I have just been reading the minutes of the Commission for Local Administration in England for the last few years and it would appear that the York office is in crisis. And has been for quite a while. They introduced a special initiative to clear the backlog of old complaints and this could be the reason why they decided to end my complaint without due diligence. Performance targets (and performance related pay) are obviously more important than justice to the York office staff.
Please contact me if you have also recently been stuffed by the York office in an attempt to clear their backlog of old cases to meet performance targets. Did you know investigators get performance related pay? The quicker they turn over cases the more they get paid. It would appear that the York office staff have realised it's more profitable to stuff a complainant than do their job properly.
