“The traders contend that to enlarge the category of participants in the fraud to those who should have known that by their purchase they were taking part in a transaction connected with fraud is to impose a new accessory liability for fraud which does not exist in domestic law; it imposes, so they assert, a negligent standard for fraud by the back door”
“The denial of the right to deduct in this case stems from principles which apply throughout the Community in respect of what is said to be reliance on Community law for fraudulent ends. It can be no objection to that approach to Community law that in purely domestic circumstances a trader might not be regarded as an accessory to fraud” 141.The Mobilx judgement provided elucidation of the “should have known” test: At paragraph 51 of the judgment it was stated: “The [ECJ] must have intended the phrase “knew or should have known” which it employs in paras 59 and 61 of Kittel to have the same meaning as the phrase “knowing or having the means of knowing” which it used in Optigen (Para 55)”
“The trader is 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 connected to fraud”
“ 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”
“The ultimate question is not whether the trader exercised due diligence but rather whether he should have known that the only reasonable explanation for the circumstances in which his transaction took place was that it was connected to fraudulent evasion of VAT”
“It is plain that if HMRC wishes to assert that a trader’s state of knowledge was such that his purchase is outwith the scope of the right to deduct it must prove that assertion”
“… 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”
“The balance of probability standard means that a court is satisfied an event occurred if the court considers that, on the evidence, the occurrence of the event was more likely than not. When assessing the probabilities the court will have in mind as a factor, to whatever extent is appropriate in the particular case, that the more serious the allegation the less likely it is that the event occurred and, hence, the stronger should be the evidence before the court concludes that the allegation is established on the balance of probability. Fraud is usually less likely than negligence. Deliberate physical injury is usually less likely than accidental physical injury. A step-father is usually less likely to have repeatedly raped and had non-consensual oral sex with his under age stepdaughter than on some occasion to have lost his temper and slapped her. Built into the preponderance of probability standard is a generous degree of flexibility in respect of the seriousness of the allegation. "Although the result is much the same, this does not mean that where a serious allegation is in issue the standard of proof required is higher. It means only that the inherent probability or improbability of an event is itself a matter to be taken into account when weighing the probabilities and deciding whether, on balance, the event occurred. The more improbable the event, the stronger must be the evidence that it did occur before, on the balance of probability, its occurrence will be established.”
“the more serious the allegation the more cogent the evidence needed to prove it.”
“They are not there to punish or deter anyone. The consequences of breaking a core order are not penal. Care proceedings are there to protect the child from harm. The consequences for the child of getting it wrong are equally serious either way”
“Neither the seriousness of the allegation nor the seriousness of the consequences should make any difference to the standard of proof to be applied in determining the facts. The inherent probabilities are simply something to be taken into account, where relevant, in deciding where the truth lies”
“ As to the seriousness of the allegation , there is no logical or necessary connection between seriousness and probability. Some seriously harmful behaviour, such as murder, is sufficiently rare to be inherently improbable in most circumstances. Even then there are circumstances, such as a body with its throat cut and no weapon to hand, where it is not at all improbable. Other seriously harmful behaviour, such as alcohol or drug abuse, is regrettably all too common and not at all improbable . Nor are serious allegations made in a vacuum. Consider the famous example of the animal seen in Regent's Park. If it is seen outside the zoo on a stretch of greensward regularly used for walking dogs, then of course it is more likely to be a dog than a lion. If it is seen in the zoo next to the lions' enclosure when the door is open, then it may well be more likely to be a lion than a dog.”
"It would be absurd to suggest that the tribunal must in all cases assume that serious conduct is unlikely to have occurred. In many cases, the other evidence will show that it was all too likely. If, for example, it is clear that a child was assaulted by one or other of two people, it would make no sense to start one's reasoning by saying that assaulting children is a serious matter and therefore neither of them is likely to have done so. The fact is that one of them did and the question for the tribunal is simply whether it is more probable that one rather than the other was the perpetrator."
