@ishaaq.ar well all London bus lane PCNs can be appealed, and all TFL PCNs can also be appealed, though obviously TFL will never accept anything you say. For now please do the following:
1) Make a representation on
https://tfl.gov.uk/modes/driving/challenge-a-pcn simply stating that the contravention did not occur, and include within the text of the representation an FOI request for the make and model of the camera (do
not email foi@tfl.gov.uk because any such request to that mailbox will be refused).
2) Call TFL tomorrow on 0343 222 3333 and ask for the video, they will put send you a DVD in the post and put the penalty on hold while you wait.
Once you get the notice of rejection let us know and one of us will be able to represent you at the tribunal.
