All those photos show is a vehicle in a bay with no ground markings taken over the span of less than a minute.
The NtK is not PoFA compliant. It fails on 9(2)(e)(i) and (ii) in that there is no invitation (nor any synonym of the word) for the keeper to pay the charge and it also fails to tell the keeper to pass the NtK to the driver.
The NtK also fails PoFA on 9(2)(a) in that it does not specify a period of parking. It simply specifies a moment in time.
On that basis, the keeper cannot be liable for the charge, only the driver whose identity is unknown to PCM. Additionally, there is no evidence of any contravention as the vehicle appears to be within a bay. There are no markings to indicate that the location is not a bay or that it is an area that is not available for parking.
The evidence does not show that the driver did not consider any signage as it is evident that the driver is still in the vehicle over the period of less than a minute. So it breaches the new joint CoP at 2.24, 5.1, 7.3c and Annex B.
Unfortunately, this is an IPC operator so, once the initial appeal is rejected (it will be) a secondary appeal to the IAS is an exercise in futility. Others will advise otherwise but personally, I wouldn't bother.
What you want is to see if they have the bottle to take it all the way to the ultimate dispute resolution service, the small claims track in the county court. You would be waiting to see if/when they decide to issue a claim. If they do, that is good and is when you will win this. There is no danger of a CCJ.
In the meantime, they will be sending useless debt collector letters hoping that you are low-hanging fruit on the gullible tree and will capitulate and pay up once they use language that threatens litigation. You want that, they don’t because they know that if it ever got that far, they would get a spanking from a judge.
The choice is yours, appeal as the keeper with the points highlighted above and see it rejected and then do or don’t try an IAS appeal which has a les than 5% chance of being accepted and/or wait for a Letter of Claim (LoC) and an N1SDT claim form from the CNBC.
Edited to add a health warning: There is a minuscule chance that if this ever actually got to a hearing and a judge did not accept your defence, you could be liable for ~£200 in total for the PCN and fixed costs. However, it is extremely unlikely that this would ever get to an actual hearing with the highly likelyhood of the operator having their claim struck out or them discontinuing once they realise you are not gullible and are prepared to take this all the way.
Once they have actually pay a hearing fee, they will abandon and go looking for lower hanging fruit on the gullible tree
