“12 Clearly the purpose intended to be achieved by this elaborate, long established statutory scheme would be defeated if it were open to a taxpayer to leave undisturbed an assessment with which he is dissatisfied and adopt the expedient of applying to the High Court for a declaration of how much tax he owes and, if he has already paid the tax, an order for repayment of the amount he claims was wrongly assessed. In substance, although not in form, that would be an appeal against an assessment. In such a case the effect of the relief sought in the High Court, if granted, would be to negative an assessment otherwise than in accordance with the statutory code. Thus in such a case the High Court proceedings will be struck out as an abuse of the court's process. The proceedings would be an abuse because the dispute presented to the court for decision would be a dispute Parliament has assigned for resolution exclusively to a specialist tribunal. The dissatisfied taxpayer should have recourse to the appeal procedure provided by Parliament. He should follow the statutory route. 13 I question whether in this straightforward type of case the court has any real discretion to exercise. Rather, the conclusion that the proceedings are an abuse follows automatically once the court is satisfied the taxpayer's court claim is an indirect way of seeking to achieve the same result as it would be open to the taxpayer to achieve directly by appealing to the appeal commissioners. The taxpayer must use the remedies provided by the tax legislation…”
“In my view these claims in the High Court are prima facie a misuse of the court's process. These claims cover the same ground in all respects as the appeals pending before the appeal commissioners. The remedy sought is co-extensive with adjudicating upon existing, open assessments. The essence of the High Court claims is that these assessments were wrong, that the court should so hold, and that the court should itself calculate the amounts which ought to have been assessed and order repayment of the overpaid excess. There could hardly be a more obvious example of seeking to sidestep the statutory procedure.”
“the general principle embodied in tax law before self-assessment, that any dispute with the revenue about an individual's liability to income tax or a company's liability to corporation tax is to be determined in the first instance by the general commissioners or the special commissioners.”
“This elaborate deeming provision has the effect (so far as it applies) that, where under section 380(1)(b) loss relief is claimed on income in the preceding year, the claim nonetheless ‘relates’ to the later year (para 2(3)). The amount of the claim is computed using the formula in paragraph 2(4), based on the income in the previous year; but it does not affect the tax position in the earlier year (para 2(3)). It gives rise to a ‘free-standing credit’ (in the Revenue's language) which can be used in any of the ways set out in paragraph 2(6).”
