Exclusionary Abuses

Chapter 4 deals with exclusionary abuses under the Competition Act 1998, covering both public and private enforcement cases. The analysis concerns the approach to dominance as well as tests for abuse, focusing on retroactive rebates and bundled discounts, exclusion in multi-market settings, exclusivity, most favoured nation and equivalent clauses, discrimination, and exclusionary abuses in the pharmaceutical sector. This chapter argues that, in its second decade, modern UK competition law continued a trend that was already clear in the first decade: the prohibition of abuse of dominance is applied in a more economically robust and commercially reasonable way than it is by the EU institutions - the Commission and the EU courts - and in certain other Member States. The chapter notes that the third decade of the Competition Act 1998 will see the UK develop its competition policy free from the constraints of EU law and may allow for some divergence in the approach to exclusionary abuses in the future.
