"The decisions relied on the registration of the buyer of the business [NNS]. That registration was fundamentally flawed, and consequently that of the Appellant [Withington], on the following grounds: 1. The original registration of the buyer NNS made on8 February 2018 was found to be invalid 2. That original registration of NNS although invalid, was amended and is under review 3. HMRC's estimated turnover of NNS calculated from the purchases of supplies, invigilations and seasonal fluctuations was statistically incompetent 4. The argument is that because the buyer (NNS) was registrable the Appellant was registrable and because the Appellant was registrable the buyer was registrable (TOGC) ('Transfer of Going Concern'). This argument is circulatory (sic) and either unlawful or unreasonable in the sense of being illogical."
"What the words 'best of their judgment' envisage, in my view, is that the Commissioners will fairly consider all material placed before them and, on that material, come to a decision which is one which is reasonable and not arbitrary as to the amount of tax which is due. As long as there is some material on which the Commissioners can reasonably act then they are not required to carry out investigations which may or may not result in further material being placed before them"
"The element of guess-work and the almost unavoidable inaccuracy in a properly made 'best of judgment' assessment, as the cases have established, do not serve to displace the validity of the assessments, which are prima facie right and remain right until the taxpayer shows (i) that they are wrong and also (ii) shows positively what corrections should be made in order to make the assessments right or more nearly right."
