Commission of the European Communities v Ireland.
Date: 2008-07-03
49. Member States must implement Directive 85/337 as amended in a manner which fully corresponds to its requirements, having regard to its fundamental objective which, as is clear from Article 2(1), is that, before development consent is given, projects likely to have significant effects on the environment by virtue, inter alia, of their nature, size or location should be made subject to a requirement for development consent and an assessment with regard to their effects (see, to that effect, Case C‑287/98 Linster  [2004] ECR I‑723, paragraph 52, and Case C‑486/04 Commission  v Italy  [2006] ECR I‑11025, paragraph 36).
57. While Community law cannot preclude the applicable national rules from allowing, in certain cases, the regularisation of operations or measures which are unlawful in the light of Community law, such a possibility should be subject to the conditions that it does not offer the persons concerned the opportunity to circumvent the Community rules or to dispense with applying them, and that it should remain the exception.
58. A system of regularisation, such as that in force in Ireland, may have the effect of encouraging developers to forgo ascertaining whether intended projects satisfy the criteria of Article 2(1) of Directive 85/337 as amended, and consequently, not to undertake the action required for identification of the effects of those projects on the environment and for their prior assessment. The first recital of the preamble to Directive 85/337 however states that 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.
59. Lastly, Ireland cannot usefully rely on Wells . Paragraphs 64 and 65 of that judgment point out that, under the principle of cooperation in good faith laid down in Article 10 EC, Member States are required to nullify the unlawful consequences of a breach of Community law. The competent authorities are therefore obliged to take the measures necessary to remedy failure to carry out an environmental impact assessment, for example the revocation or suspension of a consent already granted in order to carry out such an assessment, subject to the limits resulting from the procedural autonomy of the Member States.
61. It follows from the foregoing that, by giving to retention permission, which can be issued even where no exceptional circumstances are proved, the same effects as those attached to a planning permission preceding the carrying out of works and development, when, pursuant to Articles 2(1) and 4(1) and (2) of Directive 85/337 as amended, projects for which an environmental impact assessment is required must be identified and then – before the grant of development consent and, therefore, necessarily before they are carried out – must be subject to an application for development consent and to such an assessment, Ireland has failed to comply with the requirements of that directive.
98. It follows that Ireland was bound to subject the work on the projects to an impact assessment if they were likely to have significant effects on the environment, by virtue, inter alia, of their nature, size or location (see, to that effect, Case C‑72/95 Kraaijeveld and Others  [1996] ECR I‑5403, paragraph 50, and Case C‑2/07 Abraham and Others  [2008] ECR I‑0000, paragraph 37).
