On the picture they have of me entering the car park you can clearly see me as the driver.
How would they know it was you? They have no idea what you look like.
Either way, what's done is done. Your next step is to start drafting up a POPLA appeal. Can you get evidence of the tariffs? One point can then be that you paid a tariff of sufficient value to cover the duration of your stay, and as such penalising you for a minor input error regarding the times is not pursuing a legitimate commercial aim, making the charge an unenforceable penalty.
Whilst this is Smart Parking, you should also include a point challenging them to prove they have a valid contract with the landowner to enforce parking at the site. Smart have had issued with this in the past, and often discontinue when it is raised in an appeal. Here's some wording you can use for this point:
No evidence of Landowner Authority - the operator is put to strict proof of full compliance with the BPA Code of Practice
As this operator does not have proprietary interest in the land then I require that they produce an unredacted copy of the contract with the landowner.
The contract and any 'site agreement' or 'User Manual' setting out details - such as any 'genuine customer' or 'genuine resident' exemptions or any site occupier's 'right of veto' charge cancellation rights, and of course all enforcement dates/times/days, and the boundary of the site - is key evidence to define what this operator is authorised to do, and when/where.
It cannot be assumed, just because an agent is contracted to merely put some signs up and issue Parking Charge Notices, that the agent is authorised on the material date, to make contracts with all or any category of visiting drivers and/or to enforce the charge in court in their own name (legal action regarding land use disputes generally being a matter for a landowner only).
Witness statements are not sound evidence of the above, often being pre-signed, generic documents not even identifying the case in hand or even the site rules. A witness statement might in some cases be accepted by POPLA but in this case I suggest it is unlikely to sufficiently evidence the definition of the services provided by each party to the agreement.
Nor would it define vital information such as charging days/times, any exemption clauses, grace periods (which I believe may be longer than the bare minimum times set out in the BPA CoP) and basic but crucial information such as the site boundary and any bays where enforcement applies/does not apply. Not forgetting evidence of the only restrictions which the landowner has authorised can give rise to a charge, as well as the date that the parking contract began, and when it runs to, or whether it runs in perpetuity, and of course, who the signatories are: name/job title/employer company, and whether they are authorised by the landowner to sign a binding legal agreement.
Paragraph 7 of the BPA CoP defines the mandatory requirements and I put this operator to strict proof of full compliance:
7.2 If the operator wishes to take legal action on any outstanding parking charges, they must ensure that they have the written authority of the landowner (or their appointed agent) prior to legal action being taken.
7.3 The written authorisation must also set out:
a the definition of the land on which you may operate, so that the boundaries of the land can be clearly defined
b any conditions or restrictions on parking control and enforcement operations, including any restrictions on hours of operation
c any conditions or restrictions on the types of vehicles that may, or may not, be subject to parking control and enforcement
d who has the responsibility for putting up and maintaining signs
e the definition of the services provided by each party to the agreement
