I would refer you to the decision posted on 23 August by stamfordman.
This goes on about this and that and websites and ends:
..The Enforcement Authority have provided an image of a sign on Gillespie Road showing the match day but there is no evidence that the Appellant entered Plimsoll Road from Gillespie Road. I am not satisfied that the Enforcement Authority have provided adequate evidence of the signage relating to this restriction. On that basis[I would add and no other], I allow this appeal.
In other words, allowed only because the adjudicator did not believe that the authority had offered 'adequate evidence of signage' because, in that case, the owner had told them they entered the zone from road A and the authority produced evidence of road B. Whether they were swayed in reaching this decision by other factors, who knows?
In your case, IMO, in order to help you reach a decision pl deal with these questions:
Did the bay in which you were parked stipulate the permit identifier (and therefore zone in which it is located) conditions and restricted hours on 'match days'?
Did you pass a sign into this zone stating that the day on which you parked was a 'match day'?
Did you comply?
Did you consult any other source of information regarding 'match days' before or after you received the PCN?
If before, why?
IMO, there's a defect in the NOR in that it does not inform you correctly of your rights of appeal. These are:
1. That an appeal may be made within the period of 28 days beginning on the date of service. In this case, 'may be made' takes on a legal meaning which is that reps so made and if in correct form MUST be registered by the tribunal AND such registration prevents the council from increasing the penalty and serving a Charge Certificate; and
2. That an appeal may be submitted to the adjudicator after the 28-day period has elapsed who may at their sole discretion register such an appeal with the effect that if the council have not served a CC they may not then do so and if they have then this must be cancelled.
2 is missing.
IMO, 2 is as important as 1 because there can be a whole host of valid reasons why an appeal is not submitted within 28 days e.g. NOR not delivered, recipient not able to deal with matter for reasons beyond their control such as illness, hospital confinement and possibly extended holidays abroad. Add to this the fact that as a matter of regular practice the Tribunal will accept appeals submitted after the end of the 28-day period. Whatever the reason which might apply, it does not lie with the authority to omit bringing this to the attention of the recipient as the law requires.
