'infringement notice' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'average monarch okay' is the wordplay.
'average' becomes 'par' (average score in golf).
'monarch' becomes 'king' (king is a kind of monarch).
'okay' becomes 'fine' (both are ways of saying 'yes').
'par'+'king'+'fine'='PARKING FINE'

'with' acts as a link.
