“136...Any fact-finding exercise requires the court to marshal all of the evidence, including the witness testimony, the documents and the uncontested events, and to test each strand of evidence against the others, and against the inherent probabilities and motives of the actors. It is an iterative or reflexive process…”
“…However, I do consider that the letters of 2003 need to be looked at more closely. Although counsel for Revenue & Customs very properly avoided the any assertion that the letter from the inland revenue dated the11 March 2003 was a forgery, nevertheless he pointed out there were one or two oddities about the letter. I am not in a jurisdiction which can determine those oddities. … What this letter does point to, if I take it at its face value is that Revenue & Customs had in their possession in 2003, in plenty of time, the three returns on which they have based their determinations within the five year period… I cannot determine whether or not the letter of11 March 2003 is genuine But I think I have to take it for the purposes of today at face value. That may well not be the case further down for another tribunal but at face value the Revenue & Customs had the returns in their hands well within the time limit. On that basis, the reliance by Revenue & Customs on the disputed determinations is simply not right and the bankruptcy petition is effectively based on a nullity. I do not know what the debt would be if those tax returns were properly assessed and it may well reduce the debt considerably, if not wipe it out altogether”
“The subjective test 25. It is clear that before an officer makes a discovery assessment, he must have formed a certain state of mind. The question raised on this appeal is: what must the officer think or believe? The three judges in the Divisional Court in R v Kensington Income Tax Commissioners all agreed that it was not necessary for the officer to reach a conclusion which was justified by sufficient legal evidence. However, when describing what was required for this purpose, the three judges expressed themselves in different terms which do not appear to us to describe the same test. 26. Any test which is devised as to the necessary subjective belief on the part of the officer must be a practical and workable test. The expression of the test has to recognise that at the time when an officer thinks that it is desirable to make a discovery assessment, the officer may appreciate that in certain respects he may not be in possession of all of the relevant facts. Further, the officer may foresee that a discovery assessment might give rise to questions of law some of which might not be straightforward. 27. In Revenue and Customs Commissioners v Lansdowne Partners Ltd Partnership, when considering the meaning of “be aware of” for the purposes of s 29(5), it was said that “awareness” was a matter of perception not conclusion and that it was possible to say that an officer was “aware of” something even when he could not at that stage resolve points of law and even though he was not then aware of all of the facts which might turn out to be relevant. Although the word “discover” and the phrase “be aware of” cannot be treated as synonyms, we consider that if it is possible to be aware of something when one does not know all of the relevant facts and one cannot foretell how relevant points of law will be resolved, it cannot be said to be premature for an officer to “discover” that same something even when he knows he is not in possession of all of the relevant facts and does not know how relevant points of law will be resolved. 28. In Sanderson, Patten LJ described the power under section 29(1) in this way: “The exercise of the section 29(1) power is made by a real officer who is required to come to a conclusion about a possible insufficiency based on all the available information at the time when the discovery assessment is made”
“The officer must believe that the information available to him points in the direction of there being an insufficiency of tax”
“230. As we have seen from Anderson, there are two requirements here. The first is that the officer must decide the amount which needs to be assessed to make good to the Crown the loss of tax and that decision must meet an objective criterion. Although this is a phrase which comes from the VAT legislation not TMA, which does not in terms impose a “best judgment” requirement, by way of shorthand we describe an assessment which meets this test as a “best judgment” assessment. 231. It is common ground that we should look to distil the objective requirement from Johnson v Scott, 52 TC 383 (“Johnson”), and Bi-flex Carbbean Ltd v The Board of Inland Revenue (“Bi-flex”), (1990) 63 TC 515. 232. Johnson considered estimated assessments in respect of alleged understated trading profits and in respect of income from interest and property. The taxpayer submitted that the inferences which the Inspector submitted to the Commissioners they ought to make on the facts were not, to use his phrase, "legal evidence" upon which they were entitled to act. Walton J observed that “the real point is that such inferences (which [the taxpayer’s counsel] would undoubtedly dismiss as mere guesses) are, of necessity, all that the Crown can lay before Commissioners in such a case as the present.”
“244. Looking at the extracts from Bi-flex and the earlier decisions referred to by the Privy Council in Bi-flex, set out above and in particular the passages we have underlined, we learn the following about the objective requirement: (1) The requirement for objectivity does not preclude the officer making a guess which turns out to be wrong - N Ltd); (2) The requirement of objectivity does preclude an officer from acting dishonestly or vindictively or capriciously. The officer must exercise judgment and make what he honestly believes to be a fair and proper estimate; there must necessarily be guesswork, but it must be honest guess-work - Badridas; (3) The contrast is between a guess honestly made on such materials as are available, which meets the objective standard, and a spurious estimate or guess in which all elements of judgment are missing - Argosy; (4) There is no need to carry out an investigation unless there is no material on which the officer can reasonably base an assessment – Van Boeckel; (5) A large element of guess-work/estimation may be required where only sparse material is available; Bi-flex. 245. These points are entirely consistent with the conclusion we drew from Johnson, that it is perfectly permissible for an officer to estimate the amount of tax due by making reasonable/fair inferences, but what an inspector cannot do is make “wild or extravagant claims”. 246. These conclusions inevitably mean that a taxpayer has a high hurdle to jump before they can impugn an assessment on the basis that it does not meet the objective/best judgment requirement. The reason for that is, as this Tribunal (Judge Frost and Mr Farooq) observed in Wyatt v HMRC,[2024] UKFTT 00867 (TC) (“Wyatt”), at [26], that an overassessment can be dealt with through the normal appeal process and Parliament is unlikely to have wished to encourage collateral attacks on assessments beyond the normal appeal process. A similar point was made by the Court of Appeal in relation to challenges to VAT best judgment assessments in CCE v Pegasus Birds Ltd,[2004] EWCA Civ 1015 (“Pegasus Birds”) at [38]. In that case it was held that that an assessment would only fail the “best judgment” test if there had been no honest and genuine attempt to make a reasoned assessment of the VAT payable. Even in such a case, the Court of Appeal was not persuaded that the correct response was to set aside the whole assessment.”
