‘Must Directive 2014/23/EU on the award of concession contracts, (1) as well as the general principles that follow from the Treaty, namely Articles 15, 16, 20 and 21 of the Charter of Fundamental Rights of the European Union, Article 3 of the Treaty on European Union and Articles 8, 49, 56, 12, 145 and 151 of the Treaty on the Functioning of the European Union, be interpreted as applying to concessions for the operation of the bingo game which were awarded under a selective tender procedure in 2000, expired and were subsequently repeatedly extended in their effects by legislative provisions which entered into force after the Directive had entered into force and the period for transposition thereof had expired?’

‘Does Directive 89/665/EC, (2) as amended by Directive 2014/23/EU, preclude an interpretation or application of domestic national provisions, or implementing practices based on those provisions, under which the legislature or the public administration may make participation in the procedure for the re-award of gaming concessions conditional on the concessionaire’s membership of the technical extension scheme, including in cases where it is not possible to renegotiate the operating conditions of the concession in order to bring them back into equilibrium as a result of unforeseen and unforeseeable events not attributable to the parties that have a significant impact on the normal conditions of operating risk, for as long as those conditions persist and for the time required to reinstate, where possible, the concessions’ original operating conditions?’

‘In any event, do Articles 49 and 56 TFEU and the principles of certainty and effectiveness of legal protection, as well as the principle of the protection of legitimate expectations, preclude an interpretation or application of domestic legislative provisions, or implementing practices based on those provisions, that would deprive the administration of the discretion to initiate, at the request of the interested parties, an administrative procedure to amend the conditions for the exercise of the concessions, with or without a new tender procedure, depending on whether or not the renegotiation of the contractual balance qualifies as a substantial change, in cases where unforeseen and unforeseeable events not attributable to the parties occur that have a significant impact on the normal conditions of operating risk, for as long as those conditions persist and for the time required to reinstate, where possible, the concessions’ original operating conditions?’
