Judgment_paragraph 129 · InnoLux Corp. v European Commission (T-91/11)

129Furthermore, it is settled case-law that for the purposes of applying Article 101(1) TFEU, the reason for defining the relevant market is to determine whether an agreement is liable to affect trade between Member States and has as its object or effect the prevention, restriction or distortion of competition within the internal market. Consequently, there is an obligation on the Commission to define the market in a decision applying Article 101(1) TFEU only where it is impossible, without such a definition, to determine whether the agreement, decision by an association of undertakings or concerted practice at issue is liable to affect trade between Member States and has as its object or effect the prevention, restriction or distortion of competition within the internal market (Case T-38/02 Groupe Danone v Commission [2005] ECR II-4407, paragraph 99, and Case T-48/02 Brouwerij Haacht v Commission [2005] ECR II-5259, paragraph 58; see also, to that effect, order of 16 February 2006 in Case C‑111/04 P Adriatica di Navigazione v Commission, not published in the ECR, paragraph 31).
