“4. In contra-trading there are, in its simplest theoretical form, two chains of transactions. First, the "dirty chain," in which there is a defaulting trader ("defaulting trader" for short), comprising A (the defaulting trader) who is the importer of goods into the UK, who sells them to B (the buffer company), who sells them to C who exports the goods, and is thus in a VAT reclaim position. (For simplicity we shall use the expressions import and export for intra-Community trade, acknowledging that these are not the proper labels.) Secondly, the "clean chain," in which there are no missing traders, comprising C, who is this time the importer of other goods, who sells to D, who sells to E, the exporter (the Appellant in this appeal is in the position of E in relation to the three alleged contra-trading deals). The effect of the clean chain is that the net input tax position of C in the dirty chain is cancelled by output VAT in the clean chain. There is no direct financial benefit to C in this as C has paid the input tax to B, and therefore C could be in league with the defaulting trader, or could be a trader who is controlled (possibly without knowing it) by a "puppet master" to enter into the cancelling transactions to disguise A's involvement a fraud, or a trader who happens to carry out both import and export transactions unconnected with any fraud,. The effect of the contra-trades is that C does not excite Customs' attention as it is not applying for a repayment; the non-payment of tax by A is less noticeable since without a return Customs do not know how much tax A owes. The input tax reclaim that C had in the dirty chain has moved to E who is at the end of a clean chain. The only way for Customs to refuse repayment of E's input tax is to show that E knew or ought to have known of A's fraud in a completely different chain, and of C's involvement in the fraud. 5. The nature of contra-trading is easy to state in the above way but the problem in real life is that there is no logical connection between the clean and dirty chains. First, the VAT accounting periods for C and E will not coincide; E may be on a monthly accounting period as it is a habitual exporter, but C may be on a three-monthly period, and C need only arrange that the net tax is nil during that three-monthly period by entering into transactions after E's transactions. Secondly, the goods dealt in may be different in the two chains. Thirdly, for a particular C there may be many different equivalents to A and E, and for a particular E there may be many equivalents of C, each with more than one equivalents to A. Fourthly, C may not have deliberately entered into imports in the clean chain in order to cancel the input in the dirty chain; C may merely be both an importer and an exporter whose outputs in relation to the former happen roughly to cancel its inputs in relation to the latter. Fifthly, there may be many Bs and Ds in between the importer and exporters. 6. The fraud in a simple MTIC fraud is that the defaulting trader always intends to default. It will normally be the case that he defaults later than the dates the deals in the chains are executed because he fails to pay the tax due for the period in which the deals occur. One of the problems is that C, the exporter in a simple MTIC fraud, is always separated from the defaulting importer by one or more Bs and may not know of the existence of A. If C enters into a deal that is too good to be true it can be said that he ought to know of the fraud even though he does not know of A's identity. In a contra-trading fraud the question is whether E knows or ought to have known that C entered into the clean chain transactions to cover A's intention to default. Again the problem is that E may be separated from C by one or more Ds (although in this case C, the alleged contra-trader sells directly to E, the Appellant).”
“It must also be borne in mind that a finding of abusive practice must not lead to a penalty, for which a clear and unambiguous legal basis would be necessary, but rather to an obligation to repay, simply as a consequence of that finding, which rendered undue all or part of the deductions of input VAT.”
“46 So far as concerns the treatment of VAT that has been improperly invoiced because there is no taxable transaction, it follows from Directive 2006/112 that the two traders involved are not necessarily treated identically in so far as the issuer of the invoice has not corrected it … 47 On the one hand, the issuer of an invoice is liable to pay the VAT entered on that invoice even if there is no taxable transaction, in accordance with Article 203 of Directive 2006/112. On the other hand, exercise of the right of deduction by the recipient of an invoice is limited solely to tax corresponding to a transaction subject to VAT, in accordance with Articles 63 and 167 of that directive. 48 In such a situation, compliance with the principle of fiscal neutrality is ensured by the possibility, to be provided for by the Member States and noted in paragraph 37 above, of correcting any tax improperly invoiced where the issuer of the invoice shows that he acted in good faith or where he has, in sufficient time, wholly eliminated the risk of any loss of tax revenue. ... 50 It follows that Articles 167 and 168(a) of Directive 2006/112 and the principle of fiscal neutrality do not preclude the recipient of an invoice from being refused deduction of input VAT because there is no taxable transaction, even though, in the tax adjustment notice addressed to the issuer of the invoice, the VAT declared by the latter was not adjusted.”
“58 … it is true that preventing possible tax evasion, avoidance and abuse is an objective recognised and encouraged by Directive 2006/112 and European Union law cannot be relied on for fraudulent or abusive ends (see, inter alia,Case C-255/02 Halifax and Others[2006] ECR I-1609 , paragraphs 68 and 71; Joined Cases C-80/11 and C-142/11 Mahagében and Dávid[2012] ECR I-0000 , paragraph 41; and Bonik , paragraphs 35 and 36). 59 It is therefore incumbent upon the national authorities and courts to refuse the right of deduction where it is established, on the basis of objective evidence, that that right is being relied on for fraudulent or abusive ends (see, to that effect, Joined Cases C-439/04 and C-440/04 Kittel and Recolta Recycling[2006] ECR I-6161 , paragraph 55; Mahagében and Dávid , paragraph 42; and Bonik , paragraph 37). 60 Nevertheless, according to case-law that is also well-established, it is incompatible with the rules governing the right of deduction under Directive 2006/112 to impose a penalty, in the form of refusal of that right, on a taxable person who did not know, and could not have known, that the transaction concerned was connected with fraud committed by the supplier, or that another transaction forming part of the chain of supply prior or subsequent to the transaction carried out by the taxable person was vitiated by VAT fraud (see, inter alia, Joined Cases C-354/03, C-355/03 and C-484/03 Optigen and Others[2006] ECR I-483 , paragraphs 52 and 55; Kittel and Recolta Recycling , paragraphs 45, 46 and 60; Mahagében and Dávid , paragraph 47; and Bonik , paragraph 41).”
“The Kittel principle is not concerned with penalty. It is true that there may well be no correlation between the amount of output tax of which the fraudulent trader has defrauded HMRC and the amount of input tax which another trader has been denied. But the principle is concerned with identifying the objective criteria which must be met before the right to deduct input tax arises. Those criteria are not met, as I have emphasised, where the trader is regarded as a participant in the fraud. No penalty is imposed; his transaction falls outwith the scope of VAT and, accordingly, he is denied the right to deduct input tax by reason of his participation.”
