Cock Up, Conspiracy or just Business as Usual?

EaCoxs Park 120915 rlier this month the enquiry into the status of Cox’s Park in Hadleigh was adjourned on its first day after additional evidence was submitted by Babergh District Council. Babergh wishes to build housing on the parkland and since 2013 residents have been trying to have the park designated as a town green.
The inspector quite rightly adjourned the enquiry for four weeks to allow the residents to inspect the 60 pages of new evidence presented by Babergh and this evening (Thursday 25th) there is a meeting of Hadleigh Town Council to review the situation. The meeting is open to the public.
This is all very well, but what were Babergh thinking of dumping over 60 pages of evidence on the enquiry on its first day. Did they think they could disrupt the decision process by denying the residents the chance to review the evidence? Did they think that such a manoeuvre would work in their favour?
No explanation has been made as to why this stratagem was adopted by Babergh. The quotation from Babergh’s Strategic Director (People) merely refers to their awareness “of the strength of local feeling for East House and the surrounding land.” This of course begs the question why did they use this tactic. Was it deliberate? Was it happenstance? Or is it an example of what they usually do –  blunder onwards? Is this Tesco all over again – blindly going forward when the evidence indicates that the well being of the town and the wishes of the people demand otherwise?
