I remember this clearly where as I was driving down Ripple Road (Barking), a car had pulled out from the petrol station hence I used the bus lane oppose to carrying out an emergency brake.
It doesn't really come across like that in the video:
As Hippocrates has identified, vague locus is a good starting point, so I suggest you draft a challenge based on that and put it on here for review. As far as I can see there are at least 11 bus stops on Ripple Road but it's worth double-checking.
In the meantime I'll find out the make and model of the camera, they might not have a valid certificate for it.
It's worth adding that officers from this authority are unlikely in the extreme to turn up to a contested hearing, and if you require them to attend and they don't you win by default, so it's probably worth taking this all the way.
