GSV July 2024 shows 2 parking places in this length of street, one for loading the other for Disabled BB holders. The latter is internally divided into 3 spaces. Numbering from the loading bay, the OP was parked in the first and a single traffic sign (Disabled BB holders 24/7) was situated at the kerb between the second and third.
The CEO's photos show a 'suspension' sign on the traffic sign post suspending use of all 3 spaces from Oct 2024-28 Feb. 2025 for 'works'.
The PCN was issued on 25 Feb.
The OP wrote: 'I saw nothing to indicate the bay was suspended (I'm not local) but took a picture of the car/bay. Forgot to take a picture of the disabled parking sign. Would be helpful to know what I should write in the appeal.
OP, does this mean that you did not look for and read the traffic sign but simply assumed that your length of stay would be such that you could not possibly be in contravention of the regular restriction which you inferred from the marking alone?
This happens regularly on this forum, but usually with Res permit holders whose parking spaces extend to perhaps 100m in length and as frequent flyers they don't check signs every time they park.
For me, the most important parts of your account are that:
The parking place was suspended in its entirety for 4 months for 'works', that it was small and that you managed to park easily;
Nothing on the ground was occurring in your or the other parking spaces to cause you to think anything other than the spaces were available for use;
The CEO's photos confirm that no 'works' vehicles were parked behind you neither can any 'works' paraphernalia be seen.
IMO, the likely scenario is that the 'works' had ceased but the council had not removed the suspension sign because the applicant had paid for a further 3 days.
This defence has succeeded with councils and adjudicators i.e. once the reason for the suspension has ceased then the suspension itself cannot be enforced.
Wait for other views and pl answer tne queries above.
