“There are three stages leading to the establishment of tone of the list. At first, when a new rating list is put on deposit, assessments will carry relatively little weight: they are opinions of value by the valuation officer, as yet unchallenged and untested by negotiation. Over time assessments will be challenged and agreed or determined by a VT or this Tribunal or accepted by lack of challenge. Finally, a stage will be reached when enough assessments have been agreed or determined or are unchallenged to establish a pattern of values, a tone of the list. The list is then said to have settled: rents will be largely subsumed into assessments. At this stage rating surveyors will have little regard to rents and pay considerable attention to assessments. The position at any time regarding the tone of the list is a question of fact. When an assessment is challenged before a tribunal the correct time for deciding whether the tone of the list has been established is immediately before the hearing. The weight to be given to comparable assessments as evidence of value will depend on the circumstances in each case. These may indicate that little or no weight should be given to comparable assessments, eg where acceptance of value is more acceptance of rate liability or where a body of settlement evidence rests on a single agreed assessment.”
“…There is no time pressure on a ratepayer to check and challenge an assessment and the importance of making early proposals under previous lists, and thus the earlier establishment of a tone, no longer exists. Mr Watson has explained that several of the comparable assessments will need to be revisited. I do not consider that Mr Watson has impugned the compiled list in saying this; the VO has a statutory duty to maintain an accurate list and if the measurement and/or description of a hereditament is inaccurate then it is incumbent on the VO to correct it once he becomes aware of it, even in the absence of a material change of circumstances.”
