“ …Accordingly, the objective criteria which form the basis of concepts used in the Sixth Directive form the basis of the concepts which limit the scope of VAT and the right to deduct under sections 1, 4 and 24 of the 1994 Act. Applying the principle in Kittel , the objective criteria are not met if a taxable person knew or should have known that by his purchase he was participating in a transaction connected with fraudulent evasion of VAT. That principle merely requires consideration of whether the objective criteria relevant to those provisions of theVAT Act 1994 are met. It does not require the introduction of any further domestic legislation.”
"the principle of legal certainty provides no warrant for restricting the connection ... to a fraudulent evasion which immediately precedes a trader’s purchase. If the circumstances of that purchase are such that the person knows or should know that his purchase is or will be connected with fraudulent evasion, it cannot matter a jot that is that evasion precedes or follows the purchase. The trader’s knowledge brings him within the category of participant. He is a participant whatever the stage at which the evasion occurs."
“The existence of a rule of national law whereby a court is bound on points of law by the rulings of a superior court cannot on this ground alone deprive the inferior courts of their power, provided for under Aricle 177, to refer questions to the Court of Justice of the European Communities for a preliminary ruling.”
“The essence of contra trading is that transactions in the clean chain are used to mask transactions in the dirty chain. There is no fraud in the clean chain. The dirty chain is where the fraud takes place. Accordingly in order for a trader in the clean chain to know or have the means of knowledge that his transaction is connected with fraud, he must either know or have the means of knowledge that the contra trader is a fraudster; or he must know or have the means of knowledge of the fraud in the dirty chain.”
"In my judgement there are likely to be many cases in which a participant in a sophisticated fraud is shown to have actual or blind-eye knowledge that the transaction in which he is participating is connected with that fraud, without knowing, for example, whether his chain is a clean or dirty chain, whether contra trading is necessarily involved at all, or whether the fraud has at its heart merely a dishonest intention to abscond without paying tax, or that intention plus one or more multifarious means of achieving a cover-up while the absconding takes place. "
“As the Chancellor pertinently asked in Blue Sphere… how can a trader who is not part of a conspiracy know of a fraud before it happens?” and then later [17]: “…since the dirty chain was created after the clean chain actual knowledge and conspiracy are likely to be interchangeable concepts.”
“In the same way, a 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.”
“A person who knows that a transaction in which he participates is connected with fraudulent tax evasion is a participant in that fraud. That person has a dishonest state of mind. By contrast a person who merely ought to have known of the relevant connection is not dishonest, but has a state of mind broadly equivalent to negligence.”
