Nice and simple:
Dear Liverpool City Council,
The alleged contravention did not occur. While I accept road markings do not need to be kept in pristine condition, the road markings on this occasion have all but vanished and give the impression of a restriction that is no longer in force.
As the council has defaulted on its duties under regulation 18(1)(b) of The Local Authorities' Traffic Orders (Procedure) (England and Wales) Regulations 1996, the contravention did not occur and the penalty charge must be cancelled.
Yours faithfully,
Send it online and keep a screenshot of the confirmation screen.
