Are you asking if you are liable?
Ok. so what is your question about this please?
not sure what you mean?
If the lease requires that you display the permit and you did not then you are in breach.
it isn't an offence. It is a breach of contract. Nevertheless you are in breach.
Whether you could argue there was no loss is another matter.
On your specific point though, there isn't a defence arising if the lease requires that you actually display the permit.
Can I clarify anything for you?
No, not really.
Usually the permit system requires that they must be displayed. Otherwise there is no point in a permit system.
No. I am really sorry but I am not going to be able to tell you this is a ground of appeal.
There is a permit system under the contract. Not displaying does not comply.
Well, it depends.
I wouldn't pay personally. I would take the risk to see whether they sue.
Your question wasn't that though. Your original question was whether or not this was a defence and it is not.
No. If they have a contract they can enforce it.
No. It just means they have issued a notice.
Until they actually issue a summons you can't be sure they intend to sue.
On the basis of the information you are providing you do not have a positive defence.
