Pl don't make the mistake of exporting your situation to the CEO's knowledge and reasoning. Just make reps on the basis of what you've said.
Dear Sir,
PCN **********
I refer to the above issued to my* car on **** for parking in a disabled bay without displaying a valid blue badge.
The badge is issued by Torfaen Council to my son who has held it for 18 years. The one displayed was out of date having expired on ***. A renewal request was submitted online on ***, the web page carrying the following, rather ominous, messages:
A renewal request may not be submitted more than 4 weeks in advance of expiry;
Renewal could take up to *** weeks;
An out-of-date badge is invalid.
I do not criticise the CEO for issuing the PCN because they didn't know the particular circumstances which applied. However, I hope that now that the authority is aware of the full picture they will exercise discretion and cancel the PCN.
