Spot the difference

On 21st June 2016, in reply to a different query, Thurrock’s Planning and Transportation department re-sent me the original plans. I once more replied that the plan showing ‘current’ layout of the driveway in my opinion differs greatly to the actual ‘current’ (as of 30th June 2016) driveway. Both ‘current’ and ‘proposed’ show it as being straight, as if no changes to the layout will be made; however the ‘current’ driveway is curved!

A senior member of the planning department had stated in a lovely PDF that the extension would oversail the existing driveway parking area which is accessed via an established vehicle crossover and would not allow the owner to park vehicles in a different part of the site to that used currently. What I want to know is, how is this possible if the ‘current’ driveway layout submitted was incorrect (as I feel it was) and that as I keep saying, the driveway is partially changing position?

Whether my belief is right or wrong, why have my questions not been addressed and was any due diligence done (i.e. check the land registry against the plan)?

If there was an error on the ‘current’ plan, I am sure on the applicant’s behalf this was accidental, however how can the planning department not have spotted this or if it was correct, why has this not been concisely advised to me?

If incorrect, then I believe it would be contrary to the senior official’s statement, so would the approval still be valid?
