“60 VAT evasion: conduct involving dishonesty (1) In any case where— (a) for the purpose of evading VAT, a person does any act or omits to take any action, and (b) his conduct involves dishonesty (whether or not it is such as to give rise to criminal liability), he shall be liable, … to a penalty equal to the amount of VAT evaded or, as the case may be, sought to be evaded by his conduct. (2) The reference in subsection (1)(a) above to evading VAT includes a reference to obtaining any of the following sums— (a) … ; (b) a VAT credit; … in circumstances where the person concerned is not entitled to that sum. (3) The reference in subsection (1) above to the amount of VAT evaded or sought to be evaded by a person’s conduct shall be construed— (a) in relation to VAT itself or a VAT credit as a reference to the aggregate of the amount (if any) falsely claimed by way of credit for input tax and the amount (if any) by which output tax was falsely understated; (b) … … (7) On an appeal against an assessment to a penalty under this section, the burden of proof as to the matters specified in subsection (1)(a) and (b) above shall lie upon the Commissioners.” (a) for the purpose of evading VAT, a person does any act or omits to take any action, and (b) his conduct involves dishonesty (whether or not it is such as to give rise to criminal liability), (a) … ; (b) a VAT credit; (a) in relation to VAT itself or a VAT credit as a reference to the aggregate of the amount (if any) falsely claimed by way of credit for input tax and the amount (if any) by which output tax was falsely understated; (b) … … (7) On an appeal against an assessment to a penalty under this section, the burden of proof as to the matters specified in subsection (1)(a) and (b) above shall lie upon the Commissioners.”
“(2) Subject to the provisions of this section, he is entitled at the end of each prescribed accounting period to credit for so much of his input tax as is allowable under section 26, and then to deduct that amount from any output tax that is due from him. (3) If either no output tax is due at the end of the period, or the amount of the credit exceeds that of the output tax then, … the amount of the credit or, as the case may be, the amount of the excess shall be paid to the taxable person by the Commissioners; and an amount which is due under this subsection is referred to in this Act as a “VAT credit”.” subsection is referred to in this Act as a “VAT credit”.”
“(1) The amount of input tax for which a taxable person is entitled to credit at the end of any period shall be so much of the input tax for the period (that is input tax on supplies, acquisitions and importations in the period) as is allowable by or under regulations as being attributable to supplies within subsection (2) below. (2) The supplies within this subsection are the following supplies made or to be made by the taxable person in the course or furtherance of his business— (a) taxable supplies; (b) supplies outside the United Kingdom which would be taxable supplies if made in the United Kingdom; (c) such other supplies outside the United Kingdom and such exempt supplies as the Treasury may by order specify for the purposes of this subsection.”
“53. By contrast, the objective criteria which form the basis of the concepts of ‘supply of goods effected by a taxable person acting as such’ and ‘economic activity’ are not met where the tax is evaded by the taxable person himself (see Halifax plc v Customs and Excise Comrs (Case C-255/02 )[2006] STC 919 ,[2006] Ch 387 , para 59). 54. As the court has already observed, preventing tax evasion, avoidance and abuse is an objective recognised and encouraged by the Sixth Directive (see Joined Cases C-487/01 and C-7/02 Gemeente Leusden and Holin Groep[2004] ECR I-5337 , paragraph 76). Community law cannot be relied on for abusive or fraudulent ends (see, inter alia,Case C-367/96 Kefalas and Others[1998] ECR I-2843 , paragraph 20;Case C-373/97 Diamantis[2000] ECR I-1705 , paragraph 33; andCase C-32/03 Fini H[2005] ECR I-1599 , paragraph 32). 55. Where the tax authorities find that the right to deduct has been exercised fraudulently, they are permitted to claim repayment of the deducted sums retroactively (see, inter alia, Case 268/83 Rompelman [1985] ECR 655, paragraph 24;Case C-110/94 INZO[1996] ECR I-857 , paragraph 24; and Gabalfrisa, paragraph 46). It is a matter for the national court to refuse to allow the right to deduct where it is established, on the basis of objective evidence, that that right is being relied on for fraudulent ends (see Fini H, paragraph 34). 56. In the same way, the taxable person who knew or should have known that, by his purchase, he was taking part in a transaction connected with fraudulent evasion of VAT must, for the purposes of the Sixth Directive, be regarded as a participant in that fraud, irrespective of whether or not he profited by the resale of the goods. 57. That is because in such a situation the taxable person aids the perpetrators of the fraud and becomes their accomplice. 58. In addition, such an interpretation, by making it more difficult to carry out fraudulent transactions, is apt to prevent them. 59. Therefore, it is for the referring court to refuse entitlement to the right to deduct where it is ascertained, having regard to objective factors, that the taxable person knew or should have known that, by his purchase, he was participating in a transaction connected with fraudulent evasion of VAT, and to do so even where the transaction in question meets the objective criteria which form the basis of the concepts of ‘supply of goods effected by a taxable person acting as such’ and ‘economic activity’.”
“… in the sphere of VAT an abusive practice can be found to exist only if, first, the transactions concerned, notwithstanding formal application of the conditions laid down by the relevant provisions of the Sixth Directive and the national legislation transposing it, result in the accrual of the tax advantage the grant of which would be contrary to the purpose of those provisions. Secondly, it must also be apparent from a number of objective factors that the essential aim of the transactions concerned is to obtain a tax advantage. … the prohibition of abuse is not relevant where the economic activity carried out may have some explanation other than the mere attainment of tax advantages.”
“56. Contrary to the assertions of Emsland-Stärke, the obligation to repay refunds received in the event that the two constituent elements of an abuse are established would not breach the principle of lawfulness. The obligation to repay is not a penalty for which a clear and unambiguous legal basis would be necessary but simply the consequence of a finding that the conditions required to obtain the advantage derived from the Community rules were created artificially, thereby rendering the refunds granted undue payments and thus justifying the obligation to repay them.”
“30. … By its rejection of the United Kingdom argument, the Court [in Optigen] made clear that the reason why fraud vitiates a transaction is not because it makes the transaction unlawful but rather because where a person commits fraud he will not be able to establish that the objective criteria which determine the scope of VAT and the right to deduct have been met.”
“41 The interpretation which the Court, in the exercise of the jurisdiction conferred upon it by Article 267 TFEU, gives to EU law clarifies and defines, where necessary, the meaning and scope of that law as it must be, or ought to have been, understood and applied from the date of its entry into force. It follows that, unless there are truly exceptional circumstances, which is not however claimed to be the case here, EU law as thus interpreted must be applied by the courts even to legal relationships which arose and were established before the judgment ruling on the request for interpretation, provided that in other respects the conditions for bringing a dispute relating to the application of that law before the courts having jurisdiction are satisfied (…).”
“Principles of legality and proportionality of criminal offences and penalties 1. No one shall be held guilty of any criminal offence on account of any act or omission which did not constitute a criminal offence under national law or international law at the time when it was committed. Nor shall a heavier penalty be imposed than that which was applicable at the time the criminal offence was committed. If, subsequent to the commission of a criminal offence, the law provides for a lighter penalty, that penalty shall be applicable. 2. This Article shall not prejudice the trial and punishment of any person for any act or omission which, at the time when it was committed, was criminal according to the general principles recognised by the community of nations. 3. The severity of penalties must not be disproportionate to the criminal offence.”
“24. It is true that the national court must apply its domestic law as far as possible in the light of the wording and the purpose of the Directive so as to achieve the result it seeks to achieve … However, that obligation on the national court to refer to the content of the Directive when interpreting the relevant rules of its national law is not unlimited, particularly where such interpretation would have the effect, on the basis of the Directive and independently of legislation adopted for its implementation, of determining or aggravating the liability in criminal law of persons who act in contravention of its provisions (see in particular Case 80/86 Kolpinghuis Nijmegen [1987] ECR 3969, para 13). 25. More specifically, in a case such as that in the main proceedings, which concerns the extent of liability in criminal law arising under legislation adopted for the specific purpose of implementing a directive, the principle that a provision of the criminal law may not be applied extensively to the detriment of the defendant, which is the corollary of the principle of legality in relation to crime and punishment and more generally of the principle of legal certainty, precludes bringing criminal proceedings in respect of conduct not clearly defined as culpable by law. That principle, which is one of the general legal principles underlying the constitutional traditions common to the Member States, has also been enshrined in various international treaties, in particular inArticle 7 of the Convention for the Protection of Human Rights and Fundamental Freedoms (see, inter alia, the judgments of the European Court of Human Rights in Kokkinakis v Greece,25 May 1993 , Series A, No 260-A, paragraph 52, and in S. W. v United Kingdom and C. R. v United Kingdom,22 November 1995 , Series A, No 335-B, paragraph 35, and No 335-C, paragraph 33). 26. The national court must therefore ensure that that principle is observed when interpreting, in the light of the wording and the purpose of the Directive, the national legislation adopted in order to implement it.”
“58. The legal basis for the imposition of legal sanctions must thus be clear and unequivocal, that is to say, unambiguous. No doubt a criminal provision also requires interpretation by the courts, but they are not permitted to fill any lacunae in the definitions of offences by resorting to an extensive interpretation. … 63. The principle of legal certainty, when understood in this way, precludes resorting to a Community directive in order to extend the definition of an offence, to the disadvantage of the accused, from situations different from those which strictly match the definition of the punishable acts given by national criminal law.”
