“…a Tribunal or court might sist proceedings against the wish of a party if it considered that a decision in another court would be of material assistance in resolving the issues before the Tribunal or court in question and that it was expedient to do so.”
“Articles 167, 178, 220, and 273 of Directive 2006/112 and Article 17, 18(1) and 22(8) of the Sixth VAT Directive must be interpreted in conformity with the principles of proportionality, neutrality, and legal certainty, such that they do not permit national legislation or administrative practice which, as regards “necessary precautions” makes the right to deduction conditional upon the recipient of the invoice proving that the company drawing up the invoice respected its legal obligations and in that regard establishes an objective responsibility on the part of the recipient of the invoice. Nor can the right of deduction of VAT be affected by the fact that the taxpayer knew or could have known that in the supply chain in which his own transaction, not itself tainted with fraud, was carried out another transaction before or after that taxpayer’s transaction, amounted to VAT fraud or another violation. On the other hand, once it is established in the light of objective elements that the delivery is made to a taxpayer who knew or ought to have known that in making the purchase he was participating in an operation that was part of VAT fraud, it is that that point possible to refuse the right of deduction.”
“[56] 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. [57] That is because in such a situation the taxable person aids the perpetrators of the fraud and becomes their accomplice.”
