I have requested the footway parking resolution but this could take a month or so to come back.
In the meantime, make a basic challenge:
Dear London Borough of Barking and Dagenham,
I challenge liability for PCN BZ61315872 on the grounds that the alleged contravention did not occur. Footway parking is permitted on Cartwright Road and there are no signs indicating footway parking is only permitted in marked bays. There is also no rule of law that says footway parking must be within marked bays, indeed there are many areas of London where footway parking is permitted even though there are no bays at all.
Where footway parking is only permitted in marked bays, the council is required to install upright signs compiling to diagrams 667.1 or 668.1 with an auxiliary plate stating "in marked bays", there are no such signs on Cartwright Road.
If footway parking is only permitted in marked bays, the authority has failed to comply with its duties under section 15(5) of the Greater London Council (General Powers) Act 1974, as a consequence of which the alleged contravention did not occur.
Should the council not be willing to accept this representation, please would you provide a copy of the footway parking resolution for this road.
In any even I further contend that my vehicle was merely stopped and was not parked within the meaning of the legislation. I stopped my car where I did in order to collect my 2 month old baby and grandmother who is disabled (and a blue badge holder). As soon as I walked in I grabbed baby things, opened the door and the civil enforcement officer was standing in front of my car. I asked him not to issue a penalty charge notice at which point he started printing it.
Owing to the brevity of the stop for an amount of time that was purely nominal, I content that my vehicle was not parked, and I note the legislation uses the work "parked" not the word "stopped" (this is not a red route).
It follows that the penalty charge should be cancelled in any event.
Yours faithfully
