“… a taxpayer cannot complain of unfairness, merely because the commissioners decide to perform their statutory duties including their duties under section 460 to make an assessment and to enforce a liability to tax. The commissioners may decide to abstain from exercising their powers and performing their duties on grounds of unfairness but the commissioners themselves must bear in mind that their primary duty is to collect, not to forgive taxes. And if the commissioners decide to proceed the court cannot in the absence of exceptional circumstances decide to be unfair that which the commissioners by taking action against the taxpayer have determined to be fair. The commissioners possess unique knowledge of fiscal practices and policy. The commissioners are inhibited from presenting full reasons to the court for their decisions because of the duty of confidentiality owed by the commissioners to each and every taxpayer. The court can only intervene by judicial review to direct the commissioners to abstain from performing their statutory duties or from exercising their statutory powers if the court is satisfied that “the unfairness” of which the applicant complains renders the insistence by the commissioners on performing their duties or exercising their powers an abuse of power by the commissioners. … ” [1985] 1 AC at p. 864 “… In principle I see no reason why the appellant should not be entitled to judicial review of a decision taken by the commissioners if the decision is unfair to the appellant because the conduct of the commissioners is equivalent to a breach of contract or a breach of representation. Such a decision falls within the ambit of an abuse of power for which in the present case judicial review is the sole remedy and an appropriate remedy. …” [1985] 1 AC at p. 866H-867A Mr. Singh further relied on the following passage in the judgment of Judge J (as he then was) in R v CIR ex p. MFK Underwriting Agencies Ltd (1989) 62 T.C. 607 at p. 647 E-G. “There is a detailed procedure for resolving disputes between the Inland Revenue and the taxpayer and if necessary for bringing such disputes to the courts for decision. In addition, however, as the Inland Revenue is an “administrative body with statutory duties” (per Lord Wilberforce in Regina v Commissioners of Inland Revenue ex parteNational Federation of Self Employed at page 632) it is not immune from an order for judicial review. Since the decision in the House of Lords in Regina v Commissioners of Inland Revenue ex partePreston[1985] AC 835 the principle has been established that acts which are an abuse of the Inland Revenue’s powers or acts done outside those powers may be subject to judicial review. Abuse of power may take the form of unfairness. This is not mere “unfairness” in the general sense. Even if “unfair”, efficient performance of the statutory obligations imposed on the Inland Revenue will not, of itself, amount to an abuse of power”
“(10) On an objective but untechnical view, it would be hard to regard Unilever as owing£17m additional tax to the Revenue. If this tax is due it can fairly be regarded as an adventitious windfall, accruing to the Revenue through the understandable error of an honest and compliant taxpayer, cleared over many years by the Revenue.”

“ … 8.1 In the appeal against the assessments for the Earlier Years the Defendants did not contend nor was it found by the Special Commissioner that the Claimant had procured the transfer of the Old Minority Shares to International Holdings; 8.2 the amount of income tax chargeable in the event that section 741 did not apply was agreed by the parties and was not determined by the Special Commissioner; 8.3 such assessments were contrary to the Defendants’ then unpublished practice and/or understanding of the law to the extent that the assessments sought to charge the Claimant to income tax on income which was attributable to the Old Minority Shares unless it could be established that the Claimant had procured the transfer of the Old Minority Shares by the Old Minority Shareholders. 8.4 the Officers of the Inland Revenue having conduct of the appeal on behalf of the Defendants either knew or, with the exercise of reasonable care, should have known: 8.4.1 the facts at 8.3 above; and/or 8.4.2 the Defendants were not alleging that the Claimant had procured the transfer of the Old Minority Shares; 8.4.3. the Claimant and his advisers were or were unlikely to be aware of such internal practice and, in the absence of a finding by the Special Commissioner that the Claimant had procured the transfer of the Old Minority Shares, would be acting under a mistake in agreeing that an amount of income tax calculated by reference to dividends paid in respect of the Old Minority Shares would be chargeable in the event that Section 741 did not apply; 8.5. In the Second Decision the Deputy Special Commissioner, Dr Avery-Jones C.B.E, (a) expressly found that the Claimant had not procured the transfer of the Old Minority Shares, and (b) was correct to do so.”
