Make the same representation again.
Thanks I'll write the same again as per below,
Dear London Borough of Redbridge,
The alleged contravention did not occur. The PCN was issued for parking on the footway, however footway parking has been allowed on this road since 2014. The footway parking resolution disapplies the footway parking ban from the entire road, and any signs that suggest otherwise are simply incorrect. I refer you to the decision in Himat Kotecha v London Borough of Redbridge (2210061465, 18 March 2021), which was based on essentially identical facts.
As such the alleged contravention did not occur and the PCN must be cancelled.
Yours faithfully,
