106Although it is for the Commission to prove its allegations that obligations have not been fulfilled and it may not rely on any presumption for that purpose, the existence of a failure to fulfil obligations may nonetheless be proved where it has its origin in the adoption of a legislative or regulatory measure whose existence and application are not contested, by means of a legal analysis of the provisions of that measure (see, to that effect, judgment of 18 June 2020, Commission v Hungary (Transparency of associations), C‑78/18, EU:C:2020:476, paragraphs 36 and 37 and the case-law cited).
