Thanks for your replies MrChips and cp8759.
The timings were in fact 15:19 and 15:20 so I have responded with the following
The contravention did not occur
Because:
At the time I am supposed to have been in contravention, the restriction did not apply
Your explanation:
Dear London Borough of Lewisham, I challenge liability on the ground that the alleged contravention did not occur. This is because there is a prohibition on entering a box junction if the vehicle cannot clear the box junction without stopping, so the contravention occurs at the point of entry. The video in this case shows the vehicle entered the box junction at 15:19 pm but the penalty charge notice alleges a contravention at 15:20 pm, so while a contravention might have occurred the contravention stated on the face of the notice did not. It follows that the penalty charge must be cancelled. I am not allowed to submit my challenge without ticking one of the reasons presented me, so I have selected " At the time I am supposed to have been in contravention, the restriction did not apply"
By the way MrChips it is indeed at Grove Park Station
