I am aware of at least four:
CH/3629/2002
CH/2741/2003
CH/0454/2005
In all of these cases, the Commissioners recognised that LAs do not process changes the instant they barrive in the office and that there is inevitably a turn-around period – you wouldn’t call that an error.
The last one in particular is quite surprising: the Council got away with a delay of almost 2 months (which included Christmas and New Year)
By way of contrast, in CH/0881/2005 (also including the Christmas and New Year break), the Commissioner felt that 11 days ought to have been long enough to deal with new information and failure to do so was therefore an error.
So it’s a piece of string job, I’m afraid
