Decision : Closed after initial enquiries
Decision date : 14 May 2026
The Ombudsman's final decision:
Summary: We will not investigate this complaint about Mr X’s council tax liability. This is because he has used his appeal right to the Valuation Tribunal.
The complaint
- Mr X says the Council failed to list his property for council tax for 11 years. It has now issued a backdated bill which is causing him financial hardship.
The Ombudsman’s role and powers
- The Valuation Tribunal deals with appeals against decisions on council tax liability and council tax support or reduction.
- We cannot investigate a complaint if someone has appealed to a tribunal about the same matter. We also cannot investigate a complaint if in doing so we would overlap with the role of a tribunal to decide something which has been or could have been referred to it to resolve using its own powers. (Local Government Act 1974, section 26(6)(a), as amended)
- The courts have said that where someone has sought a remedy by way of proceedings in any court of law, we cannot investigate. This is the case even if the appeal did not or could not provide a complete remedy for all the injustice claimed. (R v The Commissioner for Local Administration ex parte PH (1999) EHCA Civ 916).
How I considered this complaint
- I considered information provided by the complainant. I also considered the Ombudsman’s Assessment Code.
My assessment
- Mr X has appealed to the Valuation Tribunal regarding the Council’s decision to make him liable for council tax. The Tribunal dismissed his appeal.
- We cannot investigate Mr X’s complaint because he has used his appeal rights. The law does not allow us to investigate when the complainant has used their alternative remedy.
Final decision
- We will not investigate Mr X’s complaint because he has used his appeal right to the Tribunal.
