I agree that it is entirely plausible that a CEO would begin to check cars at the given observed time. I don't agree that my vehicle was parked there then though, I would guess it was parked just before 9am, but can't prove this. I didn't actually check as I knew I'd definitely be parked there for less than two hours.
Hence my initial question; "Do I have to accept that the observed times by the CEO is taken as 'gospel' and it's a case of my word versus theirs, or is their a case to challenge it?"
As the CEO took no photographs when they first observed my vehicle, I am assuming that they made a note of my vehicle registration, which presumably is now recorded digitally.
BANES have form for procedural impropriety and I have in the past successfully challenged, at adjudication level, three Bus Lane and one parking PCN's. In the earlier days of PePiPoo I helped several people to successfully challenge the same incorrectly signed Bus Lanes.
My initial thoughts are that without supporting evidence on when I first parked, I have no case, but on the basis of 'if you don't ask' I'm here now.
