This is the formal challenge which is made to the Valuation Tribunal against the decision of the Valuation Office Agency, or the council, not to give the person the change they have asked for. For council tax banding, appeals can be made by the taxpayer where they receive a decision from the Valuation Office Agency that they are not happy with. For council tax liability appeals, a taxpayer must firstly have raised the issue in dispute with the council in writing and if, within certain time limits, a decision is received which they are not satisfied with, or the council does not respond, an appeal can be made by the taxpayer directly to the Tribunal. In rating, appeals are sent to the Tribunal by the Valuation Office Agency valuation officer, if he is unable to agree to a proposal a ratepayer has made within a certain time limit.
