Parish Councils main governing principles are set out in the Local Government Act 1972 & in particular in Schedule 12 of that Act.  This Act sets out some of the minimum requirements for Councils in relation to meetings, conduct & documentation, such as:-

Councils must meet a minimum of 4 times/year & must keep minutes of their meetings,

They must have their accounts audited in accordance with this & subsequent legislation,

Meetings must be publicly advertised in advance within the area served by the Council and

Councillors must, on taking office formally agree to be bound by a new Code of Conduct.

Local Council meetings must be open to the Press & Public, but meetings can be closed to
both if in the Councils opinion‘publicity would be prejudicial to the public interest.
