(a) Does it constitute a material contractual amendment within the meaning of the case-law of the Court of Justice (judgment of 19 June 2008 in Case C-454/06 Pressetext) if a public undertaking hived off from another public undertaking concludes, in the context of transfer of part of a business within the meaning of Directive 2001/23/EC, (3) with the previous provider of occupational pension services to the hiving-off public undertaking, a new contract for the provision of occupational pensions which, for the purpose of safeguarding the rights of the transferred employees to old-age and invalidity benefits under an occupational pension scheme, is in that respect identical with the original contract and the hived-off public undertaking is controlled by the hiving-off public undertaking as sole proprietor? If Question 2(a) must be answered in the affirmative: (b) Is the use of a negotiated procedure without prior publication of a contract notice pursuant to Article 31(1)(b) of Directive 2004/18/EC with only one economic operator (namely, the previous service provider to the hiving-off public undertaking) permissible if the employees of the hiving-off public undertaking become, by way of transfer of a business, employees of the hived-off contracting authority and, in accordance with their contracts of employment transferred unaltered pursuant to Article 3(1) of Directive 2001/23/EC in conjunction with an established in-house practice, would be entitled as against their new employer, under national employment law, to demand that the occupational pension services be provided by the previous service provider with which the prospective entitlements accrued prior to transfer of the business? If Question (b) must be answered in the negative: (c) May a contracting authority which, prior to awarding a contract, did not publish a contact notice in the Official Journal of the European Union and did not follow an award procedure in accordance with Article 28 of Directive 2004/18/EC, exercise its right to specify performance — without infringing the procurement-law principles of competition, transparency and equal treatment — before following a proper award procedure, to the effect that, in specifying an implementation method for the occupational pension provision, it also specifies how the future service provider is to finance itself? May a contracting authority thus predetermine that only services of an unfunded pension scheme may be offered and that funded pension schemes are thus excluded, even though their obligations towards the insured employees may not differ pursuant to national employment law and by virtue of Article 3(1) of Directive 2001/23/EC? If Question 2(c) must be answered in the affirmative: (d) Does this apply before the expiry of the time-limit for the transposition of Directive 2014/24/EU even if that would have the effect that only one economic operator (namely, the previous service provider) was in a position to provide the service, or is a contracting authority which intends to use a negotiated procedure without publication of a contract notice with only one economic operator, pursuant to Article 31(1)(b) of Directive 2004/18/EC, required, when specifying performance, even before the expiry of the time-limit for the transposition of Directive 2014/24/EU, to ascertain that no reasonable alternative or substitute exists and that the absence of competition is not the result of an artificial narrowing down of the parameters of the procurement, as laid down in the second subparagraph of Article 32(2)(b) of Directive 2014/24/EU?
