@Aubama draft representation:
Dear London Borough of Lewisham,
I challenge liability on the grounds that the alleged contravention did not occur, as footway parking is permitted on Galahad Road and there are no signs indicating such parking is permitted in marked bays only. If you are minded to refuse this representation, I ask that you provide the footway parking resolution duly enacted under section 15(4) of the Greater London Council (General Powers) Act 1974, so that I may confirm whether the bays are correctly marked.
Yours faithfully,
Don't forget to take a timed / dated screenshot of the confirmation page.
