Preliminary observations
15 It must be recalled, as a preliminary point, that the Court has jurisdiction under Article 267 TFEU to give preliminary rulings concerning inter alia the interpretation of the Treaties and of acts of the institutions of the European Union.
16 It is common ground that the dispute in the main proceedings concerns a provision of national law applicable within a purely internal context.
17 However, as may be seen from the order for reference, the Slovenian legislature decided, when transposing Directive 90/434 into the national legal system, to apply the tax treatment provided for by that directive also to purely internal situations, so that national and cross-border restructuring operations are subject to the same tax rules.
18 According to the Court’s case-law, where, in regulating purely internal situations, national legislation adopts the same solutions as those adopted in European Union law in order, in particular, to avoid discrimination against its own nationals or any distortion of competition, it is clearly in the European Union’s interest that, in order to forestall future differences of interpretation, provisions or concepts taken from European Union law should be interpreted uniformly, irrespective of the circumstances in which they are to apply (see Case C-28/95 Leur-Bloem [1997] ECR I-4161, paragraph 32; Case C-43/00 Andersen og Jensen [2002] ECR I-379, paragraph 18; and Case C-352/08 Modehuis A. Zwijnenburg [2010] ECR I-4303, paragraph 33).
19 It may be added that it is for the national court alone to assess the precise scope of that reference to European Union law, the jurisdiction of the Court being confined to considering provisions of European Union law only (see Leur-Bloem, paragraph 33, and Modehuis A. Zwijnenburg, paragraph 34).
20 It follows from the above considerations that the Court has jurisdiction to interpret the provisions of Directive 90/434, even though they do not directly govern the situation at issue in the main proceedings, and consequently to answer the question put by the referring court.
Substance
21 By its question the referring court essentially asks whether Article 11(1)(a) of Directive 90/434 must be interpreted as precluding national legislation, such as that at issue in the main proceedings, under which the grant of the tax advantages applicable to a division is subject to the condition that the application relating to that operation is submitted within a specified period, the starting-point of which is not known to the taxpayer, and on the expiry of which the taxpayer loses the right to those tax advantages without there having been an examination of whether he satisfies the conditions for their grant.
22 As noted by the applicant in the main proceedings, the Slovenian Government and the European Commission, who have submitted written observations to the Court, Directive 90/434 does not contain any provisions on the detailed procedures to be complied with by the Member States with a view to the grant of the tax advantages provided for by that directive.
23 In accordance with settled case-law of the Court, in the absence of relevant European Union rules, the detailed procedural rules designed to ensure the protection of the rights which individuals acquire under European Union law are a matter for the domestic legal order of each Member State, in accordance with the principle of the procedural autonomy of the Member States, provided that they are not less favourable than those governing similar domestic situations (principle of equivalence) and that they do not render impossible in practice or excessively difficult the exercise of rights conferred by the European Union legal order (principle of effectiveness) (see, inter alia, Joined Cases C-392/04 and C-422/04 i-21 Germany and Arcor [2006] ECR I-8559, paragraph 57, and Case C-262/09 Meilicke and Others [2011] ECR I-5669, paragraph 55).
24 As regards the principle of equivalence, it should be noted that in the present case there is nothing before the Court that is capable of raising any doubts as to the consistency with that principle of legislation such as that at issue in the main proceedings.
25 It must, on the other hand, be ascertained whether such legislation meets the requirements of the principle of effectiveness, which must be considered to be infringed where the exercise of rights conferred by the legal order of the European Union proves to be impossible or excessively difficult.
26 With respect to the rights conferred by Directive 90/434, it must be recalled that the common system of taxation laid down by that directive, which comprehends various tax advantages, applies without distinction to all mergers, divisions, transfers of assets and exchanges of shares, irrespective of the reasons, whether financial, economic or simply fiscal, for those operations (see Leur-Bloem, paragraph 36, and Modehuis A. Zwijnenburg, paragraph 41).
27 It is only by way of exception and in specific cases that the Member States may, pursuant to Article 11(1)(a) of Directive 90/434, refuse to apply or withdraw the benefit of all or any part of the provisions of that directive (Case C-321/05 Kofoed [2007] ECR I-5795, paragraph 37, and Modehuis A. Zwijnenburg, paragraph 45), namely when the restructuring envisaged has as its principal objective or as one of its principal objectives tax evasion or tax avoidance.
28 In the present case, according to the documents before the Court, the taxpayer must, in accordance with Article 47 of the ZDDPO-1 in conjunction with Article 363(2) of the ZDavP-1, submit his application to be granted the tax advantages provided for by Directive 90/434 at least 30 days before the proposed restructuring operation, failing which he forfeits the rights conferred by that directive.
29 It must therefore be ascertained whether that period of 30 days meets the requirements of the principle of effectiveness with respect both to its length and to its starting-point.
30 As regards the length of the period, the Court has previously held, in the context of analysing the principle of effective judicial protection of the rights conferred on individuals by European Union law, that it is compatible with that law to lay down reasonable time-limits for bringing proceedings in the interests of legal certainty which protects both the taxpayer and the administration concerned. Such time-limits do not make it impossible in practice or excessively difficult to exercise the rights conferred by the European Union legal order (Case C-261/95 Palmisani [1997] ECR I-4025, paragraph 28, and Case C-228/96 Aprile [1998] ECR I-7141, paragraph 19). In this connection, the Court has also held that a period of 60 days for bringing proceedings is not objectionable in itself (Case C-312/93 Peterbroeck [1995] ECR I-4599, paragraph 16, and Case C-40/08 Asturcom Telecomunicaciones [2009] ECR I-9579, paragraph 43).
31 Moreover, the Court has held that that case-law also applies to the assessment of rules for the restitution of national taxes unduly levied (Meilicke and Others, paragraphs 55 to 58). The same must therefore apply to the assessment of compliance with the principle of effectiveness as regards the setting of a time-limit in connection with the submission of an application to be granted tax advantages.
32 Consequently, it does not appear that national legislation which grants the tax advantages provided for by Directive 90/434 only on condition that the relevant application is made at least 30 days before the proposed restructuring operation is liable to make it impossible in practice or excessively difficult to exercise the rights derived by the taxpayer from European Union law.
33 While an exclusionary time-limit such as that at issue in the main proceedings is not therefore contrary in itself to the principle of effectiveness, it cannot however be ruled out that, in the context of the particular circumstances of the case before the referring court, the application of that time-limit might entail a breach of that principle.
34 As regards the starting-point of the 30-day period laid down in Article 363(2) of the ZDavP-1, it appears from the order for reference that the period is calculated backwards from the date on which the restructuring operation is effected, the date on which the operation is regarded as taking place being the date of registration of that operation in the register of commercial companies by the competent court.
35 Consequently, in such a situation, the time during which the 30-day period runs does not depend on the taxpayer, since he is not in a position to know precisely either when it starts or when it ends, namely on the date of entry in the register of commercial companies of the proposed restructuring operation.
36 It should be recalled that the objectives pursued by Directive 90/434 must be achieved in national law in compliance with the requirements of legal certainty. To that end, the Member States have an obligation to establish a system of time-limits that is sufficiently precise, clear and foreseeable to enable individuals to ascertain their rights and obligations (see, by analogy, Case C-406/08 Uniplex (UK) [2010] ECR I-817, paragraph 39 and the case-law cited). It is for the national court to establish whether those requirements are complied with.
37 In the light of the above considerations, the answer to the question is that Article 11(1)(a) of Directive 90/434 must be interpreted as not precluding national legislation, such as that at issue in the main proceedings, under which the grant of the tax advantages applicable to a division in accordance with that directive is subject to the condition that the application relating to that operation is submitted within a specified period. However, it is for the national court to ascertain whether the details of the implementation of that period, and more particularly the determination of its starting-point of the period, are sufficiently precise, clear and foreseeable to enable taxpayers to ascertain their rights and to ensure that they are in a position to enjoy the tax advantages provided for by that directive.
