Judgment_paragraph 37 · European Commission v Council of the European Union (C-244/17)

37If examination of an EU measure reveals that it pursues two purposes or that it comprises two components and if one of these is identifiable as the main or predominant purpose or component, whereas the other is merely incidental, the measure must be founded on a single legal basis, namely that required by the main or predominant purpose or component. Exceptionally, if it is established, on the other hand, that the measure simultaneously pursues a number of objectives, or has several components, which are inextricably linked without one being incidental to the other, so that various provisions of the Treaty are applicable, the measure must be founded on the various corresponding legal bases (see, to that effect, judgments of 10 January 2006, Commission v Parliament and Council, C‑178/03, EU:C:2006:4, paragraphs 42 and 43; of 11 June 2014, Commission v Council, C‑377/12, EU:C:2014:1903, paragraph 34; and of 14 June 2016, Parliament v Council, C‑263/14, EU:C:2016:435, paragraph 44).
