The listed statutory grounds of appeal on the PCN are missing these grounds.
(g)the order which is alleged to have been contravened in relation to the vehicle concerned, except where it is an order to which Part 6 of Schedule 9 to the RTRA 1984 applies, is invalid;
(i)the enforcement notice should not have been served because—
(i)the penalty charge has already been paid in full, or
(ii)the penalty charge has been paid, reduced by the amount of any discount set in accordance with Schedule 9 to the TMA 2004, by the applicable date as specified in paragraph 1(3) of Schedule 3 to the 2022 General Regulations.
Also, the bit about being owner of the vehicle is misleading. It says you must supply evidence but the regulations make no such requirement. You must only supply evidence if the information is known to you. The way they have worded it makes it sound like you have no grounds unless you can supply the evidence.
If the PCN does not contain all the info the law requires it to, the PCN is invalid and the penalty charge must be cancelled.
