Well if we are going to cut and past our discussion into more than one thread mate... and I am being accused of being paranoid!
While you are right in most cases I am not sure about the ability of the SoS to call a public inquiry on this element of the LDF (in fact any LDF or part of it), mainly because that sort of what the LDF process is already, a public inquiry! Also, I suspect (believe it or not) that some other issues of the LDF site specific document are going to be even more contentious... think traveller sites, I think Newmarket might be minor in some ways!
If he could do that, you are forgetting one key issue, the magic 95ha, which was a recommendation by exactly the same office (albeit with a different boss) and is now untouchable until 2021 as it is legal requirement of the in-force core strategy. So the SoS office can't simply say sorry, find a more suitable site, unless they actual is one (and is there... because you better tell someone quick?), they can't change their mind either. All the four sites identified are currently Green-belt (as you know) and the other three sites are all currently agricultural only, this means they come further down the list than Newmarket which is reclaimed land, so to be honest three other sites get knocked back before Newmarket, the biggest and most suitable of it's rivals (so to speak). You changing your mind yet... I am sticking with highly likely!
I will check this but as far as I am aware the SoS office can only make recommendations to changes to an LDF and not force a public inquiry or force changes, the final say belongs to Wakefield MDC. They have never failed to vote for a recommendation in the LDF process made by the SoS office so far but if he recommend taking this out of the LDF, I suspect they might not listen to him, especially if he didn't have any better sites to suggest! Leeds objection will not carry the weight here (like it appears it did for the application) as well, they should have been more vocal at Core stage, any objection from them now is sour grapes.
This boat has sailed and while it has not quite reached port they are getting ready to dock and the only thing likely to stop it is an alien attack from outer-space... so yes, I am sticking with highly likely (unless the aliens support Cas!).
In respect of PI on the current application, then your assumption is likely to be the other way around... if it actual gets to a PI now, the LDF overtaking a PI could actual mean it never happens! I do understand that the planning inspectorate can still rule, at any stage, to send this back to Wakefield if circumstances change!
PS. I like you best as allmatt, we disagree but I can actual debate the issue with you. Drop the BigAlf and just stick with allmatt on hear (I won't tell the Cas board).
