As above, it is of critical that when the notice to owner is served, the lease company doesn't pay the penalty, or else all appeal rights are lost.
Is it a personal lease or is it leased through your employer? Do you know what process the lease company has in place? Ideally we want liability to be transferred to you so that you can cut them out and we can just deal directly with the council.
As for the contravention, I also think there's another argument: the map tile is
here and it doesn't show the bay being divided into individual spaces, so the parking spaces are not supported by the traffic order and are unlawfully marked. On top of this the order says you must park within the parking
place, which is the whole bay, it doesn't say anything about parking within an individual parking
space, so there's no contravention to begin with.
