Free Traffic Legal Advice

Yeah, I'm very disappointed that they didn't respond to my actual points!
Do you think I have a valid case? Do I have a chance of winning this?

Hi all,

I'd appreciate some opinions before deciding whether to risk the discount and continue this appeal.

I received a Lewisham PCN (Code 62A – parked with one or more wheels on or over a footpath) on Creekside, SE8 outside approximately 71–73 Creekside, just north of Berthon Street.

I accept that my vehicle was partly on the footway. My appeal is not that the contravention didn't physically occur.

Instead, my argument is that Lewisham may not have had the legal authority to enforce at this location.

The evidence I've found so far is:

Lewisham's online borough boundary map places the location on the Greenwich side of the borough boundary.
Greenwich's online borough boundary map also places the location within Greenwich.
Greenwich's Road Register contains USRN 20800409 (CREEKSIDE), maintained by Greenwich, with coordinates 537544,177641 to 537569,177520, which appear to include the location of where my vehicle was.
FindMyStreet shows both the Greenwich USRN and a Lewisham USRN for Creekside. Both appear to use the same centreline geometry, making it unclear whether responsibility is split by side of the road or whether there is another explanation.
Lewisham's Highway Register contains the entry: "Creekside | Bdy | 609 | Boundary Rd – maintained by Lewisham south of southern kerb line Berthon Street."

(My vehicle was north of Berthon Street, so the Highway Register seems to indicate its not within their jurisdiction??)

I submitted an informal challenge arguing that Lewisham had not established jurisdiction at that location. The rejection did not address that point and instead consisted almost entirely of a standard explanation that footway parking is prohibited in London.

My questions are:

Is this a legally viable ground of appeal, assuming the footway falls within Greenwich's highway?
Does the Highway Register or USRN information have any real evidential value in determining the enforcement authority?
Has anyone come across similar cases involving boundary roads and highway authority?

I'm also planning to contact both Lewisham and Greenwich Highways to ask them to confirm which authority is responsible for the footway adjacent to 71–73 Creekside and whether they can provide a highway extent plan.

Any thoughts would be greatly appreciated!!!
