116 In the first place, the Court of Justice recalled, in paragraphs 133 to 137 of the judgment on the appeal, the nature and purpose of Article 102 TFEU. Referring in particular to the judgment of 27 March 2012, Post Danmark (C‑209/10, EU:C:2012:172), the Court of Justice, in essence, emphasised that competition on the merits may lead to the exclusion from the market of less efficient competitors (judgment on the appeal, paragraph 134), while recalling the special responsibility on undertakings in a dominant position not to impair genuine, undistorted competition (judgment on the appeal, paragraph 135). Moreover, the Court of Justice pointed out that not all competition by means of price could be regarded as legitimate (judgment on the appeal, paragraph 136).
