The disputes in the main proceedings and the question referred for a preliminary ruling

Case C‐196/16

| 8 | On 19 October 2011, VBIO1 sought consent from the Regione Marche (Marche Region, Italy) to build and operate a plant for the generation of electrical energy from biogas obtained from the anaerobic fermentation of biomass within the territory of the municipality of Corridonia. |
| --- | --- |

8

On 19 October 2011, VBIO1 sought consent from the Regione Marche (Marche Region, Italy) to build and operate a plant for the generation of electrical energy from biogas obtained from the anaerobic fermentation of biomass within the territory of the municipality of Corridonia.

| 9 | Pursuant to the legge Regione Marche No 7/2004 (Law No 7/2004 of the Marche Region), VBIO1 had also submitted that project to the Provincia di Macerata (Province of Macerata, Italy) on 4 October 2011 for a preliminary examination as to the need for an environmental assessment. |
| --- | --- |

9

Pursuant to the legge Regione Marche No 7/2004 (Law No 7/2004 of the Marche Region), VBIO1 had also submitted that project to the Provincia di Macerata (Province of Macerata, Italy) on 4 October 2011 for a preliminary examination as to the need for an environmental assessment.

| 10 | That procedure was, however, closed on 26 January 2012, after Law No 7/2004 of the Marche Region had been amended by the legge Regione Marche No 20/2011 (Law No 20/2011 of the Marche Region), which entered into force on 9 November 2011 and by virtue of which projects the heating potential of which did not reach a certain threshold were no longer required to undergo an assessment of their impact on the environment. |

That procedure was, however, closed on 26 January 2012, after Law No 7/2004 of the Marche Region had been amended by the legge Regione Marche No 20/2011 (Law No 20/2011 of the Marche Region), which entered into force on 9 November 2011 and by virtue of which projects the heating potential of which did not reach a certain threshold were no longer required to undergo an assessment of their impact on the environment.

| 11 | Consequently, the Marche Region consented, by decision of 5 June 2012, to the construction and operation of that plant in the municipality of Corridonia, which challenged that decision by bringing an action before the Tribunale amministrativo regionale per le Marche (Administrative Court for the Marche Region, Italy). |

Consequently, the Marche Region consented, by decision of 5 June 2012, to the construction and operation of that plant in the municipality of Corridonia, which challenged that decision by bringing an action before the Tribunale amministrativo regionale per le Marche (Administrative Court for the Marche Region, Italy).

| 12 | By judgment of 10 October 2013, that court annulled the decision on the ground that Law No 20/2011 of the Marche Region was inapplicable and that, in any event, the relevant provisions of that law were incompatible with Directive 2011/92. That judgment was upheld by the Consiglio di Stato (Council of State, Italy). |

On 15 November 2013, the Province of Macerata decided that such an assessment was necessary and, subsequent to that assessment, found, on 7 July 2014, that that plant complied with the environmental requirements.

| 15 | The municipality of Corridonia lodged an application for annulment of those decisions before the Tribunale amministrativo regionale per le Marche (Administrative Court for the Marche Region), maintaining that the assessment carried out did not comply with Article 191 TFEU or with Article 2(1) to (3) of Directive 85/337, replaced by Directive 2011/92, given that it had been carried out after the plant in question had been built. |

The municipality of Loro Piceno and Mr Bartolini and Others applied to the Tribunale amministrativo regionale per le Marche (Administrative Court for the Marche Region) for annulment of that decision.

| 27 | In Cases C‐196/16 and C‐197/16, the Tribunale amministrativo regionale per le Marche (Administrative Court for the Marche Region) decided to stay proceedings and to refer the following question to the Court for a preliminary ruling:
  ‘On a constructive interpretation of Article 191 TFEU and Article 2 of Directive [2011/92], is it compatible with EU law to proceed with the verification of whether an environmental impact assessment needs to be undertaken (and possibly thereafter to carry out an environmental impact assessment) after the construction of the plant where the consent has been annulled by the national court due to a failure to verify whether the environmental impact assessment was needed, because such a verification had been excluded on the basis of a national law which was contrary to EU law?’ |
| --- | --- |

27

In Cases C‐196/16 and C‐197/16, the Tribunale amministrativo regionale per le Marche (Administrative Court for the Marche Region) decided to stay proceedings and to refer the following question to the Court for a preliminary ruling:

‘On a constructive interpretation of Article 191 TFEU and Article 2 of Directive [2011/92], is it compatible with EU law to proceed with the verification of whether an environmental impact assessment needs to be undertaken (and possibly thereafter to carry out an environmental impact assessment) after the construction of the plant where the consent has been annulled by the national court due to a failure to verify whether the environmental impact assessment was needed, because such a verification had been excluded on the basis of a national law which was contrary to EU law?’

Consideration of the question referred

| 28 | In these two cases, the referring court asks, in essence, whether Article 191 TFEU and Article 2 of Directive 2011/92, in circumstances such as those in the main proceedings, mean that the failure to carry out an environmental impact assessment of a plant project required pursuant to Directive 85/337 cannot be regularised, following the annulment of consent granted in respect of that plant, by such an assessment being carried out after that plant has been built and has entered into operation. |

In these two cases, the referring court asks, in essence, whether Article 191 TFEU and Article 2 of Directive 2011/92, in circumstances such as those in the main proceedings, mean that the failure to carry out an environmental impact assessment of a plant project required pursuant to Directive 85/337 cannot be regularised, following the annulment of consent granted in respect of that plant, by such an assessment being carried out after that plant has been built and has entered into operation.

| 29 | As a preliminary point, it is necessary to note that Article 191 TFEU, paragraph 2 of which fixes general objectives in environmental matters (see, to that effect, judgment of 4 March 2015, Fipa Group and Others, C‐534/13, EU:C:2015:140, paragraph 39 and the case-law cited), is irrelevant for the purposes of answering the questions posed. |

As a preliminary point, it is necessary to note that Article 191 TFEU, paragraph 2 of which fixes general objectives in environmental matters (see, to that effect, judgment of 4 March 2015, Fipa Group and Others, C‐534/13, EU:C:2015:140, paragraph 39 and the case-law cited), is irrelevant for the purposes of answering the questions posed.

| 30 | Moreover, the question posed by the referring court rests on the premiss that the two plants at issue in the main proceedings ought to have been the subject of a prior assessment of their impact on the environment, by virtue of Article 2(1) of Directive 85/337, which is a matter for that court to assess. |

| 31 | Finally, as regards the question of whether, in order to answer the question posed, it is appropriate to take into account Directive 85/337, in force when VBIO1 and VBIO2 submitted the first applications for consent, or Directive 2011/92, in force when they submitted the second applications, following the annulment of the first consents granted to them, it is sufficient to note that the provisions of those two directives which are or could be relevant in the present case, and Article 2(1) of those directives in particular, are, in any event, essentially identical. |

Finally, as regards the question of whether, in order to answer the question posed, it is appropriate to take into account Directive 85/337, in force when VBIO1 and VBIO2 submitted the first applications for consent, or Directive 2011/92, in force when they submitted the second applications, following the annulment of the first consents granted to them, it is sufficient to note that the provisions of those two directives which are or could be relevant in the present case, and Article 2(1) of those directives in particular, are, in any event, essentially identical.

| 32 | As to whether it is possible to regularise a posteriori the failure to carry out an environmental impact assessment of a project as required under Directive 85/337, in circumstances such as those at issue in the main proceedings, it should be remembered that Article 2(1) of that directive provides that projects that may have a significant impact on the environment, within the meaning of Article 4 of that directive, read in conjunction with Annex I or II to that directive, must be subject to that assessment before consent is granted (judgment of 7 January 2004, Wells, C‐201/02, EU:C:2004:12, paragraph 42). |

| 33 | As the Court has also emphasised, the prior nature of such an assessment is justified by the fact it is necessary for the competent authority to take effects on the environment into account at the earliest possible stage in all the technical planning and decision-making processes, the objective being to prevent the creation of pollution or nuisances at source rather than subsequently trying to counteract their effects (judgment of 3 July 2008, Commission v Ireland, C‐215/06, EU:C:2008:380, paragraph 58). |

However, neither Directive 85/337 nor Directive 2011/92 contains provisions relating to the consequences of a breach of that obligation to carry out a prior assessment.

| 35 | Under the principle of cooperation in good faith laid down in Article 4 TEU, Member States are nevertheless required to nullify the unlawful consequences of that breach of EU law. The competent national authorities are therefore under an obligation to take all measures necessary, within the sphere of their competence, to remedy the failure to carry out an environmental impact assessment, for example by revoking or suspending consent already granted in order to carry out such an assessment (see, to that effect, judgments of 7 January 2004, Wells, C‐201/02, EU:C:2004:12, paragraphs 64 and 65; of 3 July 2008, Commission v Ireland, C‐215/06, EU:C:2008:380, paragraph 59; and of 28 February 2012, Inter-Environnement Wallonie and Terre wallonne, C‐41/11, EU:C:2012:103, paragraphs 42, 43 and 46). |

| 36 | The Member State concerned is likewise required to make good any harm caused by the failure to carry out an environmental impact assessment (judgment of 7 January 2004, Wells, C‐201/02, EU:C:2004:12, paragraph 66). |

| 37 | The Court has, however, held that EU law does not preclude national rules which, in certain cases, permit the regularisation of operations or measures which are unlawful in the light of EU law (judgments of 3 July 2008, Commission v Ireland, C‐215/06, EU:C:2008:380, paragraph 57; of 15 January 2013, Križan and Others, C‐416/10, EU:C:2013:8, paragraph 87; and of 17 November 2016, Stadt Wiener Neustadt, C‐348/15, EU:C:2016:882, paragraph 36). |

The Court has, however, held that EU law does not preclude national rules which, in certain cases, permit the regularisation of operations or measures which are unlawful in the light of EU law (judgments of 3 July 2008, Commission v Ireland, C‐215/06, EU:C:2008:380, paragraph 57; of 15 January 2013, Križan and Others, C‐416/10, EU:C:2013:8, paragraph 87; and of 17 November 2016, Stadt Wiener Neustadt, C‐348/15, EU:C:2016:882, paragraph 36).

| 38 | The Court has made it clear that such a possible regularisation would have to be subject to the condition that it does not offer the persons concerned the opportunity to circumvent the rules of EU law or to dispense with their application, and that it should remain the exception (judgments of 3 July 2008, Commission v Ireland, C‐215/06, EU:C:2008:380, paragraph 57; of 15 January 2013, Križan and Others, C‐416/10, EU:C:2013:8, paragraph 87; and of 17 November 2016, Stadt WienerNeustadt, C‐348/15, EU:C:2016:882, paragraph 36). |

| 39 | Consequently, the Court has held that legislation which attaches the same effects to regularisation permission, which can be issued even where no exceptional circumstances are proved, as those attached to prior planning consent fails to have regard for the requirements of Directive 85/337 (see, to that effect, judgments of 3 July 2008, Commission v Ireland, C‐215/06, EU:C:2008:380, paragraph 61, and of 17 November 2016, Stadt Wiener Neustadt, C‐348/15, EU:C:2016:882, paragraph 37). |

| 40 | The same is also true of a legislative measure which could allow, without even requiring a later assessment and even where there are no specific exceptional circumstances, a project which ought to have been subject to an environmental impact assessment, by virtue of Article 2(1) of Directive 85/337, to be deemed to have been subject to such an assessment, even if such a measure were applicable only to projects in respect of which consent was no longer subject to a possibility of being directly challenged before the courts because of the expiry of the time limit for bringing proceedings laid down in national legislation (see, to that effect, judgment of 17 November 2016, Stadt Wiener Neustadt, C‐348/15, EU:C:2016:882, paragraphs 38 and 43). |

| 41 | Furthermore, an assessment carried out after a plant has been constructed and has entered into operation cannot be confined to its future impact on the environment, but must also take into account its environmental impact from the time of its completion. |

Furthermore, an assessment carried out after a plant has been constructed and has entered into operation cannot be confined to its future impact on the environment, but must also take into account its environmental impact from the time of its completion.

| 42 | It is for the referring court to assess whether the legislation at issue in the main proceedings satisfies those requirements. It is, however, appropriate to mention to the referring court that the facts that the undertakings concerned took the necessary steps to arrange for, if need be, an assessment of the environmental impact of their projects to be carried out, that the refusal of the competent authorities to accede to those requests was based on national rules, the incompatibility of which with EU law was only subsequently established by a ruling of the Corte costituzionale (Constitutional Court), and that the activities of the plants concerned were suspended appear rather to indicate that the regularisations carried out were not permitted under national law in conditions similar to those in the case leading to the judgment of 3 July 2008, Commission v Ireland (C‐215/06, EU:C:2008:380, paragraph 61), and did not attempt to circumvent rules of EU law. |

| 43 | In the light of all of the foregoing considerations, the answer to the question posed is that, in the event of failure to carry out an environmental impact assessment required under Directive 85/337, EU law, on the one hand, requires Member States to nullify the unlawful consequences of that failure and, on the other hand, does not preclude regularisation through the conducting of an impact assessment, after the plant concerned has been constructed and has entered into operation, on condition that:
