"The fraud is plainly committed, if the participants in such chain are dishonest, at the stage of the missing trader , although the loss may not crystallise until the Revenue has to pay out in full in respect of the return filed by the exporter." (Emphasis in original)
"… on the assumed facts … Evolution is 'a taxable person who knew … that by his purchase, he was taking part in a transaction connected with fraudulent evasion of VAT'. In those circumstances, I am satisfied that the Revenue would have the right to refuse to pay the input claimed, and my concluded view is the same as was the untutored response of Charles J in Megantic : and the same as the provisional view of Mr Bishopp in Calltell (see [2007] UKVAT V20266 , para 18) that: '18. … if the Respondents can show that the transactions were what they claim them to be … they have at least an arguable case that a trader who, knowingly or with means of knowledge, engages in conduct designed to conceal, or avoid the consequences of discovery of, a fraud should be in no better position than the perpetrator of the fraud.'" 101. In the case of contra-trading, therefore, the fraudulent conduct extends to conduct "designed" to conceal or avoid the discovery of a fraud. In other words the cover up is part of an overarching scheme, and is part of an overall fraud. But whether this is a correct description of the overall fraud depends on the facts. Underlying Mr Anderson's description of the fraud is the assumption that there is an overarching scheme. But whether there is such a scheme is for the Tribunal to decide. Mr Anderson's formulation assumes that which it is necessary for HMRC to prove. 102. In my judgment in a case of alleged contra-trading, where the taxable person claiming repayment of input tax is not himself a dishonest co-conspirator, there are two potential frauds: i) The dishonest failure to account for VAT by the defaulter or missing trader in the dirty chain; and ii) The dishonest cover-up of that fraud by the contra-trader. 103. Thus it must be established that the taxable person knew or should have known of a connection between his own transaction and at least one of those frauds. I do not consider that it is necessary that he knew or should have known of a connection between his own transaction and both of these frauds. If he knows or should have known that the contra-trader is engaging in fraudulent conduct and deals with him, he takes the risk of participating in a fraud, the precise details of which he does not and cannot know. As Millett J put it in Agip (Africa) Ltd v Jackson[1990] Ch. 265 , 295 (in the context of dishonest assistance in a breach of trust): "
" whether or not Evolution knew of the precise nature of the defaulter chain or of the goods purportedly dealt with in that chain or the identities of the participants in that chain, Evolution knew of the fraudulent aim of Blackstar in acquiring, through the off-set on the contra-trading transaction, the opportunity to receive, by such off-set, VAT which it would not be able to recover direct from the Revenue." (Emphasis added)
"It is difficult to see how a trader, entering into a chain of transactions in which every trader accounts correctly for VAT (and which is not tainted for some other reason) could have the means of knowing that it is a device for concealing, or avoiding the consequences of discovery of, another, fraudulent, chain of transactions. Nevertheless it is, we think, possible that a trader could have the means of knowing that, by his participation, he is assisting a fraud. Much will depend on the facts, but an obvious example might be the offer of an easy purchase and sale generating a conspicuously generous profit for no evident reason. A trader receiving such an offer would be well advised to ask why it had been made; if he did not he would be likely to fail the test set out at paragraph 51 of the judgment in Kittel ."
