75Under the principle of sincere cooperation provided for in Article 4(3) TEU, Member States are nevertheless required to eliminate the unlawful consequences of that breach of EU law. That obligation applies to every organ of the Member State concerned and, in particular, to the national authorities which have the 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, paragraph 64, and of 26 July 2017, Comune di Corridonia and Others, C‑196/16 and C‑197/16, EU:C:2017:589, paragraph 35).
