They rejected this, here is the NOR.


Here is some of the photo evidence:



They note on the NOR that my vehicle is not signalling, but they can't see the left hand side indicator from the photos or CCTV and whilst it is true that the taxi doesn't stop in the bus lane (from memory of viewing the CCTV) I was already in the box when it passed, having had to stop.
My understanding is that the contravention occurs if the presence of stationary vehicles causes me to stop in the box, but as the bus lane was clear when I entered the box and had it not been for the taxi I would have moved to the bus lane. Where do I stand on choosing not to move after the taxi had gone?
Any thoughts or advice welcome.
