Contravention 14 May
NOR 29 Aug, served 2 Sept.
OP, is this your vehicle or is it leased/hired?
It's my vehicle but just under a HP finance agreement.
OP, let's stay with terms which we know pl.
Who is the registered keeper?
Whatever the answer, then IMO the PCN is probably VOID. You need to deal with the PCN's validity before worrying about the contravention and detailed wording.
If you are the keeper then the PCN was served late.
If whoever else is the keeper, then IMO you cannot be held to be the owner because you have not indicated that the vehicle is subject to a hiring agreement of less than 6 months nor a lease.
