Free Traffic Legal Advice

Newbie here,
Just received a PCN for driving westbound on Leahurst rd in Hither Green. A notoriuos junction it seems.
I came in from Hither Green Lane down Ennersdale rd to pick up my partner at Hither Green station at midnight after the trains were diverted. There was nobody on the streets, I wasn't aware of any driving restrictions, in fact there aren't any restrictions coming in from that direction but going back the same way, there are.
Going back, I needless to say, didn't notice anything, it looks like every other suburban street in the area with cars parked on both sides of the street and it being very late and dark, nothing stood out as unusual and why would anyone assume you can't drive back the way you came unless there was a 'no entry' sign or '1 way street' sign. The sign only appears once you are actually upon it, so there is nowhere to turn around and go back.
I'm not sure if the sign has been changed since previous cases have been appealed so unsure of the probability of winning an appeal?
Any advice much appreciated.

Get and post the video

As I recall we've seen this one several times, and there were some wins at London Tribunals, centreing on adequacy of signage.

These are the signs you passed on your outward journey, (GSV June 2025).

But unfortunately GSV is only up to 2018 once those signs are passed. They are, no doubt, the usual Flying Motorbike signs. A location like this really does need advance warning signs, so to give best advice, we need to see what signs are on approach and also what the actual signs are. The video doesn't show them properly as one can see, in fact, you could use that as a point in your reps.

Have added pics from today of the junction. Seems the signs are there, I ignored them assuming they were width restrictions and was paying attention to the road and the upcoming left turn and speaking to my partner who I'd just picked up. I guess its a fruitless exercise trying to win this one?

Well, it's certainly not a slam-dunk win situation.  There may be a 'technical' appeal based on council mismanagement of the enforcement process, but I'll leave that to Hippocrates. Note that such appeals are inevitably dealt with at London Tribunals with the full PCN penalty in play.
