I'm not sure how your Monitoring Officer deals with alleged criminal breaches, however, I know in our area, all complaints have to go to the MO first, they then decide if there is sufficient evidence to pass to the Police, and then they will be guided by the principle authority. This is not a cop-out, it is because the standards required by a criminal court are much higher than as if it were a civil matter
I know that if a complaint is made directly to the Police, they refer the complaint back to the MO before they will even look at anything, especially as already said the standards required by a criminal court are much higher than as if it were a civil matter.
Another consideration is who foots the legal costs, I believe the MO will ultimately pass these back to the Parish, so it may mean that you, as an individual, may have to explain to the electorate why they have suddenly been hit with a legal bill for several thousands of pounds, that even didn't get into court! A bill that would possibly fail the public interest test in the first place.
