Incandescent the restriction is actually 7 am to 7 pm, there is no restriction at all outside of those hours (confirmed by the white bay markings, which can only be used where stopping is permitted at all times when the red route is in operation.
@Avrumy here you go:
Dear Transport for London,
The alleged contravention did not occur. Stopping is permitted at this location, it might be that a PCN could have been issued for code 30 "Parked for longer than permitted" but of course that would be a lower level contravention.
I refer you to the tribunal decision in Spencer Weems v Transport for London (2180331206, 22 September 2018).
It follows that the alleged contravention did not occur, and the penalty demanded exceeds the amount duly set by law.
Yours faithfully,
Make representations via the TfL website and make sure to keep a screenshot of the confirmation page.
