32As 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).
