A Critical Inquiry into ‘Abuse’ in EU Competition Law

Abstract

Abstract Disagreement abounds on what exactly constitutes an ‘abuse’ within article 102 TFEU, EU competition law’s prohibition of an abuse of a dominant position. This situation is highly undesirable, given the important role this prohibition is expected to play in alleviating concerns about substantial market power and its use in important sectors, typified by actions against ‘Big Tech’. This article responds to this problem by analysing and synthesising the jurisprudence of the Court of Justice of the European Union and its evolution to establish the constituent elements of an exclusionary ‘abuse’. The article corrects crucial legal misconceptions, including the putative dichotomy between violations ‘by object’ and ‘by effect’; the assumed disparate legal tests for pricing and non-pricing conduct; and the lost distinction between the ‘as efficient competitor test’ and the ‘as efficient competitor standard’. This critical inquiry allows one to draw concrete predictions on the future development of this challenging, yet vital, area of law.
