“firstly, what the ECJ meant by “should have known” and secondly, as to the extent of the knowledge which it must be established that the taxpayer had or ought to have had: is it sufficient that the taxpayer knew or should have known that it was more likely than not that his purchase was connected to fraud or must it be established that he knew or should have known that the transactions in which he was involved were connected to fraud?”
“If a taxpayer has the means at his disposal of knowing that by his purchase he is participating in a transaction connected with fraudulent evasion of VAT he loses his right to deduct, not as a penalty for negligence, but because the objective criteria for the scope of that right are not met. It profits nothing to contend that, in domestic law, complicity in fraud denotes a more culpable state of mind than carelessness, in the light of the principle in Kittel. A trader who fails to deploy means of knowledge available to him does not satisfy the objective criteria which must be met before his right to deduct arises.”
“Perhaps of greater weight is the challenge based, in Mobilx and BSG, on HMRC's denial of the right to deduct on the grounds that the trader knew or should have known that it was more likely than not that transactions were connected to fraud. The question arises in those appeals as to whether that is sufficient or whether, as the Chancellor concluded in BSG, the right to deduct input tax may only be denied where the trader knows or should have known that the transaction was connected to fraud (see judgment, § 52). In short, does a trader lose his entitlement to deduct if he knew or should have known of a risk that his transaction was connected to fraudulent evasion of VAT? HMRC contends that the right to deduct may be denied if the trader merely knew or should have known that it was more likely than not that by his purchase he was participating in such a transaction. It contends that if it was necessary to show more than appreciation of a risk then the Court's decision in Kittel would not represent a development of the law and would fail to achieve the objective, recognised in the Sixth Directive, to which the Court referred at § 54. As I have already indicated, the mere existence of that objective and the principle that Community law cannot be relied upon for fraudulent ends (e.g., Fini H § 32) does not provide any justification for a general principle that any transaction connected with fraud is vitiated. Such an approach was rejected in Optigen. If HMRC was right and it was sufficient to show that the trader should have known that he was running a risk that his purchase was connected with fraud, the principle of legal certainty would, in my view, be infringed. A trader who knows or could have known no more than that there was a risk of fraud will find it difficult to gauge the extent of the risk; nor will he be able to foresee whether the circumstances are such that it will be asserted against him that the risk of fraud was so great that he should not have entered into the transaction. In short, he will not be in a position to know before he enters into the transaction that, if he does so, he will not be entitled to deduct input VAT. The principle of legal certainty will be infringed. It must be remembered that the approach of the court in Kittel was to enlarge the category of participants. A trader who should have known that he was running the risk that by his purchase he might be taking part in a transaction connected with fraudulent evasion of VAT, cannot be regarded as a participant in that fraud. The highest it could be put is that he was running the risk that he might be a participant. That is not the approach of the Court in Kittel, nor is it the language it used. In those circumstances, I am of the view that it must be established that the trader knew or should have known that by his purchase he was taking part in such a transaction.”
“The test in Kittel is simple and should not be over-refined. It embraces not only those who know of the connection but those who "should have known". Thus it includes those who should have known from the circumstances which surround their transactions that they were connected to fraudulent evasion. If a trader should have known that the only reasonable explanation for the transaction in which he was involved was that it was connected with fraud and if it turns out that the transaction was connected with fraudulent evasion of VAT then he should have known of that fact. He may properly be regarded as a participant for the reasons explained in Kittel. The true principle to be derived from Kittel does not extend to circumstances in which a taxable person should have known that by his purchase it was more likely than not that his transaction was connected with fraudulent evasion. But a trader may be regarded as a participant where he should have known that the only reasonable explanation for the circumstances in which his purchase took place was that it was a transaction connected with such fraudulent evasion.”
“A trader who decides to participate in a transaction connected to fraudulent evasion, despite knowledge of that connection, is making an informed choice; he knows where he stands and knows before he enters into the transaction that if found out, he will not be entitled to deduct input tax. The extension of that principle to a taxable person who has the means of knowledge but chooses not to deploy it, similarly, does not infringe that principle. If he has the means of knowledge available and chooses not to deploy it he knows that, if found out, he will not be entitled to deduct. If he chooses to ignore obvious inferences from the facts and circumstances in which he has been trading, he will not be entitled to deduct. The principle of legal certainty provides no warrant for restricting the connection, which must be established, to a fraudulent evasion which immediately precedes a trader's purchase. If the circumstances of that purchase are such that a person knows or should know that his purchase is or will be connected with fraudulent evasion, it cannot matter a jot that that evasion precedes or follows that purchase. That trader's knowledge brings him within the category of participant. He is a participant whatever the stage at which the evasion occurs.”
“As I indicated in relation to the BSG appeal, Tribunals should not unduly focus on the question whether a trader has acted with due diligence. Even if a trader has asked appropriate questions, he is not entitled to ignore the circumstances in which his transactions take place if the only reasonable explanation for them is that his transactions have been or will be connected to fraud. The danger in focussing on the question of due diligence is that it may deflect a Tribunal from asking the essential question posed in Kittel, namely, whether the trader should have known that by his purchase he was taking part in a transaction connected with fraudulent evasion of VAT. The circumstances may well establish that he was.”
“… there is no necessary connection between the seriousness of an allegation and the improbability that it has taken place. The test is the balance of probabilities, nothing more and nothing less.”
