Pl post your formal reps.
Why has the authority apparently copied the NOR to a third party?
IMO, when the time comes, register your appeal:
1. Contravention did not occur;
2. Procedural impropriety.
1. Their photographic evidence does not support their claim that 'there are Yellow Signs displayed informing motorists of the suspension in operation.' is manifestly wrong. Their website, to which the NOR directs you, has two photos, neither of which shows the wording on the sign, in fact it shows they show that the sign was incomplete and damaged.
2. The NOR does not include the mandatory info regsrding the power of the adjudicator to register an appeal beyond the 28-day period. IMO, this is as integral and important as giving the 28-day period...which in any event has been given incorrectly: it's no later than the period of 28-days beginning on, NOT from because 'from' excludes the trigger event, in this case the day of service and has the effect of stating that you have the right to appeal on 'day 29' but you don't.
