“8. … With the failure of the community charge, the 1992 Act, which introduced the council tax for the purpose of taxation of domestic property, returned to the basic scheme of valuing individual properties by a common yardstick, in this case their capital value. Council tax in England is paid according to which of eight valuation bands, fixed by the statute, an individual dwelling falls into. Thus, in essence, council tax is payable by the resident of a chargeable dwelling on an annual basis and the amount of tax is based on the valuation band against which the dwelling is entered on the valuation list. That value and thus the appropriate valuation band are determined by listing officers in accordance with valuation principles prescribed by the 1992 Act and its Regulations. 9. For the purpose of council tax, the valuation had to be done by reference to two dates,1 April 1991 and1 April 1993 (the ‘1991 date’ and the ‘1993 date’ respectively). The yardstick for valuation was fixed according to the open market price at which the dwelling might reasonably have been expected to have sold at the 1991 date; but the size, layout and character of the dwelling and the physical state of its locality, on the basis of which the 1991 date valuation had to be fixed, was to be taken as at the date of its actual valuation, which (broadly speaking) was in the run-up to and conventionally as at the 1993 date. In terms of the statutory language, the 1991 date valuation had to be made on the assumption that dwelling and locality were as they were at the date of actual valuation. Certain other assumptions also applied, such as that the dwelling was in a reasonable state of repair. The valuation list was then compiled on1 April 1993 and came into effect on that day. The general effect of these provisions is that inspection and valuation are all done, within a tight time regime, in relation to the physical configuration of the dwelling and the physical state of the locality, but by reference to certain conventional yardsticks, such as a common assumption that the dwelling is in a reasonable state of repair, and, importantly, a common ‘bible’ of market values as of a single day,1 April 1991 .”
“(1) Subject to regulation 7, for the purposes of valuations under section 21 (valuations for purposes of lists) of the [1992 Act], the value of any dwelling shall be taken to be the amount which, on the assumptions mentioned in paragraphs (2) and (3) below, the dwelling might reasonably have been expected to realise if it had been sold in the open market by a willing vendor on1st April 1991 .”
“(2) The regulations may include provision that where a listing officer intends to alter the list with a view to its being accurately maintained, he shall not alter it unless prescribed conditions (as to notice or otherwise) are fulfilled.”
“(b) the listing officer is satisfied that – (i) a different valuation band should have been determined by him as applicable to the dwelling; …”
“(1) No alteration shall be made of a valuation band shown in a list as applicable to any dwelling unless – … (b) the LO is satisfied that – (i) a different valuation band should have been determined by the LO as applicable to the dwelling; …”
“(1) No alteration shall be made of a valuation band shown in a list as applicable to any dwelling unless – (a) since the valuation band was first shown in the list as applicable to the dwelling – (i) … there has been a material increase in the value of the dwelling and a relevant transaction has been subsequently carried out in relation to the whole or any part of it; …” (a) since the valuation band was first shown in the list as applicable to the dwelling – (i) … there has been a material increase in the value of the dwelling and a relevant transaction has been subsequently carried out in relation to the whole or any part of it; …”
“a transfer on sale of the fee simple, a grant of a lease for a term of seven years or more or a transfer on sale of such a lease.”
“whether an error had occurred in April 1993 when the appeal property was originally placed in the council tax list as a band C property.”
“10. The clerk explained that, in an appeal of this nature, the correct legal test to apply is, firstly, does the LO have power to increase the assessment and then, secondly, was there evidence from the time the appeal property was initially placed in the council tax list at band C [to show that this was] a mistake. As the LO had determined the earlier entry in the list to be an error, the clerk advised the panel that the only evidence admissible was the evidence that was available to the LO at the time, when the alleged error occurred, which in this case was1 April 1993 . 11. The panel also had regard to the High Court decision of Zeynab Adam v Listing Officer[2014] EWHC 1110 (Admin) , together with decisions of the former President of the Tribunal, Professor G Zellick QC, in Ward v Coll (LO) and Martin v Coll (LO). The judgment in Zeynab Adam gave authority to the LO to correct an entry in the Valuation List that resulted from a mistake. 12. Having regard to the wording of [regulation 3(1)(b)(i) of the 2009 Regulations], together with the authorities quoted, the panel accepted the clerk’s advice that, when dealing with appeals of this nature, regard must only be had to evidence that was available to the LO at the time when the alleged error occurred.”
“13. The panel found that the LO representative had not been able to provide evidence to justify her claim that the initial entry in the list resulted from a mistake. No evidence was produced to show what evidence / information was used when the appeal property was initially placed into the council tax list.”
“Since all rateable values in a rating list must be assessed at a common valuation date, the ‘tone of the list’ for a particular category of hereditament is the general level of value for that type of hereditament at that date. Assessments under appeal will carry less weight than assessments which are settled in the absence of an appeal or following determination of an appeal. The weight to be attached to comparable assessments increases over time.”
“”[I]t is settled law that assessments of comparable hereditaments are admissible as evidence of value … and there are three stages leading to the establishment of tone of the list. At first, when the list is put on deposit, the assessments carry little weight: they are opinions of value by the valuation officer, as yet unchallenged and untested by negotiation and determination. As time passes more and more assessments are agreed or determined by valuation tribunals or this tribunal. Finally, a stage is reached when enough assessments have been settled or are unchallenged to establish a patter of established values, a ‘tone of the list’.”
“18. Therefore, the panel made a finding of fact, that the LO had not made a mistake in April 1993, as such, the panel allowed the appeal.”
“The simple fact is that the regulatory regime permits past errors to be corrected for the future. … Historical errors may be corrected whatever the reason for the error and providing the listing officer is satisfied that the band should have been different.”
“(2) The burden on the listing officer to show that a mistake was made at the time should be scrutinised by the tribunal with considerable intensity before endorsing the alteration.”
“If the question goes to arbitration, the arbitrator’s duty is to determine the amount of compensation payable. In order to enable him to come to a just and true conclusion it is his duty, I think, to avail himself of all information at hand at the time of making his award which may be laid before him. Why should he listen to conjecture on a matter which has become an accomplished fact? Why should he guess when he can calculate? With the light before him, why should he shut his eyes and grope in the dark?”
