Judgment_paragraph 36 · Opera Norway AS v European Commission (T-357/24)

36Demonstration by the applicant of a substantial effect on its market position does not entail a definitive ruling on the competitive relationship between that party and the undertaking which has not been designated as a gatekeeper, but requires only that that party adduce pertinent reasons to show that the decision in question may harm its legitimate interests by substantially affecting its position on the market (see, to that effect and by analogy, judgment of 15 July 2021, Deutsche Lufthansa v Commission, C‑453/19 P, EU:C:2021:608, paragraph 57 and the case-law cited).
