"Where it appears to the Commissioners requisite to do so for the protection of the revenue they may require a taxable person, as a condition of his supplying goods or services under a taxable supply, to give security or further security of such amount and in such manner as they may determine, for the payment of any tax which is or may become due from him."
"The Commissioners ... have noted the VAT record of the above business and other businesses in which your directors Mr. John Davison and Mr. Peter Newton were involved and for the protection of the revenue and in pursuance of their powers under Schedule 7, paragraph 5(2) of the [1983 Act] they require you, as a condition of your supplying goods or services under a taxable supply within the meaning assigned to it by Section 2(1) of the said Act, to give security to them by guarantee or by a cash deposit in the sum of£355,900.00 ... for the payment of any Value Added Tax which is or may become due from you.
"(a) Firstly the new company John Dee Limited has no connection with the old John Dee Group Limited apart from two of its directors were former directors of the John Dee Group Limited. Apart from this the new company was purchased from the Official Administrative Receiver which was a very small part of the old Group and the part purchased is profitable, this can be seen from the enclosed audited accounts. (b) Secondly the two directors mentioned in your letter do not own the Company in fact there has been a substantial third party investment ... (c) The payments made to the Customs & Excise for John Dee Ltd. since the commencement of business on11 March 1991 have been made as per the terms and conditions laid down by H.M. Customs & Excise. (d) As I am sure you are fully aware to ask for a security of such a large amount would only create further problems to a new company trying to survive during these difficult economic times."
"Where an appeal under this section is against a decision of the Commissioners which depended upon a prior decision taken by them in relation to the appellant, the fact that the prior decision is not within subsection (1) above shall not prevent the tribunal from allowing the appeal on the ground that it would have allowed an appeal against the prior decision."
"... The tribunal shall not allow the appeal or, as the case may be, so much of it as relates to that determination unless it considers that the determination is one which it was unreasonable to make or which it would have been unreasonable to make if information brought to the attention of the tribunal that could not have been brought to the attention of the Commissioners had been available to be taken into account when the determination was made."
"Where there is an appeal against a decision to make such direction as is mentioned in subsection (1) (hh) above, the tribunal shall not allow the appeal unless it considers that the Commissioners could not reasonably have been satisfied as to [certain matters set out in paragraphs (2) and (4) of paragraph 1A]."
"Conduct falling within subsection (1) above shall not give rise to liability to a penalty under this section if (a) the person concerned satisfies the Commissioners, or on appeal, a Value Added Tax Tribunal that there is a reasonable excuse for the conduct
"The Tribunal ... should restrict itself, on the hearing of an appeal, to deciding whether the taxpayer company had established that the decision arrived at by the Commissioners was unreasonable, or (as the chairman of the Tribunal did in this case) whether the decision had been arrived at by taking into account matters which were not relevant, or by ignoring matters which were relevant."
"The first matter in this appeal is to establish the nature of the appeal to the Value Added Tax Tribunal. Is it a re-hearing whereby the Tribunal can review the discretion of the Commissioners and alter it or come to a different conclusion if it so desires, or does the Tribunal on the other hand exercise only a supervisory jurisdiction, limiting its decision to one based on Wednesbury principles?
"It seems to me that it is not tenable to argue that the Commissioners must always have regard to the financial position of the taxpayer when considering whether or not to require security However, [the evidence on behalf of the Commissioners] indicated that it was the practice of [the department responsible for security] never to ask taxpayers to provide financial or other information.
"The jurisdiction of the courts to entertain applications for judicial review is a supervisory jurisdiction of an essentially practical nature designed to protect the citizen from breaches by decision makers of their public law duties. That there will be such a breach if the decision maker takes account of irrelevant matters or fails to take account of relevant matters, in the sense that his decision is affected thereby, is not in doubt. But, if his decision is not affected thereby, there is no reason why the jurisdiction should be exercised and every reason why it should not."
"I find that it is most likely that, if the Commissioners had had regard to [the doubt expressed in the report to the Licensing Authority] their concern for the protection of the revenue would probably have been fortified. …

"The function of the appellate court is initially one of review only. It may set aside the judge's exercise of his discretion on the ground that it was based upon a misunderstanding of the law or the evidence before him or upon an inference that particular facts existed or did not exist ... There may also be occasional cases where even though no erroneous assumption of law or fact can be identified the judge's decision ... is so aberrant that it must be set aside upon the grounds that no reasonable judge regardful of his duty to act judicially could have reached it. It is only if and after the appellate court has reached the conclusion that the judge's exercise of his discretion must be set aside for one or other of these reasons, that it becomes entitled to exercise an original discretion of its own."
"What sort of appeal is it? Is the Recorder to look at the reasons of the committee and to give effect to them unless they are so lacking in grammar or so obviously wrong on the face of them that certiorari would lie?
"I find that it is most likely that, if the Commissioners had had regard to paragraph (iii) of the conclusion to Mr. Ross' report, their concern for the protection of the revenue would probably have been fortified."
