The top line of the FPN sees, to be to a named person?
There can still be defences to such cases, but often that is a matter of fact and a full (truthful) description of events leading up to the alleged offence, also what may or may not have been admitted at the time (fail to mention now etc.)
Example, defrosting a car on a cold morning may require a period of idling to ensure the car is safe to drive, obviously not applicable here which is why I deliberately used that as an example.
