Judgment_paragraph 27 · MEO – Serviços de Comunicações e Multimédia SA v Autoridade da Concorrência (C-525/16)

27It is only if the behaviour of the undertaking in a dominant position tends, having regard to the whole of the circumstances of the case, to lead to a distortion of competition between those business partners that the discrimination between trade partners which are in a competitive relationship may be regarded as abusive. In such a situation, it cannot, however, be required in addition that proof be adduced of an actual, quantifiable deterioration in the competitive position of the business partners taken individually (judgment of 15 March 2007, British Airways v Commission, C‑95/04 P, EU:C:2007:166, paragraph 145).
