PCN for CPZ contravention 01 - Parked in a restricted street during prescribed hours L.B. Hillingdon

One could think that the driver knows the area intimately and that there's no confusion over the meaning of signs and restrictions.

One could.
 
Or one could think that the driver had always thought the SYL restrictions were as per the signs on the lamp posts.

It's a surprising own-goal by the council but the 28 day period to pay or appeal is stated as being from the date of the notice, rather than the date of service of the notice. Truncating the statutory period like this is accepted by all adjudicators as a procedural impropriety, so I'd say you have very strong grounds for carrying on.

I'll drop you an PM with your options for representation.

Hillingdon are currently not fighting many tribunal cases

..and 'will send you a charge certificate'.

Obviously and off day at Hillingdon.

DNC'ed.
