Judgment_paragraph 17 · Republic of Poland v European Parliament and Council of the European Union (C-401/19)

17It must be recalled that partial annulment of an EU act is possible only if the elements for which annulment is sought may be severed from the remainder of the act. In that regard, the Court has repeatedly held that the requirement of severability is not satisfied where the partial annulment of an act would have the effect of altering its substance (judgment of 8 December 2020, Poland v Parliament and Council, C‑626/18, EU:C:2020:1000, paragraph 28 and the case-law cited).
