebody who (with respect) is much better placed to know about the current situation at Marple Hall than you are. If you are genuinely interested in whether it is true or not then can I suggest that you make a simple phone call/email to either the Headteacher, The Chair of Governors, or the Executive member for Schools at SMBC. Apologies, I've duplicated here as person 2 & 3 are one and the same. I am sure they will be only too pleased to tell you of the school's intention. When you've established that - then you can speculate on the legal hoops and the timescale.
