This request for a preliminary ruling concerns the interpretation of Article 14(1)(a) and of the third subparagraph of Article 21(5) of Council Directive 2003/96/EC of 27 October 2003 restructuring the Community framework for the taxation of energy products and electricity (OJ 2003 L 283, p. 51).

2

The request was made in the context of a dispute between UPM France SAS (‘UPM’) and the Premier ministre and the ministre de l’Action et des Comptes publics (the Prime Minister and the Minister for Action and Public Accounts; ‘the Ministers’) concerning the taxation of supplies of natural gas for the cogeneration of heat and electricity.

3

Recitals 2 to 5, 24 and 25 of Directive 2003/96 state:

…

4

Article 1 of Directive 2003/96 provides that the Member States are to impose taxation on energy products and electricity in accordance with that directive.

5

Under Article 14(1)(a) of that directive:

‘In addition to the general provisions set out in [Council] Directive 92/12/EEC [of 25 February 1992 on the general arrangements for products subject to excise duty and on the holding, movement and monitoring of such products (OJ 1992 L 76, p. 1)] on exempt uses of taxable products, and without prejudice to other Community provisions, Member States shall exempt the following from taxation under conditions which they shall lay down for the purpose of ensuring the correct and straightforward application of such exemptions and of preventing any evasion, avoidance or abuse:

6

Article 15(1)(c) of that directive provides:

‘Without prejudice to other Community provisions, Member States may apply under fiscal control total or partial exemptions or reductions in the level of taxation to:

…

7

Article 18 of Directive 2003/96 establishes specific transitional regimes for certain Member States. As regards the French Republic, Article 18(10) of that directive provides:

‘The French Republic may apply total or partial exemptions or reductions for energy products and electricity used by the State, regional and local government authorities or other bodies governed by public law, in respect of the activities or transactions in which they engage as public authorities until 1 January 2009.

The French Republic may apply a transitional period until 1 January 2009 to adapt its current electricity taxation system to the provisions set out in this directive. During this period, the global average level of the current local electricity taxation is to be taken into account to assess whether the minimum rates set out in this directive are respected.’

8

Under Article 21 of that directive:

‘1.   In addition to the general provisions defining the chargeable event and the provisions for payment set out in [Directive 92/12], the amount of taxation on energy products shall also become due on the occurrence of one of the chargeable events mentioned in Article 2(3).

…

5.   ...

An entity producing electricity for its own use is regarded as a distributor. Notwithstanding Article 14(1)(a), Member States may exempt small producers of electricity provided that they tax the energy products used for the production of that electricity.

…’

9

Article 28 of Directive 2003/96 provides that Member States are to apply its provisions from 1 January 2004, with the exception of the provisions of Article 16 and Article 18(1) of that directive, which Member States may apply from 1 January 2003.

10

Article 266d(1) of the Code des douanes (Customs Code), in the version applicable from 1 January 2004 to 31 December 2006, provided:

‘Natural gas … shall be subject to a domestic tax on consumption on delivery to the end user.’

11

Article 266d(3) of the Customs Code, in its version applicable from 1 January 2006 to 31 December 2006, provided:

‘…

Supplies of gas shall also be exempt when they are intended for use:

…

12

Article 266dA of the Customs Code, in the version applicable from 1 January 2006, stated:

‘Supplies of natural gas and mineral oils intended for use in cogeneration units for the combined generation of heat and electricity or heat and mechanical power shall be exempt from the domestic taxes on consumption imposed by Articles 265 and 266d for a period of five years from the entry into service of the units. …

That exemption shall apply to units put into service no later than 31 December 2007. …

…’

13

UPM operates a heat and power cogeneration facility for its paper manufacturing business, using natural gas as fuel.

14

The natural gas delivered to UPM between 1 January 2004 and 1 April 2008 was subject to the domestic natural gas consumption tax (‘the TICGN’) provided for in Article 266d of the Customs Code, through its supplier who paid the amount due.

15

Being of the view that the fraction of those supplies consumed to produce electricity should have been exempted from that tax by virtue of Article 14(1)(a) of Directive 2003/96, UPM brought an action before the tribunal administratif de Cergy-Pontoise (Administrative Court, Cergy-Pontoise, France) seeking a refund of the tax thus incurred and for compensation for the damage it alleges it has suffered as a result of the French Republic’s delay in transposing that directive.

16

By judgment of 17 July 2013, the tribunal administratif de Cergy-Pontoise (Administrative Court, Cergy-Pontoise), after finding that there was, in part, no need to adjudicate concerning the amounts reimbursed for the period from 1 January 2007 to 31 March 2008, rejected UPM’s claims as to the remainder. By judgment of 15 March 2016, the cour administrative d’appel de Versailles (Administrative Court of Appeal, Versailles, France), dismissed UPM’s appeal on the grounds that the natural gas used by UPM fell exclusively under Article 15 of the directive, not under Article 14 thereof, and that the tax regime for that natural gas could not be dissociated according to whether it was intended for heat production or electricity production.

17

On 17 May 2016, UPM lodged an appeal against that judgment before the referring court, the Conseil d’État (Council of State, France).

18

That court notes that the ground raised by UPM is based on the judgment of 7 March 2018, Cristal Union (C‑31/17, EU:C:2018:168), in which the Court held that Article 14(1)(a) of Directive 2003/96 must be interpreted as meaning that the mandatory exemption provided for in that provision applies to energy products used for the production of electricity when those products are used for the combined production of electricity and heat within the meaning of Article 15(1)(c) of that directive.

19

However, the national court states that the Minister for Action and Public Accounts, the respondent in the main proceedings, maintains that, even if Article 15 of Directive 2003/96 is not the only provision applicable to UPM’s situation, the taxation to which it has been subject is consistent with the objectives of that directive, since Article 14(1)(a) of that directive must be read in the light of the third subparagraph of Article 21(5) thereof, from which it follows that the exemption in respect of natural gas used to produce electricity is subject to taxation of the electricity produced, which is not the case here.

20

The national court states that, pursuant to the second subparagraph of Article 18(10) of Directive 2003/96, the French Republic enjoyed, until 1 January 2009, a transitional period in which to adapt its electricity taxation system before introducing harmonised excise duty. However, it was only from the entry into force of loi No 2010-1488 du 7 décembre 2010 portant nouvelle organisation du marché de l’électricité (Law No 2010-1488 of 7 December 2010 on the new organisation of the electricity market; JORF, 8 December 2010, p. 21467) that an internal tax on final electricity consumption was introduced.

21

Thus, the French Republic did not provide for any national electricity taxation during the period from 1 January 2004 to 31 December 2006, which is the period at issue in the main proceedings. Only the contribution to the public electricity service and local taxes, based at that time on the amount net of tax invoiced in respect of electricity, were levied on electricity consumption. However, entities producing electricity for their own use were exempt from local electricity taxation.

22

Consequently, according to the national court, it must be determined whether the exemption which Member States are authorised to grant to small electricity producers, pursuant to the third subparagraph of Article 21(5) of Directive 2003/96, can result, as the Minister for Action and Public Accounts claims, in a situation, such as that existing for the period prior to 1 January 2011, during which the French Republic had not yet introduced internal taxation on final electricity consumption or, consequently, exemption from this tax in favour of small producers. Where appropriate, it should also be determined how the provisions of Article 14(1)(a) of Directive 2003/96 and the third subparagraph of Article 21(5) of that directive are to be combined, in particular in order to determine whether they involve minimum taxation resulting from the taxation of electricity produced with exemption of the natural gas used or an exemption from tax on electricity production, the Member State then being required to tax the natural gas used.

23

In those circumstances, the Conseil d’État (Council of State) decided to stay the proceedings and to refer the following questions to the Court for a preliminary ruling:

24

The French Government disputes the admissibility of the request for a preliminary ruling, since the answer to the questions raised is not necessary for the effective resolution of the main proceedings.

25

According to that government, during the transitional period which the French Republic enjoyed in order to adapt its electricity taxation system pursuant to Article 18(10) of Directive 2003/96, that Member State was able to maintain its national electricity taxation system, since it complied with the minimum tax rates set by that directive.

26

In that regard, it should be recalled that it is solely for the national court before which the dispute has been brought, and which must assume responsibility for the subsequent judicial decision, to determine in the light of the particular circumstances of the case both the need for a preliminary ruling in order to enable it to deliver judgment and the relevance of the questions which it submits to the Court. Consequently, where the questions submitted concern the interpretation of a rule of EU law, the Court is in principle bound to give a ruling (judgment of 10 December 2018, Wightman and Others, C‑621/18, EU:C:2018:999, paragraph 26 and the case-law cited).

27

It follows that questions relating to EU law enjoy a presumption of relevance. The Court may refuse to rule on a question referred for a preliminary ruling by a national court only where it is quite obvious that the interpretation of EU law that is sought bears no relation to the actual facts of the main action or its purpose, where the problem is hypothetical, or where the Court does not have before it the factual or legal material necessary to give a useful answer to the questions submitted to it (judgment of 10 December 2018, Wightman and Others, C‑621/18, EU:C:2018:999, paragraph 27 and the case-law cited).

28

In the present case, it must be recalled that an appeal was brought before the national court against a decision rejecting UPM’s claim for reimbursement of the TICGN provided for in Article 266d of the Customs Code, since the company considered that the fraction of natural gas used to produce electricity should have been exempt from that tax, in accordance with Article 14(1)(a) of Directive 2003/96.

29

In those circumstances, it does not appear that the questions referred for a preliminary ruling, where they concern the interpretation of provisions of EU law in the context of a dispute pending before the referring court, are manifestly irrelevant.

30

It is irrelevant in that regard that the French Republic has been granted, pursuant to Article 18(10) of Directive 2003/96, a transitional period to adapt its electricity taxation system to the provisions of that directive, those considerations relating to the substance of the answers to be given to the questions asked and not to their admissibility.

31

Consequently, those questions must be deemed admissible.

32

By its first question, the national court asks, in essence, whether the second sentence of the third subparagraph of Article 21(5) of Directive 2003/96 must be interpreted as meaning that the exemption provided for in that provision for small electricity producers, provided that, by way of derogation from Article 14(1)(a) of that directive, the energy products used to produce that electricity are taxed, could be applied by the French Republic during the transitional period granted to it, in accordance with the second subparagraph of Article 18(10) of that directive, until 1 January 2009 and during which that Member State did not introduce the electricity taxation system provided for in that directive.

33

The file submitted to the Court shows that, between 1 January 2004 and 1 April 2008, UPM was subject to the TICGN in respect of the natural gas it used to generate electricity. It is also common ground that, since the electricity thus produced was used for its own purposes, it was not subject to local electricity taxes.

34

The French Government claims that, where the electricity produced has in fact been exempted, the energy products intended for the production of that electricity must be taxed. Directive 2003/96 in itself implies a minimum taxation resulting either from the taxation of electricity produced with exemption of the energy products used to produce that electricity or from the minimum taxation of the energy products used to produce electricity when the latter is exempt.

35

It is in that context that the referring court seeks to ascertain whether the taxation of the natural gas used by the appellant in the main proceedings to produce electricity, while the French Republic had not introduced either the internal tax on final consumption of electricity, referred to in paragraph 20 of this judgment, or, consequently, an exemption from that tax for small producers, is in accordance with the second sentence of the third subparagraph of Article 21(5) of Directive 2003/96.

36

It must be borne in mind that Directive 2003/96 provides for the introduction of harmonised taxation on energy products and electricity.

37

In that regard, it is apparent from the objectives pursued by that directive that it provides for a harmonised taxation regime for energy products and electricity designed, inter alia, as is apparent from recitals 2 to 5 and 24 thereof, to promote the smooth functioning of the internal market in the energy sector by avoiding, inter alia, distortions of competition (see, to that effect, judgments of 7 March 2018, Cristal Union, C‑31/17, EU:C:2018:168, paragraph 29, and of 27 June 2018, Turbogás, C‑90/17, EU:C:2018:498, paragraph 34).

38

To that end, in particular with regard to electricity, the EU legislature has made the choice, as can be seen, in particular, from page 5 of the explanatory memorandum to the Proposal for a Council Directive restructuring the Community framework for the taxation of energy products (OJ 1997 C 139, p. 14), to impose on Member States, in accordance with Article 1 of Directive 2003/96, taxation of distributed electricity, with the energy products used for its production being, at the same time, exempted from taxation in order to avoid double taxation of electricity (judgments of 7 March 2018, Cristal Union, C‑31/17, EU:C:2018:168, paragraph 30, and of 27 June 2018, Turbogás, C‑90/17, EU:C:2018:498, paragraph 35).

39

Thus, the first sentence of Article 14(1)(a) of Directive 2003/96 provides that Member States are required to exempt energy products and electricity used, in particular, to produce electricity. In accordance with the first subparagraph of Article 21(5) of that directive, the electricity and natural gas used to produce electricity are then to be subject to taxation at the time of their supply by the distributor or redistributor.

40

However, the second sentence of the third subparagraph of Article 21(5) of that directive provides for an exception to these provisions in favour of small producers, since Member States may exempt electricity produced by them, provided that they tax the energy products used to produce that electricity.

41

Thus, it is by way of exception to that principle of downstream taxation of electricity that the second sentence of the third subparagraph of Article 21(5) thereof gives Member States the option of exempting electricity produced by small producers and consumed for their own use, provided that they tax the energy products used to produce that electricity (judgment of 27 June 2018, Turbogás, C‑90/17, EU:C:2018:498, paragraph 36).

42

The Court has previously ruled, in paragraph 37 of the judgment of 27 June 2018, Turbogás (C‑90/17, EU:C:2018:498), that the provisions of the second sentence of the third subparagraph of Article 21(5), relating to small producers, concern only the arrangements under which electricity is subject to the harmonised taxation regime introduced by Directive 2003/96 in order to avoid, in particular, administrative costs relating to taxation in that particular situation.

43

However, the taxation of the natural gas at issue in the main proceedings cannot be regarded as resulting from the derogating taxation scheme provided for in the second sentence of the third subparagraph of Article 21(5) of that directive in respect of small producers. The French Republic had not introduced the electricity taxation scheme from which this provision allows for derogation.

44

In accordance with the second subparagraph of Article 18(10) of Directive 2003/96, the French Republic was granted a transitional period until 1 January 2009 to adapt its electricity taxation system to the provisions of that directive.

45

Thus, until that date, compliance with the minimum levels of taxation laid down in Directive 2003/96 constituted, among the electricity taxation rules provided for in EU law, the only obligation resting on the French Republic (see, to that effect, judgment of 25 July 2018, Messer France, C‑103/17, EU:C:2018:587, paragraph 23).

46

The French Republic was therefore free to maintain its electricity taxation system in place before the entry into force of Directive 2003/96.

47

However, the Court has previously found, in paragraph 31 of the judgment of 25 July 2018, Messer France (C‑103/17, EU:C:2018:587), that, for the period in question in the main proceedings, the French Republic had not amended its electricity taxation system to create such an excise duty. It is apparent from the file submitted to the Court that that duty was introduced by Law No 2010-1488 of 7 December 2010 on the new organisation of the electricity market, referred to in paragraph 20 of this judgment, which created the internal tax on final electricity consumption.

48

As the Court has pointed out in paragraph 42 of this judgment, the second sentence of the third subparagraph of Article 21(5) of Directive 2003/96 was merely a means of applying the harmonised taxation system (see, to that effect, judgment of 27 June 2018, Turbogás, C‑90/17, EU:C:2018:498, paragraph 37). Consequently, as regards the main proceedings, the French Republic cannot rely on a method of applying a scheme which had not been put in place at the time of the events relating to those proceedings.

49

With regard to the argument of the French Government concerning the transitional period provided for in the second subparagraph of Article 18(10) of Directive 2003/96, it must be borne in mind that that transitional period must be interpreted strictly (see, by analogy, judgments of 7 December 2006, Eurodental, C‑240/05, EU:C:2006:763, paragraph 54, and of 27 February 2019, Greece v Commission, C‑670/17 P, EU:C:2019:145, paragraph 52). However, it appears from the wording of that provision that the transitional period provided for therein concerns the fact that the French Republic may adapt only its electricity taxation system and not that of taxation of energy products used to produce electricity.

50

Such a reading of the second subparagraph of Article 18(10) of Directive 2003/96 is confirmed by the fact that the EU legislature has explicitly referred to such products under the transitional regime provided for in the first subparagraph of Article 18(10), which specifies that the French Republic may apply total or partial exemptions or reductions in respect of those energy products and electricity used by the State, regional and local authorities or other bodies governed by public law.

51

Accordingly, during the transitional period referred to in the second subparagraph of Article 18(10) of Directive 2003/96, the provisions on the exemption of energy products used to produce electricity laid down by that directive were fully applicable to the French Republic.

52

However, as the Court has previously held, when the EU legislature intended to allow Member States to derogate from the regime of mandatory exemption introduced by Directive 2003/96, it did so explicitly in, respectively, the second sentence of Article 14(1)(a) of Directive 2003/96, which states that Member States may tax energy products used to produce electricity for reasons relating to the protection of the environment, and in the second sentence of the third subparagraph of Article 21(5) of that directive, under which Member States which exempt electricity generated by small producers of electricity must tax the energy products used for the generation of that electricity (judgment of 7 March 2018, Cristal Union, C‑31/17, EU:C:2018:168, paragraph 27).

53

It is thus apparent from the general scheme of Directive 2003/96 that, apart from those two specific cases, the mandatory exemption of energy products used to generate electricity referred to in the first sentence of Article 14(1)(a) of that directive is unconditionally binding on the Member States (judgment of 7 March 2018, Cristal Union, C‑31/17, EU:C:2018:168, paragraph 28).

54

In the light of all the foregoing considerations, the answer to the first question is that the second sentence of the third subparagraph of Article 21(5) of Directive 2003/96 must be interpreted as meaning that the exemption provided for in that provision for small electricity producers, provided that, by way of derogation from Article 14(1)(a) of that directive, the energy products used to produce that electricity are taxed, could not be applied by the French Republic during the transitional period granted to it, in accordance with the second subparagraph of Article 18(10) of that directive, until 1 January 2009 and during which that Member State did not introduce the electricity taxation system provided for in that directive.

55

In the light of the answer given to the first question, there is no need to answer the second question.

56

Since these proceedings are, for the parties to the main proceedings, a step in the action pending before the national court, the decision on costs is a matter for that court. Costs incurred in submitting observations to the Court, other than the costs of those parties, are not recoverable.

On those grounds, the Court (Fifth Chamber) hereby rules:

The second sentence of the third subparagraph of Article 21(5) of Council Directive 2003/96/EC of 27 October 2003 restructuring the Community framework for the taxation of energy products and electricity must be interpreted as meaning that the exemption provided for in that provision for small electricity producers, provided that, by way of derogation from Article 14(1)(a) of that directive, the energy products used to produce that electricity are taxed, could not be applied by the French Republic during the transitional period granted to it, in accordance with the second subparagraph of Article 18(10) of that directive, until 1 January 2009 and during which that Member State did not introduce the electricity taxation system provided for in that directive.
