84Where a competition authority shows that a practice of an undertaking in a dominant position is capable of impairing effective and undistorted competition in the internal market, it remains possible for that undertaking, in order to prevent that practice from being regarded as abuse of a dominant position, to show that that practice is or was justified objectively, either by certain circumstances of the case, which must, inter alia, be external to the undertaking concerned (see, to that effect, judgment of 17 February 2011, TeliaSonera, C‑52/09, EU:C:2011:83, paragraphs 31 and 75), or, having regard to the objective ultimately pursued by Article 102 TFEU, by the interests of consumers (see, inter alia, to that effect, judgment of 30 January 2020, Generics (UK) and Others, C‑307/18, EU:C:2020:52, paragraph 165).
