Judgment_paragraph 28 · People Over Wind and Peter Sweetman v Coillte Teoranta (C-323/17)

28The 10th recital of the Habitats Directive states that an appropriate assessment must be made of any plan or programme likely to have a significant effect on the conservation objectives of a site which has been designated or is designated in future. That recital finds expression in Article 6(3) of the directive, which provides inter alia that a plan or project likely to have a significant effect on the site concerned cannot be authorised without a prior assessment of its implications for that site (judgment of 7 September 2004, Waddenvereniging and Vogelbeschermingsvereniging, C‑127/02, EU:C:2004:482, paragraph 22).
