In order for the operator to be able to transfer liability from the unknown driver to the known Keeper, the notice MUST fully comply with ALL the requirements of PoFA paragraph 9(2). There are 10 sub-paragraphs that list all these requirements. One of them is paragraph 9(2)(e)(i) which states that the Notice MUST:
state that the creditor does not know both the name of the driver and a current address for service for the driver and invite the keeper—
(i)to pay the unpaid parking charges; or
(ii)if the keeper was not the driver of the vehicle, to notify the creditor of the name of the driver and a current address for service for the driver and to pass the notice on to the driver;
Now let's take this element:
"...and invite the keeper—to pay the unpaid parking charges"
If you read the notice carefully, you will see that the notice only says that the Keeper must pay the outstanding amount if they were the driver or, if they were not, provide the drivers details and pass on the notice.
As there is no legal obligation on the Keeper to identify the driver and they only tell the Keeper to pay if they were the driver, then this does not satisfy the requirement for there notice to "invite" the Keeper to pay it, irrespective of whether they were the driver or not.
As there is no explicit invitation (or any synonym of the word) to the Keeper to pay the charge, the requirement for the notice to invite the Keeper to pay it has not been met. Just like someone cannot be mostly or even substantially pregnant. They either are or they aren't, the Notice cannot be mostly or even substantially PoFA compliant. It's a binary issue. It either is or it isn't POFA compliant. In this case it isn't.
Not that you'd convince a thicko POPLA assessor of that level of detail. However, if it ever got as far as a court hearing in a claim (highly unlikely) a judge would take a different view and I have successfully argued this with a district judge.
There is also the issue that the notice only mentions "We, the creditor" without identifying if "We" is the landowner or just the operator. Without specifically identifying the creditor, the notice is in breach of PoFA 9(2)(h).
These are all technicalities that would only have real effect in court, not with the farce that is POPLA.
