// Section 106 of the Local Government Finance Act 1992 makes it an offence for a councillor in council tax arrears (with at least two months unpaid bills) to vote at a meeting of the council, a committee or of the council’s executive where financial matters relating to council tax are being considered. It is also an offence if any such councillor present, who is aware of the arrears, fails to disclose that they are in arrears of council tax. //
All votes at full council meetings in which these councillors participated must be invalid, or at least could be contested. If they voted on finacial matters, such as setting budgets, or indeed approving the Council Tax rate, are potentially not legal.
