Judgment_paragraph 40 · Slovak Telekom, a.s. v European Commission (C-165/19 P)

40In order to assess whether those considerations are vitiated by an error of law, as asserted by the appellant, it is important to recall that Article 102 TFEU prohibits any abuse by one or more undertakings of a dominant position within the internal market or in a substantial part of it, in so far as it may affect trade between Member States. A dominant undertaking therefore has a special responsibility not to allow its behaviour to impair genuine, undistorted competition in the internal market (judgment of 30 January 2020, Generics (UK) and Others, C‑307/18, EU:C:2020:52, paragraph 153 and the case-law cited).
