When it comes to the hearing, I strongly suggest you lead with the KEY legal point which is that you have only appealed as keeper because Elite notified you that 'you have now...internal appeals procedure' and for no other reason.
As the assessor will be aware, the 'Right to claim unpaid parking charges from keeper of vehicle' conferred by s.4 of Schedule 4 to the P...of F..Act 2012 may only be exercised, inter alia, after a Notice to Keeper has been served.
None has been served in this case as is clear from the creditor's evidence. It therefore follows as a matter of law that the keeper has no liability in this matter and I ask the assessor to direct the creditor accordingly.
And let's not worry about secondary issues, even whether a parking charge was due because IMO they are not relevant to achieving the objective. The creditor fails on the KEY point and that's all that's required....IMO.
