This will end when the claim that is issued is either discontinued or struck out. However you will need to follow the advice.
For now, simply follow this advice:
There is no legal obligation on the
known keeper (the recipient of the Charge Notice to Keeper (CNtK)) to reveal the identity of the
unknown driver and no inference or assumptions can be made.
The operator cannot rely on PoFA which means that if the
unknown driver is not identified, they cannot transfer liability for the charge from the
unknown driver to the
known keeper.
Use the following as your appeal. No need to embellish or remove anything from it:
I am the registered keeper. VCS cannot hold a registered keeper liable for any alleged contravention on land that is under statutory control. As a matter of fact and law, VCS will be well aware that they cannot use the PoFA provisions because Bristol Airport is not 'relevant land'.
If Bristol Airport wanted to hold owners or keepers liable under Airport Bylaws, that would be within the landowner's gift and another matter entirely. However, not only is that not pleaded, it is also not legally possible because VCS is not the Airport owner and your 'Charge Notice' is not and never attempts to be a penalty. It is created for VCS's own profit (as opposed to a bylaws penalty that goes to the public purse) and VCS has relied on contract law allegations of breach against the driver only.
The registered keeper cannot be presumed or inferred to have been the driver, nor pursued under some twisted interpretation of the law of agency. Your CNtK can only hold the driver liable. VCS have no hope should you try to litigate this matter, so you are urged to save us both a complete waste of time and cancel the PCN.
