Judgment_paragraph 16 · European Commission v European Parliament and Council of the European Union (C-427/12)

16According to settled case-law of the Court, partial annulment of an EU act is possible only if the elements the annulment of which is sought may be severed from the remainder of the act (see, inter alia, Commission v Council, C‑29/99, EU:C:2002:734, paragraph 45, and Germany v Council, C‑239/01, EU:C:2003:514, paragraph 33). The Court has repeatedly ruled that that requirement of severability is not satisfied where the partial annulment of an act would have the effect of altering its substance (Commission v Poland, C‑504/09 P, EU:C:2012:178, paragraph 98 and the case-law cited).
