Not that urgent because there's a glaring procedural error with the PCN, which states:
'Parked in a parking place or area not
designed for that class of vehicle'
The mandated contravention description is:
Parked in a parking place or area not designated for that class of vehicleHigher Suffix required to fully describe contraventionSetting aside for one moment that they've used the term 'designed' for 'designated', you might wonder why a motorist is entitled to know the suffix in order to fully describe the contravention.
The answer is that there is a smorgasbord of bays which may be designated as being reserved for specific classes of vehicle. Here are some with their suffix letter/number:
a) permit holder only electric vehicle charging bay
c) buses only
g) motorcycle bay
k) ambulance bay
w) e-scooter bay
y) electric solo motorcycle bay
0) local buses / trams only
1) electric vehicles bay
2) goods vehicle loading bays
3) bicycle bay
7) taxis only

zero emission capable taxis only
9) electric vehicle car club bay
I would make representations on the basis that there has been a procedural impropriety on the part of the authority. This arises because the PCN does not state correct grounds, contrary to the requirements of para. 2(c) of Schedule 2 to the General Regulations, which require a PCN to state:
c)the grounds on which the civil enforcement officer issuing the notice believes that a penalty charge is payable,
I refer you to the PCN which gives the following contravention description:
'Parked in a parking place or area not
designed for that class of vehicle'
I have highlighted the terminological error which you will no doubt report to your IT colleagues.
The other material defect is that the description omits the 'higher suffix' which as you will know is required in order to, as the London Councils' published list of contraventions states, 'fully describe ]the] contravention'.
These are objective facts which cannot be finessed or denied by the authority.
The PCN fails to comply with mandatory requirements and therefore must be cancelled.
