Must Article 58 of Directive [2014/24], (1) the principal of proportionality and the principle of liability be interpreted as meaning that the contracting authority has the right to lay down the criteria relating to technical capacity, that is to say, to determine whether or not it is necessary to include in the procurement documents criteria relating to technical and professional capacity and the capacity to carry out the technical and professional activity arising from the provisions of special laws, in respect of activities of minor importance in the contract?

2.

Do the principles of transparency and proportionality preclude the automatic supplementation of the procurement documents with qualification criteria arising from special laws applicable to activities relating to the contract to be awarded which were not set out in the procurement documents and which the contracting authority decided not to impose on the economic operators?

3.

Do Article 63 of the directive and the principle of proportionality preclude the exclusion from the [tendering] procedure of a tenderer who has not named an operator as a subcontractor for the purpose of demonstrating compliance with certain criteria relating to technical and professional capacity and the capacity to carry out the technical and professional activity arising from the provisions of special laws not set out in the procurement documents in the case where the tenderer in question has chosen a different contractual form of involving specialists in the contract, that is to say [a] contract for the supply/provision of services, or has submitted [a] declaration of willingness on their part? Does the right to determine its organisation and contractual relations within the group lie with the economic operator and is it possible also to involve certain providers/suppliers in the contract in the case where the provider is not one of the entities on whose capacity the tenderer intends to rely in order to demonstrate compliance with the relevant criteria?
