In those circumstances, the Krajský soud v Praze (Regional Court, Prague) decided to stay the proceedings and to refer the following questions to the Court for a preliminary ruling: ‘(1) Must any taxable person be regarded as a taxable person within the meaning of Article 138(2)(b) of [the VAT Directive]? If not, to which taxable persons does that provision apply? (2) If the Court’s answer is that Article 138(2)(b) of the VAT Directive applies to a situation such as that in the main proceedings (that is, the acquirer of the products is a taxable person registered for tax), must that provision be interpreted as meaning that, where the dispatch or transport of those products takes place in accordance with the relevant provisions of [Directive 2008/118], a supply connected with a procedure under [Directive 2008/118] must be regarded as a supply entitled to exemption under that provision, even though the conditions for exemption under Article 138(1) of the VAT Directive are not otherwise satisfied, having regard to the assignment of the transport of goods to another transaction? (3) If the Court’s answer is that Article 138(2)(b) of the VAT Directive does not apply to a situation such as that in the main proceedings, is the fact that the goods are transported under an excise duty suspension arrangement decisive for deciding the question of which of several successive supplies a transport is to be ascribed to for the purposes of the right to exemption from VAT under Article 138(1) of the VAT Directive? (4) Is “the right to dispose of the goods as owner” within the meaning of the VAT Directive acquired by a taxable person who buys goods from another taxable person directly for a specific customer in order to fulfil an already existing order (identifying the type of goods, the quantity, place of origin and time of delivery) where he or she does not physically handle the goods him or herself since, in the context of concluding the contract of sale, his or her buyer agrees to arrange transport of the goods from their point of origin, so that he or she will only provide access to the requested goods via his or her suppliers and communicate the information necessary for acceptance of the goods (on his or her own behalf or on behalf of his or her sub-suppliers in the chain), and his or her profit from the transaction is the difference between the buying-in price and the selling price of such goods without the cost of transporting the goods being invoiced in the chain? (5) Does [Directive 2008/118] establish (for example, in Article 4(1), Article 17 or Article 19), either directly or indirectly through a limit on the effective handling of such goods, sufficient conditions for the transfer of the “right to dispose of the goods (that are subject to excise duty) as the owner” within the meaning of the VAT Directive, with the result that the taking over of the goods under an excise duty suspension arrangement by an authorised warehousekeeper or registered consignee should be treated as a supply of goods for VAT purposes? (6) In this context, when considering the determination of a supply which is linked to transport within a chain of supply of goods under an excise duty suspension arrangement with a single transport, is it necessary to regard a transport in the sense of the VAT Directive as commencing and closing in accordance with Article 20 of [Directive 2008/118]? (7) Does the principle of VAT neutrality or any other principle of EU law prevent application of the constitutional principle of in dubio mitius in national law, which obliges public authorities, where legal rules are ambiguous and objectively offer a number of possible interpretations, to choose the interpretation that benefits the person subject to the legal rule (here the taxable person for VAT)? Would the application of this principle be compatible with EU law at least if it were limited to situations where the relevant facts of the case preceded a binding interpretation of a disputed legal question by the Court, which has determined that another interpretation less favourable to the taxable entity is correct? If it is possible to apply the principle of in dubio mitius: (8) Was it possible, in terms of the limits set by EU law at the time when the taxable transactions took place in this case (November 2010 to May 2013), to consider the question whether the legal concept of supply of goods or transport of goods has (or does not have) the same content both for the purposes of the VAT Directive and for the purposes of [Directive 2008/118] objectively as legally uncertain and offering two interpretations?’
