- Dominant position
This chapter discusses the main features of Article 102 of the Treaty on the Functioning of the European Union (TFEU), which is concerned with the abusive conduct of dominant firms. It begins by introducing the European Commission’s Guidance on the Commission’s enforcement priorities in applying Article [102 TFEU] to abusive exclusionary conduct by dominant undertakings. It then discusses the concept of undertaking, the requirement of an effect on trade between Member States, the concept of a dominant position and the requirement that any dominant position must be held in a substantial part of the internal market. The chapter also considers the meaning of abuse of a dominant position, which is a complex and controversial issue. A discussion of the defences to allegations of abuse is followed by a brief look at the consequences of infringing Article 102.
