The role of the Ombudsman is primarily to investigate service provision, not internal issues. Their guidance states:
"I'm not happy with a service provided by my parish council. Can the Ombudsman help me?
In most cases, no. The Local Government Act 1974 (S34(1)) defines the authorities that we may investigate. Parish and town councils are not included in this definition."
"Can the Ombudsman look at a complaint about a parish or town councillor?
No. A complaint about the conduct of a parish or town councillor should be made to the council itself. If you are not satisfied with the outcome, a local Standards Committee (usually run by whichever local council collects your council tax) may consider your complaint."
The remit of the Monitoring Officer is very limited and most issues fall outside their powers. Even in the most serious cases, unless Police involvement becomes necessary, they can do little more than write a strongly-worded letter.
